Levitra

Levitra (vardenafil) is an anti-impotence medicine. If you are allergic to vardenafil or any other medicines of the kind (PDE5 inhibitors) you are not supposed to be taking this medicine, as otherwise serious health effects are possible, and you may get hives, rash, difficulty breathing and a number of other symptoms that are supposed to be reported directly to your health care provider. You are not supposed to be taking this drug after such a reaction until your doctor tells you it's ok. Levitra is supposed to be taken about an hour before having sex, and will provide you with up to 5 hours of effectiveness. Sexual stimulation is required for this medicine to work properly, although patients report it’s a lot easier to get sexually excited after taking this drug. You need to be aware of the fact each tablet of Levitra also contains inactive ingredients that you may theoretically be allergic to as well. A tablet of Levitra may contain the following inactive ingredients: red ferric oxide, polyethylene glycol, hypromellose, crospovidone, colloidal silicon dioxide, magnesium stearate, yellow ferric oxide, titanium dioxide, and microcrystalline cellulose. Do not start taking any drugs while on Levitra unless you know for sure they are unlikely to interact with this medicine. The following medicines are supposed to be discussed with your doctor before you start the treatment: rifabutin, erectile dysfunction medicines, lovastatin, high blood pressure medications, carbamazepine, delavirdine, isoniazid, HIV protease inhibitors, quinidine, clarithromycin, antifungals, efavirenz, phenytoin, paroxetine, cimetidine, irregular heartbeat drugs, erythromycin, amiodarone, metronidazole, alpha blockers, and phenobarbital. Never combine nitrate-based drugs (often prescribed for the treatment of chest pain) with Levitra, as the consequences can be very serious. The combination of Levitra and a nitrate-based drug, no matter which form it comes in, can significantly lower your blood pressure and lead to fainting, coma and even death. Although an overdose of Levitra is not expected to produce any health effects that are life-threatening, some of them can be quite serious – such as priapism, for instance. This side effect is rare but possible and can be described as a prolonged (over 4 hours) erection that does not go away and can damage the tissue of the penis permanently. If you suspect priapism - seek emergency medical help.
