MonoNessa Side Effects
Breast tenderness, breakthrough bleeding, nausea, and bloating are some of the side effects that may occur with MonoNessa. Side effects can be bothersome but are usually not dangerous. However, there are a number of potentially serious side effects of MonoNessa that should be reported to a healthcare provider immediately, including heavy vaginal bleeding between periods, high blood pressure, or any signs of an allergic reaction.
As with any medicine, side effects are possible with MonoNessa® (norgestimate/ethinyl estradiol); however, not every woman who uses the contraceptive will experience side effects. In fact, most women tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with MonoNessa. Your healthcare provider can discuss a more complete list of MonoNessa side effects with you. MonoNessa is a generic version of Ortho-Cyclen®.)
Before medications are approved in the United States, they must undergo several clinical studies to show that they are both safe and effective. In the clinical studies for most medications, one group of people is given the actual medication, while another group is given a placebo (a "sugar pill" with no active ingredients). The people are not told if they are taking the real medication or the placebo.
The side effects in both groups are carefully documented and compared. This way, 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 usually possible to use a placebo in clinical trials for contraceptives, as this would lead to many unintentional pregnancies.
