Kamagra 100 is a drug often used to treat erectile dysfunction, and it usually starts working after 30 to 60 minutes of administration. The key ingredient, sildenafil citrate, improves blood flow to the penis during sexual stimulation, assisting in the production and maintenance of an erection. It is best taken on an empty stomach, as heavy or fatty meals can delay its effects.

The drug's effects normally last 4 to 6 hours, however this varies from person to person based on metabolism, age, and general health. Before using this product, users should follow the dose directions and speak with a healthcare expert.
