Fildena 100mg is a medication used to treat erectile dysfunction in men. It contains the active ingredient sildenafil citrate, which helps increase blood flow to the penis, allowing a man to achieve and maintain an erection during sexual arousal. It's important to note that Fildena 100, like other medications containing sildenafil, should be used under the guidance of a healthcare professional, as it may have potential side effects and interactions with other drugs. It should only be taken as prescribed by a licensed medical practitioner.
