Vidalista 60 contains tadalafil 60 mg, which is a higher-strength tadalafil product. Before prescribing tadalafil—especially at higher doses—a healthcare professional may consider your overall health, medications, and certain lab results rather than relying on one single test. Lab results and health measurements that may affect the decision include: Kidney function tests Serum creatinine eGFR (estimated glomerular filtration rate) Reduced kidney function can affect how tadalafil is cleared from the body and may require dose adjustments or caution. Liver function tests ALT, AST, bilirubin, and other liver markers Significant liver impairment may change how tadalafil is processed. Blood pressure measurements Low blood pressure or poorly controlled high blood pressure can affect safety. Cardiovascular assessment Not usually a “lab test,” but a clinician may review heart history, exercise tolerance, and sometimes tests such as an ECG if indicated. Blood sugar tests (if relevant) Fasting glucose or HbA1c Diabetes can contribute to ED and may affect overall treatment planning. Hormone testing (when symptoms suggest it) Testosterone levels may be checked if low libido, fatigue, or suspected hormone problems are present. A few important points: Vidalista 60 mg is a high dose; many tadalafil treatment regimens use lower doses, so a clinician may consider whether a lower dose would be safer and sufficient. Tadalafil should not be used with nitrate medicines because of the risk of a dangerous blood-pressure drop. If you have kidney disease, liver disease, heart disease, or take multiple medicines, medical review is especially important.
