The Pediatric dose calculator estimates the infant’s dosage based on Weight, BSA, Young Rule, and the Clark Rules.
Pediatrics is the branch of medicine concerned with the health and medical care of infants, children, and adolescents, from the date of birth to 18 years. The Word “Paediatrics” is a Greek word and meaning is a healer of children.
Let’s have a look at various pediatric terms and it is important to find the pediatric dosage.
Pediatric Dosage Calculations are not a simple task when estimating the infant dosage. Infants are sensitive and overdose can harm their nourishment. The most common method of finding the Pediatric dosage is by the Weight and the Body Surface Area (BSA) of children. The pediatric dosage calculations formula can be different when we are considering various factors like weight and BSA.
Pediatric dose calculation is a sensitive thing for infants as the overdose can be the cause of toxicity. The main reason behind their physiological process is absorption, metabolism, and excretion. The hepatic and the renal functions in infants present a slower metabolism. This is the main reason only the safe pediatric dosage calculations formula can be calculated for adults. The Infant’s pediatric dosage calculations were made by comparing the safe dosage for the adults.
Child dose by weight = (mg/day) = Adult Dose in mg/kg or mg/kg/day x Child Weight in kg
OR
Child dose by weight = (mg/dose) = Adult Dose in mg/kg/dose x Child Weight in kg
The pediatric dosage formula based on the weight of the infants may lead to overdose as some of the infants do grow faster than others. The body surface area BSA provides us with more accurate and precise values. Research has shown after 1 year organs’ growth and physiological functions conform more perfectly to the BSA than body weight. The pediatric dose calculation for various drugs like Azithromycin, Prednisone, and Keflex should be calibrated by the BSA. There are special Chemotherapeutic drugs and the Prednisolone pediatric dose calculator prepared for a specific drug. The online help can be gathered by the Keflex pediatric dosing calculator.
When the child’s height and weight are known than the Infants BSA can be calculated by the following formula:
Child dose by BSA (mg/day) = Adult Dose in mg/day x BSA in m2 / 1.73
If the concentration is known in mg/m2
Child dose by BSA (mg/day) = Adult Dose in mg/m2 x BSA in m2
Young’s rule’s for the pediatric dosage are normally based on age and approximate body weight of the child during the first year of adolescence. This is the main reason Young’s Rules is not only considered to find the dosage for pediatrics but also for adults.
How to calculate pediatric doses by Young’s rule is simple, but you need to compare the calculations by the adult dose.
Child dose by Young’s rule (mg/day) = Adult Dose (mg/day) x [Age / (Age+12)]
Clark’s rules for the Pediatric Dosage Calculations use the proportional body weight rather than the standard mean weight of 150 Lb. Therefore, for this methodology, the weight of the child is considered in Lbs, not in Kg.
How to calculate pediatric doses by Clark’s Rules is given below:
Child dose by Clark’s rule (mg/day) = Adult Dose (mg/day) x (Child Weight in Lbs /150)
We normally use the Young and Clark’s rules in prescribing the radioactive dosage of medicines.
Some dosages are available in multiple concentrations and quantities. For example, a solution of 5mg/10mL has a specific frequency and we are going to take it according to the prescribed prescription. The Azithromycin pediatric dose calculator is able to compute the quantity of solution for infants. The pediatric dosage calculations formula can be different for various medicines, but is based on the frequency of the dose.
The following table summarizes the main administration frequencies, as commonly found on prescriptions:
| Freq. | Explanation |
| qD | Stands for “quaque die” meaning once a day – this dosage is the same as the dose per day |
| BID | Stands for “bid in die” meaning twice a day, so a dose of medicine must be administered twice during the waking hours |
| TID | Stands for “ter in die” meaning three times a day, so a dose of medicine must be administered thrice during the waking hours |
| QID | Stands for “quater in die” meaning four times a day, so a dose of medicine must be administered four times during the waking hours |
| q8 hr, q6 hr
q4 hr q3 hr q2 hr q1 hr |
The q stands for “quaque” which means every, and the h indicates the number of hours, where a dose of medicine must be administered every 8, 6, 4, 3, 2 hours, respectively every hour. |
How to do pediatric dosing according to the prescribed, prescription, one needs to use the safe dose range calculator. This would help to avoid the overdose of pediatric salt and chemicals.
The Pediatric Dosing Calculator can function by the given instructions and can accurate estimation:

The Pediatric dosage calculation is specially designed concerning physical, mental, and social health. For children from the age of birth to adulthood, Pediatric care encompasses a broad spectrum of health care services and the pediatric dose calculator provides us with more accurate dosage calculations.
A Patient who is 12 years of age, but with a weight not exceeding 36 Kg is still considered to be a pediatrician. When you are using the safe dose range calculator, you can estimate the pediatric dosage of any age.
Pediatric medication may be sometimes a matter of concern when you are taking a new form of salt for your infant. The pediatric dose calculator can estimate the pediatric dosage calculations.
