While taking naproxen I have gained 15 lbs. Will stopping cause weight loss?

If you feel this is the cause of weight gain and you havent changed nothing in your diet and this is all you take this could be possibly the reason. There is something that changed in your life to cause this weight gain it may just be stress and you havent noticed youve been eating more.

Several side effects are possible with naproxen. Weight gain, however, does not appear to be one of them. This data comes from clinical trials where the drug was studied extensively and side effects were carefully documented.

It is a serious side effect which must de reported to your Doctor.

Fluid retention or unexplained weight gain.

I suggest you talk to your doctor and ask him-her to derive you to a nutrisionist to get you on the right diet. Also excersice helps, a lot.

Take care
