Sildenafil Oral Jelly 100mg is primarily used to treat erectile dysfunction (ED). It contains sildenafil citrate, which helps increase blood flow to the penis, facilitating an erection when there is sexual stimulation. The jelly form is often preferred for its ease of use and faster absorption compared to tablets. Typically taken about 30 minutes to an hour before sexual activity. It's usually recommended not to exceed one dose in a 24-hour period.
