Managing medicines at home
Managing Medicines, — Refills and Pharmacy Runs
Cancer treatment often means several medicines at home at once, each with its own timing, storage rules and refill process. Getting the system right from the start protects the person you are caring for and takes the pressure off you.

- Write it down first — A single written list of every medicine, dose and time is the most effective safety step you can take.
- Refills need more lead time — Some cancer medicines take days to arrive or need a new prescription each time. Never wait until the last tablet.
- Storage matters more than with most drugs — Some medicines are damaged by heat, light or humidity. The label tells you exactly where to keep them.
- When in doubt, call first — A missed dose, a wrong dose, or a medicine that looks different — all are reasons to call your team before acting.

Managing cancer medicines at home means keeping track of several drugs, each with its own timing, storage and refill schedule. The risk is not complexity — it is assuming a problem can wait. Write a complete medicine list before the first dose arrives, and never let a supply run down to the last few tablets.
Why is managing cancer medicines harder than a usual prescription?
Cancer treatment usually means several medicines running at once — some taken every day, some on specific days only, and some timed around food or other drugs.
The consequences of a missed dose or an incorrect storage condition can be more significant than with most everyday medicines. That weight falls on whoever is managing the medicine at home.
Most problems are easy to correct when they are reported the same day. The ones that become serious are the ones where someone waited, guessed, or assumed it would sort itself out.
What do I need to set up before the first dose comes home?
- Write a complete list: every medicine name, the dose, and the exact time it is taken each day.
- Check the storage instructions for each medicine — some need a cool dark shelf, some need a fridge.
- Keep all medicines in their original packaging so expiry dates and instructions stay visible.
- Ask your care team whether any medicine must not be crushed or split.
- Note which medicines must be taken with food, and which on an empty stomach.
- Find out which medicines interact with common supplements, antacids or herbal remedies.
- Save your care team's contact number somewhere that does not require a phone — on paper on the fridge.
- Ask the pharmacist how many days before running out you should call for a refill, and write that date on each packet.
- Tell every other doctor your family member sees exactly which cancer medicines they are taking.

When should you call your care team about a medicine problem?
| Situation | You can manage at home | Call your care team today |
|---|---|---|
| Missed a dose | You caught it in time and the leaflet has clear instructions — follow those | You are unsure whether to take it late, skip it, or double up — always call rather than guess |
| Wrong dose taken | — | Always call the same day, even if there are no symptoms yet |
| Medicine looks different (colour, size, packaging) | Different brand of the same medicine — confirm with the pharmacist | Call before giving it if you are not certain it is the correct medicine |
| Storage went wrong | A brief period outside conditions during a pharmacy trip — ask the pharmacist | Left in heat, sunlight or humidity for longer than a short journey — call before using it |
| Running low on supply | Well within the refill window your team gave you | You will run out before a refill can arrive — call now, not on the last day |
How do I build a routine that does not miss a dose?
Make one master medicine list
Write every medicine on a single sheet: the name, the dose, the time and any food instructions. Give a copy to one other family member and keep the original in a fixed place at home.
Use a physical system as your daily check
A seven-day pill organiser or a simple tick-sheet on the fridge removes the need to remember. Tick each dose as it is given. An empty box or unticked row tells you immediately.
Mark the refill date on each packet
When you collect a medicine, write the date by which you should reorder on the outside of the packet. That date comes from your pharmacist, based on lead time — not from when the supply runs out.
Do a weekly supply check
On the same day each week, count what you have and confirm the next week is covered for every medicine. Flag anything that needs a refill call before the week starts, not after.
Keep a one-page summary for emergencies
If your family member needs emergency care, the treating doctor needs to know every medicine they are on. A laminated one-page list kept in a wallet or on the fridge can be handed over immediately.
Did you know?
Confusion between similar-looking tablets, missed doses due to complex schedules, and incorrect storage are among the most commonly reported preventable medicine problems in outpatient cancer care.
A written medicine list reviewed at every appointment is the single step ASCO and NCCN supportive care guidance identifies as most likely to catch these errors before they cause harm.

Common questions
Frequently asked questions
What do I do if the person I am caring for refuses to take their medicine?
Tell your care team the same day — do not skip the dose and say nothing. Refusal can be caused by nausea, side effects, fear, or a feeling that the medicine is not helping, and each of those has a solution the team can offer. Adjusting the timing, changing the form of the medicine, or addressing an underlying side effect can all make a difference. Your team needs to know so they can help, and they will not be surprised — it is a common and manageable situation.
Can cancer medicines be crushed or dissolved for someone who cannot swallow tablets?
Some can, and some cannot — this varies by medicine and is not something to guess at. Some tablets have coatings that control how and where the medicine is absorbed in the body, and crushing them changes that. Capsule contents that contact skin or mucous membranes can also be harmful. Ask your pharmacist or care team specifically about each medicine on the list before changing how it is given. Do not use a pill crusher on cancer medicines without asking first.
What happens if a medicine is stored in the wrong conditions?
It depends on the medicine and how long it was outside the correct conditions. A brief trip from the pharmacy in warm weather is usually not a problem. Extended exposure to heat, direct sunlight or humidity can reduce how well some medicines work, and in some cases may affect their safety. If you are unsure whether a medicine has been compromised, call your pharmacist before giving it. Do not give a medicine you are not confident is still in good condition.
How do I manage refills when some medicines need a new prescription each time?
Some cancer medicines — particularly oral chemotherapy — require a new prescription for each supply. Your care team's prescription needs to reach the pharmacy before your current supply runs out. The safe approach is to treat the refill as a task to start well before the final few days of supply, not on the day you run out. Ask your team and pharmacist together what the lead time is for each medicine, and write that into your weekly routine from the start.
Is it safe to give a missed dose when I realise later in the day?
It depends on the medicine, and the leaflet will sometimes tell you. If the next scheduled dose is not due for many hours, taking the missed one late may be appropriate. If the next dose is soon, skipping the missed one and continuing from the next scheduled time is often safer. But these rules vary, and with cancer medicines the consequences of getting it wrong are higher than with most everyday drugs. When in doubt, call your care team rather than guessing — most have a same-day line for exactly this question.
