What is Natesto Nasal Gel?

Natesto is a prescription medicine that contains testosterone and is used to treat adult males who have low or no testosterone due to certain medical conditions. Your doctor will test the testosterone level in your blood before you start and while you are using Natesto.

Natesto should not be used by men with breast cancer, or known or suspected prostate cancer.

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

Safety and effectiveness of Natesto have not been established in children younger than 18 years old, and Natesto should not be used by children. Natesto use by children may affect bone growth.

Natesto is a controlled substance (CIII) because it contains testosterone that can be a target for people who abuse prescription medicines. Keep your Natesto in a safe place to protect it. Never give your Natesto to anyone else, even if they have the same symptoms you have. Selling or giving away this medicine may harm others and is against the law.

Natesto is not meant for use in women.
