Kamagra 100 mg normally begins working within 30 to 60 minutes of intake. Its key ingredient, sildenafil citrate, promotes blood flow to the penis, allowing men to develop and maintain a hard erection when sexually stimulated. To get the greatest results, take the tablet on an empty stomach with water, as heavy or fatty meals may delay its action. The medication's effects might last up to 4 to 6 hours, providing ample time for intimacy. It does, however, require sexual excitement to function properly. Before using any medication, always consult your doctor about the appropriate dosage and safety warnings.
