The Label Is More Than a Name
A prescription label packs a lot of important information into a small space. Reading it correctly is one of the simplest ways to avoid medication errors, which send many Canadians to the hospital each year.
Common Abbreviations Decoded
You may see Latin-derived shorthand on your label or your doctor's notes:
| Abbreviation | Meaning |
|---|---|
| OD / daily | Once a day |
| BID | Twice a day |
| TID | Three times a day |
| QID | Four times a day |
| PRN | As needed |
| AC | Before meals |
| PC | After meals |
| HS | At bedtime |
If anything on your label is unclear, your pharmacist will explain it — that's part of their job, and it's free.
What to Check Every Time
- Your name — make sure the bottle is actually yours.
- The drug name and strength — confirm it matches what you expect.
- The dose and frequency — how much and how often.
- Special instructions — "take with food," "avoid alcohol," "do not crush."
- The expiry date and refill information.
Avoiding Common Mistakes
- Don't double up if you miss a dose unless your pharmacist says it's safe.
- Finish antibiotics as prescribed, even if you feel better.
- Watch for interactions. Tell your pharmacist about all medications, supplements, and natural health products you take.
- Store correctly. Some medications need refrigeration; most should be kept away from heat and humidity (not the bathroom).
Use Your Pharmacist
Pharmacists are among the most accessible health professionals in Canada — no appointment needed. They can review all your medications for interactions, suggest alternatives, and in many provinces even renew certain prescriptions or prescribe for minor ailments.
Disposing of Old Medications
Don't flush expired medications or throw them in the trash. Return them to any pharmacy, which will dispose of them safely and free of charge.
