Side Effects of Introvale

Commonly reported side effects of birth control pills (including Introvale) include nausea, headaches, and breast tenderness. Fortunately, if such problems occur, they are usually mild and easily treated. If you experience difficulty breathing, unexplained wheezing, heavy vaginal bleeding, or any other potentially serious problems while taking this oral contraceptive, contact your healthcare provider right away.

An Introduction to Introvale Side Effects

Introvale™ (levonorgestrel/ethinyl estradiol) is a prescription birth control pill (oral contraceptive). Because it is a generic version of Seasonale®, any side effect information for Seasonale also applies to Introvale.
 
As with any medicine, side effects are possible with Introvale. However, not everyone who uses the oral contraceptive will experience 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 Introvale side effects. Your healthcare provider can discuss a more complete list with you.)
