Quartette Side Effects

Migraines, mood changes, and headaches are some of the common side effects reported with Quartette. Such problems are merely bothersome in most cases and are usually not dangerous. However, some reactions could be potentially serious and should be reported to a healthcare provider immediately, including coughing up blood, a severe headache, and depression.

An Introduction to Quartette Side Effects

Just like any medicine, Quartette™ (levonorgestrel/ethinyl estradiol) can cause side effects. However, not all women who use this contraceptive will experience problems. In fact, most women tolerate it quite well. If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Quartette. Your healthcare provider can discuss a more complete list with you.)

Common Side Effects of Quartette

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 side effects in both groups are carefully documented and compared. As a result, it is possible to see what reactions occur, how often they appear, and whether they are actual side effects of the medication. However, it is unethical 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 potential Quartette side effects. In fact, the side effects listed in the prescribing information for this product are actually possible with all birth control pills in general.
Some of the common bothersome, but not usually dangerous, reactions to birth control pills include:
  • Headaches -- in up to 12.2 percent of women
  • Heavy or irregular vaginal bleeding -- up to 9.7 percent
  • Nausea or vomiting -- up to 8.8 percent
  • Acne -- up to 5.4 percent
  • Painful menstrual periods -- up to 5.4 percent
