  • are pregnant, trying to become pregnant or breastfeeding
  • have a medical condition, such as liver, kidney or heart disease, diabetes or cancer
  • are scheduled for surgery
  • are under 18

Never disregard professional medical advice or delay seeking it because of something you read on this Site. If you think you may have a medical emergency, call 911 or your local emergency number immediately.
