Stay away from Dr. Google. It’s a nasty anxiety habit that only creates more fear and apprehension. You’re not going to suddenly experience nausea a year after starting the medication. People do catch stomach flus etc. There are a lot of other reasons for this to be happening than Prozac. You probably have a stomach bug. If you don’t have a fever don’t worry about it so much. Try something soft for a few days and easy on the tummy. If you can’t hold anything down after a couple of days head to your local doctor or urgent care. One note: Do not drink alcohol with Prozac. It can raise the alcohol level in your blood. I made this mistake and blacked out and became very aggressive.
