Common Side Effects
In 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 adverse reactions 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 whether they are actual side effects of the medication. 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 Emoquette side effects. In fact, the side effects listed in the prescribing information are actually the possible side effects of all birth control pills in general, not necessarily just of Emoquette.
Some of the common, bothersome (but not usually dangerous) reactions to birth control pills include:
- Breakthrough bleeding and spotting between periods, especially for the first few cycles
- Nausea and vomiting
- Changes in your eyes that make it more difficult to wear contact lenses
- Breast tenderness and enlargement
- Headaches (birth control pills can improve headaches in some women)
- Acne (birth control pills can also improve acne)
- Changes in sex drive, often a decrease.
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 Desogen and Weight Gain).
