Brackets can be replaced with commas for a more formal writing style.
Here is how the example in the image above can use commas instead of brackets:
Mr Ferguson is prescribed metformin, a 2mg tablet taken in the morning, and lactulose, 50mg of syrup, taken after lunch.
Some students would put the doses of the 2 medications in brackets but, in general, brackets should be avoided in formal writing.
Commas work well here to separate the dose from the name of the medication. Here’s another example:
Please monitor Mrs Walker’s compliance with her medication. She is prescribed warfarin, 1 tablet to be taken in the morning, and Ventolin, to be taken as required.
Commas have many uses:
- to introduce the patient’s family members in your letter.
