Essential Medicines to Keep at Home for Emergencies: A UK Preparedness Guide

Pharmacies are usually easy to access in the UK, but even a relatively minor disruption can make obtaining medicine difficult. Severe weather, transport problems, power cuts, bank holidays, temporary pharmacy closures or a household illness can all leave you unable to buy basic remedies when you need them.

Keeping a sensible supply of familiar over-the-counter medicines at home can therefore improve household resilience. It allows you to manage common, minor symptoms without making an unnecessary journey while somebody is unwell.

This does not mean buying large quantities or attempting to treat serious conditions yourself. A small, carefully chosen and properly maintained supply is far more useful than a cupboard full of unfamiliar products.

This guide focuses mainly on common non-prescription medicines. All medicines should be used according to the instructions on the packaging and patient information leaflet, or as directed by a pharmacist, GP or other qualified healthcare professional.

For a broader look at planning for illness and disrupted healthcare access, read our guide to medical preparedness for UK households.

Why keep medicines at home?

Emergency preparedness is not limited to major disasters. Ordinary events can temporarily make pharmacies harder to reach, including:

• Power cuts
• Snow, flooding and severe storms
• Public transport disruption
• Illness during evenings or bank holidays
• Temporary pharmacy closures
• Several family members becoming ill together
• Short periods of self-isolation
• Caring for children, older relatives or somebody with limited mobility

Having familiar medicines available can make these situations easier to manage. It may also mean that a healthy family member does not need to leave someone who is sick in order to find an open pharmacy.

The aim is to cover familiar, minor health needs for a short period. Medicines kept at home should never be treated as a substitute for professional advice, urgent treatment or emergency care.

This is especially worth considering when you prepare for a power cut or plan what your household would do during the first 24 hours after a disaster.

Choose medicines for your household

There is no single list of medicines that is suitable for every UK home.

What you keep should depend on:

• The number and ages of people in your household
• Allergies and previous reactions
• Existing health conditions
• Other medicines being taken
• Pregnancy or breastfeeding
• Whether anyone has difficulty swallowing tablets
• Conditions your family regularly experiences, such as hay fever or indigestion
• Whether child-appropriate liquids or other formulations are needed

A medicine being available without a prescription does not mean that it is safe for everyone. Ask a pharmacist for advice where somebody takes regular medication, has a long-term condition, is pregnant or breastfeeding, or has previously reacted badly to a medicine.

Always read the packet and patient information leaflet before taking a product. Check what the active ingredient is, what it is intended to treat and who should not use it.

Essential medicine categories to consider

The following categories provide a starting point rather than a mandatory shopping list. Buy only medicines that are appropriate for your household and that you understand how to use safely.

Pain relief and fever medicines

Painkillers are among the most useful medicines to keep at home, but different products have different cautions.

Paracetamol

Paracetamol is commonly used for pain and high temperature. It is available in adult and age-appropriate children’s formulations.

One of the most important safety points is to avoid accidentally taking paracetamol in more than one product. Many cold and flu remedies already contain it. Taking separate paracetamol at the same time could result in more than the recommended amount.

Always check the active ingredients, follow the stated dose and leave the required time between doses.

Ibuprofen

Ibuprofen is a non-steroidal anti-inflammatory drug, or NSAID. It can relieve pain and fever and may be particularly useful where inflammation is involved.

However, it is not appropriate for everyone. People with certain stomach, kidney, heart, bleeding or respiratory problems may need to avoid it or seek professional advice first. It should not be combined with other NSAIDs, such as naproxen, unless a healthcare professional has advised this.

Check the leaflet carefully, particularly if you take other medicines.

Aspirin

Aspirin has legitimate medical uses, but it should not be treated as a universal household painkiller.

It may be unsuitable for people with particular medical conditions or those taking certain medicines. Aspirin must not be given to anyone under 16 unless it has specifically been prescribed by a doctor.

Someone who takes aspirin regularly on medical advice should continue to follow their clinician’s instructions rather than changing their supply or dose independently.

Cold, flu and sore throat medicines

Cold and flu products may provide temporary relief from symptoms such as a blocked nose, cough, sore throat, aches or fever. Useful categories may include:

• Nasal decongestants
• Cough preparations
• Throat lozenges or sprays
• Saline nasal products
• Combination cold and flu remedies

The main preparedness concern is that many combination products contain several active ingredients. A single cold remedy may already contain a decongestant, painkiller or antihistamine.

Check the label before taking an additional painkiller. Some cold remedies contain paracetamol, ibuprofen, aspirin or codeine, so combining products can result in taking too much.

Decongestants are also unsuitable for some people and may interact with other medicines. Some nasal sprays should only be used for a limited period, as prolonged use can make congestion worse.

Ask a pharmacist if you are uncertain which formulation is appropriate.

Allergy medicines

Antihistamines can be useful for familiar, mild allergy symptoms, including:

• Hay fever
• Itching
• Mild hives
• Reactions to insect bites
• Allergy-related eye or nasal symptoms

Some antihistamines are more likely to cause drowsiness than others. Check the leaflet before driving, operating equipment or combining them with other medicines.

It is vital to distinguish mild allergy symptoms from anaphylaxis. Antihistamines are not a substitute for emergency treatment where someone has difficulty breathing, swelling of the throat or tongue, collapse, severe dizziness or other signs of a serious allergic reaction.

Where an adrenaline auto-injector has been prescribed, it should be used according to the person’s emergency plan, and 999 should be called.

Stomach and digestive medicines

Digestive illness can be particularly disruptive when travel is difficult or several household members are affected.

Indigestion and heartburn

Antacids and other indigestion products may be worth keeping where they are already used safely by somebody in the household.

Persistent, severe or frequently recurring symptoms should not simply be masked with repeated self-treatment. Ask a pharmacist or GP for advice.

Diarrhoea

Some adults may choose to keep a suitable non-prescription product for short-term symptom relief. These medicines are not appropriate in every situation or for every age group, so check the restrictions carefully.

Professional advice may be needed where diarrhoea is severe, persistent, accompanied by other worrying symptoms or affecting someone at greater risk of dehydration.

Oral rehydration salts

Oral rehydration salts are particularly useful because vomiting and diarrhoea can cause the body to lose water, sugar, salts and minerals.

The sachets are mixed with water according to the manufacturer’s instructions. They do not treat the cause of the illness, but they help replace what has been lost and reduce the risk or effects of dehydration.

Use the exact quantity of water stated on the packet rather than making the solution stronger or weaker.

Constipation and nausea

A familiar constipation product may be sensible where somebody in the household uses it occasionally and knows it is suitable.

Non-prescription options for nausea vary, and some can cause drowsiness or interact with other medicines. Rather than buying one speculatively, ask a pharmacist what would be appropriate for your circumstances.

Skin treatments

A small number of familiar topical products can be useful for minor skin problems. Depending on your household, these might include:

• Antiseptic cream or solution
• Mild hydrocortisone cream
• Antifungal cream
• Burn gel
• Bite or sting treatment
• Emollient or barrier cream

These products are not interchangeable. Check where they can be applied, whether they are suitable for broken skin and how long they should be used.

Hydrocortisone products, in particular, have restrictions relating to age, location and duration of use. Suspected infections, spreading redness, severe burns or symptoms that do not improve may need professional assessment.

Dressings, bandages, gloves and wound-care equipment belong in a separate first aid supply. See our guide to building a properly equipped prepper first aid kit for those items.

Eye care supplies

Useful eye-care supplies may include:

• Sterile saline pods
• Purpose-made eyewash
• Lubricating drops already used by a household member

Single-use sterile products can be convenient because they reduce the risk of contaminating a larger opened container.

Check how long eye drops can be used after opening, as this may be much shorter than the printed unopened expiry date. Contact lens solution should not automatically be treated as general eyewash.

Eye pain, changes in vision, chemical exposure or an embedded object require appropriate medical advice rather than repeated self-treatment.

Children’s medicines

Households with babies or children should keep appropriate formulations for their ages rather than assuming adult medicines can simply be given in smaller quantities.

Important points include:

• Check the age restrictions on every product.
• Check the concentration as well as the active ingredient.
• Keep the supplied measuring syringe or spoon with the medicine.
• Never use a kitchen teaspoon to measure liquid medicine.
• Keep adult and children’s products clearly separated.
• Check both expiry dates and after-opening instructions.
• Ask a pharmacist when you are unsure whether a product is suitable.

The NHS advises following the label and using the syringe or measuring device supplied with children’s liquid medicines. Aspirin should not be given to children under 16 unless prescribed, and ibuprofen may be unsuitable in some circumstances, including dehydration or chickenpox.

Avoid giving a child an adult medicine unless the packaging or a healthcare professional specifically confirms that it is appropriate.

What about prescription medicines?

This guide focuses mainly on non-prescription products. Regular prescription medicines require separate, individual planning.

Order and collect repeat prescriptions in good time, particularly before bank holidays, travel or forecast severe weather. Speak to the prescriber or pharmacist about any concerns involving availability, emergency supplies, controlled medicines, monitoring or refrigeration.

Do not obtain prescription-only medicines without proper supervision, and never share prescribed medication with another person.

Leftover antibiotics should not be stored for a future illness or given to somebody else. Use antibiotics only when prescribed or otherwise supplied on professional advice, and return unused quantities to a pharmacy.

For more detailed advice on repeat prescriptions, emergency supplies, travel and storage, read our guide to prescription medication preparedness.

Medicines and first aid supplies are different

Medicines include tablets, liquids, creams, sprays and drops that affect symptoms or bodily processes.

First aid supplies include plasters, dressings, bandages, gloves, tape, scissors and other items used to manage injuries.

They may be stored in the same cupboard, but separating them into clearly labelled categories makes both easier to find. It also reduces the chance of small medicine packets becoming buried beneath bulky dressings.

For injury-management equipment, read our guide to prepper first aid kits.

How much medicine should you keep?

There is no need to buy months or years of over-the-counter medicine.

A sensible reserve should be based on:

• The size of your household
• How frequently a medicine is genuinely used
• Its shelf life
• How easily it can be replaced
• Whether it has special storage requirements
• The likelihood of it being suitable when needed

Aim to cover familiar minor illnesses and short interruptions to pharmacy access. Buying one suitable pack and replacing it after use may be enough for products that are rarely needed.

Build your supply gradually. Do not clear pharmacy shelves, buy medicines simply because they are discounted or accumulate products that nobody in the household understands.

A large medicine cupboard is not automatically a well-prepared one. Expired, duplicated or unsuitable products create waste and increase the risk of mistakes.

How to store medicines safely

Correct storage helps protect medicines from damage and prevents accidental access.

Keep medicines in their original packaging

Original packaging preserves important information, including:

• The active ingredient
• Instructions
• Warnings and contraindications
• The expiry date
• Batch details
• Storage requirements

Keep the patient information leaflet and any measuring device supplied with the product. Avoid transferring tablets into unlabelled bags or combining different medicines in one container.

Choose a cool, dry and secure location

Follow the storage directions on the individual product. Most ordinary household medicines should be kept in a cool, dry, dark place, away from direct sunlight, heat and moisture.

Bathrooms are often a poor choice because humidity and temperature can fluctuate. Cupboards near a cooker, boiler, radiator or sunny window may also be unsuitable.

Medicines should be kept out of the sight and reach of children. A lockable medicine box or cupboard can be worthwhile where children, vulnerable adults or visitors may otherwise gain access. Child-resistant caps should not be treated as completely childproof. UK healthcare guidance commonly recommends keeping medicines in their original packaging in a cool, dry, secure place.

Refrigerate only when instructed

Some medicines need refrigeration, but most do not. Only place a medicine in the fridge when its packaging or leaflet tells you to do so.

Do not move a temperature-sensitive medicine to another location during a power cut without checking the manufacturer’s guidance or obtaining professional advice.

Be careful with travel supplies

A small medicine travel case can be useful for medicines genuinely needed away from home.

Keep products labelled and rotate them regularly. Do not leave medicines permanently in a vehicle, loft, shed or other place exposed to extreme temperatures.

Check expiry dates and rotate supplies

Inspect your medicine cupboard every three to six months and after any period of heavy use.

Check:

• Printed expiry dates
• Damage to packets or seals
• Whether liquids, creams or drops have been opened
• Any separate “use within” period after opening
• Whether labels and leaflets remain readable
• Whether the medicine is still suitable for your household

Writing the opening date on a bottle or carton can help where the usable life changes after opening. Medicines should be stored as directed, and some products have a shorter expiry once opened.

Move suitable products approaching their expiry into normal household use, then replace them if necessary. Do not rely on expired medicines as part of your emergency preparations.

Return unwanted, unused or expired medicines to a community pharmacy for safe disposal. Do not flush them down the toilet, pour them into a sink or pass them to another person.

Build your medicine supply gradually

You can create a practical household medicine supply in four stages.

Stage 1: Cover familiar everyday needs

Start with suitable pain and fever relief, oral rehydration salts and any digestive medicines your household already uses safely.

Stage 2: Prepare for seasonal illness

Consider suitable cold, flu, sore throat and allergy products, along with age-appropriate children’s formulations where needed.

Stage 3: Add household-specific products

Add only products that reflect genuine needs, such as a familiar hay fever medicine, an antifungal treatment or lubricating eye drops already used by someone in the household.

This does not mean buying medicines for conditions that have never been diagnosed or experienced.

Stage 4: Organise and maintain

Keep medicines in their original packaging, group them by category and store them securely. Add an expiry review to your household calendar.

Our guide to family medical preparedness explains how to organise medicines alongside medical records, prescriptions and other household health information.

Those who are new to emergency planning can also begin with the wider principles in Prepping for Beginners.

A practical medicine-cupboard action plan

A useful home medicine supply does not need to be complicated.

Start by:

1. Emptying and checking your current medicine cupboard.
2. Separating expired, damaged or unidentified items for safe disposal.
3. Listing the medicine categories your household genuinely uses.
4. Asking a pharmacist about contraindications or interactions.
5. Replacing missing products gradually.
6. Organising medicines by category in a secure location.
7. Scheduling a review every three to six months.

You can also add medicine planning to your family emergency plan and include appropriate household medicines within your wider home blackout kit.

Responsible preparedness means keeping a modest supply of medicines that are suitable, clearly labelled, safely stored and properly understood.
