I took it for a short period of time but it was changed over to invega sustenna which is a related med, an active metabolyte of risperidone. Since they're very similar what I experienced was a large amount of weight gain and it stopped my period. It was pretty helpful for several years but I had to get off it eventually for a few different reasons, mainly the weight gain and the begining of tardive dyskinesia, but I was on the max dose of the injection and got it at every 3 weeks instead of 4, so that may be why I had more problems.
