Common Lamotrigine Side Effects
Lamotrigine has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people 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.
In these studies, the most common side effects of lamotrigine included:
- Dizziness -- in up to 54 percent of people
- Double vision -- up to 49 percent
- Headaches -- up to 29 percent
- Coordination problems -- up to 28 percent
- Blurred vision -- up to 25 percent
- Nausea -- up to 25 percent
- Vomiting -- up to 20 percent.
