Conjugated estrogens / methyltestosterone Side Effects
Applies to conjugated estrogens / methyltestosterone: oral tablet.
Conjugated estrogens increase the risk of developing a condition (endometrial hyperplasia) that may lead to cancer of the lining of the uterus. Taking progestins, another hormone drug, with conjugated estrogens may lower the risk of developing this condition. Therefore, if your uterus has not been removed, your doctor may prescribe a progestin for you to take together with the estrogen. Visit your doctor regularly and report any unusual vaginal bleeding right away.
Have yearly physical exams and examine your breasts for lumps on a monthly basis.
Notify your doctor if you experience vomiting, swelling of the arms or legs, hoarseness, deepening of the voice, male-pattern baldness, excessive hair growth, clitoral enlargement, or yellowing of the skin or eyes.
Do not take conjugated estrogens and methyltestosterone if you are pregnant.
If you experience any of the following serious side effects, stop taking conjugated estrogens and methyltestosterone 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);
-
a blood clot (pain, redness, and swelling in an arm or leg; shortness of breath; chest pain; headache; blurred vision; or confusion);
-
a lump in a breast;
-
liver damage (yellowing of the skin or eyes, nausea, abdominal pain or discomfort, unusual bleeding or bruising, severe fatigue); or
-
hoarseness, deepening of the voice, male-pattern baldness, excessive hair growth, or clitoral enlargement (these changes may be irreversible).
