Xalkori Side Effects
Vision problems, nausea, and constipation are some of the most commonly reported side effects that occurred during clinical studies on Xalkori. While reactions such as these tend to be minor, there are some potentially serious problems that need to be treated. Notify your healthcare provider immediately if you are taking Xalkori and develop side effects such as fever, dark urine, or vision problems.
An Introduction to Xalkori Side EffectsJust like any medicine, Xalkori® (crizotinib) 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 Xalkori. Your healthcare provider can discuss a more complete list with you.)
