Side Effects of Fingolimod
Although most people do not experience problems while using fingolimod, side effects are possible. Common ones include headaches, diarrhea, and back pain. Serious problems have also been known to occur with this medication. Notify your healthcare provider right away if you experience difficulty breathing, fainting, fever, or other potentially dangerous side effects.
Just like any medicine, fingolimod (Gilenya™) 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.
