Side Effects of Junel

Changes in sex drive, breast tenderness, and headaches are some of the common side effects of birth control pills (such as Junel). Side effects can be bothersome, but are generally not dangerous. However, there are some potentially serious side effects of Junel that should be reported to a healthcare provider right away, including breast lumps, chest pain, or sudden loss of vision.

An Introduction to Side Effects of Junel

As with any medicine, side effects are possible with Junel™ (norethindrone/ethinyl estradiol); however, not all women who use the drug will experience side effects. In fact, most women tolerate it quite well. If 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. Often, many of the bothersome Junel side effects improve (or even completely go away) within the first few cycles of use.
(This article covers many, but not all, of the possible side effects with Junel. Your healthcare provider can discuss a more complete list of Junel side effects with you. Junel is a generic version of Loestrin®.)
