Young's rule is a method to convert adult dosage of medicine for children.
Let N= child's age,
D is the adult dosage of a medicine,
C is the corresponding children's dosage of the medicine
C+=+D%2F%28%28N%2B12%29%2FN%29
As an example, if the adult dosage is 100mg and the child is 8 years old, then
C+=+D%2F%28%28N%2B12%29%2FN%29
C+=+100%2F%28%2810%2B12%29%2F10%29
C+=+1000%2F22
C+=+45.5
The 10 year old child's dose would be approximately 45 mg.
Remember always check the label for appropriate dosage and age limits with any medicines.
