Description
When a man becomes sexually aroused, blood flows into the
penis, causing it to expand and harden. Without good blood
flow, the penis cannot become erect or rigid. Levitra helps
increase the blood flow to the penis, allowing it to become erect
and rigid so that sexual intercourse is possible. The erection
should go away when the man has completed sexual activity.
Original uses (on-label)
Erectile dysfunction
Newly discovered uses (off-label)
Pulmonary hypertension
Potential side effects
The most common side effects are headache, flushing, stuffy or
runny nose, indigestion, upset stomach, or dizziness. Call your
doctor if you have a side effect that bothers you or that does not
go away. If you get an erection that lasts more than 4 hours, seek medical
attention right away.
Cautions
- Do not use this drugs in men for whom sexual activity has undue cardiac risk.
- Immediate medical attention should be sought if an erection lasts longer than 4 hours. A delay in treatment may cause penile tissue damage and permanent loss of potency.
Drug interactions
Before you decide to buy Levitra, tell your doctor and pharmacist about all prescription and over-the-counter medications you take.
Levitra should not be taken with certain medications. Do not take it if you take nitrates for heart disease, alpha-blockers to lower blood pressure (terazosin, tamsulosin, doxazosin mesylate, prazosin, alfuzosin), medicines that treat abnormal heartbeat (quinidine, procainamide, amiodarone, sotalol), ritonavir or indinavir, ketoconazole or itraconazole, or erythromycin. Do not buy vardenafil if you are already taking another medicine or treatment for erectile dysfunction.
Food interactions
Grapefruit juice. May be taken with or without food. Studies show that when Levitra and alcohol are taken together,
there is no adverse effect on heart rate or blood pressure. Alcohol, however, may decrease a man's ability to achieve an erection.

Special information
A study conducted in Germany examined its effect on pulmonary and systemic blood systems and gas exchange parameters in patients with pulmonary arterial hypertension (PAH).
Sixty PAH patients who underwent right heart catheterization (procedure to insert a thin plastic tube into an artery or vein in the arm or leg) received short-term nitric oxide inhalation and were subsequently given either sildenafil, vardenafil, or tadalafil.
All three drugs caused significant pulmonary vasorelaxation, with maximum effects being obtained after 40 to 45 minutes (vardenafil), 60 minutes (sildenafil), and 75 to 90 minutes (tadalafil).
Significant improvement in arterial oxygenation was only noted with sildenafil. Researchers assert that careful evaluation of each new drug, when being considered for PAH treatment, has to be undertaken.
Additionally, these drugs have the potential for significant drug interactions and should not be used if you are maintained on nitrates.
