Anxiety Home > Luvox CR Side Effects

Nausea, headaches, and insomnia are the most common side effects reported with Luvox CR. Side effects that have also been seen in 1 to 10 percent of people taking the drug include indigestion or heartburn, twitching, and weight loss. Some side effects of Luvox CR are potentially serious and require immediate medical attention, including suicidal thoughts or behavior, chest pain, or hallucinations.

An Introduction to Luvox CR Side Effects

As with any medicine, side effects are possible with Luvox® CR (fluvoxamine CR). However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If Luvox CR side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Luvox CR. Your healthcare provider can discuss a more complete list of Luvox CR side effects with you.)
