Viagra (Sildenafil) is an oral prescription drug used to treat males diagnosed with erectile dysfunction (ED). The active ingredient, sildenafil, works by relaxing muscle blood vessels thereby increasing blood flow to the penis. In combination with sexual stimulation, Viagra allows for a male to achieve and keep an erection. Viagra (Sildenafil) is a shorter-acting ED drug that can be effective for up to 4 hours at a time. 

Always follow your doctor's instructions while taking Viagra (Sildenafil).

  • Taken by mouth, usually as needed
  • At least 30 minutes but no more than 4 hours before sexual activity
  • With or without food but heavy and fatty foods may change the effects of the drug
  • Do not take more than 1 pill a day
  • Never change the dosage you take without first consulting your physician
