For medications that require multiple doses per day:

The calculator uses these formulas to provide accurate dosage recommendations based on the medication selected and the patient's weight.

Assumptions

This calculator makes the following assumptions:

• Standard adult patient weight range (40-120 kg)
• Typical dosage ranges for common mental health medications
• Standard dosing frequency (2-4 times per day)
• No special considerations for pediatric or geriatric patients

Worked Example

Let's calculate the dosage for a 70 kg patient taking 10 mg/kg/day of a typical mental health medication:

1. Total Dosage = 70 kg × 10 mg/kg/day = 700 mg/day
2. If the medication is taken twice daily: 700 mg ÷ 2 = 350 mg per dose

Using the calculator with these values would show a total daily dosage of 700 mg and 350 mg per dose.
