Viagra
Viagra (sildenafil) is a phosphodiesterase inhibitor that treats impotence by relaxing certain muscles and allowing for more blood flow into the tissues of the penis. It also prevents the blood from going back too soon, therefore providing for several hours of durability. For maximum effects you will need to take this drug about an hour before you are planning to have sex – and you will get up to 5 hours of efficiency. During this period you can attempt having sex and be sure that your erection will be hard enough to have sex, although Viagra is most efficient if taken soon after it becomes effective (i.e. after one hour from the moment you took it). Viagra is supposed to be taken while without the tablet being chewed or crushed, with a full glass of water, and not more often than every 24 hours. Taking Viagra with some foods that are high in fat may slow down the absorption of this drug and delay the effects of Viagra that you probably expect. You need to be aware of the fact some mild and serious side effects are possible. Mild side effects are usually short-lived and tend to go away on their own without any need for you to interfere and treat them in any way. The following symptoms are considered to be mild: memory problems, upset stomach, headache, warmth or redness in your face or chest, stuffy nose, and back pain. More serious side effects are not going to disappear on their own and if you do not treat them timely and properly they may get worse and affect your health and wellbeing. Make sure you report to your health care provider any of the following serious side effects in case you have them: general ill feeling, nausea, chest pain, sudden hearing loss, lightheadedness, sudden vision loss, irregular heartbeat, prolonged penis erection (priapism), swelling, shortness of breath, and sweating. Always observe the dose you are prescribed and talk to your doctor if you think your dose is inefficient. Some health conditions you have or used to have can be also important in determining the dose. They can also help your doctor to determine how much your dose can be increased if thee is such a necessity. Make sure you report the fact of having any of the following: irregular heartbeat, chest pain, stomach ulcer, bleeding disorder, diabetes, high cholesterol, stroke, blood circulation problems, high or low blood pressure, pulmonary veno-occlusive disease, blood cell problems, heart attack, heart, kidney or liver disease.
