Fildena 100 is one of the most well-known erectile dysfunction (ED) medications available today. While it may not be as famous a brand name as Viagra or Cialis, Fildena 100 has gained significant popularity as a cheaper alternative to those flagship drugs. However, for those unfamiliar with Fildena, some key questions remain - what exactly is it, how does it work, and is it a safe and effective ED treatment option? Let's take a closer look.

Fildena 100 belongs to a class of drugs known as PDE5 inhibitors. These work by relaxing the blood vessels and increasing blood flow to the penis during sexual stimulation. The active ingredient in Fildena 100 is sildenafil citrate, which is the same active drug found in Pfizer's branded Viagra pills. In essence, Fildena 100 contains the exact same medicine as Viagra, but is available as a lower-cost generic alternative.

When taken as directed, Fildena 100 can help treat ED by allowing increased blood flow to facilitate and maintain an erection long enough to have successful intercourse. Clinical studies have proven sildenafil citrate to be effective at treating erectile issues related to various medical conditions or simply due to aging in men. Fildena 100 takes effect within 30-60 minutes and remains active in the body for around 4 hours.

As with any medication, it's important to note potential side effects of Fildena 100. Common mild side effects can include headache, facial flushing, indigestion, and muscle pain. Rare but more serious side effects are also possible, such as vision changes, ringing in the ears, and priapism (prolonged erection). As with Viagra and other ED drugs, Fildena 100 should not be taken with certain medications or supplements and requires a prescription from a doctor.
