I take a 20mg capsule of fluoxetine every morning (usually around 9am). This evening I had a really stupid moment, and I took another one of my pills (instead of the ibuprofen I actually wanted to take). My original dosage was at 9am today, and it is now 18:30 pm. I don't know what happens, but is there any danger to this. The pills were taken about 9 hours apart, so I don't know if there'll be any effects?? Any help will be greatly appreciated.
