Do not take Cialis if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking Cialis with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack. If you become dizzy or nauseated during sexual activity, or if you have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of Cialis. Do not take this medication more than once a day. Allow 24 hours to pass between doses. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

Cialis vs. Cialis a Day

Like all erectile dysfunction drugs, Cialis is taken an hour prior to commencement of sexual activity. But with the approval of the small doses of the new drug Cialis-a-day this will change forever. Now with daily doses, men can achieve an erection whenever they want to have sex as the effect of Cialis is present in their body on a regular basis. As in the case of Cialis, Cialis-a-day will not have to be taken prior to every sexual activity. This affords you complete control, as well as normalcy.

With Viagra, you can discharge your seeds with the velocity of a rocket propeller in zero gravity. Viagra gives man an erection, second to none in vigor and energy, unparallel to any erection in terms of its sheer intensity. It is definitely a big hit with men, who go about copulating wildly and feverishly as if there is no tomorrow, caring not the ramifications their untamed actions can lead to. Men with a one night stand in mind sing the Viagra song. Relationships and emotional bonds are a far cry, entities totally alien to their very flirty existence. The Viagra anthem goes by the tune, hit when the iron (rod) is hot.

The second drug to be released on the market was Levitra. Levitra has a slight chemical compound difference that has been found to be more effective in hard to treat groups. Levitra takes around 45 minutes to take affect and unlike Viagra, eating and drinking do not affect the effectiveness except for highly fatty substances. Levitra is thought to have more potency, efficacy, and longer duration than Viagra. Levitras? side effects include headache, flushing, and stuffy or runny nose.

Cialis and drugs related to it like Viagra act by inhibiting an enzyme called phosphodiesterase type 5 which release Nitric Oxide from nerve endings and endothelium causing relaxation of smooth muscle and hence penile erection.
