Viagra Oral

Viagra® (sildenafil citrate) is a prescription drug used to treat erectile dysfunction. In clinical studies, up to 88 percent of men reported an improvement in their erections when taking Viagra. The medication works by blocking a chemical that reverses an erection by allowing blood to flow out of the penis. In most cases, it starts working within 30 minutes.
 
Viagra is an oral medication that is taken as needed, usually one hour before sexual activity. However, you should not take more than one tablet in a day. Potential side effects include:
 
  • Headache
  • Facial flushing
  • Indigestion (dyspepsia)
  • Nasal congestion
  • Dizziness.
