- Active ingredient
- The working part of a medicine, the thing that produces the effect. Listed on the back panel of anything sold off the shelf. Two products with different names on the front can carry the same active ingredient inside.
- Adherence
- The word professionals use for taking a medicine the way it was prescribed. If someone asks about your adherence, they're asking, without judgment, how it's actually going.
- Brand name and generic name
- Every medicine has a chemical name and often a manufacturer's trade name. A generic version contains the same active ingredient and generally costs less. Confusion between the two names is one of the commonest causes of accidental doubling up.
- Brown bag review
- An appointment where you bring every container in a bag rather than just a list, so labels can be checked directly.
- Combination product
- A single product containing more than one active ingredient, usually sold for multiple symptoms at once. The reason to read the panel before you buy.
- Deprescribing
- The planned, supervised reduction or stopping of a medicine that's no longer worth its place. A decision made with a prescriber, never alone.
- Formulary
- The list of medicines an insurance plan covers, and at what cost. Two similar medicines can sit at very different prices on the same formulary.
- Interaction
- A change in how a medicine behaves because something else is present, whether another medicine, a supplement, a food, a drink, or another condition.
- Medication reconciliation
- The formal act of comparing two lists, usually the one you arrived with and the one you're leaving with, to make sure nothing was added, dropped, or duplicated by accident. Ask for it by name at any hospital discharge.
- Pill organizer
- A box with compartments for each day, and often for each time of day. Turns "did I take it?" into something you can see rather than remember.
- Polypharmacy
- Taking several medicines at once, usually said of five or more. It's a description, not a diagnosis, and it's a reason for regular review rather than for alarm.
- Prescribing cascade
- When a side effect of one medicine is mistaken for a new condition and treated with a second medicine. Common, rarely anyone's fault, and one of the main things a full review looks for.
- Refill synchronization
- A pharmacy service that lines your prescriptions up so they're all ready on the same day each month. Turns several trips into one.
- Side effect
- Anything a medicine does that isn't the effect you wanted. Ranges from trivial to serious. Always worth reporting, never worth acting on alone.
- Take-back program
- A place that safely collects unused or expired medicines, often a kiosk at a pharmacy or a police station. Ask your pharmacist what's near you.
- Titration and tapering
- Gradually increasing or decreasing an amount over time, on a plan, rather than starting or stopping all at once. Some medicines genuinely require this, which is one of the reasons stopping on your own is unsafe.
