You are welcome. I found some more drug interaction checker websites. See the list below. They are easy to use. Your local pharmacist may also be able to check interactions for you. Some drug companies that make cancer medicines have patient lines where we may be able to ask questions about side effects and possible drug interactions when doctors can't do that for you.
