Doses follow the AAP HealthyChildren dosing tables; mL is for the liquid concentration shown. If a weight falls between rows, use the lower dose. If your child's weight and age fall in different rows, use weight, but the age limits still apply: no ibuprofen under 6 months, and call the doctor before any acetaminophen under 12 weeks.
For older children and teens, tablets or chewables may be easier than large liquid volumes—confirm the exact tablet strength on the label.

If you want a plain-English primer before using any chart, read the parent guide to pediatric dosage by weight. It explains why weight, concentration, and clinician confirmation matter.
Looking for antihistamine dosing charts? Use the dedicated pages for diphenhydramine (Benadryl), cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra). These are labeled by age, not weight, and each page adds safety notes.
If you want a parent-friendly overview before choosing a chart, start with the pediatric allergies guide.

Alternating can be used in select cases but increases complexity. Follow clinician guidance and avoid accidental double-dosing.
Use clinician guidance. Some OTC products are not recommended for infants, especially ibuprofen.
Weigh the child if possible. Avoid guessing when dosing medications.
Use the provided dosing device and measure at eye level for accuracy. Avoid kitchen spoons.
Seek medical advice if fever persists, symptoms worsen, or the child looks ill.
No. Labels and clinician guidance take priority over any chart or calculator.
A Benadryl (diphenhydramine) dosing chart lists the label dose by age, not weight: do not use under 2 years, ages 2-5 only if a doctor directs, 6-11 years 12.5-25 mg. It is for allergy symptoms and does not replace clinical advice.
A Zyrtec (cetirizine) dosing chart lists the label dose by age, not weight, for allergy control. Always verify the product label and clinician guidance.
A Claritin (loratadine) dosing chart lists common once-daily age-based doses for children. Always verify the exact product form and label directions before dosing.
An Allegra (fexofenadine) dosing chart lists common age-based doses for children and highlights formulation-specific cautions like using water instead of fruit juice.
