Vardenafil inhibits phosphodiesterase type 5 (PDE5). PDE5 normally breaks down cyclic guanosine monophosphate (cGMP), a substance involved in blood-vessel relaxation.
By inhibiting PDE5, Vardenafil supports the action of cGMP and helps certain blood vessels relax, supporting increased blood flow during sexual stimulation.
Note: Sexual stimulation is generally required for the medicine to produce its intended effect.
Source information describes Levitra as having a relatively rapid onset, with effects often beginning within approximately 15–30 minutes. Duration may extend for several hours, although individual responses can vary.
Vardenafil may be less affected by food than some other PDE5 inhibitors, but high-calorie or high-fat meals may still delay absorption in some individuals.
Alcohol may increase dizziness or low blood pressure. Follow professional medical guidance regarding food and alcohol use.
Possible side effects may include:
Seek urgent medical attention for serious symptoms such as chest pain, fainting, sudden severe vision changes, or an erection that lasts unusually long.
Speak with a qualified healthcare professional before using Vardenafil if you have:
| Medicine / Substance | Important Information |

| Certain CYP3A4 inhibitors | May increase Vardenafil concentration and potentially increase side effects. |
| Blood-pressure medicines | May increase the risk of dizziness or low blood pressure. |
| Grapefruit products | May affect medicine metabolism and potentially increase Vardenafil levels. |
