Levitra (vardenafil) is a prescription drug often used by people diagnosed with erectile dysfunction. This medicine has been approved by FDA and is safe to use. Your doctor needs to know as much as possible about any other drugs you are using at the moment. This is important because there are a number of medicines that can decrease, increase or alter the effects of Levitra, which means there may be a few unpleasant surprises for you if you decide to go on with the treatment taking Levitra with any of the following medicines: danazol, antifungals, erythromycin, paroxetine, cyclosporine, phenytoin, dexamethasone, metronidazole, other erectile dysfunction drugs, fluoxetine, high blood pressure medications, disopyramide, clarithromycin, rifampin, amiodarone, drugs for isoniazid, irregular heartbeat treatment, cimetidine, nefazodone, rifabutin, efavirenz, sertraline, phenobarbital, HIV protease inhibitors, aprepitant, carbamazepine, alpha blockers, or quinidine. Although your health care provider may have slightly different recommendations for you, the usual routine involves taking Levitra 60 minutes before planned sex. Once you have felt the effects of this medicine they are likely to last for up to 5 hours, and you can have sex at any point during this time. However, remember that this period may slightly differ depending on your age and health condition, so it's best to have sex an hour after you have taken the dosage to make sure you achieve great performance.
