Testosterone belongs to a group of hormones called androgens (male hormones). Testosterone is responsible for the growth and development of the male sex organs as well as male sex characteristics such as chest hair, facial hair, pubic hair, voice changes, and muscle growth. A deficiency of testosterone can result in underdeveloped testes or erectile dysfunction (difficulty getting or keeping an erection).
Testosterone nasal gel is used to treat testosterone deficiency. Testosterone nasal gel should only be used if testosterone deficiency has been confirmed by symptoms and blood tests.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blood tests: Your doctor may recommend that you have regular blood tests while using this medication to check whether the medication is working and whether you are having certain side effects. Also, the use of testosterone may interfere with a number of laboratory tests. Tell all health professionals administering these tests that you are using this medication.
Breast and prostate cancer: Long-term use of androgens, including testosterone, may increase your risk of developing breast or prostate cancer. Discuss any concerns you may have with your doctor.
Diabetes: Testosterone nasal gel may cause a loss of blood glucose control, and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.
If you have diabetes or are at risk for developing diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Men and the heart: Testosterone can cause increased blood pressure and may cause fluid to build up in the body. Both conditions can increase the risk of certain types of heart disease.
There may be an increased risk of heart-related events (e.g., heart attacks, stroke, heart-related death) in men who take testosterone hormone replacement medications. Before you start treatment, tell your doctor if you have diabetes or heart disease, have had a previous heart attack or stroke, or have cardiovascular risk factors (e.g., high blood pressure, smoking, or cholesterol). If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: The liver plays an important role in breaking down and removing testosterone from the body. Certain androgens have also been linked to decreased liver function, which can become life-threatening. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Nasal problems: Due to a lack of long-term safety information, this medication should not be used by people who have a history of nasal problems, sinus disease, nasal or sinus surgery, a nasal fracture within the previous 6 months, a nasal fracture that caused a deviated septum, or inflammatory disorders affecting the lining of the nose such as Sjögren’s syndrome.
Nasal sprays: Testosterone nasal gel may be used with decongestant nasal sprays (e.g., oxymetazoline). It should not be used with any other nasal sprays.
Prostate problems: Men with benign prostatic hypertrophy (BPH), an enlarged prostate gland, may experience an increase in their symptoms. If you have BPH, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Sleep disorders: Treatment with testosterone may cause sleep apnea (interruption of breathing during sleep). If you have sleep apnea or risk factors for sleep apnea, such as being overweight or having a chronic lung disease, discuss this with your doctor.
Sperm counts: This medication may reduce sperm counts if high doses are used or if it is used for a prolonged period.
Pregnancy and breast-feeding: This medication should not be used by women, especially pregnant or breast-feeding women. It may have unwanted effects on the developing child, including masculinization of female children. Pregnant or breast-feeding women should avoid skin contact with testosterone application sites on men who are using this medication.
Children: Testosterone use can cause growth in children to be stopped early. If this medication is being used to treat males with delayed puberty due to decreased hormone production, the child’s final height may be lower than expected. Use of this medication by children should be carefully supervised by the doctor.
Seniors: Seniors may have an increased risk for prostate enlargement and should be evaluated for prostate cancer before starting testosterone replacement therapy.
