Mircette Warnings and Precautions

Specific Precautions and Warnings for Mircette

Some of the warnings and precautions to be aware of prior to using Mircette include the following:
  • Combined oral contraceptives (including Mircette) increase the risk of blood clots, strokes, and heart attacks. These risks are minimal for healthy, young nonsmokers. Make sure to tell your healthcare provider if you have ever had a blood clot, stroke, heart attack, or chest pain. Smoking cigarettes greatly increases the risk of serious Mircette side effects (such as heart attacks, strokes, and blood clots). This risk is particularly high for smokers over the age of 35.
  • Mircette does not protect against HIV, AIDS, or other sexually transmitted diseases (STDs). In many cases, it is advisable to use condoms in addition to Mircette.
  • Mircette can interact with a number of different medications (see Mircette Drug Interactions for more information).
  • Combined oral contraceptives may also slightly increase the risk of breast cancer or cervical cancer, although this is an unresolved and controversial issue. However, combined oral contraceptives seem to help protect women against ovarian and uterine cancer.
  • Birth control pills are sometimes not the best contraceptive choice for obese women. The pills may be less effective in these women, and obese women may be at a higher risk for developing serious Mircette side effects.
  • Oral contraceptives increase the risk of benign (non-cancerous) liver tumors. Very rarely, these tumors can rupture and cause serious problems.
  • Hormonal contraceptives (such as Mircette) can make gallbladder disease worse. If you have had a problem with your gallbladder, Mircette may not be the best contraceptive method for you.
  • Mircette may increase blood sugar levels, particularly in women with diabetes. Your healthcare provider may need to monitor you more closely. Let your healthcare provider know if you have any sudden vision changes, as this may be a sign of a blood clot in the eyes (a possible side effect of Mircette and other hormonal contraceptives).
  • Hormonal contraceptives (including Mircette) can increase your blood pressure. This can be a problem if you already have high blood pressure.
  • If you experience a migraine for the first time (or have any changes in your migraines if you have had them before) while taking Mircette, please contact your healthcare provider.
  • Mircette can change your menstrual bleeding patterns. Some women have breakthrough bleeding (bleeding between periods), while others may not have a period at all. It is normal to have shorter and lighter periods while using Mircette. If you notice any unusual changes in your bleeding patterns, let your healthcare provider know. If you miss a period, you should make sure you are not pregnant.
  • Mircette can affect your cholesterol. Your healthcare provider may need to check your cholesterol levels after you start Mircette, especially if you already have high cholesterol.
  • Sometimes, hormonal contraceptives can make depression worse. Let your healthcare provider know if you develop new or worsening depression symptoms.
  • Occasionally, Mircette (as well as any other hormonal contraceptive) can cause eye changes that make it more difficult to wear contact lenses.
  • Mircette is considered a pregnancy Category X medication. This means that you should not use Mircette during pregnancy (see Mircette and Pregnancy).
  • Contraceptive hormones (such as the ones in Mircette) do pass through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the contraceptive (see Mircette and Breastfeeding). Combined hormonal contraceptives (such as Mircette) are not usually recommended for breastfeeding women.
