Your medication Sildenafil
Sildenafil is also known as the brand name: Viagra.
Sildenafil comes in 20, 25, 50 and 100 mg tablets.
It is most commonly used to treat erectile dysfunction but can also be used to treat high blood pressure in the lungs and heart, Raynaud phenomenon, sexual dysfunction, and esophageal motility problems. For high blood pressure in the lungs, it is taken 2.5 mg or 10 mg 3 times daily. For erectile dysfunction, sildenafil is taken once daily 1 hour prior to sexual activity. If you are using for an off label use, consult your doctor on how much you should be taking.
Some common side effects of sildenafil are flushing, headache, indigestion, eye disturbances, and nose bleeds.
Some less common side effects are insomnia, dizziness, fever, back pain, UTI, diarrhea, nausea, skin rash or skin reddening, and tingling in the skin.
While taking sildenafil, it is important to remember to tell your doctor or pharmacist if you experience any of the following:
• Signs of an allergic reaction (rash, itching, swelling, or chest tightness)
• Trouble speaking or thinking, change in balance, or change in eyesight
• You start taking new medications, vitamins, or supplements
• Your condition does not improve or you develop new or worsening symptoms
• An erection lasting longer than 4 hours
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
