What is Testosterone patch?
Testosterone patches are designed to deliver testosterone across the skin over a defined wear period. Local skin reactions and product availability are important practical considerations.
Approved-use context
Where licensed and available, patches are used for replacement therapy in confirmed hypogonadism. A product may be discontinued or unavailable in a particular country even if older guidance still describes it.
How it works
The patch provides controlled transdermal delivery into systemic circulation. Exposure depends on correct adhesion and use of authorised application sites.
Formulations and schedules
Patch strength, wear time and permitted sites are product-specific. Users should not adapt old instructions from a discontinued or different product.
