Table Notes:
- AGE LIMITS: For allergies, don't use under 1 year of age (Reason: it's a sedative). For colds, not recommended at any age (Reason: no proven benefits) and should be avoided if under 4 years old. Avoid multi-ingredient products in children under 6 years of age (Reason: FDA recommendations 10/2008).
- DOSAGE: Determine by finding child's weight in the top row of the dosage table
- MEASURING the DOSAGE: Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medication. If you use a teaspoon, it should be a measuring spoon. Regular spoons are not reliable. Also, remember that 1 level teaspoon equals 5 ml and that ½ teaspoon equals 2.5 ml.
- FREQUENCY: Repeat every 6 hours as needed
- ADULT DOSAGE: 50 mg
- CHILDREN’S BENADRYL FASTMELTS: Each fastmelt tablet contains the equivalent of 12.5 mg of Diphenhydramine HCL and dosed the same as chewable tablets
