Fildena Chewable 100 mg contains sildenafil citrate, the same active ingredient found in Viagra, which is widely used to treat erectile dysfunction. It works by increasing blood flow to the penis, enabling men to achieve and sustain an erection when sexually aroused. Unlike traditional tablets, Fildena Chewable 100 mg can be taken without water, and its chewable format often leads to quicker onset of action.
