Viagra is a medication that is used for the treatment of erectile dysfunction. Its active ingredient is sildenafil, which is also used in several other erectile dysfunction medications as well as medications to treat pulmonary arterial hypertension, such as Revatio. Viagra works by relaxing the muscles of the penis in order to increase blood flow to that area.
Viagra is an over the counter medication and should only be taken on an as needed basis. It is suggested that it be taken anywhere from 30 minutes to an hour before having sexual intercourse, although it may be taken up to 4 hours before partaking in sexual activities. Viagra should not be taken more than once in a 24 hour time frame.
The suggested dosage form to be taken of Viagra is 50 mg, although 25 to 100 mg of the medication can be taken once a day, as needed. Be mindful that while Viagra is used for the treatment of erectile dysfunction, it is not meant to be a cure for the disorder.
If taking other medications to treat erectile dysfunction, such as avanafil, tadalafil, or vardenafil, do not take Viagra. Before taking Viagra let your doctor know about any current medications you are taking such as antibiotics, antifungal medications, high blood pressure medications, medications to treat HIV/AIDS, or medications used to treat prostate disorders. Also speak with your doctor if you are currently taking riociguat.
Do not take Viagra if on any nitrate medications, as taking Viagra along with nitrate medications can cause an abnormally sudden decrease in blood pressure.
Before taking Viagra, let your doctor know of any medical conditions such as heart disease, history of a heart attack, stroke or congestive heart failure, high or low blood pressure, liver or kidney disease, blood cell disorders such as sickle cell or leukemia, bleeding disorders, stomach ulcers, retinitis pigmentosa, physical deformities of the penis, or if you were told not to have sexual intercourse due to health reasons.
Common side effects from using Viagra include flushing, dizziness or headache, abnormal vision, stuffy nose, upset stomach, and muscle or back pain. More serious side effects include ear ringing or sudden hearing loss, irregular heartbeat, hand, ankle, or foot swelling, shortness of breath, seizures, lightheadedness, vision changes or vision loss, painful erection or erection lasting more than 4 hours, or heart attack symptoms such as chest pain, chest pressure, nausea, pain spreading to the jaw or shoulder, or sweating. If you experience any of the more serious symptoms please seek medical attention as soon as possible.
Should you experience any symptoms of allergic reaction from taking Viagra, such as hives, swelling of the face, lips, throat or tongue, or difficulty breathing, do not continue use of the medication. Seek medical attention immediately.
