ADHD Home > Ritalin Weight Change
Ritalin® (methylphenidate hydrochloride) is a medication used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD). As with any medicine, side effects are possible with Ritalin, and changes in weight were reported in clinical trials.
Specifically, these clinical studies showed that Ritalin commonly caused weight loss. Although weight loss may be a desirable side effect for some children and teens, too much weight loss can be a problem for growing bodies.
In some cases, waiting until after breakfast to take Ritalin may help with loss of appetite and/or weight loss. If your child or teenager seems to be losing too much weight, talk to your healthcare provider. There are other ADHD medications that may not cause these problems for your child.
On occasion, healthcare providers may prescribe Ritalin as a weight loss medicine, but this is not an approved use.
