Interactions between your drugs

Moderate

buPROPion dextromethorphan

Applies to: bupropion / dextromethorphan and bupropion / dextromethorphan

BuPROPion may increase the blood levels and effects of dextromethorphan. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience increased side effects or your condition changes. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

buPROPion tedizolid

Applies to: bupropion / dextromethorphan and tedizolid

Consumer information for this interaction is not currently available.

MONITOR: The concurrent use of tedizolid with agents that have serotonergic activity including serotonin reuptake inhibitors, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants, 5-HT1 receptor agonists, ergot alkaloids, cyclobenzaprine, lithium, St. John's wort, phenylpiperidine opioids, dextromethorphan, and tryptophan may elevate the risk of developing serotonin syndrome. The proposed mechanism is tedizolid-mediated non-selective and reversible inhibition of monoamine oxidase (MAO), with more potent inhibition of MAO-A than linezolid in vitro. In a retrospective cohort study from January 2015 to July 2023 of 479 adult patients receiving tedizolid, 62% (297/479) received concomitant serotonergic agents, but suspected serotonin syndrome requiring tedizolid discontinuation was found to be rare, occurring in only 0.4% (2/479) of cases. Symptoms of serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucination, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, unstable blood pressure, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea.

MANAGEMENT: Caution and closer monitoring for serotonin syndrome are recommended during concomitant treatment with tedizolid and serotonergic agents, especially during dose escalations, and patients should be instructed to notify their healthcare provider if they experience symptoms of serotonin syndrome. Due to variability and occasionally prolonged half-lives of these coadministered agents, consulting individual product labeling for specific guidance is advised. If serotonin syndrome is suspected, discontinuation of therapy or dose reductions should be considered depending on the severity of the symptoms, and supportive care should be provided. Moderately ill patients may benefit from serotonin antagonists like cyproheptadine or chlorpromazine. Severe cases require consultation with a toxicologist and may need sedation, neuromuscular paralysis, intubation, and mechanical ventilation.

Drug and food interactions

Moderate

buPROPion food

Applies to: bupropion / dextromethorphan

Using buPROPion with alcohol may increase the risk of uncommon side effects such as seizures, hallucinations, delusions, paranoia, mood and behavioral changes, depression, suicidal thoughts, anxiety, and panic attacks. On the other hand, sudden withdrawal from alcohol following regular or chronic use can also increase your risk of seizures during treatment with buPROPion. If you are prone to frequent or excessive alcohol use, talk to your doctor before starting buPROPion. In general, you should avoid or limit the use of alcohol while being treated with buPROPion. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

dextromethorphan food

Applies to: bupropion / dextromethorphan

Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate

buPROPion food

Applies to: bupropion / dextromethorphan

Both buPROPion and caffeine can increase blood pressure. And using them together may have additive effects. Talk to your doctor if you have any questions or concerns, particularly if you have a history of high blood pressure or heart disease. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

buPROPion food

Applies to: bupropion / dextromethorphan

Using buPROPion and nicotine together can cause an increase in blood pressure. This can cause dizziness, confusion, uneven heartbeats, and chest pain. If you take both medications together, tell your doctor if you have any of these symptoms. You may need a dose adjustment or need your blood pressure checked more often if you take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
