SIDE EFFECTS: Mild fever, irritability, vomiting, loss of appetite, sleepiness, diarrhea, or pain/swelling/redness at the injection site may occur. Acetaminophen may be used to reduce these effects. If any of these effects persist or worsen, tell the health care professional promptly. Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care professional right away if your child has any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms. Remember that the health care professional has prescribed this medication because he or she has judged that the benefit to your child is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell the health care professional right away if any of these rare but very serious side effects occur: high fever (105 degrees F/40 degrees C or higher), persistent crying (beginning within 48 hours of the injection and lasting longer than 3 hours), seizure, listlessness/unresponsiveness, muscle weakness/floppy muscles. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, severe dizziness, trouble breathing, itching/swelling (especially of the face/tongue/throat). This is not a complete list of possible side effects. If you notice other effects not listed above, contact the health care professional.
