Malegra 100 mg is a generic medication containing sildenafil citrate, primarily used to treat erectile dysfunction (ED) in men. Manufactured by Sunrise Remedies Pvt. Ltd., it functions by inhibiting the enzyme phosphodiesterase type 5 (PDE5), thereby enhancing blood flow to the penis during sexual arousal, leading to improved erectile function.

For optimal results, take one tablet approximately 30 to 60 minutes before anticipated sexual activity. The Malegra 100 mg medication remains effective for about 4 to 6 hours. It can be consumed with or without food; however, avoid high-fat meals, alcohol, and grapefruit juice, as they may interfere with its effectiveness. 

Common side effects include headaches, dizziness, flushing, nasal congestion, and upset stomach. Serious adverse effects, though rare, may involve prolonged erections lasting more than 4 hours, chest pain, or sudden vision or hearing loss. Seek immediate medical attention if any severe reactions occur.
