How to prevent weight gain while on Resperidone (resperdal)?

I too, stuggled with anorexia in my late 20,s and I looked fine. I even tried a high dose of prescription weight loss pills after the pregnancy a couple of yr.s ago, and couldn't lose any. So I understand how you feel about losing the weight and not wanting to gain it back. But I also understand needing the medication for mental health problems. Espesially if your state of mind is out of control. It may not do this for everyone, because everyone is different, and sometimes people have to try different meds until they find one that works for them. In my opinion. risperidone did make me gain a few pounds so I talked to my psych doctor and told him I absolute couldn't gain more weight, due to my back. But I will make it clear that it may not do that to everybody. He changed it to a newer medication, that he quote said..Was more prone to not gain weight, which is called Invega. It's expensive, but if you talk to your doctor, most of them have voucher cards for it so you don't have to pay as much. So far, my weight has remained the same. I'm certainly not telling you to stop what you are on and take the one I am on. I'm saying to talk to your doctor, as kaismama said, and have a very strong conversation with him about the situation, and I would weigh myself too, or you won't know if you've gained weiht or not. I wish you the very best of luck, and hope you find a good outcome no matter what it is. Sometimes it can be a catch 22. And soo frusturating. But you don't need to take nothing if you mentally need it. A few pounds is better than an awful mental state. Believe me on that one. May you have a great weekend and bless you. Take care, Ruthie
