Foundayo storage: no fridge, no fuss

Last reviewed: 23 August 2026

Why this matters more than it sounds

Anyone who has used Mounjaro or the Wegovy injection knows the cold-chain anxiety: the fridge temperature, the delivery window, the ice pack that arrived warm, the question of whether a pen left out overnight is still usable. Tablets remove that entire category of worry. It is a small thing on paper and a large thing in daily life, and for frequent travellers it can be the deciding factor between medicines, as covered in our Foundayo vs Mounjaro comparison.

The original packaging rule

Keep tablets in the bottle and carton they came in. That packaging is not just branding: it shields the tablets from light and moisture, and it carries the batch number, expiry date and dispensing label, all of which matter if there is ever a supply query, a recall, or a border question while travelling.

Decanting a week's tablets into a pill organiser for daily convenience is a practical compromise many people make, and if you do, keep the organiser somewhere cool and dry, keep the original packaging for the rest of the supply, and never mix Foundayo loose with other medicines where a mix-up becomes possible.

Places that quietly ruin medicines

• The bathroom cabinet. The classic mistake. Repeated heat and humidity from showers is one of the worst environments for tablets, despite being where most households keep medicines.
• A parked car. Interiors can exceed 50C within an hour of sunshine. Never leave a supply in the glovebox.
• Sunny windowsills and shelves above radiators. Direct heat and light both degrade medicines over time.
• Near the kettle, hob or dishwasher, where steam is constant.
• The fridge. Not dangerous, but unnecessary, and condensation on a cold bottle brought into a warm room introduces exactly the moisture the carton is protecting against.

A bedroom drawer, a kitchen cupboard away from the kettle, or a shelf in a cool hallway all work perfectly.

Deliveries and hot weather

Because there is no cold chain, a Foundayo parcel that waits a few hours in a porch is generally not a crisis in the way an insulin-style delivery would be. Even so, use common sense in a heatwave: arrange delivery for a day you are in, use a safe place out of direct sun rather than a hot doorstep, and bring the parcel indoors promptly. If a delivery arrives visibly damaged, obviously heat-affected, or with a broken seal, do not take it. Contact the pharmacy for a replacement, and if the provider is unhelpful, that is worth reporting to us as a verification concern.

Travel and holidays

Room-temperature storage still applies abroad, which in practice means a shaded spot in your accommodation rather than a beach bag or a hire car dashboard. Hand luggage, original packaging and a copy of your prescription cover the rest. The full picture, including the travel insurance declaration that catches people out, is in our travel guide.

Expiry, leftovers and disposal

Check the expiry date on the carton when a new supply arrives, and again if a pack has sat unused during a treatment break. Do not take expired tablets: potency is not guaranteed once the date has passed.

Never flush medicines or put them in household waste, where they can reach water systems or children. Return unused or expired tablets to any pharmacy, which will dispose of them properly and free of charge, no questions asked. If you have stopped treatment altogether, our stopping guide covers what else to plan for.

Storing safely around other people

Foundayo is prescribed for you after an individual assessment, and it should never be shared, however well-intentioned. Keep it out of sight and reach of children, and be aware that a bottle of tablets on a kitchen worktop is more accessible to a curious child than an injection pen in a fridge. If a child swallows any, contact NHS 111 or your GP immediately, or call 999 if they are unwell.
