Common Side Effects
Yaz® (the brand-name version of Gianvi) 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, commonly reported side effects (occurring in more than 1 percent of women) included but were not limited to:
- A decreased sex drive
- An increased appetite
- Breakthrough bleeding or spotting (bleeding between periods)
- Vaginal discharge
- Vaginal yeast infections
- Nausea and vomiting
- Weight gain (see Yaz and Weight Gain).
Final ThoughtsYou may experience some or none of the Gianvi side effects listed in this article. Unfortunately, it can be difficult to tell whether any particular side effect (such as nausea) is caused by Gianvi or other factors.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking this oral contraceptive or if something "just does not seem right." While it may not be related to Gianvi, your healthcare provider will be able to diagnose and treat the problem.
