Viktoris 20 mg (Tadalafil)

Adult dose

Use in adult men The recommended dose of this medicine is 10mg, taken with or without food before anticipated sexual activity. For patients in whom tadalafil 10mg does not produce an adequate effect, 20 mg may be tried. This medicine may be taken at least 30 minutes before sexual activity. The maximum recommended dosing frequency is once daily. Long-term safety after extended daily dosing has not been established, and because the effect of this medicine usually lasts for more than a day, continuous daily administration is strongly discouraged. [See section 1. Warnings and Pharmacodynamic Properties, 11.1)] Use in elderly men No dosage adjustment is required in elderly patients. Use in men with renal impairment No dosage adjustment is required in patients with mild to moderate renal impairment. The maximum recommended dose in patients with severe renal impairment is 10mg. [See 11.2) Pharmacokinetic Properties]. Use in men with hepatic impairment The recommended dose of tadalafil tablets is 10mg, taken with or without food before anticipated sexual activity. Clinical data on the safety of tadalafil tablets in patients with severe hepatic impairment (Child-Pugh Class C) are limited; therefore, if prescribing, the physician should carefully assess the individual benefit/risk. There are no data on administering doses higher than 10mg to patients with hepatic impairment. [See section 3. Use with caution in the following patients and Pharmacokinetic Properties, 11.2)]. Use in men with diabetes No dosage adjustment is required in patients with diabetes.
