Suhagra Force 50 mg, which contains sildenafil (the active ingredient in Viagra) and dapoxetine, typically begins to work within 30 to 60 minutes after taking it. The effects of sildenafil (for erectile dysfunction) generally last for around 4 to 6 hours, while dapoxetine (for premature ejaculation) may take effect more quickly, usually helping with control for about 1 to 2 hours.

For optimal results, it's recommended to take the medication about 1 hour before sexual activity, and it should be taken on an empty stomach or with a light meal, as a heavy or fatty meal can delay its action.
