It's probably worth mentioning ibuprofen and aspirin have interactions with SSRIs like fluoxetine, because some of us are on antidepressants. They can cause internal bleeding. In fact SSRIs interact with over 1000 other medications.
You can google "drug interactions" and you'll find
drugs.com, rxlist and webmd. You can list all the drugs you're on and they will tell you minor or serious interactions. Hint: use all three to get a full picture.
As I found out last weekend, fluoxetine and Phenergan (promethazine) do NOT go together. I assumed an antihistamine was innocuous - wow was I wrong, I lost motor and cognitive function. Drug interactions are not something you want to fool with.
