WARNINGS AND PRECAUTIONS
There is very little information from clinical trials with testosterone in the older male (>65 years of age) to support safe use for a long period of time.
DEPO-TESTOSTERONE is not recommended for use in children < 18 years of age.
DEPO-TESTOSTERONE can cause changes in your vision. It is called chorioretinopathy.
You should not use testosterone in an attempt to reduce weight and increase muscle, or improve athletic performance as it may cause serious health problems.
You should not use testosterone to treat sexual dysfunction or male infertility.
DEPO-TESTOSTERONE contains benzyl alcohol. The preservative benzyl alcohol has been associated with serious adverse events, including the “gasping syndrome” (difficulty in catching breath, low blood pressure, slow heart rate), and death in pediatric patients. Premature and low-birth weight infants may be more likely to develop toxicity.
Pregnancy: Benzyl alcohol can cross the placenta.
Before using DEPO-TESTOSTERONE, talk to your doctor if you:
- have difficulty urinating due to an enlarged prostate. Older patients may have a higher risk of developing an enlarged prostate or prostate cancer;
- have prostate cancer (confirmed or suspected);
- have liver, kidney or heart disease;
- have high blood pressure (hypertension);
- have diabetes;
- have breathing problems during sleep (sleep apnea);
- have heart or blood vessels problems or a history of these problems such as heart attack, stroke, or blood clots in the lungs or the legs.
Drug Abuse and Dependence: DEPO-TESTOSTERONE contains testosterone. Testosterone is a controlled substance because some people take it in high doses (abuse it), even if their body is making enough testosterone. Taking too much (abusing) testosterone can cause serious health problems, which can even lead to death (see Overdose).
Individuals who have abused testosterone may experience withdrawal symptoms lasting for weeks or months which include, but are not limited to: changes in mood, and appetite, as well as fatigue, insomnia, decreased sex drive and loss of function of the testes and ovaries.
Drug dependence in individuals using approved doses of testosterone for approved indications has not been documented.
