Mysimba can interact with other medicines, requiring careful management of co‑administration. Major Interactions (Avoid): - MAO inhibitors: risk of hypertensive crisis; must be discontinued at least 14 days before starting Mysimba. - Other bupropion‑containing products: increased risk of seizures. - Opioid agonists (e.g., morphine, oxycodone): naltrexone blocks analgesic effect, leading to loss of pain control. Moderate Interactions (Monitor Closely): - CYP2B6 inhibitors or inducers (e.g., ritonavir, carbamazepine): may alter bupropion plasma levels. - Antihypertensive agents: additive blood pressure‑lowering effect may require dose adjustment.
