Description

Androgens (AN-droe-jens) are male hormones. Someandrogens are naturally produced in the body and are necessary for the normalsexual development of males.

Androgens are used for several reasons, such as:

  • to replace the hormone when the body is unable to produce enoughon its own.
  • to stimulate the beginning of puberty in certain boys who are latestarting puberty naturally.
  • to treat certain types of breast cancer in females.

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

Before Using This Medicine

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

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

Pregnancy?Androgens are not recommended during pregnancy. Whengiven to pregnant women, the medicine has caused male features to developin female babies.

Breast-feeding?Use is not recommended in nursing mothers, sinceandrogens may pass into the breast milk and may cause unwanted effects inthe nursing baby, such as premature (too early) sexual development in malesand development of male features in female babies.

Children?Androgens may cause children to stop growing. Inaddition, androgens may make male children develop too fast sexually and maycause 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 theirexisting prostate cancer may get worse. For these reasons, a prostate examinationand a blood test to check for prostate cancer is often done before androgensare prescribed for men over 50 years of age. These examinations may be repeatedduring treatment.

Other medicines?Although certain medicines should not be usedtogether at all, in other cases two different medicines may be used togethereven if an interaction might occur. In these cases, your doctor may want tochange the dose, or other precautions may be necessary. When you are takingandrogens, it is especially important that your health care professional knowif you are taking any of the following:

  • Acetaminophen (e.g., Tylenol) (with long-term, high-dose use) or
  • Amiodarone (e.g., Cordarone) or

  • Anticoagulants (blood thinners)?Androgens can increase theeffect of these medicines and possibly cause excessive bleeding

Other medical problems?The presence of other medicalproblems may affect the use of androgens. Make sure you tell your doctor ifyou have any other medical problems, especially:

  • Breast cancer (in males) or
  • Prostate cancer?Androgens can cause growth of these tumors

  • Diabetes mellitus (sugar diabetes)?Androgens can increase ordecrease blood sugar levels. Careful monitoring of blood glucose should bedone
  • Edema (swelling of face, hands, feet, or lower legs) or
  • Kidney disease or
  • Liver disease?These conditions can be worsened by the fluidretention (keeping too much water in the body) that can be caused by androgens.Also, liver disease can prevent the body from removing the medicine from thebloodstream as fast as it normally would. This could increase the chance ofside effects occurring
  • Enlarged prostate?Androgens can cause further enlargement ofthe prostate
  • Heart or blood vessel disease?Androgens can make these conditionsworse because androgens may increase blood cholesterol levels. Also, androgenscan cause fluid retention (keeping too much water in the body), which alsocan worsen heart or blood vessel disease

Side Effects of This Medicine

Discuss these possible effects with your doctor:

  • Tumors of the liver, liver cancer, or peliosis hepatis (a form ofliver 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 alreadyhave it but have not yet been diagnosed. Also, the prostate (a male gland)may become enlarged. Enlargement of the prostate does not mean that cancerwill 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-likechanges may occur, such as hoarseness or deepening of the voice, unnaturalhair growth, or unusual hair loss. Most of these changes will go away if themedicine 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 withthe production of sperm. This effect is usually temporary and only happensduring the time you are taking the medicine. However, discuss this possibleeffect with your doctor if you are planning on having children.
