CombiPatch (estradiol, norethindrone acetate transdermal system) is used to treat the symptoms of menopause such as feelings of warmth in the face, neck and chest, or sudden intense spells of heat and sweating ("hot flashes" or "hot flushes"); to treat vulvar and vaginal changes (itching, burning, dryness in or around the vagina, difficulty or burning with urination) caused by menopause; and to replace estrogen in conditions such as hypogonadism, removal of the ovaries, or primary ovarian failure that result in a lack of estrogen. It is a combination of female hormones. Common side effects include skin redness/irritation at the application site, abdominal pain, nausea/vomiting, bloating, breast tenderness, headache, or weight changes.

Two CombiPatch transdermal delivery systems are available: 0.05 mg estradiol with 0.14 mg NETA per day (9 sq cm) and 0.05 mg estradiol with 0.25 mg NETA per day (16 sq cm). The lowest effective dose should be used. CombiPatch may interact with anticoagulants (blood thinners). Tell your doctor all medications you use. CombiPatch must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor. This medication passes into breast milk. It may reduce the quality and amount of breast milk produced. Consult your doctor before breast-feeding.

Our CombiPatch (estradiol, norethindrone acetate transdermal system) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is Patient Information in Detail?

Easy-to-read and understand detailed drug information and pill images for the patient or caregiver from Cerner Multum.

CombiPatch in Detail - Patient Information: Side Effects

Treatment with estrogens long-term may increase the risk of heart attack, stroke, breast cancer, and blood clots in the lungs or legs. Because of these risks, you should contact your doctor or healthcare provider to discuss your individual risks and benefits before using estradiol and norethindrone long-term. You should also talk to your doctor or healthcare provider on a regular basis (for example, every 3-6 months) about whether you should continue this treatment.

If you experience any of the following serious side effects, stop using estradiol and norethindrone and seek emergency medical attention or notify your doctor immediately:

  • an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);
  • sharp chest pain, coughing of blood or shortness of breath (possible blood clot in the lung );
  • pain in the calf (possible blood clot in the leg);
  • crushing chest pain or heaviness in the chest (possible heart attack);
  • sudden severe headache or vomiting, dizziness or fainting, disturbances of vision or speech, weakness, or numbness in an arm or leg (possible stroke);
  • partial or complete loss of vision (possible clot in the eye);
  • stomach pain or tenderness, yellowing of the skin or eyes, fever, fatigue, loss of appetite, dark-colored urine, or light-colored stools (possible liver problems); or
  • new or changing breast lumps.

Other, less serious side effects may be more likely to occur. Continue to use estradiol and norethindrone and talk to your doctor if you experience

  • nausea and vomiting;
  • tenderness or enlargement of the breasts;
  • weakness;
  • swelling of the hands or feet;
  • spotty darkening of the skin, particularly on the face;
  • difficulty in wearing contact lenses;
  • vaginal irritation or discomfort;
  • a rash or reaction at the patch application site; or
  • changes in menstrual cycle, painful menstruation, or breakthrough bleeding.

Estradiol increases the risk of developing endometrial hyperplasia, a condition that may lead to cancer of the lining of the uterus. Using a progestin, such as norethindrone, with estradiol lowers the risk of developing this condition. Visit your doctor regularly and report any unusual vaginal bleeding right away.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.

(Adverse Reactions)

SIDE EFFECTS

See BOXED WARNINGS, WARNINGS and PRECAUTIONS.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.
