Is there any food or drinks I should avoid while taking sildenafil?

If possible, avoid grapefruit (juice) and excessive alcohol intake while taking sildenafil. Grapefruit (juice) might increase concentration of the sildenafil in your body, resulting in a higher chance of experiencing unwanted side effects. Drinking lots of alcohol may make it harder to get an erection and add on further to dizziness. Instead, here are some foods that you should consider eating to solidify your erection.
