This site makes for very interesting reading, I guess anyone who's got this far will now have an idea that Omeprazole whilst being an effective treatment for some gastric problems can have some quite severe side effects.
I was prescribed this drug after a stomach bleed (caused by use of NSAIDs for back pain) and whilst it seemed to help clear up the condition the side effects have been quite severe.
Around January i was put on this medication and experienced fatigue, muscle cramps,swollen legs and dizziness for the two months i was on it, it wasn't until i had a recurrence of the bleeding in May and started to take Omeprazole again that I noticed that the side effects had returned, feeling pretty crappy i went back to the doctor and was told to double up the dose, this made me feel twice as bad, heart palpitations, dizziness, constant fatigue, muscle cramps and kind of anxious and depressed (although i put these last two symptoms down to my inability to get to grips with my bad physical health)
After reading the comments posted here I haven't take Omeprazole for four days now and already the symptoms have all but disappeared, I feel as if a weight has been lifted off my body and my mind, my energy is starting to return and I am sure that I have spent the last month suffering because of this drug. If i have a recurrence of the original condition i will seek alternative treatment, Omeprazole made my tummy better but at too high a price for me to ever consider taking it again.
