Uses
Penile erection during sexual stimulation is basically caused by increased penile blood flow. This in turn results in the relaxation of penile arteries and smooth muscle. This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells. This initiates the synthesis of cGMP and cyclic GMP causes increased blood flow into the corpus cavernosum. This subsequently results in sexual stimulus reaction and ensures a great and the desired love-making experience sought.

Dosage
The normal starting dose is 10 mg, which is roughly equivalent to 50 mg of viagra. Vardenafil or levitra should be taken approximately 25-60 minutes prior to sexual activity, with a maximum dose frequency of a tablet per day.

Side effects
The common and clinically proven vardenafil or levitra's side effects include nausea, abdominal pain, back pain, photosensitivity, sometimes reported abnormal vision, facial oedema, hypertension and palpitation, rash and an itch.

The use of products containing vardenafil or levitra has also been observed to have some serious side-effects like heart attacks. In rare cases, the use of vardenafil or levitra could also result in penile tissue damage.

Drug precautions
Levitra or vardenafil should not be used by individuals who are taking any kind of nitrate medication. The combination of the two products could result in the development of potentially life-threatening low blood pressure.
The more common adverse drug reactions or clinical ADRs are as just like those in the case of other PDE5 inhibitors like cialis and viagra.

Overdose
In case of an overdose of the drug, you should seek medical assistance immediately.

Missed dose
Levitra is taken only when needed so you can't miss a dose.

Storage
Medication should be stored in a cool, dry place.
