Your details

Use the most recent measured weight, not an estimate, whenever possible.
kg
How the prescriber wrote the order. Per-day amounts are split across the daily doses.
The figure from the label or prescriber that matches the dosing basis you chose above.
mg/kg/dose
Doses per day. Used to split a per-day amount and to total a per-dose amount.
The ceiling for one dose. Leave at 0 if there is no cap. A single dose is never larger than this.
mg
The 24-hour ceiling for this drug in mg, from the label. Many drugs state it per kilogram, for example acetaminophen 75 mg/kg/day and ibuprofen 40 mg/kg/day, so multiply by the weight first. Leave at 0 to skip the check. This is a different limit from the per-dose cap above.
mg
Turn on to convert the mg dose into millilitres of a liquid medicine.
The mg of drug stated on the bottle, e.g. the 160 in "160 mg per 5 mL".
mg
The mL the strength is stated per, e.g. the 5 in "160 mg per 5 mL". Use 1 for a tablet of that mg.

Optional: price a full course from the bottle size and price.

About 300 mg (9.38 mL) per dose.

  • Give about 300 mg per dose, 4 times a day, for a daily total near 1,200 mg.
  • At the strength entered, that is about 9.38 mL per dose, measure it with a marked oral syringe, not a kitchen spoon.
  • No maximum daily dose was entered. The per-dose cap is not the same as the daily limit, so look up the 24-hour maximum for this drug and enter it to have it checked.
  • That daily total works out at 60 mg/kg/day, which is the unit most labels use to state the 24-hour maximum.

Next stepVerify the drug, dose, volume and frequency with the prescribing clinician or pharmacist before giving any medicine.
