Build a Year's Supply of First Aid and Medical Prep for Under $100

Medical problems during disasters are mostly mundane and mostly preventable: cuts that get infected, burns from improvised cooking, sprains from moving debris in poor light, dehydration, and above all the interruption of ordinary prescription medication. Serious medical preparedness for a household does not require a paramedic's budget — around $100 covers it. What it does require is the part people skip, which is opening the kit, learning to use three or four things in it, and keeping the medicines current.

The Honest Limitation: A Kit Nobody Has Opened Is Decorative

The commonest failure in medical preparedness is not an insufficient kit, it is an unopened one. A sealed 200-piece box bought four years ago has expired antiseptic, perished adhesive, batteries flat in the thermometer, and an owner who has no idea what is inside it. Under pressure, people use what they have handled before. So the value of this guide sits less in the shopping list than in three habits: open the kit and inventory it, learn a small number of skills properly, and check dates twice a year. Skills and currency beat contents.

Start With a Prebuilt Kit, Then Fix It

A 200-piece kit around the $35 mark is better value than assembling from scratch, because the bulk consumables — plasters, gauze, tape, wipes — cost more individually than the whole box does. But treat it as a starting point rather than a finished product. Most prebuilt kits pad the piece count with dozens of tiny plasters and skimp on the things that matter: large sterile dressings, a proper pair of trauma shears, nitrile gloves in quantity, and a triangular bandage. Buy the kit, tip it out on a table, count what is there, and top up the gaps.

What a Household Kit Should Actually Contain

The core list is short: plasters in several sizes, large sterile dressings and gauze, medical tape, a crepe or elastic bandage, a triangular bandage for slings, antiseptic wipes and cream, nitrile gloves in quantity, tweezers, blunt-ended scissors or shears, a digital thermometer, a CPR face shield, and burn gel or a burn dressing. Add a small torch and a notebook and pen, because recording times and observations matters if you eventually hand someone over to a professional. That is the whole kit, and almost all of it is cheap.

Medicines Are the Half That Expires

Keep a fortnight of over-the-counter medicines: paracetamol, ibuprofen, an antihistamine, oral rehydration sachets, an anti-diarrhoeal, and whatever your household routinely uses. Rehydration sachets are consistently the most underrated item on the list, because gastrointestinal illness is common when hygiene degrades and dehydration is what actually harms people. The NHS advice is simply to keep a well-stocked medicine cabinet rather than any specific number of days. Store medicines somewhere cool and dark — not the bathroom, which is humid — and check dates when the clocks change.

Prescriptions: The Real Vulnerability

For anyone on regular medication, the prescription buffer matters more than the entire first aid kit. Work with your GP or pharmacist to build toward a 30-day cushion by requesting refills at the earliest permitted point rather than the last, which accumulates a few days each cycle without anyone doing anything irregular. Keep a written list of every household member's medications, doses, prescribing doctor and pharmacy, in the document box and in each go-bag, since pharmacy records systems go offline exactly when you need a replacement. For refrigerated medicines such as insulin, read the patient information leaflet and ask your pharmacist — many in-use insulin products tolerate room temperature for around 28 days, but this varies by product and must never be guessed.

Skills Outrank Equipment

Every household should know how to perform CPR, place an unconscious breathing person in the recovery position, control significant bleeding with direct pressure, treat a burn with cool running water for twenty minutes, recognise anaphylaxis and use an adrenaline auto-injector, and clear a choking airway. A basic first aid course through the Red Cross or St John Ambulance costs roughly $50 to $80 and covers all of it in a day. That is the single highest-value spend on this page, and it is the one most consistently deferred because it cannot be ordered online and finished in an evening.

Bleeding Control, Realistically

Direct firm pressure with whatever clean absorbent material is to hand controls the overwhelming majority of bleeding you will ever encounter, and pressure held continuously beats pressure repeatedly lifted to check. Tourniquets and haemostatic gauze are genuinely effective for catastrophic limb bleeding, and they are also the items most often bought without training. If you buy them, get taught to use them, because a tourniquet applied wrongly does harm and one applied hesitantly does nothing. For most households, mastering pressure and elevation is the better investment.

Hygiene Is Preventive Medicine

Most disaster-related illness is preventable and comes down to hand hygiene and water. Alcohol hand sanitiser positioned where people actually eat, soap and enough stored water to wash with, and a plan for waste disposal prevent far more illness than any bandage treats. Wound care follows the same logic: a small cut cleaned properly with clean water and covered is a non-event, while the same cut left dirty during a week without power is how people end up needing antibiotics that are not available. Prevention is where the leverage is.

Kit Placement Matters as Much as Contents

One kit in a high kitchen cupboard is a single point of failure. Split it: a full kit in the kitchen where accidents happen, a compact kit in each go-bag, and a small kit in the car, where a meaningful share of injuries occur and help may be furthest away. Keep gloves and a torch with every one of them. Tell everyone in the household where each kit is, because the person who needs it is often not the person who packed it.

The Twice-Yearly Ten Minutes

Pair a review with the clock change so it never needs remembering. Open every kit, check dates on medicines and antiseptics, replace anything used since last time, test the thermometer, confirm adhesives have not perished, and update the medication list if prescriptions have changed. Ten minutes twice a year is the difference between a kit that works and a box of expired supplies that provides reassurance and nothing else — which is, in practice, the state of most household first aid kits.
