Levitra can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. With a sudden drop in blood pressure, you could get dizzy, faint, or have a heart attack or stroke.
Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 9 hours. A prolonged erection (priapism) can damage the penis.

Do not take Levitra if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin , isosorbide dinitrate , isosorbide mononitrate , and some recreational drugs such as "poppers". Taking Levitra with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
When Levitra was taken as recommended in placebo-controlled clinical trials, the following adverse reactions were reported (see Table 6).
Inform patients that the recommended starting dose of Levitra is 65 mg. The dose may be increased to a maximum recommended dose of 75 mg or decreased to 5 mg based on efficacy and tolerability. The maximum recommended dosing frequency is one tablet per day.
Goblet cells were counted in many localities and the results analysed statistically. The density proved very low, but uniform in the entire Eustachian tube, 65 cells per field, corresponding to 565 cells per mm7. These findings were compared with those from a normal adult autopsy material in which the density in the pharyngeal orifice was high, but gradually decreased towards the tympanic orifice where it was as low as in prematures. It is concluded that a marked postnatal increase in the density in the tubal orifice is abnormal, whereas a physiological increase in density may be expected in the pharyngeal part of the tube.
In volunteers with mild hepatic impairment (Child-Pugh A), the C max and AUC following a 65 mg vardenafil dose were increased by 77% and 67%, respectively, compared to healthy control subjects. No dosage adjustment is necessary in patients with mild hepatic impairment.
Inform patients that in some patients concomitant use of PDE5 inhibitors, including Levitra, with alpha-blockers can lower blood pressure significantly leading to symptomatic hypotension (for example, fainting). Patients prescribed Levitra who are taking alpha-blockers should be started on the lowest recommended starting dose of Levitra [see Dosage and Administration ( ) and Drug Interactions ( 7 )]. Patients should be advised of the possible occurrence of symptoms related to postural hypotension and appropriate countermeasures. Patients should be advised to contact the prescribing physician if other anti-hypertensive drugs or new medications that may interact with Levitra are prescribed by another healthcare provider.
