When to Use: Treatment of allergic reactions, nasal allergies, hives and itching.

Table Notes: 

  • Age limits – For allergies, don’t use under 1 year of age. (Reason: it causes most babies to be sleepy). For colds, not advised at any age. (Reason: no proven benefits). They should be not be given if under 4 years old. If under 6 years, don’t give products with more than one ingredient in them. (Reason: FDA recommendations 10/2008).
  • Dose – Find the child’s weight in the top row of the dose table. Look below the correct weight for the dose based on the product you have.
  • Measure the dose – Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medicine.  If not, you can get a med syringe at drug stores. If you use a teaspoon, it should be a measuring spoon. (Reason: regular spoons are not reliable.) Keep in mind 1 level teaspoon equals 5 mL and that ½ teaspoon equals 2.5 mL.
  • Adult dose – 50 mg
  • How often – Repeat every 6 hours as needed.
  • Children’s Benadryl fastmelts – Each fastmelt tablet equals 12.5 mg. They are dosed the same as chewable tablets.
