Latin abbreviations in medicine

Until comparatively recently, Latin was considered the language of science, and so there are countless medical terms that have Latin roots (and many others that have Greek roots, and still some that have Arabic roots). I'll add more posts on this topic eventually, but I thought I'd start with some abbreviations that are commonly used when writing a prescription.

• o.d. stands for omni die (once every day)
• b.d. (or b.i.d.) stands for bis in die (twice a day)
• t.d.s. stands for ter die sumendum (three times a day); alternatively t.i.d., standing for ter in die can be used
• q.d.s. stands for quater die sumendum (four times a day); alternatively, q.i.d., standing for quater in die can be used.
• stat is the shortened version of statim, meaning immediately

Also, nocte and mane are the Latin words for 'morning' and 'evening', respectively.

Just so you'd know.
