I sustained a concussion in August 2016. My Neurologist prescribed me cyproheptadine. I have been taking it for 2 months. I noticed I have gained 40 pounds since I have been on the medication. I know the medication is also used if people are suffering from anorexia. I want to go off it. Will I lose the weight if I stop taking cyproheptadine? Also, can I quit cyproheptadine cold turkey?
