An Introduction to Lybrel Side Effects
As with any medicine, side effects are possible with Lybrel
™ (levonorgestrel/ethinyl estradiol). However, not everyone who uses the contraceptive 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.
(This article covers many, but not all, of the possible side effects with Lybrel. Your healthcare provider can discuss a more complete list of side effects with you.)
Common Side Effects of Lybrel
Lybrel has been studied thoroughly in clinical trials. In the studies for most medications, the side effects that occur in a group of people taking the drug are documented and then compared to the side effects that occur in another group of people not taking the medicine (who take a placebo that does not contain active ingredients). As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine. However, it is not possible to use a placebo in clinical trials for contraceptives, as this would lead to many unintentional pregnancies.
Because it is difficult to obtain much information about possible side effects from studies that do not use a placebo, only vague information is available about potential Lybrel side effects. In fact, the side effects listed in the prescribing information of Lybrel are actually the possible side effects of all birth control pills
in general (not necessarily just of Lybrel). Some of the common side effects of birth control pills
include, but are not limited to:
- Breast tenderness and enlargement
- Changes in your eyes that make it more difficult to wear contact lenses
- Headaches (although sometimes birth control pills improve headaches)
- Nausea and vomiting
- Acne (although many women find that birth control pills actually improve acne)
- Changes in sex drive.
