I just starting taking nexium 40m and since Sunday I loos of appetite and I don't liked at all I?

Actually, its not a side-effect of the drug but a side-effect of having lower than normal stomach acids. Since Nexium reduces your stomach acid levels, if the dose is to high or your acid/GERD is mild, it may indirectly cause a loss of appetite.

If you are taking the drug short term - a week or two - I wouldn't worry about it. If its a long term treatment check with your doc to make sure the dose isn't too high.

Hi there, I take Nexium 40mg too. It never took my appetite away. I agree with maso4169 and caringsonbj. You should contact your doctor. It sounds like it could be something else you are taking of are you feeling a little depressed? Keep in touch and let us know how it goes. Take care.

in the past I have had a lot of gastrointestional surgery, afterwards I had problems that made it necessary to prescribe Nexium I have looked the side effects up neither did I find this particular one nor did I experience this loss of appetite, please talk with you prescribing physician or your gastroenerologist just to be on the safe side

I also take nexium 40mg. and have not experienced what you have.

I checked and loss of appetite as such is not listed as a side effect as a matter of fact under "Side effects by body system" under Gastrointestinal possible side effects are increased appetite and anorexia, which is very contradicting.

I strongly suggest you contact your Dr. right away and inform him / her what you are experiencing.

I hope you get well soon.

All the best and take care.
