How is Luvox CR different from Luvox?

Luvox CR contains the same active ingredient, fluvoxamine, as Luvox but in an "extended release" capsule that is formulated to dissolve slowly, giving a steady dose of the drug throughout the day. In contrast, Luvox is available as an immediate-release tablet.

Luvox CR is available in 100 milligram (mg) and 150 mg capsules. There are no generic versions of Luvox CR on the market. Luvox is available as an oral tablet in 25 mg, 50 mg and 100 mg as both brand-name and generic products.

Luvox is approved by the Food and Drug Administration (FDA) for treating obsessive-compulsive disorder (OCD) in adults and children ages 8 to 17. Luvox CR has been studied in adults and is recommended for treating adults with OCD, beginning with a starting dose of 100 mg taken at bedtime, compared to a recommended starting dose for adults of 50 mg for Luvox. Luvox CR has not been adequately studied in children, and its safety and effectiveness in children has not been proven.

Both Luvox and Luvox CR may cause side effects, including potentially serious or life-threatening ones, especially when taken by people who have certain medical conditions or who take certain other drugs or supplements. Before taking either Luvox and Luvox CR, give your doctor a detailed medical history and a list of all medicines (prescription and nonprescription), supplements and herbal remedies that you take to reduce your risk of dangerous interactions.
