What is Aveed?

Aveed is a prescription medicine that contains testosterone. Aveed is used to treat adult males who have low or no testosterone due to certain medical conditions.

Aveed is only for adult males who need testosterone replacement therapy and when the benefit of receiving Aveed is more than the risk of a pulmonary oil microembolism (POME) and anaphylaxis.

Your healthcare provider will test your blood before you start and while you are taking Aveed.

It is not known if Aveed is safe or effective to treat men who have low testosterone due to aging.

It is not known if Aveed is safe and effective for use in children younger than 18 years old. Improper use of Aveed may affect bone growth in children.

Aveed is a controlled substance (CIII) because it contains testosterone that can be a target for people who abuse prescription medicines.

Aveed is not meant for use in women.

What is the most important information I should know about Aveed?

Aveed may cause serious side effects, including:

  • A serious lung problem. Aveed can cause a serious lung problem called a POME reaction. POME is caused by tiny droplets of oil that have traveled to the lungs. Symptoms of a POME reaction may include:

    You may need emergency treatment in a hospital, especially if these symptoms get worse over the 24 hours after your Aveed injection.

    These side effects may happen during or right after each injection. To be sure that you are not having one of these reactions:
    • You need to stay in the doctor’s office, clinic, or hospital for 30 minutes after having your Aveed injection so that your doctor can watch you for symptoms of POME or a serious allergic reaction.
