In pharmacokinetic study, administration of a single dose of roflumilast in patients receiving another CYP3A4 inducer, rifampin, resulted in decreased roflumilast Cmax and AUC, as well as increased Cmax and decreased AUC of the active metabolite roflumilast N-oxide. Coadministration of CYP3A4 inducers, like barbiturates, may decrease systemic concentrations of romidepsin. Use caution when concomitant administration of these agents is necessary.

Moderate Coadministration of ropinirole and barbiturates may result in decreased concentrations of ropinirole. If therapy with barbiturates is initiated or discontinued during treatment with ropinirole, adjustment of ropinirole dose may be required.

Also, somnolence is a commonly reported adverse effect of ropinirole; coadministration of ropinirole with barbiturates may result in additive sedative effects. Moderate Dopaminergic medications, including safinamide, may cause a sudden onset of somnolence which sometimes has resulted in motor vehicle accidents.

Patients may not perceive warning signs, such as excessive drowsiness, or they may report feeling alert immediately prior to the event. Because of possible additive effects, advise patients about the potential for increased somnolence during concurrent use of safinamide with other sedating medications, such as barbiturates.

Major Coadministration with phenobarbital and, potentially, other barbiturates may increase the metabolism of saquinavir and lead to decreased saquinavir concentrations resulting in reduction of antiretroviral efficacy and development of viral resistance.

If saquinavir and barbiturates are used together, the patient must be closely monitored for antiviral efficacy. Drugs that induce hepatic isoenzymes, such as barbiturates could decrease sertraline plasma concentrations, potentially causing decreased effectiveness of this SSRI. It can be expected that concomitant administration of CYP3A4 enzyme-inducers will decrease plasma levels of sildenafil, however, no interaction studies have been performed.

Major Concomitant use of sirolimus and barbiturates should be avoided. Barbiturates such as phenobarbital and primidone may decrease the systemic exposure of sirolimus. Consider alternative agents with less potential for interaction.

If concurrent use cannot be avoided, monitor sirolimus plasma concentrations closely and adjust the dose as necessary. A similar interaction with sirolimus would be expected with all other barbiturates. In addition, the exposure of sirolimus may be altered via P-glycoprotein P-gp transport. Sirolimus is P-gp substrate; primidone and phenobarbital may induce P-gp. Moderate Additive CNS depression may occur if barbiturates are used concomitantly with skeletal muscle relaxants.

Caution should be exercised during concomitant use of skeletal muscle relaxants and barbiturates; dosage reduction of one or both agents may be necessary. Severe Sodium oxybate should not be used in combination with CNS depressant anxiolytics, sedatives, and hypnotics or other sedative CNS depressant drugs.

Specifically, sodium oxybate use is contraindicated in patients being treated with sedative hypnotic drugs. Sodium oxybate GHB has the potential to impair cognitive and motor skills. For example, the concomitant use of barbiturates and benzodiazepines increases sleep duration and may contribute to rapid onset, pronounced CNS depression, respiratory depression, or coma when combined with sodium oxybate.

Avoid the use of sorafenib with a strong CYP3A4 inducer. If a strong CYP3A4 inducer must be coadministered with sorafenib, consider a sorafenib dose increase. John's Wort, Hypericum perforatum: John's wort, Hypericum perforatum, may intensify or prolong the effects of general anesthetics; profound hypotension has also been reported.

In one report, the authors recommend that patients should discontinue taking St. John's Wort at least 5 days prior to anesthesia. The American Society of Anesthesiologists has recommended that patients stop taking herbal medications at least 2 to 3 weeks before surgery to decrease the risk of adverse reactions. Moderate Patients receiving general anesthetics should be observed for exaggerated effects if they are receiving streptomycin.

Additionally, concurrent use of sufentanil with barbiturates may decrease sufentanil plasma concentrations, decrease opioid efficacy, and potentially lead to a withdrawal syndrome in those with physical dependence to opioid agonists.

Barbiturates are inducers of CYP3A4, an isoenzyme partially responsible for the metabolism of sufentanil. Major Avoid coadministration of methohexital with sunitinib if possible due to decreased exposure to sunitinib which could decrease efficacy. If concomitant use is unavoidable, consider increasing the dose of sunitinib in The maximum daily dose administered in the pNET study was 50 mg.

Moderate Monitor for decreased efficacy of suvorexant if coadministration with a barbiturate is necessary. Additive CNS effects, such as sedation and psychomotor impairment, are also possible. Dosage adjustments of suvorexant and of concomitant CNS depressants may be necessary when administered together because of potentially additive effects. The use of suvorexant with other drugs to treat insomnia is not recommended.

The risk of next-day impairment, including impaired driving, is increased if suvorexant is taken with other CNS depressants. Patients should be cautioned against driving and other activities requiring complete mental alertness. Moderate Cholinesterase inhibitors are also likely to exaggerate muscle relaxation under general anesthetics. Major Drugs such as barbiturates, which can induce cytochrome P 3A4, may decrease whole blood concentrations of tacrolimus.

Monitoring of tacrolimus whole blood concentrations and appropriate dosage adjustments of tacrolimus are recommended. Moderate Tamoxifen and its metabolite, 4-hydroxytamoxifen, are metabolized by the cytochrome P 3A4 isoenzyme. Barbiturates may induce the metabolism of tamoxifen, potentially leading to a decrease in clinical effectiveness. If tapentadol is initiated in a patient taking a barbiturate, reduce initial dosage and titrate to clinical response. Major Concurrent use of tasimelteon and strong inducers of CYP3A4, such as barbiturates or primidone, should be avoided.

Because tasimelteon is partially metabolized via CYP3A4, a large decrease in exposure is possible with the potential for reduced efficacy. Barbiturates also induce CYP1A2, a secondary metabolic pathway of tasimelteon. Moderate Due to the risk for breakthrough fungal infections, caution is advised when administering terbinafine with barbiturates.

Although this interaction has not been studied by the manufacturer, and published literature suggests the potential for interactions to be low, taking these drugs together may decrease the systemic exposure of terbinafine. Predictions about the interaction can be made based on the metabolic pathways of both drugs.

Monitor patients for breakthrough fungal infections. Major The use of barbiturate anxiolytics, sedatives, or hypnotics with thalidomide may cause an additive sedative effect and should be avoided. Thalidomide frequently causes drowsiness and somnolence. Dose reductions may be required.

Patients should be instructed to avoid situations where drowsiness may be a problem and not to take other medications that may cause drowsiness without adequate medical advice. Moderate The metabolism of aminophylline can be increased by concurrent use with barbiturates.

Patients should be monitored for loss of therapeutic effect if a barbiturate is added is added to aminophylline therapy. Conversely, the hypnotic effects of barbiturates can be reduced by aminophylline. Moderate The metabolism of theophylline can be increased by concurrent use with barbiturates.

Patients should be monitored for loss of therapeutic effect if a barbiturate is added is added to theophylline therapy. Conversely, the hypnotic effects of barbiturates can be reduced by theophylline. Moderate Thiothixene can potentiate the CNS-depressant action of other drugs such as methohexital. Minor Hepatic enzyme-inducing drugs, including barbiturates, can increase the catabolism of thyroid hormones.

Be alert for a decreased response to thyroid replacement agents with dosage adjustments, discontinuation or addition of barbiturates during thyroid hormone replacement therapy. Major Barbiturates increase the metabolism of tipranavir, and may lead to decreased efficacy of tipranavir.

In addition, tipranavir may inhibit the CYP metabolism of barbiturates, resulting in increased barbiturate concentrations. Anticonvulsant serum concentrations should be monitored closely if these agents are added; the patient should be observed for changes in the clinical efficacy of the antiretroviral or anticonvulsant regimen Tizanidine: Moderate Patients receiving general anesthetics should be observed for exaggerated effects if they are receiving tobramycin.

Major Barbiturates have been shown to enhance the hepatic clearance of verapamil. The effect on oral verapamil is greater than for IV verapamil, but a significant increase in clearance has been noted for both verapamil dosage forms during concomitant administration of a barbiturate. Patients receiving verapamil should be monitored for loss of therapeutic effect if barbiturates are added.

Monitor for decreased clinical effects of tretinoin, ATRA while receiving concomitant therapy. Additionally, barbiturates may increase the metabolism of triazolam.

Triazolam is a CYP3A4 substrate. Moderate Tricyclic antidepressants TCAs , when used concomitantly with anticonvulsants, can increase CNS depression and may also lower the seizure threshold, leading to pharmacodynamic interactions.

In addition, pharmacokinetic interactions may occur. Barbiturates may increase TCA metabolism. Monitor patients during concurrent use. Moderate The concurrent use of trimethobenzamide with barbiturates may potentiate the CNS effects of either trimethobenzamide or the barbiturate.

Minor Drugs such as barbiturates can increase the metabolism of trimetrexate by induction of the hepatic cytochrome P system. This can lead to lower plasma concentrations of trimetrexate.

Moderate Additive CNS depression may occur if barbiturates are used concomitantly with triprolidine. Moderate General anesthetics may potentiate the hypotension associated alatrofloxacin administration. Concomitant use may decrease the plasma concentration and effectiveness of ulipristal. Strong CYP3A4 inducers can decrease systemic exposure of valbenazine and its active metabolite compared to the use of valbenazine alone.

Reduced exposure of valbenazine and its active metabolite may reduce efficacy. Major Any substances that act on the CNS, including psychoactive drugs and drugs used as anesthetic adjuvants e. The valerian derivative, dihydrovaltrate, binds at barbiturate binding sites; valerenic acid has been shown to inhibit enzyme-induced breakdown of GABA in the brain; the non-volatile monoterpenes valepotriates have sedative activity.

These interactions are probably pharmacodynamic in nature. There is a possibility of interaction with valerian at normal prescription dosages of anxiolytics, sedatives, and hypnotics including barbiturates and benzodiazepines. Patients taking medications such as tricyclic antidepressants, lithium, MAOIs, skeletal muscle relaxants, SSRIs and serotonin norepinephrine reuptake inhibitors e. Patients should not abruptly stop taking their prescribed psychoactive medications. Valproic Acid, Divalproex Sodium: Moderate Valproic acid has been shown to inhibit the hepatic metabolism of phenobarbital.

It is likely that other barbiturates, like methohexital, would be affected similarly by valproic acid. Patients should be monitored for an exaggerated barbiturate effect if valproic acid is used concomitantly. Moderate The concurrent administration of vancomycin and anesthetics has been associated with erythema, histamine-like flushing, and anaphylactoid reactions.

Moderate Use caution if coadministration of vandetanib with methohexital is necessary, due to a possibly unpredictable effect on vandetanib efficacy and toxicity. Minor Vardenafil is metabolized by cytochrome P 3A4. It can be expected that concomitant administration of CYP3A4 enzyme-inducers, such as barbiturates, will decrease plasma levels of vardenafil. Moderate Vigabatrin may cause somnolence and fatigue. Drugs that can cause CNS depression, if used concomitantly with vigabatrin, may increase both the frequency and the intensity of adverse effects such as drowsiness, sedation, and dizziness.

Caution should be used when vigabatrin is given with barbiturates. Major Monitor for additive CNS depressive effects and for reduced effect of vilazodone. Because CYP3A4 is the primary isoenzyme involved in the metabolism of vilazodone, decreased plasma concentrations of the drug are expected during coadministration with potent inducers of CYP3A4 such as barbiturates. After discontinuation of the CYP3A4 inducer, resume the previous vilazodone dose over 1 to 2 weeks.

Agents that induce CYP 3A4 may increase the metabolism of vincristine and decrease the efficacy of drug, including barbiturates. Patients receiving these drugs concurrently should be monitored for possible loss of vincristine efficacy.

Moderate Use caution during concurrent use of vorapaxar and other barbiturates. Vorapaxar is a CYP3A4 substrate. Decreased serum concentrations of vorapaxar and thus decreased efficacy are possible during concurrent use.

Major Patients should be monitored for a decreased response to vortioxetine when barbiturates are co-administered. The manufacturer recommends that the practitioner consider an increase in dose of vortioxetine when a strong CYP inducer is co-administered for more than 14 days.

In such cases, the maximum recommended dose of vortioxetine should not exceed three times the original dose. When the inducer is discontinued, the dose of vortioxetine should be reduced to the original level within 14 days.

Major A serious drug interaction can occur between barbiturates and warfarin. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency. The following laboratory tests may be affected in patients who are receiving promethazine: Diagnostic pregnancy tests based on immunological reactions between HCG and anti-HCG may result in false-negative or false-positive interpretations.

An increase in blood glucose has been reported in patients receiving promethazine. Addiction, abuse, and misuse [see Warnings and Precautions 5.

Because these reactions may be reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Sedation somnolence, mental clouding, lethargy , impaired mental and physical performance, lightheadedness, dizziness, headache, dry mouth, nausea, vomiting, constipation, shortness of breath, sweating, tachycardia, arrhythmias including premature ventricular contractions, CNS stimulation including anxiety, restlessness, nervousness, tremor, and irritability.

Body as a whole: Coma, death, fatigue, falling injuries, hyperactivity, hyperthermia, lethargy, weakness. Peripheral edema, atrial fibrillation, myocardial infarction, increased blood pressure, decreased blood pressure, tachycardia, chest pain, palpitation, syncope, orthostatic hypotension, prolonged QT interval, hot flush. Ataxia, confusion, diplopia, facial dyskinesia, insomnia, migraine, increased intracranial pressure, seizure, tinnitus, tremor, vertigo.

Flushing, hyperhidrosis, photosensitivity, pruritus, rash, urticaria. Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology Abdominal pain, bowel obstruction, decreased appetite, diarrhea, difficulty swallowing, dry mouth, GERD, indigestion, dysguesia, ischemic colitis, jaundice, pancreatitis, paralytic ileus, biliary tract spasm spasm of the sphincter of Oddi.

Urinary tract infection, ureteral spasm, spasm of vesicle sphincters, urinary retention. Bone-marrow suppression, agranulocytosis, aplastic anemia, and thrombocytopenia have been reported. Increases in serum amylase. Arthralgia, backache, muscle spasm. Blurred vision, miosis constricted pupils , mydriasis dilated pupils , visual disturbances.

Dystonias, torticollis, tongue protrusion, hyperexcitability, and abnormal movements have been reported following a single administration of promethazine. Agitation, anxiety, confusion, fear, dysphoria, depression, hallucinations. Apnea, bronchitis, cough, dry nose, dry throat, dyspnea, nasal congestion, nasopharyngitis, respiratory depression, sinusitis, thickening of bronchial secretions, tightness of chest and wheezing, upper respiratory tract infection. Drug abuse, drug dependence, Neuroleptic Malignant Syndrome, opioid withdrawal syndrome.

Inhibitors of CYP3A4 The concomitant use of Promethazine VC with Codeine Oral Solution with CYP3A4 inhibitors, such as macrolide antibiotics eg, erythromycin , azole-antifungal agents eg, ketoconazole , or protease inhibitors eg, ritonavir , may result in an increase in codeine plasma concentrations with subsequently greater metabolism by cytochrome CYP2D6, resulting in greater morphine levels, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of Promethazine VC with Codeine Oral Solution is achieved [see Warnings and Precautions 5.

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, it may result in lower codeine levels, greater norcodeine levels, and less metabolism via CYP2D6 with resultant lower morphine levels [see Clinical Pharmacology If concomitant use is necessary, monitor patients for respiratory depression and sedation at frequent intervals.

After stopping a CYP3A4 inducer, as the effects of the inducer decline, codeine plasma concentrations may increase with subsequently greater metabolism by cytochrome CYP2D6, resulting in greater morphine levels [see Clinical Pharmacology If concomitant use of a CYP3A4 inducer is necessary, follow the patient for reduced efficacy.

The concomitant use of Promethazine VC with Codeine Oral Solution and CYP2D6 inhibitors, such as paroxetine, fluoxetine, bupropion, or quinidine, can increase the plasma concentration of codeine, but can decrease the plasma concentration of active metabolite morphine, which could result in reduced efficacy [see Clinical Pharmacology After stopping a CYP2D6 inhibitor, as the effects of the inhibitor decline, the codeine plasma concentration will decrease but the active metabolite morphine plasma concentration will increase, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression [see Clinical Pharmacology Serotonergic Drugs The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome.

If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation. MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity eg, respiratory depression, coma [see Warnings and Precautions 5.

The cardiac pressor response may be potentiated and acute hypertensive crisis may occur when phenylephrine containing preparations are used with prior administration of MAOIs [see Warnings and Precautions 5. Drug interactions, including an increased incidence of extrapyramidal effects, have been reported when some MAOI and phenothiazines are used concomitantly.

Muscle Relaxants Codeine may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. If concomitant use is necessary, monitor patients for signs of respiratory depression that may be greater than otherwise expected.

Diuretics Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone. Monitor patients for signs of urinary retention or reduced gastric motility when Promethazine VC with Codeine Oral Solution is used concomitantly with anticholinergic drugs. Additive adverse effects resulting from cholinergic blockade eg, xerostomia, blurred vision, or constipation may occur when anticholinergic drugs are administered with promethazine.

Antihypertensive Drugs Due to the antagonistic pharmacologic effects of phenylephrine, one of the active ingredients in Promethazine VC with Codeine Oral Solution, the concomitant use of Promethazine VC with Codeine Oral Solution with antihypertensive drugs, including alpha-adrenergic antagonists eg, phentolamine ; mixed alpha- and beta-adrenoreceptor antagonists; calcium channel blockers eg, nifedipine ; ACE inhibitors; and centrally acting sympatholytic agents eg, guanfacine, reserpine may reduce their antihypertensive effects.

Interactions that Augment the Pressor Effect of Phenylephrine The concomitant use of Promethazine VC with Codeine Oral Solution with ergot alkaloids eg, methylergonovine maleate ; atropine sulfate; steroids eg, hydrocortisone ; angiotensin; aldosterone; norepinephrine transporter inhibitors eg, atomoxetine ; and tricyclic antidepressants may enhance the pressor response and increase the risk of hypertension.

Sympathomimetic Agents Due to synergistic adrenergic effects of phenylephrine, one of the active ingredients in Promethazine VC with Codeine Oral Solution, the concomitant use of Promethazine VC with Codeine Oral Solution with sympathomimetic amines such as epinephrine, amphetamine, phenylpropanolamine, and bronchodilator beta2-adrenoreceptor agonists may result in tachycardia, arrhythmias, serious hypertensive response and possible stroke.

Prolonged use of opioids during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions 5. There are no available data with Promethazine VC with Codeine Oral Solution use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. Published studies with codeine have reported inconsistent findings and have important methodological limitations see Data.

There are reports of respiratory depression when codeine is used during labor and delivery see Clinical Considerations. Reproductive toxicity studies have not been conducted with Promethazine VC with Codeine Oral Solution; however, studies are available with individual active ingredients see Data. In animal reproduction studies, codeine administered by the oral route to pregnant rats during the period of organogenesis increased resorptions and decreased fetal weights at a dose approximately 26 times the maximum recommended human dose MRHD in the presence of maternal toxicity see Data.

For pregnant mice and rats that received promethazine at doses 0. In studies with normotensive pregnant rabbits, which received phenylephrine during the period of organogenesis or later, there were findings of increased fetal lethality, adverse placental effects, and possible teratogenic effects at subcutaneous doses approximately 0.

Premature labor was also observed when treatment was initiated during the second trimester or later see Data. Based on the animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn.

Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Where can I get more information? Your pharmacist can provide more information about acetaminophen, butalbital, caffeine, and codeine. Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.

If you are taking this medication 3 times a day to control seizures , do not let more than 12 hours pass between doses because your seizures may increase.

Do not take this medication more often or increase your dose without consulting your doctor. Your condition will not improve any faster and the risk of serious side effects may increase. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased. Antacids containing aluminum or magnesium may interfere with the absorption of this medication.

Caution should be exercised during simultaneous use of these agents due to potential excessive CNS effects or additive hypotension. Moderate Muscle relaxation produced by succinylcholine can be prolonged when the drug is administered with a cholinesterase inhibitor. If used during surgery, extended respiratory depression could result from prolonged neuromuscular blockade. Other neuromuscular blockers may interact with cholinesterase inhibitors in a similar fashion.

Cholinesterase inhibitors are therefore also likely to exaggerate muscle relaxation under general anesthetics. Moderate Clobazam, a benzodiazepine, may cause drowsiness or other CNS effects. Potentiation of CNS effects i. Moderate Clozapine can potentiate the actions of other CNS depressants such as the general anesthetics. Caution should be exercised with simultaneous use of these agents due to potential excessive CNS effects. Moderate Coadministration of dexmedetomidine with general anesthetics is likely to lead to an enhancement of anesthetic, sedative, or cardiovascular effects.

Due to possible pharmacodynamic interactions, when co-administered with dexmedetomidine, a reduction in dosage of dexmedetomidine or the concomitant anesthetic may be required. Specific studies have confirmed these pharmacodynamic effects with sevoflurane, isoflurane, and propofol. No pharmacokinetic interactions between dexmedetomidine and isoflurane or propofol have been demonstrated. It may be prudent to avoid coadministration of ketamine with memantine.

If coadministration cannot be avoided, monitor for increased adverse effects such as agitation, dizziness and other CNS events. Moderate Concomitant use of dronabinol with other CNS depressants like general anesthetics can potentiate the effects of dronabinol on respiratory depression. Major Central nervous system CNS depressants e.

Following administration of droperidol, the dose of the other CNS depressant should be reduced. Moderate Methylxanthines and inhaled general anesthetics have been associated with adverse cardiovascular effects. Concurrent use may increase the risk of such effects including cardiac arrhythmias. Major General anesthetics may sensitize the myocardium to the effects of sympathomimetics, including ephedrine. Moderate A temporary dose reduction of eszopiclone should be considered following administration of general anesthetics.

The risk of next-day psychomotor impairment is increased during co-administration of eszopiclone and other CNS depressants, which may decrease the ability to perform tasks requiring full mental alertness such as driving. Major Alcohol is associated with CNS depression.

The combined use of alcohol and CNS depressants can lead to additive CNS depression, which could be dangerous in tasks requiring mental alertness and fatal in overdose. Alcohol taken with other CNS depressants can lead to additive respiratory depression, hypotension, profound sedation, or coma.

Consider the patient's use of alcohol or illicit drugs when prescribing CNS depressant medications. In many cases, the patient should receive a lower dose of the CNS depressant initially if the patient is not likely to be compliant with avoiding alcohol. Major Concomitant use of fentanyl with other CNS depressants, such as general anesthetics, may cause respiratory depression, hypotension, and profound sedation; a coma could result. Blood pressure and respiration monitoring to ensure the absence of hypotension and respiratory depression, respectively may be desirable.

Moderate Patients receiving general anesthetics should be observed for exaggerated effects if they are receiving gentamicin. Major Haloperidol can potentiate the actions of other CNS depressants such as general anesthetics. Hydrocodone; Potassium Guaiacolsulfonate; Pseudoephedrine: Moderate Concomitant use of hydromorphone with other central nervous system CNS depressants can potentiate the effects of hydromorphone and may lead to additive CNS or respiratory depression, profound sedation, or coma.

Examples of drugs associated with CNS depression include general anesthetics. Prior to concurrent use of hydromorphone in patients taking a CNS depressant, assess the level of tolerance to CNS depression that has developed, the duration of use, and the patient's overall response to treatment. Carefully monitor the patient for hypotension, CNS depression, and respiratory depression.

Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. Moderate General anesthesia may be indicated in the performance of some procedures in young or uncooperative children and in selected adult patients; however, a higher incidence of adverse reactions has been reported to ionic contrast media in these patients. Codeine and morphine passes into breast milk. If you take other medicines This medicine contains paracetamol. Do not take anything else containing paracetamol while taking this medicine.
