Levitra causes erections only during sexual excitement. It does not work in the absence of arousal and does not increase sexual desire.



Take one Levitra tablet about one hour before sexual activity, with or without food.

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Levitra.

Do not take Levitra if you are taking any nitrate-based drug, including nitroglycerin patches (Nitro-Dur, Transderm-Nitro), nitroglycerin ointment (Nitro-Bid, Nitrol), nitroglycerin pills (Nitro-Bid, Nitrostat), and isosorbide pills (Dilatrate-SR, Isordil, Sorbitrate). This also includes street drugs known as "poppers," including amyl nitrate and butyl nitrate.

Combining Levitra with any of these drugs can cause a dangerous drop in blood pressure.

Likewise, do not take Levitra with certain blood pressure and prostate drugs known as alpha-blockers, including Cardura (doxazosin), Flomax (tamsulosin), Hytrin (terazosin), Minipress (prazosin), and Uroxatral (alfuzosin).

If Levitra gives you an allergic reaction, do not use it again. Levitra should not be used by women.

Side effects may include:

Indigestion, flu-like symptoms, flushing, headache, runny nose, sinus inflammation.

If you have heart problems severe enough to make sexual activity a danger, you should avoid using Levitra. If you take Levitra and develop cardiac symptoms (for example, dizziness, nausea, and chest pain) during sexual activity, do not continue.

Be equally cautious if you have severe high or low blood pressure, heartbeat irregularities, or unstable angina (crushing heart pain that occurs at any time). If you develop angina after taking Levitra, seek medical attention immediately.

If you have severe kidney or liver problems, a bleeding disorder, stomach ulcer, or an inherited retinal disorder such as retinitis pigmentosa, use Levitra with caution. Its safety under these circumstances has not yet been studied.

Rare cases of prolonged and sometimes painful erections (known as priapism) have been reported with Levitra. If you develop an erection that lasts more than 4 hours, seek medical treatment immediately. Otherwise, permanent damage and impotence could result.

If you have a condition that might result in long-lasting erections, such as sickle cell anemia, multiple myeloma (a disease of the bone marrow), or leukemia, use Levitra with caution. Also use caution if you have a genital problem or deformity such as Peyronie's disease.
