Axiron is a brand-name testosterone replacement therapy. It’s a topical testosterone solution that comes in a metered-dose pump and is applied to the underarm (axilla).
What it’s used for
- Adult men with low testosterone (hypogonadism) due to certain medical conditions.
How it’s used
- Dosing is prescribed by a clinician (often around two sprays once daily, delivering about 60 mg of testosterone), applied to a clean, dry underarm.
- Do not apply to other parts of the skin or to the genitals.
- After applying, wash your hands and allow the area to dry before dressing.
- Keep the application site away from others for a few hours to minimize transfer via skin contact.
Important safety and warnings
- Not for use in women or children. It can cause harm if transferred to others, including females and children, leading to virilization.
- Do not use if you have breast cancer, or prostate cancer, or if you are pregnant or breastfeeding.
- Testosterone therapy can raise red blood cell counts, worsen sleep apnea, affect PSA (prostate-specific antigen) levels, and interact with other medicines.
- Tell your clinician about other medicines you take (e.g., anticoagulants like warfarin, insulin or other diabetes meds, certain antidepressants, or CYP450 interactants).
Common and serious side effects
- Common: skin irritation at the application site, acne, oily skin, increased facial/body hair, mood changes, changes in libido, headache, fluid retention.
- Serious (seek care): symptoms of heart or liver problems, signs of a clot (unexplained chest pain, shortness of breath, swelling in legs), symptoms suggesting prostate issues (urinary changes, blood in urine), severe allergic reaction.
Monitoring and follow-up
- Your clinician may monitor testosterone levels, PSA, and hematocrit (to check for polycythemia), and assess for side effects or cardiovascular risk.
Storage, disposal, and handling
- Store at room temperature, away from heat and moisture.
- Keep out of reach of children.
- Follow local guidelines for disposal and for safe, complete emptying of the pump.
