Hi Dr: I am a 36 year old male. I have experienced hair loss and I would like to try Propecia (Finasteride). However, I am a heart patient and I take Toprol, Altace, Zetia, Plavix, Lipitor. Will the propecia interact with any of these? I have read that it may interact with blood pressure meds.
If you are taking finasteride at the 1mg dose (Propecia), I would not worry about cross-reactivity. The official site does not mention a problem with the medications you listed. Minoxidil on the other hand, is an anti-hypertensive agent so if you mix it with the anti-hypertensive medication you take, you could drop your blood pressure further.
