Fildena 150 is a medication that contains 150 mg of sildenafil citrate, which is a phosphodiesterase type 5 (PDE-5) inhibitor. It is commonly prescribed to treat erectile dysfunction (ED) in men. Sildenafil works by increasing blood flow to the penis, helping men achieve and sustain an erection during sexual stimulation. As with any medication, it's crucial to use Fildena 150 under the supervision of a healthcare professional, who can provide guidance on proper dosage, potential side effects, and any interactions with other medications.
