Cowling rule is another method for determining the dosage of a drug to prescribed to a child. For this rule, the formula d=D(a+1) ------ 24 gives the child's dosage d, Where D is the adult dosage and a is the age of the child in years. If the adult dosage of a drug is 600 milligrams and a doctor uses this formula to
