Vidalista 10 is used to treat erectile dysfunction (ED) in men, and it contains the active ingredient Tadalafil, which helps increase blood flow to the penis to support a firm and lasting erection during sexual activity. Take one tablet about 30 to 60 minutes before you plan to have sex. Tadalafil doesn’t work instantly—sexual stimulation is still required for it to be effective. One of the major advantages of Vidalista 10 is its long duration of action—up to 36 hours, which offers more flexibility and spontaneity in your sexual activity.
