One of the most recognisable ED medications and often the first treatment people hear about.
Viagra is presented here as a familiar tablet-based option, available in different strengths and typically used before sexual activity.
Probably the best known tablet for erectile dysfunction, it is made by Pfizer and comes in blue tablet form in strengths of 25mg, 50mg and 100mg.
As with all medication, it is advised that you read the instructions before use. The original site copy notes that taking more than directed can easily cause problems.
On average, it will keep me hard for about 30 minutes, but the wider point is to work with your GP or consultant on what is realistic and safe for you.
You can also get sildenafil citrate in an oral jelly form, made by Scilla Biotechnologies.

Recreational drugs can have a negative effect on the performance of sildenafil citrate.
