Xyosted (Testosterone) - Subcutaneous


Xyosted (testosterone) contains a boxed warning for the risk of blood pressure increases. Before starting Xyosted, your healthcare provider may check your baseline cardiovascular risk and blood pressure levels. They will also monitor for and treat blood pressure increases during treatment.

What Is Xyosted?

Xyosted (testosterone) is a prescription medication used to treat low testosterone levels in males (sex assigned at birth) 18 years and older. It belongs to a drug class called androgens.

Your body naturally makes certain hormones like testosterone and dihydrotestosterone (DHT). These hormones help develop male sex organs and maintain secondary sex characteristics. Xyosted works like these hormones in males to increase testosterone levels.

Xyosted is a controlled substance (Schedule III) because it has the potential for abuse and dependency. It is a weekly injection only given under the skin (subcutaneously). It is preservative-free and contains sesame oil. Other forms of testosterone injection are available for intramuscular (shot into the muscle) use, but Xyosted should only be administered subcutaneously.

Xyosted contains a boxed warning, the FDA's strictest safety warning, for the risk of blood pressure increases.
