I've just started 20mg omeprazole for suspected stomach ulcer. How long do side effects last. Feeling nauseous, shaky and exhausted. Are these normal side effects

    Quite normal, max for 2 weeks in my opinion but they should be diminishing slowly... If things don't get better, then go to your GP to change the drug. I had terrible bloatnes and then I stopped with the drug for 3 days and then continued on it after 3 days and everything was fine then. Remember, we are all different, but you'll find out how to manage the situation..

    Yes these are just a few of the many side effects of this poison. My advice is to read as much as possible about this horrible drug before getting in too deep. I was on it and Lansoprazole (prevacid) for more than three years and had every side effect u can think of. Weight loss,heart palpitations(severe) brain fog,shakiness and exhaustion. Its been about a month since I quit cold turkey and side effects are still noticeable but not as severe. Please seek an alternative for your condition and best wishes

      Ofcourse it does It rescued my life for numerous times, I had internal bleeding ulcer, bleeding, erosive gastritis, erosive esophagitis and the PPI worked like a magic pill, after 6 weeks my stomach lining looked completely healthy. I'm still using it, eating what I want, drinking what I want..
