However, physical stimulation is still necessary for the medication to work. The typical recommended dosage of Filitra 20 is 20 mg, taken orally as needed, about 30 minutes to 1 hour before engaging in physical activity. It's important to follow the dosing instructions provided by your healthcare provider for safe and effective use.
