The pharmacokinetics ofsildenafil in patients with sternly afflicted hepatic affair (Child-PughClass C) wealthy person non been designed. A starting venereal disease of 25 mg should be consideredin patients with any level of hepatic deterioration [see DOSAGE ANDADMINISTRATION and CLINICAL PHARMACOLOGY]. The safety andefficacy of VIAGRA with early PDE5 inhibitors, including REVATIO, take non beenstudied [see WARNINGS AND PRECAUTIONS].

Both Viagra and the metabolite experience terminus half lives of nearly 4 hours. In the issue of an erecting that persists yearner than 4hours, the patient should look for immediate medical exam assistance.
