01How the 2.5 mg tablet is used
For most patients, the recommended starting dose of LEVITRA is 10 mg, taken orally approximately 60 minutes before sexual activity. The maximum recommended dosing frequency is once per day. LEVITRA can be taken with or without food. Sexual stimulation is required for a response to treatment. Maximum plasma concentrations after a single 20 mg dose are usually reached between 30 minutes and 2 hours, with a median of 60 minutes. A 2.5 mg film-coated tablet is one labelled LEVITRA strength.
02The labelled QT stops
LEVITRA is contraindicated in patients with congenital QT prolongation. LEVITRA is contraindicated with Class IA (e.g. quinidine, procainamide) or Class III (e.g. amiodarone, sotalol) antiarrhythmics.
03Reactions reported at 2 percent or greater
LEVITRA was administered to over 4430 men (mean age 56, range 18-89 years) during controlled and uncontrolled clinical trials worldwide. Over 2200 patients were treated for 6 months or longer, and 880 patients were treated for at least 1 year. In placebo-controlled clinical trials, the discontinuation rate due to adverse events was 3.4% for LEVITRA compared to 1.1% for placebo.
Headache was reported in 15% of Levitra-treated patients and 4% on placebo in fixed and flexible-dose trials of 5 mg, 10 mg, or 20 mg. Flushing occurred in 11% versus 1%. Rhinitis occurred in 9% versus 3%. Dyspepsia occurred in 4% versus 1%. Sinusitis occurred in 3% versus 1%. Flu syndrome occurred in 3% versus 2%. Dizziness occurred in 2% versus 1%. Nausea occurred in 2% versus 1%.
04Organic nitrates on the Levitra label
Administration of LEVITRA with nitrates (either regularly and/or intermittently) and nitric oxide donors is contraindicated. Nitrates include nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and amyl nitrite.
In healthy middle-aged subjects, sublingual nitroglycerin 0.4 mg at 1 and 4 hours after vardenafil 20 mg still showed extra blood-pressure drop. Those extra effects were not seen when LEVITRA 20 mg was taken 24 hours before the nitroglycerin. A suitable time interval following LEVITRA dosing for the safe administration of nitrates has not been determined.
Do not combine LEVITRA with other PDE5 inhibitors.

Benoit El-Masri, Anjou asks
Is STAXYN the same product as film-coated 2.5 mg Levitra?
Reply from our reviewer
An orally disintegrating 10 mg vardenafil tablet is a different product. STAXYN is not interchangeable with film-coated Levitra. It provides higher systemic exposure compared to vardenafil 10 mg film-coated tablets. STAXYN should be taken orally, as needed, approximately 60 minutes before sexual activity. The maximum dosing frequency is one STAXYN tablet per day. STAXYN should be placed on the tongue, where it will disintegrate. It should be taken without liquid. Each STAXYN tablet contains 1.01 mg phenylalanine, which can be harmful to people who have phenylketonuria. Film-coated 2.5 mg LEVITRA is swallowed. Water is used with the coated tablet. If the prescription says film-coated 2.5 mg, fill film-coated 2.5 mg.
