Kamagra Oral Jelly is a sildenafil citrate-based medicine used to treat erectile dysfunction (ED) in adult men. It works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. The jelly format may be convenient for men who have difficulty swallowing tablets. It should be used only as directed by a qualified healthcare professional, particularly because it can interact with nitrate medicines and may cause side effects such as headache, flushing, dizziness, or indigestion.
