Fildena 120 is a medication used to treat erectile dysfunction (ED). It contains 120 mg of sildenafil citrate, the same active ingredient found in Viagra. Sildenafil citrate works by increasing blood flow to the penis, which helps achieve and maintain an erection in response to sexual stimulation. Fildena 120 is typically taken about 30 to 60 minutes before sexual activity. It is effective for up to 4-6 hours. It’s important to use Fildena 120 under the supervision of a healthcare provider.
