Interactions between your drugs
buPROPion dextroamphetamine
Applies to: bupropion and Dexedrine (dextroamphetamine)
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with inhibitors of CYP450 2D6 may increase the plasma concentrations as well as the pharmacologic and adverse effects of amphetamines. The proposed mechanism involves the inhibition of CYP450 2D6, an isoenzyme partially responsible for the metabolic clearance of certain amphetamines. Furthermore, because CYP450 2D6 is genetically polymorphic, variations in amphetamine metabolism across populations may either increase or decrease the risk associated with this interaction. Increased exposure to amphetamines may potentiate the risk of serious adverse reactions such as serotonin syndrome, seizures, psychiatric adverse reactions (e.g., new psychotic or manic symptoms), peripheral vasculopathy (including Raynaud's Phenomenon), and cardiovascular effects (e.g., hypertension, tachycardia). However, data evaluating the interaction are not available.
MANAGEMENT: Caution and closer monitoring for adverse effects are recommended when amphetamines are used concurrently with CYP450 2D6 inhibitors, and a reduction in the initial amphetamine dose should be considered. Patients should be more closely monitored for signs and symptoms of serotonin syndrome, particularly during the initiation of amphetamine therapy and following any dosage increases. Additional caution is advised when amphetamines are coadministered with CYP450 2D6 inhibitors that lower the seizure threshold (e.g., bupropion). Patients should be instructed to notify their healthcare provider if they experience increased amphetamine-related side effects, such as seizures, cardiovascular effects (e.g., hypertension, tachycardia), or symptoms of serotonin syndrome (e.g., mental status changes, autonomic dysfunction like tachycardia or hyperthermia, neuromuscular abnormalities such as hyperreflexia, or gastrointestinal symptoms).
Drug and food interactions
buPROPion food
Applies to: bupropion
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.
dextroamphetamine food
Applies to: Dexedrine (dextroamphetamine)
Using dextroamphetamine together with alcohol can increase the risk of cardiovascular side effects such as increased heart rate, chest pain, or blood pressure changes. You should avoid or limit the use of alcohol while being treated with dextroamphetamine. Let your doctor know if you experience severe or frequent headaches, chest pain, and/or a fast or pounding heartbeat. 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
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
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.
