Common Side Effects of KarivaIn clinical studies for most medications, one group of people receives the actual medication, while another group is given a placebo (a "sugar pill" that does not contain any active ingredients). The side effects in both groups are carefully documented and compared. 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 side effects from studies that do not use a placebo, only vague information is available about Kariva side effects. In fact, the side effects listed in the prescribing information of Kariva are actually the potential side effects of all birth control pills in general (not necessarily just of Kariva). Some of the common side effects of birth control pills include, but are not limited to:
- Nausea and vomiting
- Changes in your eyes that make it more difficult to wear contact lenses
- Breast tenderness and enlargement
- Breakthrough bleeding and spotting (between periods)
- Acne (although birth control pills can also improve acne)
- Changes in sex drive.
Women are often concerned about weight gain due to birth control pills, but recent research suggests that birth control pills probably do not cause weight gain for most women (see Mircette and Weight Gain).
