The main drug that could interact negatively with Minoxidil (Loniten) is Ismelin. You should talk to your doctor about that and any other medications you may already be on to assess possible side effects that may result. Certain drugs may cause the Minoxidil (Loniten) to decrease in potency, thereby making you take more to make up for what you lack. You also need to talk about any vitamins or minerals you may be taking as those could have a poor interaction with Minoxidil (Loniten).
