"I have been taking daytrana since 2010 it works great but now I have partial heart failure and pulmonary hypertension. I didn't abuse the patch I took one 30mg patch a day! I'm 35 and now it doesn't work like it use to because of one side effect that it gave me so yes use with caution and don't use it everyday if you don't have to!"
