STD Home > Caziant Side Effects

While most women who take birth control pills do not experience problems, adverse reactions are possible. For example, common Caziant side effects could include spotting between periods, nausea, and breast tenderness. Fortunately, such problems are usually mild and easily treated. Serious side effects, however, require medical attention. These include sudden vision changes, signs of a stroke, and signs of liver damage.

An Introduction to Side Effects of Caziant

As with any medicine, side effects are possible with Caziant™ (desogestrel/ethinyl estradiol); however, not every woman who uses the contraceptive will experience problems. 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 be treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible Caziant side effects. Your healthcare provider can discuss a more complete list with you. Caziant is a generic version of the brand-name birth control pill Cyclessa®.)

Birth Control Pills and Clinical Trials

In the United States, medications must be shown to be safe and effective in clinical studies before they are approved. In 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). Typically, the subjects do not know 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 if 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.
