Labelling requirements (7)
- Quantity + API & Strength + Dosage form
- Batch / reference number
- Dosing + administration instruction
- Patient name
- Date of dispense, expiry date
- Pharmacy address
- Cautionary label
Prescription requirements (5)
- Patient’s name & IC
- Dosing instructions
- Medication name & dose

Eyedrops dose calculations (2)
Eyedrop 1% = 10 mg/1ml = 20 drops
1 drop = 0.05 ml (0.5 mg / administration)
(Number of drops = volume in microliters / 30 microliters)
Creams dose calculations (2)
2 Finger Tip Unit = 1 g
1 hand = 0.5 FTU
Insulin dose calculation principles
- Must prime the pen before each injection use (2 units each time)
- Calculate total amount (unit) needed per day x number of days
- Each pen = 300 units
—> calculate number of pens needed (round up)
Calculation on % strength (w/v, v/v, w/w)
W/w = g/100 g
W/v = g/100 mL
V/v = mL/100 mL
w/w x specific gravity = w/v
Equations for calculations
(combining drug, dilution, specific gravity)
- Combining drug: strength = total amount / total mass or volume
- Dilution: Q1C1 = Q2V2
- Specific gravity = density of substance / density of water (1g/cm3)
