Frequently asked questions
Only when the active ingredient is IDENTICAL and the route is the same (oral). Modified-release tablets (slow-release, enteric-coated) usually have no liquid equivalent — switching loses the time-release behaviour and can cause overdose or treatment failure. Always check the formulation type before swapping.
1 teaspoon (tsp) = 5 mL by international convention. The 'teaspoon equivalent' in the result is a rough kitchen-spoon check. Always use the calibrated syringe or measuring cup that comes with the medicine — kitchen spoons vary by 20-50%.
Most paediatric syringes are marked in 0.25 mL increments. Rounding to that precision gives a measurable dose. The 'rounding error' shows how many mg you over- or under-dose by — typically <5% of the target, which is clinically negligible.
Yes. If you need 500 mg and the syrup is 250 mg/5 mL, you need (500 × 5) ÷ 250 = 10 mL = 2 teaspoons. The tool handles the conversion automatically.
Don't substitute. Modified-release tablets (often marked SR, XR, ER, CR) release the drug slowly over hours. Crushing them or swapping to standard syrup destroys that mechanism and can cause an immediate-release overdose. Speak to the prescriber for an alternative immediate-release formulation if the patient can't swallow.
