Sildenafil is a highly effective treatment for erectile dysfunction. It's an excellent choice for men who want reliable erection support but don't want to pay for a famous brand name. Sildenafil is effective in 80% of men, while less than 2% of users report adverse effects.

Fatty foods can slow down the onset of the drug, meaning you might miss optimal timings. Remember, it's best if you take Sildenafil about an hour before sex to ensure that it’s fully absorbed.

We recommend that you try treatment eight different times before trying another ED treatment. This does not apply if you experience serious side effects, in which case you should stop immediately.
