For practical administration instructions see Timing of dosing. For safety and statutory information see Safety compliance checks before starting and UK regulatory and access information.
What happens and how this works
Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor group. Sexual stimulation triggers release of nitric oxide in penile tissue. Sildenafil inhibits PDE5, reducing the breakdown of cyclic GMP (cGMP). Elevated cGMP promotes relaxation of smooth muscle in the corpora cavernosa, allowing increased blood flow and enabling erection when sexual arousal is present. The medicine facilitates the natural erectile process; it does not cause spontaneous erections without stimulation.
How and when to dose
Usual practical advice:
- Timing: chew and swallow one tablet about 30 to 60 minutes before planned sexual activity for many users.
- Do not take more than a single dose within any 24 hour period.
- Food effects: a large or high fat meal can slow the onset of action and delay effect.
- Alcoholic drink: excess alcohol can reduce effectiveness and increase dizziness or other unwanted health consequences.
- Grapefruit: avoid grapefruit and grapefruit juice because they may increase blood levels of sildenafil.
If you have liver or kidney impairment, cardiovascular disease, or eye problems, consult a clinician or pharmacist before using sildenafil. See Drug engagement and communication potential and precautionary notes for medicines that affect sildenafil exposure.
