Benadryl dosage by weight

For children weighing 2-6 kilograms, administer 12.5 mg of Benadryl every 6 hours as needed. For children between 6 and 21 kilograms, use 25 mg per dose, also every 6 hours. Remember to always check the label for specific instructions and only use the liquid formulation for these weights.

Children weighing over 21 kilograms can take the adult dosage of 25-50 mg every 4-6 hours. However, exceeding 300 mg within 24 hours is strongly discouraged. Accurate weight measurement is paramount for safe medication.

Important Note: Always consult a doctor or pharmacist before administering Benadryl, particularly for infants, young children, or individuals with pre-existing health conditions. They can help determine the appropriate dosage based on individual needs and potential interactions with other medications.

Never exceed the recommended dosage. Adverse reactions are possible with overuse, so close monitoring is key. Keep Benadryl out of reach of children. If you notice any unusual reactions, stop administration immediately and seek medical advice.
