PDE5 inhibitor
Vardenafil and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Vardenafil (Vardenafil) at 5mg, 10mg, 20mg may directly alter certain lab parameters, indirectly affect others through its mechanism, or interfere with the assay itself in rare cases. Knowing what is normal, what is monitored and what is artefact prevents unnecessary worry.
Lab effects of Vardenafil
Possible lab effects of Vardenafil are listed in the prescribing information. They typically reflect the medication's mechanism: changes in liver enzymes, kidney function markers, blood counts, electrolytes, glucose or lipids depending on the agent. Vardenafil selectively inhibits PDE5, the enzyme that breaks down cyclic guanosine monophosphate in the corpus cavernosum. Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Vardenafil, baseline labs before starting Vardenafil and periodic monitoring during treatment are recommended for many medications in PDE5 inhibitor. The frequency depends on the agent and on individual risk factors. Fasting requirements for specific tests are independent of Vardenafil dosing — the test instructions take precedence.
