Monitoring liver function while taking Vidalista 80 mg is essential because this medication, like other PDE5 inhibitors, is metabolized primarily in the liver. A qualified healthcare professional, such as a physician or gastroenterologist, should oversee liver function assessments. This is particularly important for individuals with pre-existing liver conditions, such as hepatitis, cirrhosis, or fatty liver disease. Regular liver function tests (LFTs), including measurements of ALT, AST, ALP, and bilirubin levels, help detect any early signs of liver stress or damage. Self-monitoring is not sufficient; professional supervision ensures timely dose adjustments or discontinuation if abnormal liver results occur, maintaining both safety and efficacy of Vidalista 80.
