Tadacip 20 is a medication that can be beneficial for erectile dysfunction (ED). Tadacip 20 contains tadalafil, which is the same active ingredient found in Cialis. Tadalafil works by increasing blood flow to the penis, helping to achieve and maintain an erection. Tadalafil is effective in treating ED by relaxing the blood vessels in the penis, allowing for increased blood flow when sexually aroused. Typically, Tadacip 20 is taken orally, with or without food, about 30 minutes before sexual activity. Unlike some other ED medications, tadalafil can also be used in a lower daily dose for continuous treatment.
