Interactions with Medications
Discuss these possible effects with your doctor:
Tumors of the liver, liver cancer, or peliosis hepatis (a form of liver disease) have occurred during long-term, high-dose therapy with androgens. Although these effects are rare, they can be very serious and may cause death.
Androgens can stimulate existing prostate cancer in men who already have it but have not yet been diagnosed. Also, the prostate (a male gland) may become enlarged. Enlargement of the prostate does not mean that cancer will develop. If enlargement occurs and you have difficulty in urinating, it is a good idea to be checked by your doctor.
When androgens are used in women, especially in high doses, male-like changes may occur, such as hoarseness or deepening of the voice, unnatural hair growth, or unusual hair loss. Most of these changes will go away if the medicine is stopped as soon as the changes are noticed. However, some changes, such as voice changes or enlarged clitoris, may not go away.
When androgens are used in high doses in males, they interfere with the production of sperm. This effect is usually temporary and only happens during the time you are taking the medicine. However, discuss this possible effect with your doctor if you are planning on having children.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
