This medication can rarely cause a certain serious lung problem (pulmonary oil microembolism-POME), caused by tiny droplets of oil that have traveled to the lungs. Symptoms may include cough/urge to cough, difficulty breathing, sweating, tightening of the throat, chest pain, dizziness, or fainting. Most of the time, symptoms last only a few minutes and improve with medical help. However, symptoms have sometimes lasted up to several hours, or worsened and required treatment in a hospital. Serious (rarely fatal) allergic reactions may also occur. These side effects may happen during or right after each injection. To be sure that you do not have a serious reaction, you will need to stay in a health care setting for 30 minutes after each injection so your doctor can carefully monitor you and provide medical help if needed.
To receive testosterone undecanoate injection in the United States, you must understand, agree to, and carefully follow the requirements of the REMS Program for this medication. If you live in Canada or any other country, consult your doctor and pharmacist for your country's regulations.
This medication is used in men who do not make enough of a natural substance called testosterone. Testosterone belongs to a class of drugs known as androgens. Testosterone helps the body to develop and maintain male sexual characteristics (masculinity), such as a deep voice and body hair. It also helps to maintain muscle and prevent bone loss, and is necessary for natural sexual ability/desire.
Testosterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty.
This product should not be used in women.
