Care Advice for Chickenpox
- What You Should Know About Chickenpox:
- Chickenpox is caused by the varicella virus.
- It's now uncommon because of the chickenpox vaccine.
- Your job is to keep your child comfortable and to limit the itching.
- Here is some care advice that should help.
- Cool Baths for Itching:
- For itching, give cool or lukewarm baths for 10 minutes as often as needed.
- Caution: avoid any chill.
- Can add baking soda 2 ounces (60 mL) per tub.
- Baths don't spread the chickenpox.
- Do not use soaps. Reason: soaps cause dry skin and make the itch worse.
- Calamine Lotion for Itching:
- Put calamine lotion on the chickenpox that itch the most.
- You can also use an ice cube on the itchy spots for 10 minutes.
- Don't use any lotion containing Benadryl in it. Reason: it can be absorbed across the skin. This can cause side effects in kids.
- Allergy Medicine for Itching:
- If itching becomes severe or interferes with sleep, give Benadryl by mouth.
- Try Not to Scratch:
- Try not to let your child pick and scratch at the sores. This can lead to infected sores.
- Trim fingernails.
- Wash hands often with soap.
- Fever Medicine:
- Give acetaminophen (such as Tylenol) for fever above 102° F (39° C).
- Never use aspirin. Reason: risk of Reye syndrome.
- Also, don't use ibuprofen products (such as Advil). Reason: may increase risk of bad strep skin infections.
- Fluids and Soft Diet:
- The mouth and throat ulcers are painful. Try to get your child to drink adequate fluids.
- Goal: keep your child well hydrated.
- Cold drinks, milk shakes, popsicles, slushes, and sherbet are good choices.
- Solids. Offer a soft diet. Also, avoid foods that need much chewing. Avoid citrus, salty, or spicy foods. Note: fluid intake is more important than eating any solids.
- For babies, you may need to stop the bottle. Give fluids by cup, spoon or syringe instead. Reason: the nipple can increase the pain.
- Liquid Antacid for Mouth Pain (Age 1 Year and Older):
- For mouth pain, use a liquid antacid (such as Mylanta or the store brand). Give 4 times per day as needed. After meals often is a good time.
- Age 1 to 6 years. Put a few drops in the mouth. Can also put it on with a cotton swab.
- Age over 6 years. Use 1 teaspoon (5 mL) as a mouth wash. Keep it on the ulcers as long as possible. Then can spit it out or swallow it.
- Caution: do not use regular mouth washes, because they sting.
- Ointment For Pain With Passing Urine:
- For girls with painful genital ulcers, use petroleum jelly (such as Vaseline).
- Put on the sores as needed.
- For males with painful pox on the tip of the penis, this also works.
- Return to School:
- Your child can go back to school after all the sores have crusted over.
- Most often, this is day 6 or 7 of the rash.
- What to Expect:
- Expect new chickenpox every day for 4 or 5 days.
- Most children get 400 to 500 chickenpox.
- They get less pox if they've had the vaccine.
- Prevent the Spread of Chickenpox in the Office:
- If your child needs to be seen, call first to the office.
- Try to bring another adult. Have one adult enter the office first for instructions.
- For nonurgent problems, the doctor may do an exam in the car.
- Call Your Doctor If:
- Chickenpox look infected (draining pus, scabs become larger)
- Gets any new chickenpox after day 6
- You think your child needs to be seen
- Your child becomes worse
And remember, contact your doctor if your child develops any of the 'Call Your Doctor' symptoms.
