Lab monitoring on Stendra: which tests and how often
Many chronic medications including Stendra (Avanafil) come with a recommended laboratory monitoring schedule — baseline labs before starting, follow-up checks at defined intervals, and additional tests if symptoms or risk factors change. Knowing what is monitored, why and how often takes the mystery out of routine appointments at 50mg, 100mg, 200mg.
Tests typically monitored on Stendra
According to the prescribing information for Avanafil, the standard monitoring panel for Stendra usually includes: liver function (ALT, AST), kidney function (creatinine, eGFR), electrolytes (potassium, sodium), and any class-specific markers (e.g. lipid panel, glucose, hormone levels, blood counts) relevant to Erectile Dysfunction (ED). Avanafil selectively inhibits phosphodiesterase type 5 (PDE5) in the corpus cavernosum, increasing cGMP and enhancing nitric-oxide-mediated vasodilation in response to sexual stimulation.
Frequency and triggers
Baseline labs before starting Stendra establish the reference. Follow-up at 4–12 weeks is typical for most chronic medications, then annually if stable. More frequent monitoring is triggered by dose changes, new symptoms, intercurrent illness, or other interacting medications added to the regimen at 50mg, 100mg, 200mg.
