Fildena Chewable 100 mg is a medication containing sildenafil citrate, which is primarily used to treat erectile dysfunction (ED). Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, similar to the active ingredient in Viagra, which works by increasing blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. Fildena Chewable 100 mg tablets are designed to be chewed rather than swallowed whole, making them a convenient option for individuals who have difficulty swallowing tablets. They are typically taken orally, usually about 30 minutes to 1 hour before anticipated sexual activity.
