Axiron vs. Androgel comparison
The active ingredient in both Axiron and Androgel is synthetic testosterone, and both medications consist of topical gel that allows the testosterone to absorb through the skin. Doctors prescribe these drugs to adult males who for some reason, whether a physical condition or a result of aging, are lacking normal testosterone levels.
The only difference between these two gel medications is where on your body you're supposed to put it. Axiron gel is applied in the armpits, while Androgel is applied to the upper arm, shoulders, or abdomen.
What are Axiron and Androgel?
Both Axiron and Androgel are skin ointments that deliver laboratory-manufactured testosterone through the skin. Pharmaceutical researchers developed this therapy in part because testosterone production in men tends to decline as they age, causing muscle loss, bone weakness, loss of libido, erectile dysfunction, and fat accumulation. Scientists sometimes refer to this slowdown in testosterone production as "andropause," but physiologically, it's only superficially similar to menopause in women, which is a much more drastic hormonal change.
Testosterone (also referred to as an "androgen") production in men starts ramping up during puberty, and testosterone production by the testes is the end hormonal result of a production chain involving the brain and endocrine system. The hypothalamus of the brain, a structure behind the base of the forebrain, secretes gonadotropin-releasing hormone, which stimulates the nearby pituitary gland to release luteinizing hormone, which then stimulates the testicles to produce testosterone.
Testosterone, a lipid-soluble (fat-soluble) hormone, can pass through the membranes of cells because cell membranes are made of fats. Inside the cell, floating around in the cytoplasm, are protein molecules called androgen receptors (AR), which are shaped in such a way they fit like a puzzle piece with testosterone molecules. When a testosterone molecule locks into the androgen receptor, the whole assembly migrates into the cell nucleus where the DNA is stored. The testosterone-AR assembly interacts directly with the DNA to help the cell "read" the code, allowing it to produce the necessary proteins to maintain muscle mass, hair growth, genital function and other male sex characteristics.
Axiron and Androgel help replace the missing testosterone to help maintain mood, sexual function, muscle mass, and bone strength.

What are the uses for Axiron and Androgel?
Axiron and Androgel are both testosterone replacement products used for men 18 years old or older for treatment of low testosterone (low T) or absence of testosterone due to primary hypogonadism or hypogonadotropic hypogonadism. It is most often used for treatment of a slowdown in testosterone production in aging men.
What are the side effects of Axiron and Androgel?
Other side effects include:
- acne, enlarged breasts,
- high blood pressure,
- mood swings,
- changes in libido,
- increased serum prostate specific antigen (PSA) levels, and
- increased volume of red blood cells.
Other important side effects include:
How should Axiron and Androgel be taken (dosage)?
The recommended dose is 30 to 120 mg daily once every morning at approximately the same time. The starting dose is 30 mg (1 pump actuation) applied to each armpit (60 mg total). The total daily dose may be decreased to 30 mg or increased to 90 mg (3 pump actuations) or from 90 to 120 mg (4 pump actuations) based on blood testosterone levels. Hands should be washed thoroughly with soap and water after applying Axiron.
The recommended starting dose is 50 mg applied once daily to the skin of shoulders, upper arm, or abdomen. The dose may be increased based on blood testosterone levels. The hands should be washed thoroughly with soap and water after applying Androgel.
Which drugs interact with Axiron and Androgel?
Testosterone may decrease blood glucose levels. Therefore, less insulin may be required in diabetic patients. Testosterone may increase the the action of the blood thinner warfarin (Coumadin), increasing the risk of bleeding. Combining steroids with testosterone may increase fluid retention.
Are Axiron and Androgel safe to take during pregnancy or while breastfeeding?
Women in general should not only avoid ever using Axiron and Androgel, but they should also avoid even accidental contact with the medication and parts of men's bodies where they have applied the ointment. Testosterone is harmful to a developing fetus and can cause adverse side effects to a nursing baby.
Axiron and Androgel are both testosterone supplements to help men with low testosterone (Low-T), whether because of aging or some medical condition. Both medications come in the form of topical gel that allows the synthetic testosterone to absorb through the skin. Learn about Axiron and Androgel dosage, side effects, and other facts.

Erectile Dysfunction (ED, Impotence)Erectile dysfunction (ED, impotence) is the failure to achieve or maintain an erection. There are many potential underlying causes of erectile dysfunction, including stress and emotional problems, brain dysfunction, problems with blood supply to the penis, and structural problems with the penis. Erectile dysfunction is diagnosed by taking the patient's history and physical exam. Blood tests measuring kidney function and blood sugar, cholesterol, hormone, and prostate-specific antigen (PSA) levels may be ordered. Urinalysis, ultrasound, and other more sophisticated tests may be required. The treatment of erectile dysfunction depends on the underlying cause. Medications, penile injections, penile implants, and vacuum devices may be used. Treatment for erectile dysfunction is usually successful. The patient should manage heart disease risk factors (high blood pressure, high cholesterol, diabetes) as they are related to erectile dysfunction risk.
Low Testosterone (Low T)
Low testosterone (low-T) can be caused by conditions such as type 2 diabetes, obesity, liver or kidney disease, hormonal disorders, certain infections, and hypogonadism. Signs and symptoms that a person may have low-T include:
- Increased body fat
- Weight gain
- Reduced muscle
- Decreased sex drive
- Worsening of congestive heart failure or sleep apnea.
Low-T can be treated with testosterone therapy in the form of gels, injections, pellets, or skin patches. Side effects of testosterone treatment include:
- Hair loss
- Change in libido

testosterone gel-topicalTestosterone gel (Androgel) is a gel containing testosterone and is prescribed for the treatment of low testosterone levels. Side effects, drug interactions, and patient safety information should be reviewed prior to taking this medication.
Testosterone Therapy to Treat EDThe testicles produce testosterone a hormone responsible for the proper development of male sexual characteristics. Testosterone is also important for maintaining muscle bulk, adequate levels of red blood cells, bone growth, sense of well-being and sexual function. As a man ages, the amount of testosterone in his body gradually declines and the significance of testosterone decline is controversial and poorly understood. The treatment for testosterone deficiency can include intramuscular injections, generally every two or three weeks, testosterone patch worn either on the body or on the scrotum, testosterone gel, mucoadhesive material applied above the teeth twice a day, or oral tablets.
