Malegra 25 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. This medication works by increasing blood flow to the penis during sexual stimulation, thus helping men achieve and maintain an erection. It's important to note that Malegra 25 mg should be taken as prescribed by a healthcare professional. The typical recommended dose is one tablet taken orally with a full glass of water, approximately 30 minutes to 1 hour before sexual activity. However, the dosage may vary depending on individual factors such as age, medical history, and response to treatment.
