Fildena Professional is primarily used to treat erectile dysfunction (ED) in men. Fildena Professional contains sildenafil citrate in a sublingual form, which allows it to dissolve under the tongue for faster absorption into the bloodstream. This medication works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain a firm erection. Fildena Professional is often preferred by those who need quicker results due to its rapid onset of action. It is not a cure for ED or a hormone-based treatment, and it only works when there is sexual arousal. It should be taken as prescribed by a healthcare provider.
