Order Cheap Levitra online from Canada! Levitra (Vardenafil) belongs to the class of medications called cyclic GMP-specific phosphodiesterase type 5 inhibitors. Levitra works by increasing smooth muscle relaxation and allowing blood to flow into the penis. Levitra (Vardenafil) is used for the treatment of erectile dysfunction (impotence). It helps a man achieve and keep an erection when he is sexually stimulated. Levitra (Vardenafil) does not increase sex drive. The usual starting dose of Levitra in Canada is 10mg. Your doctor may recommend a dose as low as 5 mg or as high as 20 mg. Swallow the tablet of Levitra whole with water. Levitra may be taken with or with out food. This medication should be taken 25 to 60 minutes before sexual activity. Levitra will usually require 15 to 60 minutes to take effect and may last for four to five hours. Do not take Levitra more than once a day. Because alcohol can make it more difficult to get an erection, do not drink large amounts of alcohol with Levitra or before sexual activity. Moderate amounts of alcohol (two drinks for a 70-kg person) will not interfere with the medication. Levitra (Vardenafil) should not be taken by anyone who is taking any medication that contains nitrates (e.g., amyl nitrate poppers, isosorbide mononitrate, isorbide dinitrate, nitroglycerin), is taking indinavir or ritonavir (for HIV infection), is taking ketoconazole or itraconazole (for fungal infections), is allergic to vardenafil or any other ingredients of Levitra. Nitrates are found in medications that are used to treat angina (chest pain). If you are not sure if you are taking nitrates, ask your doctor or pharmacist. Nitrates must NOT be taken by anyone who is using vardenafil because they can cause your blood pressure to drop very low. This may cause dizziness, fainting, heart attack, or stroke. Side effects of Levitra listed below are not experienced by everyone who takes Levitra. If you are concerned about side effects, discuss the risks and benefits with your doctor. Some common side effects of Levitra include headaches, or flushing (warm or burning feeling, usually in the face). Less common side effects of Levitra include indigestion and stuffy nose. Rare side effects of Levitra include abnormal vision (e.g., decreased vision, blurry vision, increased sensitivity to light, changes in the ability to tell the difference between blue and green). You should contact your doctor if you have an erection that lasts longer than four hours (this could permanently damage your penile tissue), you have a heart condition and develop chest pains, an irregular heartbeat, or shortness of breath when starting sexual activity or if you have an allergic reaction (e.g., rash; itching; shortness of breath; swollen face, lips, or throat). Grapefruit juice can increase the amount of vardenafil in your bloodstream. Do not drink grapefruit juice when taking Levitra. An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
