An Introduction to Beyaz Side Effects
As with any medicine, side effects are possible with Beyaz
™ (drospirenone/ethinyl estradiol/levomefolate calcium
). However, not everyone who uses the contraceptive will experience problems. In fact, most women tolerate it 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 side effects with Beyaz. Your healthcare provider can discuss a more complete list with you.)
Common Side Effects of Beyaz
Beyaz was approved based on clinical studies of Yaz®
(the exact same birth control pill
without the folate). Yaz has been studied thoroughly in clinical trials.
In most clinical studies of medications, the side effects that occur in a group of people taking the drug are documented and then compared to those that occur in another group of people not taking the medicine (they take a placebo that does not contain any 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.
In these studies, common side effects (occurring in more than 1 percent of women) included but were not limited to:
- Breakthrough bleeding or spotting (bleeding between periods) or other menstrual irregularities -- in up to 24.9 percent of women
- Nausea -- up to 15.8 percent
- Headache -- up to 13 percent
- Breast tenderness -- up to 10.5 percent
- Fatigue -- up to 4.2 percent
- Irritability -- up to 2.8 percent
- Decreased sex drive -- up to 2.8 percent
- Weight gain -- up to 2.5 percent (see Yaz and Weight Gain)
- Mood swings -- up to 1.2 percent.
