Interactions between your drugs
buPROPion vadadustat
Applies to: bupropion / dextromethorphan and vadadustat
Consumer information for this interaction is not currently available.
MONITOR CLOSELY: The use of bupropion is associated with a dose-related risk of seizures. The risk may be further increased when coadministered with selective serotonin reuptake inhibitors (SSRI antidepressants or anorectics), monoamine oxidase inhibitors, neuroleptic agents, central nervous system stimulants, opioids, tricyclic antidepressants, other tricyclic compounds (e.g., cyclobenzaprine, phenothiazines), systemic steroids, or any substance that can reduce the seizure threshold (e.g., carbapenems, cholinergic agents, fluoroquinolones, interferons, chloroquine, mefloquine, lindane, theophylline). These agents are often individually epileptogenic and may have additive effects when combined. The estimated incidence of seizures is approximately 0.4% for immediate-release bupropion hydrochloride at dosages between 300 to 450 mg/day (equivalent to 348 to 522 mg/day of bupropion hydrobromide), but increases almost tenfold between 450 mg and 600 mg/day (equivalent to 522 and 696 mg/day of bupropion hydrobromide). Data for sustained-release (SR) bupropion hydrochloride revealed a seizure incidence of approximately 0.1% at dosages up to 300 mg/day and 0.4% at 400 mg/day. Likewise, in clinical trials, an overall seizure incidence of approximately 0.1% has been reported with extended-release (XL) bupropion hydrochloride at dosages up to 450 mg/day and approximately 0.39% at 450 mg/day. The 0.4% seizure incidence may exceed that of other marketed antidepressants by as much as 4-fold.
MANAGEMENT: Extreme caution is advised if bupropion is administered with any substance that can reduce the seizure threshold, particularly in the elderly and in patients with a history of seizures or other risk factors for seizures (e.g., head trauma; brain tumor; severe hepatic cirrhosis; metabolic disorders; CNS infections; excessive use of alcohol or sedatives; addiction to opiates, cocaine, or stimulants; diabetes treated with oral hypoglycemic agents or insulin). Bupropion as well as concomitant medications should be initiated at the lower end of the dosage range and titrated gradually as needed and as tolerated. The maximum recommended dosage for the specific bupropion formulation should not be exceeded. Bupropion should be discontinued and not restarted in patients who experience a seizure during treatment.
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.
Drug and food interactions
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.
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.
vadadustat food
Applies to: vadadustat
Consumer information for this interaction is not currently available.
MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.
MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.
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.
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.
