Special instructions

Prior to the appointment of Levitra (as well as other drugs used to treat erectile dysfunction), the doctor should evaluate the condition of the cardiovascular system, since there is a risk of developing complications from the heart during sexual activity.

Vardenafil has vasodilating properties, which can be accompanied by a slight or moderate decrease in blood pressure.

Patients with left ventricular outflow obstruction, for example, with aortic stenosis, idiopathic hypertrophic subaortic stenosis, may be sensitive to the action of vasodilators, including PDE5 inhibitors.

In men who are not shown sexual activity, due to concomitant action of levitra cardiovascular disease, drugs for the treatment of erectile dysfunction are not prescribed.

Since Levitra  at therapeutic doses (10 mg) causes prolongation of the QT interval, the drug should not be given to patients with congenital QT interval elongation and those taking antiarrhythmic drugs of class IA (quinidine, procainamide) or class III (amiodarone, sotalol).

The safety and effectiveness of vardenafil in combination with other drugs for the treatment of erectile dysfunction has not been studied, so their joint use is not recommended.

The safety of vardenafil has not been studied and its use is not recommended in the following groups of patients: severe liver dysfunction, end-stage renal disease requiring hemodialysis, arterial hypotension (systolic pressure at rest <90 mm Hg), recent stroke or myocardial infarction (within the last 6 months), action of levitraunstable angina, as well as hereditary degenerative diseases of the retina, for example, retinitis pigmentosa.

Against the background of taking Levitra  and other PDE5 inhibitors, cases of transient loss of vision and non-artery ischemic neuropathy of the optic nerve were recorded. In the event of sudden loss of vision, the patient should stop taking Levitra  and consult a doctor immediately.

Combined therapy with alpha-adrenoblockers and vardenafil may be accompanied by the development of arterial hypotension with a corresponding clinical picture, as these drugs have a vasodilating effect. The combined use of Levitra  and alpha-adrenoblockers is acceptable only if there are stable indices of BP against the action of levitra background of alpha-blockers, while Levitra  should be prescribed in the minimum recommended dose of 5 mg. Do not take Levitra  at the same time with alpha-adrenoblockers, with the exception of tamsulosin, which may coincide in time with the use of vardenafil. In the case of a selected dose of Levitra therapy with alpha-blockers should be started at the lowest dose. A gradual increase in the dose of alpha-blockers to patients receiving drugs from the group of PDE5 inhibitors may lead to a further decrease in blood pressure.

The dose of Levitra  should not exceed 5 mg when it is combined with erythromycin, ketoconazole, itraconazole. The dose of ketoconazole and itraconazole should not exceed 200 mg.
