An Introduction to Metadate ER Side Effects

As with any medicine, side effects are possible with Metadate ER^® (methylphenidate extended-release). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.

(The Metadate ER side effects discussed below are not a complete list of reported side effects. Your healthcare provider can discuss a more complete list with you.)

Common Metadate ER Side Effects

Metadate ER has been studied thoroughly in clinical trials, in which the side effects of a group of people taking the drug are documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.

Based on these studies, the most common side effects of Metadate ER include:

Nervousness
Insomnia
Loss of appetite
Nausea
Dizziness
Headache
Drowsiness
Abdominal pain (stomach pain)
Weight loss (see Metadate and Weight Loss).

Metadate ER can also cause a temporary slowing down of growth in children. This is usually small (less than an inch and less than two pounds), and children usually catch up to normal growth rates with time.
