Marketed under the brand name Viagra, sildenafil citrate is one of the most popular medications used in the treatment of erectile dysfunction in men. This famous blue prescription pill belongs to a class of drugs known as PDE5 inhibitors and works by restricting the action of PDE5, a chemical that inhibits the flow of blood to your penis and prevents a satisfactory erection from taking place. Viagra eases blood flow to the penis and enables you to have a complete erection. It is important to remember that Viagra does not work as an aphrodisiac and cannot be effective in the absence of external sexual stimulation. The effects of this blue pill for impotence can be experienced in about half an hour and the effects last for about 4 hours.
Precautions to be taken with Viagra
Viagra is prohibited for people who are already taking medications containing nitrates for heart trouble or chest pain. Medications containing isosorbide dinitrate, nitroglycerin, and isosorbide mononitrate as well as recreational drugs such as amyl nitrite or nitrates are not supposed to be combined with sildenafil citrate. This is because combining nitrate medication with Viagra can cause a sudden and sometimes fatal drop in blood pressure and lead to a stroke, fainting spells or heart attacks. Call your healthcare provider right away if you ever experience nausea, dizziness, numbness, pain or tingling sensations in your jaw, neck, arms or chest during sexual activity after taking Viagra. Your body could be reacting extremely negatively to this impotence medication.
Viagra is not recommended to be taken more than once in 24 hours. It is essential that you allow an interval of 24 hours between doses. If you experience a painful or prolonged erection that lasts for more than 4 hours (priapism), get emergency medical help immediately to avoid damaging your penis permanently. Viagra is known to restrict the flow of blood to the optic nerve, sometimes resulting in sudden loss of vision. This, however, is an extremely rare side effect of Viagra that largely affects people who have had certain pre-existing conditions such as diabetes, heart disease, high cholesterol, high blood pressure or optical problems. These side effects can also affect heavy smokers or those over the age of 50. Although the links between these effects and Viagra use have not been proved, you should stop taking the medication if you experience any of them.
It is important to discuss your medical history with your doctor before commencing Viagra treatment. Your doctor needs to know if you are allergic to any of the drugs or have ever suffered from any kind of heart disease, including heart rhythm problems, heart attack, stroke or congestive heart failure. People suffering from serious health conditions such as low or high blood pressure, liver disease, coronary artery disease, kidney problems, bleeding disorders such as hemophilia, blood cell disorders such as multiple myeloma, leukemia or sickle cell anemia, stomach ulcers, retinitis pigmentosa (a genetic eye condition), or a penile deformity such as Peyronie's disease also need to consult their doctor before using Viagra. It is not recommended for you if you have been advised to abstain from sexual intercourse for medical reasons. Ask your doctor if you require special tests or dose adjustment for taking Viagra safely.
High intake of alcohol can interfere with the Effects of Viagra and have a negative impact on your ability to have a satisfactory erection. Avoid drinking before or immediately after taking Viagra. Food intake does not have a significant impact on the action of Viagra. However, fatty foods such as fries or cheeseburgers can slow down the absorption of Viagra in your body. Have a light meal before taking Viagra or give your body more time to absorb high calorie foods. Follow your doctor's instructions as closely as possible for best Viagra results.
