Levitra (vardenafil) is a treatment recommended for patients who have been diagnosed with erectile dysfunction and are not able to perform sexually, which results in problems in their personal life. If your health care provider specifically instructed you to refrain from sex activity make sure you observe these recommendations and do not have sex after taking Levitra to avoid putting too much strain on your heart. You need to know about the possibility of developing certain serious side effects of Levitra, although these are rare: priapism (prolonged and painful erection), hoarseness, rash and hives, swelling in your limbs, ringing in the ears, loss of vision or hearing, dizziness, trouble breathing, blurred vision, and some other symptoms that can be different for different patients.

Levitra remains efficient for up to 5 hours, but the effects can become less noticeable after a couple of hours from the moment you take it. If you are older than 65, have to take certain medications or have been diagnosed with some health conditions, the period of efficiency may be shorter for you. You need to discuss such important factors as age, health condition and other medications you are on, to make sure you benefit from the treatment without any of the side effects sometimes associated with Levitra. Before you are prescribed any new medication you also need to tell your doctor about taking Levitra as your dosage of the new drug may be decreased, increased or other changes can be made to make sure you benefit from both methods of treatment.
