Dosing[]

Young's Formula Take the age in years of the child and divide by the age in years of the child + 12 and this will equal the portion of the adult dose to administer. Example: a 6 year old child divided by 6 + 12 (18) = 1/3 the adult dose

Dillings Formula Take the age in years of the child and divide by 20 to get the portion of the adult dose to administer. Example: a 6 year old child = 6 divided by 20 = 3/10ths

Cowling's Rule Divide the age at the next birthday by 24. Example: a 5-year-old would be 6 at the next birthday; 6 divided by 24 equals 6/24 or 1/4. Dose would be 1/4 the adult dosage.

Clark's Rule Divide the weight in *pounds of the child by 150 to give the approximate fraction of the adult dosage. (*pounds: using a dosage based on the weight is a more sensible choice. Children vary considerably in size despite their ages. A small 6 year old would require less than a large 6 year old)

Note: Administering home remedies to infants and young children is NOT recommended without professional guidance.

0 to 3 months = 2 drops 6 to 9 months = 4 drops 1 yr to 18 mos = 7 drops 2 to 3 years = 10 drops 4 years = 1/4 tsp or 15 drops or 1/6 adult dose 6 years = 1/4 tsp or 15 drops or 1/4 adult dose 8 years = 1/3 adult dose 9 to 12 years = 1/2 tsp or 30 drops 12 years = 1/2 adult dose 15 years = 2/3 adult dose or 3/4 tsp or 45 drops 18 or over = adult portion of 1 tsp or 60 drops
