XYOSTED is a prescription medicine used to treat adult men who have low or no testosterone due to certain medical conditions. It is not known if XYOSTED is safe and effective for use in children younger than 18 years old or for the treatment of men who have low testosterone due to aging. Improper use of XYOSTED may affect bone growth in children.

Your doctor will diagnose hypogonadism based on a combination of your symptoms and laboratory testing. A diagnosis of low testosterone is confirmed by at least two separate early morning blood tests showing total testosterone levels below 300 ng/dL.

In a clinical study of 150 patients on XYOSTED*, 90% had testosterone levels in the normal range† by week 12. Individual results may vary.

* Studied for 52 weeks when taken every week as directed. Achieving desired blood levels may require dose adjustments at Week 7 based upon Week 6 blood levels. Some patients fell below minimum level of 300ng/dL despite dose adjustments.
“Normal Range” is defined as 300-1,100 ng/dL.

The most common side effects are increased hematocrit, hypertension, increased PSA, injection site bruising, headaches, back pain, increased blood creatine phosphokinase, and injection site hemorrhage, each of which occurred in fewer than 15% of participants in two clinical studies in a total of 283 men who received XYOSTED once a week for up to one year. Please refer to the Important Safety Information for full Warnings and Precautions.

In a one-year clinical trial of 150 men receiving 1,519 injections, 99.4% of injections were reported as painless. Injection site reactions can occur, including: bruising, bleeding, redness, and hardness in 12.7% of study patients at one time during the 52 week study period.

The needle in the XYOSTED auto-injector is not visible before or during injection. The device is designed to be user-friendly and discreet, with a collar-activated mechanism that hides the needle.

Yes, you can travel with XYOSTED.* Be sure to pack it in your carry-on luggage if you’re flying. You may also want to bring a copy of your prescription and a letter from your doctor to help with airport security.

* Store XYOSTED at room temperature (68°F to 77°F or 20°C to 25°C). Do not refrigerate or freeze. Keep it in the original packaging to protect it from light and out of reach of children.

You will need to contact your insurance provider to find out if you are covered.
