Testosterone Nasal Gel

pronounced as (tes tos' ter one)

Why is this medication prescribed?

Testosterone nasal gel is used to treat symptoms of low testosterone in adult men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Testosterone nasal gel is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain), or hypothalamus (a part of the brain) that cause hypogonadism. Your doctor will order certain lab tests to check your testosterone levels to see if they are low before you begin to use testosterone. Testosterone should not be used to treat the symptoms of low testosterone in men who have low testosterone due to aging ('age-related hypogonadism'). Testosterone is in a class of medications called androgenic hormones. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Testosterone works by replacing testosterone that is normally produced by the body.

How should this medicine be used?

Testosterone comes as a gel to apply to the inside of the nose using a dispenser pump. It is usually used three times a day in each nostril. To help you remember to apply testosterone nasal gel, apply it at about the same times each day and space your doses about 6 to 8 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use testosterone nasal gel exactly as directed. Do not apply more or less of it or apply it more often than prescribed by your doctor.

If you have severe cold symptoms (sneezing, congestion, runny nose), tell your doctor. Your doctor may decide to stop your medication until you are better or change you to another medication.

Before you use testosterone nasal gel for the first time, read the written directions that come with it. To use the nasal gel, follow these steps:

  1. Blow your nose to clear your nasal passages.
  2. Remove the cap from the dispenser.
  3. To prime the pump before the first use, hold the dispenser upside down over a sink. Slowly press down on the pump 10 times. Always discard the extra medication that comes out after priming the pump down the drain with warm water. Wipe the tip of the dispenser with a clean, dry tissue.
  4. Look in a mirror and put your right first (index) finger on the pump and slowly insert the tip of the dispenser into your left nostril until your finger on the pump touches the bottom of your nose. Gently tilt the dispenser so that the hole in the tip touches the outside wall in your nostril. Slowly press down on the pump until it stops. Remove the tip of the dispenser from your nostril and repeat these steps in your right nostril, using your left first (index) finger on the pump.
  5. Wipe the tip of the dispenser with a clean, dry tissue and put the cap back on the dispenser pump.
  6. Press your nostrils together just below the middle of your nose and lightly rub your nostrils together.
  7. Do not sniff or blow your nose for 1 hour after you apply testosterone nasal gel.
  8. Wash your hands with soap and warm water right away if testosterone gel gets on your hands.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

People who use higher doses of testosterone than recommended by a doctor may also experience withdrawal symptoms such as depression, extreme tiredness, craving, irritability, restlessness, loss of appetite, inability to fall asleep or stay asleep, or a decreased sex drive, if they suddenly stop using testosterone. Be sure to use testosterone nasal gel exactly as directed by your doctor.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Store testosterone nasal gel in a safe place so that no one else can use it accidentally or on purpose. Keep track of how much medication is left so you will know if any is missing.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
