Pramin Imipramine Hydrochloride Propafenone Hydrochloride
ModeratePropafenone is broken down in the body by an enzyme called CYP2D6. Imipramine is broken down by the same CYP2D6 enzyme. When the two are taken together, the amount of imipramine in your blood may go up. Other medicines cleared the same way, such as desipramine, haloperidol and venlafaxine, can be affected in the same manner.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
