Important Considerations for Testosterone Patches
Efficacy and Monitoring
- Testosterone patches produce normal serum testosterone concentrations when used appropriately 1
- Peak testosterone values occur 6-8 hours after patch application 1
- Monitoring should occur 2-3 months after treatment initiation and after any dose change 1
Safety Considerations
- Transdermal testosterone preparations are associated with skin reactions, mainly erythema or pruritus 1
- Patches have higher rates of skin reactions (up to 66% of users) compared to gel preparations (5%) 1
- Unlike oral testosterone preparations (which are strongly discouraged in the US due to hepatotoxicity), transdermal patches do not appear to be associated with hepatic dysfunction 1
Clinical Pitfalls and Caveats
- Testosterone patches may have issues with adherence to skin, affecting consistent delivery 1
- The FDA required labeling changes in 2015 to inform about possible increased risk of heart attack and stroke with testosterone preparations 1
- Testosterone therapy may exacerbate sleep apnea, particularly in men with other risk factors 1
- Testosterone replacement therapy can compromise fertility due to down-regulation of gonadotropins 1
Comparative Considerations
- Transdermal patches minimize the issue of variable absorption seen with gels 1
- Patches generally cost more than injectable options 1
- Patches provide more stable testosterone levels compared to injections, which may reduce cardiovascular risk 1
- Patches restore normal circadian rhythm of testosterone levels when used daily, unlike periodic injections 2
When considering testosterone replacement therapy, patches offer a non-invasive option with relatively stable hormone levels, though skin irritation remains a significant limitation for many patients.
