Viagra Without Prescriptions:
Viagra (sildenafil citrate) can be used by male patients diagnosed with ED. ED is a condition that can be described as an inability of a male to get an erection that would be hard enough to penetrate. Viagra is not supposed to be taken more often than every 24 hours as an overdose is possible. The following are possible symptoms of an overdose that you will need to report to your local emergency center: lightheadedness, fainting, nausea, and irregular heartbeat. Both mild and more serious side effects are possible. Mild side effect, such as stuffy nose, memory problems, back pain, upset stomach, warmth or redness in your face, neck, and headache, are common but tend to go away on their own. More serious side effects will need to be reported to your health care provider to prevent them from getting even worse. These include irregular heartbeat, sweating, general ill feeling, shortness of breath, swelling in your hands, vision changes, sudden vision loss, nausea, chest pain, sudden hearing loss, feeling light-headed, or ringing in your ears. Tell your doctor about any diseases you have or drugs you are using, as that may affect the dose of Viagra you are prescribed or require additional tests to establish the safety of using this drug.
