Androgens (AN-droe-jens) are male hormones. Some androgens are naturally produced in the body and are necessary for the normal sexual development of males.

Androgens are used for several reasons, such as:

In addition, some of these medicines may be used for other conditions as determined by your doctor.

Androgens are available only with your doctor's prescription, in the following dosage forms:

Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For androgens, the following should be considered:


Tell your doctor if you have ever had any unusual or allergic reaction to androgens. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.


Androgens are not recommended during pregnancy. When given to pregnant women, the medicine has caused male features to develop in female babies.


Use is not recommended in nursing mothers, since androgens may pass into the breast milk and may cause unwanted effects in the nursing baby, such as premature (too early) sexual development in males and development of male features in female babies.


Androgens may cause children to stop growing. In addition, androgens may make male children develop too fast sexually and may cause male-like changes in female children.

Older adults

When older male patients are treated with androgens, they may have an increased risk of enlarged prostate (a male gland) or their existing prostate cancer may get worse. For these reasons, a prostate examination and a blood test to check for prostate cancer is often done before androgens are prescribed for men over 50 years of age. These examinations may be repeated during treatment.

Other medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking androgens, it is especially important that your health care professional know if you are taking any of the following:
