Covaryx (Oral)

Esterified estrogens and methyltestosterone combination is used to treat menopause symptoms in patients who did not find relief from estrogens alone. These symptoms may include hot flashes, which are feelings of heat, sweating, and warmth in the face, neck, or chest, and vaginal dryness, burning, and itching.

Esterified estrogens are a synthetic mix of estrogens. Estrogen is a hormone that the body produces more of in females. It is essential for normal sexual development in females and for regulating the menstrual cycle during childbearing years. Methyltestosterone is a synthetic form of testosterone, a hormone that the body produces more of in males and in smaller amounts in females. Menopause symptoms arise when the hormone balance in the female body changes. This combination of hormones helps relieve menopause symptoms by increasing hormone levels in the body.

This medicine is available only with your doctor's prescription.

It is very important for your doctor to check your progress during regular visits to ensure that the medicine is working properly and to decide if you should keep taking it. These visits should be every 6 to 12 months or as directed by your doctor.

It is unlikely that a postmenopausal woman may become pregnant. However, using this medicine while you are pregnant could harm your unborn baby. If you think you have become pregnant while using the medicine, tell your doctor immediately.

Very rarely, this medicine can cause serious side effects like a heart attack or stroke. You are much more likely to experience these side effects if you smoke cigarettes, are overweight, or have diabetes, high blood pressure, or high blood cholesterol. Talk to your doctor if you think you might be at risk.

Using large doses of estrogen alone for a long time may increase the risk of certain types of cancer (e.g., endometrial cancer). Discuss this risk with your doctor. If you experience vaginal bleeding while using this medicine, contact your doctor right away.

This medicine may increase the risk of developing breast cancer. It is very important to regularly check your breasts for any unusual lumps or discharge, and to have breast x-rays every year as directed by your doctor. These exams are especially important if you have a family member with a history of breast cancer. Talk to your doctor about this risk.

This medicine may increase the risk of developing dementia in elderly women (over 65 years of age). Discuss this concern with your doctor.

Contact your doctor immediately if you experience blurred vision, difficulty reading, or any other changes in vision during or after treatment. Your doctor may want you to have an eye exam by an ophthalmologist.

Using large doses of methyltestosterone for a long time may increase the risk of serious liver problems (e.g., peliosis hepatis or liver cancer). Discuss this risk with your doctor.

Before undergoing any medical tests, inform the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine. You may also need to stop using this medicine for a few weeks before and after surgery, or if you are inactive for an extended period.

Do not take other medicines unless your doctor has discussed them with you. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
