Levitra Oral Jelly

Levitra Oral Jelly is a powerful medicine to treat erectile dysfunction. It works only if there is sexual stimulation. Sexual arousal releases nitric oxide from the nerves' endings of the cavernous bodies of the penis and activates guanylate cyclase enzyme. Guanylate cyclase in its turn is responsible for production of cyclic guanosine monophosphate (cGMP). Due to cGMP the blood vessels supplying the penis with blood widen and relax. Levitra prevents phosphodiesterase-5 enzyme from destroying cGMP and in this way helps to support blood flow to the penis. The recommended dose of Levitra Oral Jelly contains 20 mg of Vardenafil, it is available in a pack of sachet. Take it an hour before intercourse. In case of adverse effects it is recommended to reduce the dose to 5 mg daily. Do not exceed the recommended dose.

Levitra Oral Jelly is not recommended in patients who have a stroke or heart failure, or a heart attack in history and especially within last six month. Before using Levitra inform your doctor if you have serious renal impairment, a bleeding disorder, stomach ulcerations, or an inherited retinal disorder such as retinitis pigmentosa, allergic reaction to this medicine or any other medicines, deformation of the penis such as angulation, cavernous fibrosis (Peyronie's disease), as well as in diseases that contribute to the development of priapism (sickle-cell anemia, multiple myeloma, leukemia, or leukemia).

Levitra Oral Jelly cannot be prescribed in patients who are hypersensitive to its ingredients, ones treated with organic nitrates. Use in individuals who have not reached the age of 16 y.o. is contraindicated. Concomitant use of HIV protease inhibitors such as indinavir and ritonavir with Levitra Jelly is prohibited.

Metabolism of Levitra Oral Jelly is inhibited by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir). Levitra also reduces the blood concentration of ritonavir and indinavir. Chest pain may become more acute in patients treated with nitrates as the medication increases heart rate and lowers blood pressure. Levitra is able to exaggerate the blood pressure lowering effects of alpha-blocking drugs (terazosin or Hytrin). Levitra never should be administered in patients who are treated with organic nitrates.
