Possible reactions to Gilenya include headaches, diarrhea, and back pain. In most cases, people can take this medication without any problems.

An Introduction to Gilenya Side Effects

Just like any medicine, Gilenya™ (fingolimod) 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.

Common Side Effects of Gilenya

Gilenya has been studied extensively in clinical trials. In these studies, one group of people received the real medication, while another group was given a placebo (a "sugar pill" that does not contain any 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 these studies, the most common side effects of Gilenya included:
  • A headache -- in up to 25 percent of people
  • Increased liver enzymes (seen on a blood test) -- up to 14 percent
  • The flu -- up to 13 percent
  • Diarrhea -- up to 12 percent
  • Back pain -- up to 12 percent
  • Coughing -- up to 10 percent.
Other common side effects (occurring in 3 to 9 percent of people) included:
