Topic Overview

This information is for people who may help you if you are too weak or confused to treat your low blood sugar. Make a copy for your partner, co-workers, and friends.

  • Make sure the person can swallow. Give the person ½ teaspoon of water. If the person can swallow the water without choking or coughing:
    • Give him or her 125 mL (4 fl oz) of liquid (juice or soda pop) from the list of quick-sugar foods, or glucose tabs or gel if available.
    • Wait 10 to 15 minutes.
    • Offer the person more quick-sugar food if he or she is feeling better but still has some symptoms of low blood sugar.
    • Check the person's blood sugar level using his or her blood sugar (glucose) meter if available.
    • Stay with the person until his or her blood sugar level is 4.0 mmol/L or higher.
    • Offer the person a snack (such as cheese and crackers or half of a sandwich).
    • If the person becomes more sleepy or seems to have no energy, call 911 or other emergency services.
  • If the person is unconscious or unable to swallow:
    • Call 911 for emergency care right away.
    • Give the person a shot of glucagon if one is available. See a slide show about how to give a glucagon injection.
    • If emergency help has not arrived within 5 minutes and the person is still unconscious, give another glucagon shot.
    • Stay with the person until emergency help comes.
