Acetaminophen (Tylenol) Dosing for Babies

Acetaminophen is commonly used to relieve mild to moderate pain and reduce fever. It’s safe for younger infants under close guidance but is strictly weight-based. Avoid frequent dosing (more than 5 doses in 24 hours) to prevent potential liver issues.

Note: Use an appropriate dosing tool like an oral syringe. Avoid using kitchen spoons, as they can lead to inaccurate dosing.

Weight (lbs) Approximate Age Dose (mg) Frequency
6–11 lbs 0–3 months Consult doctor Every 4–6 hours, as needed
12–17 lbs 4–11 months 80 mg Every 4–6 hours, as needed
18–23 lbs 12–23 months 120 mg Every 4–6 hours, as needed

Ibuprofen (Advil/Motrin) Dosing for Babies

Ibuprofen is effective for fever and pain relief but isn’t recommended for infants under six months due to possible side effects. Unlike acetaminophen, ibuprofen’s effects last longer, which means dosing every 6–8 hours.

 

Note: Avoid ibuprofen in babies with dehydration or suspected kidney issues. Always use a syringe for exact dosing.

Weight (lbs) Approximate Age Dose (mg) Frequency
12–17 lbs 6–11 months 50 mg Every 6–8 hours, as needed
18–23 lbs 12–23 months 75 mg Every 6–8 hours, as needed

 

Diphenhydramine (Benadryl) Dosing for Babies

Diphenhydramine, commonly known as Benadryl, is an antihistamine used for allergic reactions. It’s generally not recommended for babies under six months, and even for older babies, dosing should be closely monitored due to risks of sedation or paradoxical hyperactivity.

 

Note: Diphenhydramine is often reserved for significant allergic reactions and should be used sparingly. Infants under two years old should seek direct guidance from a pediatrician.

 

 

Weight (lbs) Approximate Age Dose (mg) Frequency
