Uses for testosterone
Testosterone topical gel is used for the treatment of males whose bodies do not make enough natural testosterone, a condition called hypogonadism. Testosterone is a male hormone responsible for the growth and development of the male sex organs and maintenance of secondary sex characteristics.
Testosterone is available only with your doctor's prescription.
Before using testosterone
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For testosterone, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to testosterone or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of testosterone topical gel in children. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of testosterone topical gel in the elderly. However, elderly patients may be at an increased risk for developing heart and blood vessel problems, or prostate problems (including prostate cancer), which may require caution in patients receiving testosterone.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using testosterone.

Proper use of testosterone
Testosterone comes with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions.
Androgel® or Fortesta® is available in two forms: individual packets or multi-dose pump. Vogelxo™ is available in three forms: individual packets, multi-dose pump, or tube. If you are using the pump gel for the first time, prime the pump before measuring out your first dose. Hold the pump over a sink and press the pump all the way down at least 3 times (Androgel® or Vogelxo™) or 8 times (Fortesta®) or until the gel begins to flow freely. Rinse the medicine discarded into the sink down the drain. Place the palm of your hand under the pump and press the pump the proper number of times to measure out your correct dose.
If you are using the gel in foil packets, tear the packet completely open along the perforation. Squeeze the entire contents directly onto the skin where you will apply the gel. You may also empty the packet into the palm of your hand and then apply the medicine. Throw away the empty foil packet in a place where children and pets cannot reach it.
Axiron® is available in two forms:
- Pump actuated metered dose bottle—For first time use, prime it before measuring out your first dose. Hold the bottle over a sink and press the pump all the way down at least 3 times. Rinse the medicine discarded into the sink down the drain. Place the palm of your hand under the pump and press the pump the proper number of times to measure out your correct dose.
- Twist actuated metered dose bottle—For first time use, prime it before measuring out your first dose. Hold the bottle over a sink and twist the dose dial on the bottle. Rinse the medicine discarded into the sink down the drain. Repeat this two more times. Completely twist (180° turn) the dose dial one time after priming to get your correct dose.
AndroGel® is available in two dosage strengths: AndroGel® 1% and AndroGel® 1.62%. AndroGel® 1% is used differently than AndroGel® 1.62%, even though they are both applied to the skin. Do not change your dose unless your doctor tells you to.
To use the gel:
- Make sure that you wash your hands with soap and water before and after applying the gel.
- Apply AndroGel® 1% to a clean, dry, intact skin of the shoulders, upper arms, or abdomen (stomach), unless your doctor tells you to use it on another part of your body. AndroGel® 1.62% should only be applied to a clean, dry intact skin of the shoulders and upper arms. Fortesta® should be applied to a clean, dry, intact skin of the front or inner thighs. Vogelxo™ should be applied to a clean, dry, intact skin of the shoulders or upper arms. Do not apply Vogelxo™ to your abdomen or stomach. Do not apply testosterone to your scrotum or your penis. Do not use the medicine on skin that has a cut, scrape, or other type of injury.

The gel or solution form can be transferred to another person if they touch or rub the skin where the medicine was placed or if some of it remains on your hands. To keep this from happening, wash your hands again after applying the medicine. Also, wash the area where you applied the gel with soap and water if you expect to have a skin-to-skin contact with another person.
Testosterone is flammable until it dries on the skin. Do not use it near heat, an open flame, or while smoking.
The dose of testosterone will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of testosterone. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions while using testosterone
It is very important that your doctor check your progress at regular visits to see if the medicine is working properly. Blood tests may be needed to check for any problems or unwanted effects.
Testosterone should not be used by women. Testosterone may cause birth defects if a pregnant woman comes in contact with the medicine. Make sure your doctor knows if your sexual partner is pregnant. If a pregnancy occurs while you are using testosterone, tell your doctor right away.
Testosterone may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Children and women should avoid contact with the unwashed or unclothed area where the testosterone gel has been applied. If another person does accidentally get testosterone on the skin, wash the area with soap and water as soon as possible.
Tell your doctor if your female partner or child starts to have male-like body changes while you are using testosterone. Such changes may include hair growth on the face, a deeper voice, or a significant increase in acne. The changes may also include an enlarged penis or clitoris, early development of pubic hair, increased erections or sexual desire, aggressive behavior, and bone problems.
Testosterone may cause blood clotting problems. Check with your doctor right away if you have a chest pain, trouble breathing, coughing up blood, numbness or weakness in your arm or leg, or on one side of your body, or pain in your lower leg (calf) while using testosterone.
Testosterone may increase your risk of having heart or blood vessel problems, including a heart attack or stroke. Tell your doctor right away if you have chest pain that may spread to your arms, jaw, back, or neck, faintness, headache, nausea, vomiting, trouble breathing, trouble seeing or speaking, or unusual sweating.
In some cases, testosterone may decrease the amount of sperm men make and affect their ability to have children. If you plan to have children, talk with your doctor before using testosterone.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Testosterone may cause fluid retention (edema) in some patients. Tell your doctor right away if you have bloating or swelling of the face, arms, hands, lower legs, or feet, tingling of the hands or feet, or unusual weight gain or loss.
Testosterone may affect the results of the prostate specific antigen (PSA) test, which may be used to detect prostate cancer. Make sure you tell all of your doctors that you are using testosterone.
Before you have any medical tests, tell the medical doctor in charge that you are using testosterone. The results of some tests may be affected by testosterone.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
