I take losartan 50mg for blood pressure. can i take a multivitamin and a b complex vitamin with it?

Losartan interaction: The main interaction with Losartan would be taking any large amount of Potassium, which may be a part of your multivitamin. I might also be concerned that you want to take both a multivitamin and a B-complex vitamin. Potential is there for excess B vitamins. If possible, have a consultation with your pharmacist to discuss the specific multivitamin and possible interactions.
