Priapism/cardiovasc.: Main concerns are priapism, which is n erection lasting >4hours. Needs to be treated promptly to avoid permanent erectile dysfunction. Of concern if subject has significant arteriosclerosis putting him at risk for stroke + stroke-like symptoms of loss of vision, hearing and severe headaches. Severe allergic can also occur after repeated usage. Fortunately severe side-effects or problems are rare.

Concerns : The main side effects with any pde-5 inhibitor (viagra, levitra, (vardenafil) cialis) include possible sudden drops in blood pressure, sinus congestion and/or headaches from vasodilation, and prolonged erection (priapism). Also, you need to review your entire medication list with the doctor, some medications make it dangerous to take along with a pde-5 inhibitor.
Dr. Richard Sarle

Cardiac history: If you take medicine like nitro for chest pain viagra (sildenafil) can cause an unsafe drop in blood pressure or even death. I encourage pts with a cardiac history to be cleared by their cardiologist before using viagra (sildenafil). Also so other medications can't be used with viagra (sildenafil), so a good drug interaction check is important.

GoodRx: Check out www.goodrx.com - depending on your zip code and what pharmacies you have around you, you may be able to find viagra fairly cheap with the coupons/discounts offered there. For example, near me, one can get 10 tablets of 50mg viagra for $15.40, as opposed to the usual retail price of $346-$644 for the same dosage/amount. This wasn't exactly your question, but I thought it might help.

How soon does viagra (sildenafil) begin to work?

About 20 minutes.: Viagra (sildenafil) does not begin to work immediately, it has to be absorbed from your stomach, enter the blood stream and reach the penile blood vessels. This usually takes 20 - 30 minutes.

Good start: Viagra (sildenafil) is one of several fda-approved drugs to treat erectile dysfunction (ed). The first step is to discuss your ed with your doctor, as it may be a clue to other health issues. A drug like the "little blue pill" might be a good first treatment, as long as you're healthy enough for sex and don't take nitroglycerine. Ten-hut, soldier!
