Question 5

Prescription writing guidance

Answer 5

The unnecessary use of decimal points should be avoided (e.g. 3 mg, not 3.0 mg)
• Quantities of 1 gram or more should be written as 1 g etc.
• Quantities less than 1 gram should be written in milligrams (e.g. 500 mg, not 0.5 g)
• Quantities less than 1 mg should be written in micrograms (e.g. 100 micrograms, not 0.1 µg)
• When decimals are unavoidable a zero should be written in front of the decimal point where there is no
other figure (e.g. 0.5 mL, not .5 mL)
• Use of the decimal point is acceptable to express a range (e.g. 0.5 to 1 g)
