Storing oral chemotherapy at home

In their original packaging, in a cool, dry place away from direct sunlight, and locked away or well out of reach of children and pets. Most oral chemotherapy medicines should be kept at room temperature, but what counts as room temperature on a medicine label is often cooler than an Indian home in April, May or June. High heat and humidity can damage some tablets and capsules, making them less effective or causing them to crumble or stick together. Places that seem convenient are often the worst: kitchen shelves near the stove, bathrooms full of steam, window sills in the sun, cupboards against a hot outside wall, and the dashboard or boot of a car.

Some medicines have special storage instructions, such as keeping them in the fridge, keeping them in a desiccant-lined bottle, or protecting them from light, so always read the label and ask your pharmacist. Keeping tablets in the original container matters because it shows the medicine name, strength, expiry date and instructions, protects the tablets from moisture and light, and prevents mix-ups with other medicines. Chemotherapy should be stored separately from other family medicines, food and drinks, ideally in a closed box or bag in a dedicated place. A locked cupboard or a high shelf protects children, who may mistake tablets for sweets. If you have grandchildren visiting or a busy household, it is worth checking storage before every visit.

Power cuts and fridge medicines

If a medicine must be refrigerated and the power goes off for a long time, ask your pharmacist whether it is still safe to use.

Check expiry dates

Do not use tablets past their expiry date. Return them to the pharmacy.

Damaged tablets

If tablets look discoloured, cracked, sticky or different, do not take them. Ask your pharmacist.

It cannot tell you the exact storage temperature or conditions for your medicine. These are printed on the label and in the leaflet, and your pharmacist can explain them. Some medicines have very specific requirements.

It also cannot tell you whether a tablet exposed to heat or damp is still safe. If you are unsure, do not take it, and ask your pharmacist or team.

Blister packs

Keep tablets in blister packs until you take them, rather than pushing them all out in advance.

Pill organisers

Check with your pharmacist before using one, as exposure to air and moisture can affect some tablets.

Liquid medicines

Liquids often have short shelf lives once opened. Check the label for the discard date.

Shared homes

In joint families or hostels, a lockable box helps keep tablets safe and private.

Hospital stays

If admitted, take tablets in original packaging and tell staff, who will store them safely.

End of treatment

Return any leftover tablets to the pharmacy rather than storing them for later.

Keep a spare copy of instructions

Store the leaflet and your written instructions with the tablets.

Ask when in doubt

Pharmacists are happy to advise on storage for your specific medicine.

Why heat and humidity damage medicines

Tablets and capsules are made to stay stable within certain temperature and moisture limits. In very hot rooms, some medicines can start to break down chemically, so that less active medicine is present when you take them, even if the tablets look normal. High humidity can make tablets absorb moisture, swell, crumble or stick together, and can soften capsule shells. Direct sunlight can also affect some medicines. These changes are not always visible, which is why storage matters even when tablets appear fine. In many Indian homes, summer indoor temperatures, steam from cooking and monsoon humidity can all exceed what medicine labels intend, so choosing the coolest, driest place available is an important part of keeping treatment effective.

Keeping medicines organised in a busy household

In homes where several family members take medicines, mix-ups are easy. Keep chemotherapy in its own labelled box, separate from blood pressure, diabetes and other family medicines, and never transfer tablets into unlabelled containers. If an elderly parent and the patient both take tablets at the same times, consider different coloured boxes or separate shelves. Tell anyone who helps with medicines, including domestic helpers and visiting relatives, where chemotherapy is kept and that only the designated person should handle it.

Before a long hospital stay or trip

If you will be away from home, plan how tablets will be stored and taken. Take enough for the time away in original packaging, keep them cool, and tell hospital staff or hosts that you have chemotherapy that must be stored safely.

What to do next

Choose a cool, dry, locked or high place away from kitchens, bathrooms and sunlight, keep tablets in original packaging and separate from other medicines, follow any fridge instructions exactly, check expiry dates, and call your team if anyone swallows a tablet by mistake.
