Fildena 150 is a medication used to treat erectile dysfunction (ED) in men. It contains a high dose of sildenafil citrate, which helps increase blood flow to the penis. This enables a man to achieve and maintain an erection when sexually aroused. It does not cause an erection on its own—sexual stimulation is required.

Sildenafil belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing the muscles and blood vessels in the penile area, improving blood circulation, and allowing for a firmer, more sustained erection.

Fildena 150 usually starts working within 30 to 60 minutes after being taken orally and can remain effective for 4 to 6 hours. It's a strong dose, often prescribed when lower doses have not produced the desired effect.

Because it's a high-strength tablet, Fildena should only be used under medical supervision. Taking too much can increase the risk of side effects such as headaches, flushing, dizziness, nasal congestion, and upset stomach.
