Gauze, an antiseptic, tape, a pair of round-tipped scissors and not much else. That is what you genuinely need in a domestic first aid kit. The Spanish Red Cross draws an explicit distinction between the first aid kit — materials for treating minor wounds on the spot — and the household’s small medicine store, which is a different thing and is kept separately. Mixing the two is why most home kits end up as a messy drawer holding half a box of plasters and a bottle of something expired.
A wound care kit and a medicine store are not the same thing
The wound care kit covers what happens day to day: a cut while cooking, a child’s graze, a shoe rub. It needs dressings and instruments, not drugs.
The medicine store, by contrast, is the family’s usual set of medicines: painkillers and fever reducers for occasional use, an anti-inflammatory cream, an antihistamine. That content depends on the individual (allergies, long-term treatments, the age of any children in the house) and is worth reviewing with your pharmacist or doctor, because safe doses and combinations vary from person to person.
This article is about the first box: the wound care materials, which are the same for any household.
The essential wound care materials
Following the list the Spanish Red Cross recommends for a domestic kit, this is what should not be missing:
| Category | Contents | What it’s for |
|---|---|---|
| Wound cleaning | Saline solution | Flushing dirt away before disinfecting |
| Antiseptic | Povidone iodine or chlorhexidine | Preventing wound infection |
| Covering | Sterile gauze in several sizes | Covering wounds and burns |
| Fixing | Tape and plasters in several sizes | Holding gauze in place or covering small wounds |
| Bandaging | Bandages of various widths | Immobilising or compressing an area |
| Versatile bandaging | Triangular bandage (roughly 140×100×100 cm) | Improvised sling or covering large areas |
| Instruments | Round-tipped scissors and smooth tweezers | Cutting gauze or tape, removing splinters |
| Self-protection | Single-use gloves and alcohol wipes | Protecting your hands before treating someone else |
With this basic list you can handle the vast majority of minor wounds and knocks that happen at home.
Which antiseptic to choose
This is where most of the doubt arises, because most houses have accumulated several different bottles over the years.
Povidone iodine is a broad spectrum antiseptic suitable for small wounds, grazes and minor burns. It should not be used regularly or for long periods in children under 30 months, in pregnant women, in people with thyroid problems or in those taking lithium, because the iodine can be absorbed. Chlorhexidine is another common option, with a good safety profile on most superficial wounds.
Hydrogen peroxide, still very present in home kits, has lost its place in wound care: used repeatedly it can damage the very tissue trying to heal, so at most it makes sense for the first clean of a very dirty wound, not as a routine disinfectant.
One simple rule: pick a single antiseptic, check it hasn’t expired, and avoid mixing several different products on the same wound.
Where and how to keep it
- Somewhere every adult in the house knows, so nobody wastes time hunting for it in an emergency.
- Out of children’s reach, but with no lock or code: in a panicky moment, those mechanisms only get in the way.
- Cool and dry, away from bathroom humidity and kitchen heat, both of which degrade gauze and antiseptics early.
- In a closed, portable box, so it can be carried to another room or outside the house if needed.
Checking and restocking
A kit nobody checks stops being useful without you noticing. Go through it twice a year: check the expiry date on the antiseptic and on any opened saline, replace whatever has been used, and discard gauze or bandages whose sterile wrapping is torn, because once opened it loses sterility even if the material looks intact.
Variations depending on who lives there
The basic list is the same for any household, but it’s worth adapting quantities and sizes to the real situation:
- With small children, it makes sense to double up on small plasters and thin gauze, which get used far more often than the large ones.
- With older people or fragile skin, soft or hypoallergenic tape is worth having, as it comes off without damaging the skin.
- If there are pets, a couple of extra elastic bandages won’t hurt, although an animal wound should always be assessed by a vet or a healthcare professional.
- For the car or day trips, a reduced kit with the essentials (single-dose antiseptic, gauze, plasters, gloves) is more practical than carrying the whole house kit.
None of these variations changes the minimum contents, only the quantity and format of each item.
When to seek help
The home kit is for minor wounds. Seek medical attention or go to A&E if any of these appear:
- The wound won’t stop bleeding after 10 minutes of firm, direct pressure.
- It is deep, with widely separated edges, or affects the face, the joints or areas with a lot of tissue.
- It was caused by a rusty or very dirty object, or by an animal or human bite.
- Signs of infection appear over the following days: spreading redness, heat, pus or fever.
- It is an extensive burn, one with large blisters, or one affecting the hands, face or genitals.
- The person is not properly vaccinated against tetanus and the wound is deep or dirty.
