Viagra

Viagra is the brand name of a medicine containing the active ingredient sildenafil, which is used to treat erectile dysfunction. It supports blood flow to the penis and can therefore help achieve and maintain an erection. The effect only occurs with sexual arousal; Viagra is not an aphrodisiac and does not automatically increase sexual desire.

The medicine is prescription-only and can cause side effects as well as dangerous interactions, especially with nitrate-containing medications and certain cardiovascular conditions. The stated success rate is not universally applicable and depends on the cause, dosage, and individual situation. It should therefore only be taken after medical advice, especially in the presence of pre-existing conditions, blood pressure issues, or other medications.
