Viagra is a medication used for the treatment of erectile dysfunction. Its main component is sildenafil, which is also the main ingredient in several other erectile dysfunction medications. Viagra works by relaxing the penis muscles and increasing blood flow to the penis.
While it is normally recommended that Viagra be taken at least an hour before having sexual intercourse, depending on the dosage amount being taken, it can be taken anywhere from 30 minutes to 4 hours before having sexual intercourse.
Before taking Viagra, speak with your doctor if you are taking certain medications in order to be sure you are able to take Viagra alongside these medications, especially if you are taking riociguat. Viagra should not be taken if you are taking any medications containing nitrates, as taking these two types of medications together can cause a sudden drop in blood pressure. Viagra also should not be taken if taking other medications that are used to treat erectile dysfunctions, such as avanafil, tadalafil, or vardenafil.
If you are currently taking any medications such as antibiotics, antifungal medications, HIV/AIDS treatment medications, high blood pressure medications, or prostate disorder medications, speak with your doctor before taking Viagra as it can have an affect on how these medications work.
If you have certain medical conditions such as heart disease, heart rhythm problems, history of a stroke, heart attack, or congestive heart failure, high blood pressure, low blood pressure, liver disease, kidney disease, any type of blood cell disorder such as sickle cell anemia or leukemia, a bleeding disorder, stomach ulcer, penis deformity, or retinitis pigmentosa, speak with your healthcare provider before taking Viagra.
Viagra side effects
Side effects that are common when taking Viagra are flushing, headache, blurred vision, changes in color vision, dizziness, muscle pain, back pain, stuffy nose, and upset stomach. More serious side effects that could possibly occur include symptoms of allergic reaction, such as throat, face, tongue, and lip swelling, hives, and difficulty breathing, and symptoms of a heart attack such as chest pain, nausea, sweating, and pain that spreads to the jaw or shoulder. Other serious side effects include vision changes, sudden vision loss, painful erection, erection lasting for more than four hours, ear ringing, sudden hearing loss, irregular heartbeat, seizure, lightheadedness, shortness of breath, and hand, ankle, or foot swelling. Should you experience any of the more serious side effects after taking Viagra, seek medical attention immediately and stop taking the medication.
There is no chance of missing any doses when taking Viagra, as it is meant to be taken only as needed. Should you feel as though you have overdosed on Viagra, seek medical attention as soon as possible.
