Certain Arrhythmia Medications
Bupropion may raise the levels of certain arrhythmia medications in your blood, increasing your risk of side effects. If you are taking these drugs together, your healthcare provider may need to monitor you more closely -- especially when you are starting or stopping bupropion.
Cyclophosphamide (Cytoxan)
While it is thought that
cyclophosphamide may interact with bupropion, there have been no reports of such an interaction in actual patients. If you are taking cyclophosphamide along with bupropion, your healthcare provider may need to monitor you more closely and may need to adjust your doses of these medications.
Doxorubicin (Adriamycin, Doxil)
Doxorubicin may raise the level of bupropion in your blood, increasing your chances of side effects. Your healthcare provider may need to decrease your bupropion dose while you are taking doxorubicin.
Efavirenz (Sustiva)
While it is thought that
efavirenz may interact with bupropion, there have been no reports of such an interaction in actual patients. If you are taking efavirenz along with bupropion, your healthcare provider may need to monitor you more closely and may need to adjust your doses of these medications.
Levodopa (Parcopa, Sinemet, Sinemet CR, Stalevo)
Taking bupropion and levodopa together may increase your risk of side effects. Your healthcare provider may decide to start you at a lower bupropion dose if you are taking levodopa.
Monoamine Oxidase Inhibitors (MAOIs)
You should not take bupropion if you have taken an MAOI within the past 14 days, due to the increased risk of dangerous side effects.
Nelfinavir (Viracept)
While it is thought that
nelfinavir may interact with bupropion, there have been no reports of such an interaction in actual patients. If you are taking nelfinavir along with bupropion, your healthcare provider may need to monitor you more closely and may need to adjust your doses of these medications.
