Special instructions

Elderly patients (over the age of 65):

Dose adjustment for elderly patients is not required.

Children (under the age of 18):

Levitra is not indicated for patients of this age group.

Liver function violation:

Patients with minor hepatic impairment changes require a dosage adjustment. Patients with moderate impairment (stage B) of the liver are recommended to start with the initial dose of 5 mg/day. Further, depending on the efficiency and tolerability of the treatment, the dose can be increased to the maximum dose for this group of patients – 10 mg.

Impaired renal function:

Dose adjustment is required in patients with small (Cl creatinine> 50-80 ml / min), moderate (Cl creatinine> 30-50 ml / min) and severe (Cl creatinine Patients taking CYP3A4 inhibitors: You may require a dose adjustment, if you are taking specific inhibitors of cytochrome P450 (CYP) 3A4 with moderate or strong action, such as ketoconazole, itraconazole, erythromycin, clarithromycin, ritonavir, and indinavir.

In a joint application of Levitra with CYP3A4 inhibitors ketoconazole or itraconazole, their dose should not exceed 200 mg per day. If the dose of ketoconazole or itraconazole exceeds 200 mg per day, the ED drug should not be used.

In a joint application with inhibitors of CYP3A4, erythromycin or clarithromycin, the dose of Levitra should not exceed 5 mg per day – otherwise man may experience side effects.

This drug is cotraindicated to men taking HIV protease inhibitors such as indinavir and ritonavir.

Patients taking alpha-blockers:

Due to the vasodilating effect of alpha-blockers and vardenafil, the co-administration of these tablets may cause symptomatic hypotension in some patients. Joint administration can be started only if the patient has a stable condition in the treatment with alpha-blockers.

Levitra may be taken at any time with tamsulosin or alfuzosin. In the case of a joint appliance of this ED drug with terazosin and other alpha-blockers, man should observe the necessary interval between the doses of vardenafil and alpha-blockers.

Patients who are already taking the optimal dose, should start the treatment with the lowest dose of alpha-blockers. The gradual increase in the dose of alpha-blocker may be followed by a subsequent decrease of blood pressure in patients taking PDE5 inhibitors, including Levitra from My Canadian Pharmacy.

Overdose

A reserch of healthy volunteers tested Vardenafil single doses in the amount of 120 mg per day. Single doses of 80 mg and multiple doses up to 40 mg taken once daily within 4 weeks were well tolerated, no serious adverse reactions were observed.

However, Levitra 40 mg 2 times a day provoked pain in the muscular and nervous systems.

In case of overdose, man requires a standard maintenance therapy. Vardenafil is highly bound to plasma proteins, only a small amount of the drug is excreted through the kidneys, so, dialysis efficiency is unlikely.
