Levitra® (Vardenafil HCL) is an oral therapy for the treatment of erectile dysfunction (impotence). This monohydrochloride salt of vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Levitra or Vardenafil work by relaxing muscles and increasing blood flow to particular areas of the body. Vardenafil may also be used for purposes other than those listed in this drug information guide.
Vardenafil is used to treat male sexual function problems (impotence or erectile dysfunction). This drug is not indicated for use in women. Seek immediate medical help if any of these occurs: Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); back or muscle pain; chest pain; fainting; prolonged, painful erection; ringing in the ears; severe or persistent dizziness; severe or persistent vision changes; sudden hearing loss.
For most patients, the recommended starting dose of Levitra or Vardenafil is 10 mg, taken orally approximately 1 hour before sexual activity. The dose may be increased to a maximum recommended dose of 20 mg or decreased to 5 mg based on efficacy and side effects. The maximum recommended dosing frequency is once per day. Levitra or Vardenafil can be taken with or without food. Sexual stimulation is required for a response to treatment. A starting dose of 5 mg Vardenafil should be considered in patients above 65 years of age.
Common side effects of Levitra or Vardenafil are dizziness, flushing, headache, heartburn, stuffy or runny nose and upset stomach. A serious allergic reaction to this Vardenafil is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching, unusual swelling, severe dizziness, trouble breathing.
Inform your doctor if you are taking any other medicines, especially any of the these: Alpha-blockers (eg, doxazosin), medicines for high blood pressure, nitrates (eg, isosorbide, nitroglycerin), or nitroprusside because severe low blood pressure with dizziness, lightheadedness, and fainting may occur Certain antiarrhythmics (eg, quinidine, amiodarone) because the risk of irregular heartbeat may be increased Azole antifungals (eg, itraconazole), HIV protease inhibitors (eg, ritonavir), macrolide antibiotics (eg, erythromycin), or telithromycin because they may increase the risk of Levitra 's side effects. Rifampin because it may decrease Levitra's effectiveness.
Symptoms of overdose may include back or muscle pain, chest pain, fainting, prolonged erection, severe dizziness, severe or persistent vision changes.
Administration of LEVITRA with nitrates (either regularly and/or intermittently) and nitric oxide donors is contraindicated
Tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies, before taking vardenafil.
