Shingles

What it is

Shingles occurs when the chickenpox virus becomes active again in someone who has previously had chickenpox. Painful spots appear, often on only one side of the body. Symptoms may last 2 to 3 weeks.

What you can do at home

What to do
  • To relieve pain, take acetaminophen (Tylenol). When in doubt, follow the advice provided by a pharmacist. 

Caring for the spots

  • Wash the spots daily with a mild soap and rinse thoroughly. 
  • Pat the skin dry. Do not rub. 
  • Do not remove firmly attached scabs. Remove only loose scabs that catch on clothing. 
  • Cover all spots with a bandage to reduce the risk of spreading the virus to someone else. 

Itchy skin

  • Wear loose, soft clothing. 
  • For children aged 0 to 2 years: Use mittens as needed to prevent scratching. 
  • Apply cold, wet compresses to the skin for 30 to 90 minutes every 2 to 4 hours, as needed.
  • Moisturize the skin after a bath or shower, for example with a lanolin-based cream, petroleum jelly, or mineral oil, unless this makes the rash worse. 
  • Take a 10- to 30-minute lukewarm bath without soap, bubble bath, or scented products 3 to 4 times a day. 
  • If the skin is dry, take only one 10-minute bath a day. 
  • If the skin is not dry, add baking soda to the bathwater: 50 to 60 mL for children under 2 years of age, or 250 to 500 mL for adults and children aged 2 years and older. 

Important: Never leave a child unattended in the bath. 

Spots in the mouth

  • Rinse the mouth with cold water, as needed. 
  • Drink cold fluids. 
  • Avoid acidic, spicy, salty, hard, or very hot foods. 
  • Brush teeth with a very soft toothbrush. 
  • Avoid mouthwash containing alcohol. 
  • For young children: Use a cup, spoon, or syringe instead of a bottle because sucking increases mouth pain. 
  • For older children: Use a straw. 
  • From age 4: Rinse the mouth with a baking soda solution up to 4 times a day. Mix ½ teaspoon of baking soda with 1 cup (250 mL) of water that has been boiled for 1 minute and has fully cooled. Use 5 mL each time for children aged 4 to 6 years, 5 to 10 mL for children aged 6 to 12 years, and 15 mL from age 12. 
  • Apply an anesthetic gel in the mouth before eating. Ask a pharmacist for advice. 

Important: Anesthetic gel is not recommended for young children. When in doubt, ask a pharmacist for advice.

To prevent spreading the infection

  • Wash hands often. 
  • Do not share items that have been in contact with the sick person’s mouth. 
  • Stay home during the most contagious period. 
  • Avoid close contact with other people, especially babies, children, older adults, and people who are immunocompromised. 
  • Regularly clean and disinfect frequently touched surfaces and objects.
Avoid
  • Scratching the skin
  • Sun exposure, because heat makes itching worse
  • Ibuprofen (Advil) or aspirin
  • Swimming until all the blisters have turned into scabs.
