Common Reactions to Quasense
Common Side Effects
Quasense has been thoroughly studied 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 compared to the side effects that occur in another group of people not taking the medicine. (These people 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.
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 side effects of Quasense. In fact, the side effects listed in the prescribing information for the drug are actually side effects of all birth control pills in general, not necessarily just Quasense.
Some of the common side effects of birth control pills include but are not limited to:
- Breast tenderness and enlargement
- Breakthrough bleeding and spotting between periods
- Nausea and vomiting
- Changes in your eyes that make it more difficult to wear contact lenses
- 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 Seasonale and Weight Gain).
You may experience some or none of the side effects of Quasense listed in this article. Unfortunately, it can be difficult to tell whether any particular side effect (such as nausea) is caused by Quasense or other factors.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking the drug or if something "just does not seem right." While it may not be a side effect of Quasense, your healthcare provider will be able to diagnose and treat the problem.
