My Infant Gets a Fever After Shots

Fever Reducers

Fever reducers can tackle the fever, as well as ease muscle aches. However, before using these medications, consult your doctor. Typically, fever reducers aren’t recommended for low-grade fevers. If your doctor approves, use the drugs as directed. Also, never give your infant aspirin to ease her fever. Aspirin in children is linked to Reye’s syndrome, a serious and deadly condition.


If your infant has a fever after vaccines, encourage her to stay on a normal feeding schedule. A fever increases your baby’s risk for dehydration. Offer younger babies breast milk or formula.
