Androgel is not approved for use in women. Accidental exposure can cause virilization, including deepening of the voice and increased body hair.
Clinical improvement in energy levels, libido, and muscle mass is usually observed within a few weeks, but full therapeutic effect may require 3-6 months of consistent use.
Allow the gel to dry completely (at least 2 hours) before dressing. If staining occurs, wash the affected clothing promptly with warm water and detergent.
Avoid showering, swimming, or heavy sweating for at least 2 hours after application to ensure adequate absorption.
Testosterone is not a prohibited substance in standard workplace drug screens, but athletes subject to anti-doping regulations should disclose use to relevant authorities.
No special clothing is required, but applying the gel to a clean, dry area and washing hands afterward minimizes transfer to others.
A 1 % gel contains 10 mg of testosterone per gram of gel. Higher concentrations deliver more testosterone per gram, potentially requiring smaller application volumes.
Moderate alcohol intake does not directly affect the gel’s absorption, but excessive drinking can impair liver function and hormone balance.
Severe itching, swelling, rash, or hives at the application site may indicate hypersensitivity. Discontinue use and seek medical attention promptly.
Rotating between approved skin areas (shoulders, upper arms, abdomen) helps prevent local skin irritation and ensures even absorption.
Androgel is a topical hormone therapy product that delivers testosterone through the skin. The active ingredient is testosterone topical, formulated as a 1 % gel in a single-use sachet. In Hong Kong, Androgel is a prescription medication regulated by the Department of Health’s Drug Office. It is used to treat men whose bodies do not produce adequate testosterone, a condition known as male hypogonadism.
Testosterone gel applied to clean, dry skin is absorbed into the bloodstream, raising circulating testosterone levels. Testosterone binds to androgen receptors in target tissues, promoting the development and maintenance of male secondary sexual characteristics, muscle mass, bone density, and libido. The gel provides a steady, transdermal route of delivery that bypasses first-pass metabolism in the liver, resulting in more stable serum concentrations compared with oral formulations. Onset of clinical effect typically occurs within a few days, with peak levels reached after several weeks of consistent use.
Androgel is approved in Hong Kong for testosterone replacement therapy (TRT) in adult males with confirmed hypogonadism. Indications include:
The medication is intended for adult men only; it is not approved for use in children or adolescents.
These effects are generally transient and may lessen with continued use.
If any serious symptom occurs, medical attention should be sought promptly.
Patients should disclose all current medications, supplements, and herbal products to their healthcare provider before starting Androgel.
