I was diagnosed with gastritis and I was taking penicillin before getting it. I started taking the penicillin because I had dental implants done. I don t know if I should take the penicillin anymore because of the recent gastritis, but I need it for my implant surgery. What do I do? I had some Drs tell me that penicillin is an antibiotic, and the Dr that diagnosed me with the gastritis said not to take any anti inflammatory medication because it will harm my gastritis. I have stiches all across my bottom gums because of the surgery, and I need to do something to stop the infection from coming. Isn t penicillin another form of an anti inflammatory? If so, I was told to not use anti inflammatories?? What do I do??
