Diphenhydramine dosage for children
Diphenhydramine (e.g., Benadryl) is a drug that is used to treat certain types of allergic reactions. Below is a dosage chart for children. It is better to use a dosing device rather than a spoon. Be careful, there are several products with different diphenhydramine concentrations.
To determine the right dosage for your child, follow these steps:
- Find the line that corresponds to the child's weight (in pounds or kilograms).
- Identify the proper dose based on the product you have in hand.
- Administer the dose every 6 hours for a maximum of 4 doses within a 24-hour period.
