Storing medications correctly: where they belong — and where they don't
Most Germans store their medications in the bathroom. Convenient — but wrong. The bathroom is the worst place: high humidity, temperature fluctuations, too warm. The result: active ingredients break down faster, tablets become brittle, and in the worst case you take a medication that no longer works.
The 3 basic rules
🌡
Cool (15–25 °C)
Room temperature, not the fridge. Bedroom or hallway — not next to the radiator or on the windowsill.
💧
Dry (< 60 % humidity)
Moisture destroys tablets and encourages germs. No bathroom, no kitchen. The original packaging protects.
🌑
Dark
UV breaks down active ingredients. The folding carton protects — do not decant tablets into open dishes.
Where medications do not belong
Bathroom — too warm, too damp, too many temperature fluctuations. The classic bathroom cabinet is the worst place.
Kitchen — cooking steam and heat sources (stove, dishwasher, kettle).
Car — over 60 °C inside in summer. Insulin is destroyed, suppositories melt, creams break down. In winter too: freezing makes medications ineffective.
A handbag in the sun — 30 °C outside temperature = 50 °C inside the bag. Insulin pens, eye drops and creams cannot withstand that.
Which medications belong in the fridge?
Only if the packaging says so — "Store in a cool place" or "Store in the refrigerator (2–8 °C)". The most common medications that need refrigeration:
Medications that need refrigeration — the rules
Insulin: unopened in the fridge (2–8 °C). Opened pens up to 28 days at room temperature. Never freeze — frozen insulin is ineffective.
Eye drops after opening: many must be kept cool after opening and are then only usable for 4 weeks. Warm briefly in your hand before applying.
Antibiotic suspensions after mixing: the powder keeps at room temperature. After mixing: into the fridge, only usable for 7–14 days. Exception: clarithromycin and azithromycin suspensions do not go in the fridge.
GLP-1 agonists (Ozempic, Wegovy, Mounjaro): unopened in the fridge. Opened pens 14–56 days at room temperature, depending on the product.
Vaccines: always 2–8 °C. Never freeze. Collect from the pharmacy shortly before the appointment.
Where to store in the fridge?
Not in the door (temperature fluctuations when opening). Not against the back wall (risk of freezing). Best in the crisper drawer — the temperature there is most stable.
Shelf life: what "use by" and "after opening" mean
"Use by" applies to the unopened, correctly stored medication. After this date: do not use any more. Active ingredients may have broken down, and harmful breakdown products may have formed.
"Use within ... after opening" (symbol: an open jar + a number) applies to the opened medication:
Type of medication
Shelf life after opening
Eye drops
4 weeks
Creams and ointments
3–6 months
Liquids and drops
4–12 weeks
Antibiotic suspension (mixed)
7–14 days (in the fridge)
Opened insulin pen
Up to 28 days (at room temperature)
Tip: write the opening date on the packaging
Otherwise, after 3 months you will no longer know when you opened the tube.
Warning signs of spoiled medications
Tablets discoloured yellowish or brittle
Flaking or precipitation in liquids
Changed smell
Suppositories melted and re-solidified
Cream separating into a water and a fat phase
Brownish discolouration in creams or ointments
When in doubt: do not take it — ask the pharmacy.
Special tips for heat and travel
Brief exceedances of the temperature limit (e.g. 30 °C for a few hours) are usually not a problem. With sustained heat or a holiday in the south:
Use an insulated bag or a medication cool bag
Do not place directly on cold packs — risk of freezing
In the hotel, use the coolest, darkest area of the room
Important during heat waves:
Some medications (blood-pressure-lowering drugs, diuretics) act more strongly in heat, because the body is already losing more fluid. With sustained heat, ask your doctor whether the dose needs to be adjusted.
Disposal: where to put expired medications?
Residual waste (general/black bin) — in most German municipalities the recommended route. In the original packaging, wrapped in a bag.
Pharmacy — many voluntarily take back old medications.
Never down the toilet or the drain!
Pharmaceutical residues end up in the wastewater — treatment plants cannot filter them out completely.
Check your medicine cabinet once a year
Sort out expired medications. Dispose of opened eye drops, liquids and creams with no opening date. Throw out damaged or discoloured medications.
Common questions about storage
No. Only medications where the packaging says "Store in a cool place" or "2–8 °C". Other medications can even be harmed in the fridge — solutions can flake out, gels can clump.
As a rule, no. The expiry date guarantees efficacy and safety with correct storage. After it passes, active ingredients may have broken down or harmful breakdown products may have formed. The risk is not worth it.
Unopened: fridge (2–8 °C), do not freeze. Opened: at room temperature (max. 25–30 °C), up to 28 days. Do not leave it in the car. When travelling: a cool bag with cold packs, but do not place it directly on the pack.
The packaging protects against light and moisture. You also always have the package leaflet, expiry date and batch number with you. Loose tablets in pill boxes only make sense for daily use — not for long-term storage.
Dispose of them. Most eye drops keep for only 4 weeks after opening — after that, germs may have contaminated the product. Even if there is still liquid in the bottle: get rid of it.
All your medications organized — at home too
With the digital brite medication plan you keep an overview of all active ingredients, doses and expiry dates — on your smartphone, always up to date.
