Fildena 100mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is the same ingredient found in Viagra. Sildenafil citrate helps increase blood flow to the penis, allowing men to achieve and maintain an erection when sexually stimulated. Fildena 100, like other medications of its kind, should be taken under the guidance of a healthcare professional. It's essential to follow the prescribed dosage and instructions to ensure safety and effectiveness. Common side effects may include headache, flushing, upset stomach, and nasal congestion. It's important to note that Fildena 100 is a prescription medication, and you should not use it without consulting a healthcare provider, as they can assess whether it's suitable for your specific health needs and provide guidance on its use. Additionally, always buy medications from a reputable source and avoid purchasing from unverified online sources to ensure product quality and safety.
