Fildena 25 mg is a medication commonly used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil citrate, a drug that belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by relaxing the blood vessels in the penis, which increases blood flow during sexual stimulation and helps men achieve and maintain an erection. Certain patients should exercise caution or avoid Fildena, including those with heart disease, low blood pressure, liver or kidney problems, or those taking nitrate medications, as combining these can lead to dangerous drops in blood pressure. https://www.genericday.com/fildena-25-mg.html
