Medicine Storage Temperature and Location Guide UK: Avoid Heat, Damp and Sunlight (2026)

Medicine storage temperature and location affect safety, effectiveness and shelf life. Medicines must be stored in stable conditions, away from heat, damp, sunlight and unsuitable rooms to prevent damage or reduced effectiveness.

This UK guide explains how to store medicines correctly by choosing the right location and maintaining the right temperature. It covers common mistakes, environmental risks and best practice for workplaces, care homes, schools and clinical settings.

It supports the Medicine Storage Cabinets UK guide and the Medicine Storage Risk Assessment Checklist UK.

Quick answer: medicine storage temperature and location

Medicines should be stored in a cool, dry place away from direct sunlight, heat sources and damp environments. Storage areas should be stable, clean and suitable for the type of medicine being stored.

• Keep medicines at a consistent temperature.
• Avoid heat, damp and sunlight.
• Use appropriate storage areas and cabinets.
• Follow specific storage instructions where provided.

Why temperature and location matter

Environmental conditions can affect how medicines perform. Incorrect storage may reduce effectiveness or make medicines unsafe to use.

• Heat can damage or degrade medicines.
• Cold conditions can affect certain formulations.
• Damp environments can damage packaging.
• Sunlight can alter chemical stability.
• Unstable conditions increase risk over time.

Ideal storage conditions

Most medicines should be stored in a controlled, stable environment.

• Cool temperature (typically room temperature unless specified).
• Dry conditions with low humidity.
• No direct sunlight exposure.
• Stable environment with minimal fluctuation.
• Clean and well-organised storage area.

Always check manufacturer instructions for specific temperature requirements.

Where medicines should be stored

The storage location should protect medicines from environmental risks while keeping them accessible to authorised users.

• Dedicated medical cabinets in controlled rooms.
• First aid rooms or clinical areas.
• Offices or staff areas with stable conditions.
• Lockable cabinets for secure storage.

Where medicines should NOT be stored

Certain locations create higher risk and should be avoided.

• Near radiators or heaters.
• In direct sunlight or near windows.
• In bathrooms or damp areas.
• In vehicles for extended periods.
• In areas with fluctuating temperatures.
• Near kitchens or hot equipment.

Heat risks and how to avoid them

Heat is one of the most common causes of medicine damage.

• Keep cabinets away from heat sources.
• Avoid placing cabinets against external walls with direct sun exposure.
• Ensure rooms are well ventilated.
• Monitor room temperature where needed.

Damp and humidity risks

Damp environments can damage packaging and affect medicine stability.

• Avoid storing medicines in bathrooms or near water sources.
• Keep cabinets in dry, well-ventilated rooms.
• Check for signs of moisture or condensation.
• Use suitable storage areas with low humidity.

Sunlight and UV exposure

Direct sunlight can degrade certain medicines.

• Keep cabinets away from windows.
• Use shaded or enclosed storage areas.
• Avoid transparent containers exposed to light.

Refrigerated medicines

Some medicines require refrigeration. These should be stored in a dedicated medicine fridge with controlled access.

• Use a dedicated fridge for medicines only.
• Monitor temperature regularly.
• Avoid overloading the fridge.
• Separate medicines from food or unrelated items.

Placement within cabinets

Even within a cabinet, placement matters.

• Avoid placing items near heat sources inside the room.
• Keep frequently used items accessible.
• Do not overcrowd shelves.
• Allow airflow around stored items.

Checks and monitoring

• Check storage conditions regularly.
• Monitor temperature where required.
• Inspect for signs of damage or moisture.
• Review storage locations during audits.

Common mistakes to avoid

• Storing medicines near heat sources.
• Using damp or unsuitable rooms.
• Leaving medicines in direct sunlight.
• Ignoring temperature requirements.
• Overcrowding storage areas.
