I am 23 year old female, been on toprol xl 50 mg for almost 7 months and i have gained aleast 15 pounds, i have very bad hot flashes where my upper body gets extremely hot and i sweat, my heart beats rapidly on occassions also i have found it almost impossible to lose the pounds i have gained...my doc says toprol dosn't make you gain weight, but how would he know, he isn't on it...can anybody relate?
