Quillivant XR Side Effects
Insomnia, mood swings, and decreased appetite are a few common side effects of Quillivant XR. Some other possible reactions include nausea, irritability, and blurry vision. Some side effects that you should report to your healthcare provider immediately include depression, suicidal thoughts, and uncontrollable repetitive movements. These reactions are potentially serious and require prompt medical attention.
As with any medicine, Quillivant XR™ (methylphenidate ER oral suspension) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Quillivant XR. Your healthcare provider can discuss a more complete list with you.)
Quillivant XR has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking Quillivant XR were carefully documented and compared with the side effects that occurred in a similar group taking a placebo (a "medicine" containing no active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
In clinical studies, the most common Quillivant XR side effects included:
- Mood swings -- in up to 9 percent of people
- Scratches or scrapes to the skin -- up to 4 percent
- Insomnia (especially in the beginning of treatment) -- up to 2 percent
- Decreased appetite -- up to 2 percent
- Vomiting -- up to 2 percent
- Tics (sudden, repetitive movements that are difficult to control) -- up to 2 percent
- Motion sickness -- up to 2 percent
- Eye pain -- up to 2 percent
- Rash -- up to 2 percent.
Based on clinical studies of other medicines containing methylphenidate (the active drug in Quillivant XR), other possible side effects may include:
