After the Shots

What to do if your child has discomfort?

Your child may need extra love and care after getting immunized. Many of the shots that protect children from serious diseases can also cause discomfort for a while. Here are answers to questions that many parents have about fussiness, fever, and pain their children may experience after they have been immunized. If you don’t find the answers to your
questions, call our office at 617-745-0050.

My child has been fussy since being immunized. What should I do?

After immunization, children may be fussy due to pain and/or fever. You may want to give your child some Tylenol or Motrin. DO NOT GIVE ASPIRIN. If you have questions on dosing please refer to the dosing chart on the side of the medication box (according to weight) or see the chart on the other side of this handout, or call the office. If the fussiness lasts more than 24 hours you should call MVPediatrics.

My child’s arm (or leg) is swollen, hot, and red. What should I do?

A clean, cool washcloth may be applied over the sore area as needed for comfort. If there is increasing redness or tenderness after 24 hours, call the office.

I think my child has a fever. What should I do?

Check your child’s temperature to find out if there is a fever. The most accurate way to do this is by taking a rectal temperature (be sure to use a lubricant, such as petroleum jelly when doing so). A fever is anything over 100.4 degrees for infants 3 months or younger and 101 degrees for older infants and children. Try treating the fever with Tylenol or Motrin. If the fever does not go down or was initially over 105 degrees or the child is under 3 months old and the temperature is over 100 degrees, call the office. If you take the temperature by mouth (for an older child) or under the arm, these temperatures are generally lower and may be less accurate. Call the office if you are concerned about temperatures.

Here are some actions you can take to reduce a fever:
  • Give your child plenty to drink
  • Clothe your child lightly. Do not cover or wrap your child
  • Give your child Tylenol or Motrin. DO NOT USE ASPIRIN
  • Sponge your child in a few inches of lukewarm (not cold) bath water.
My child seems really sick. Should I call the doctor?

If you are at all worried about how your child looks or feels, please call us.

Acetaminophen (Tylenol®) and Ibuprofen (Advil®, Motrin®) Dosing

Determine dosage by finding your child’s weight (in pounds) in the table.

  • Measuring the dosage (should be in metric units): Dosing syringes are more accurate than household utensils. Use the syringe or device that comes with the medication. If not available with the medication, medicine syringes are available at pharmacies. Household spoons are not reliable.
ACETAMINOPHEN (TYLENOL) GIVE EVERY 4-6 HOURS AS NEEDED.

  • Age limit: Do not use acetaminophen under 12 weeks of age unless directed by your pediatrician because fever during the first 12 weeks of life should be documented in a medical setting. If a fever is present, your baby needs a complete evaluation. (Exception: Fever from an immunization in a child 8 weeks of age or older. If present, please consults with your pediatrician).
  • Combination products: Avoid multi-ingredient products in children under 6 years of age.
