Hi everybody.

I currently take metformin, losartan, omeprazole and mirtazapine. I've been feeling a bit run down and suffer with regular colds, and thought about taking a multi-vitamin and maybe a garlic supplement. I've done a Google search, but couldn't find much (my google-fu is weak). I will speak to my doctor, but I can't get an appointment for over 2 weeks.

Anybody know of any possible problems?

Here are two options:

1) Interaction checker (http://www.drugs.com/drug_interactions.html) here you can enter the drugs you are taking and a database will check for possible interactions.
2) Call the issuing pharmacy. They are always happy to assist with this type of query and know the questions to ask.

Thanks Dr Bill. I hadn't thought of checking with the pharmacist, I'll call them in the morning.
