Best first-aid kits

How to choose

Buy for the injuries you'll really see

Expect small cuts more than anything dramatic. That's our judgment, not a measured fact. In US emergency room data on knife injuries from 1990 to 2008, 94% were lacerations, 66% involved fingers or thumbs, and only 1% of patients were admitted.² Look for finger and knuckle bandages, nonstick pads and rolled gauze rather than hundreds of tiny strips.

Ignore the piece count. A 298-piece kit that This Old House reviewed was more than half adhesive bandages, and the 326-piece Be Smart Get Prepared kit had the lowest score of 14 at OutdoorGearLab.^{1 15} Check for large dressings, rolled gauze, gloves and a CPR mask first. Several kits in OutdoorGearLab's comparison have no CPR mask.¹

Treat heavy bleeding as a separate purchase

For life-threatening bleeding, the 2024 American Heart Association and Red Cross guidelines call for direct pressure, followed by a tourniquet or wound packing where the wound allows it.¹⁶ Design matters if you buy a tourniquet. In a randomized trial published in 2019, 102 laypeople took a bleeding control class that taught the CAT, a windlass type, and then tried five types on a simulator. They got the CAT right 92.2% of the time, the SOF tactical tourniquet 68.6%, an improvised tourniquet 32.4%, and the elastic SWAT-T and RATS 11.8% each.³ The class favored the CAT, but a 2025 review of 10 studies also found elastic types did worse in every study that tested them.¹⁷ Don't count on an improvised one.

Training matters too. In a randomized trial of 465 people at a stadium, 88% applied a tourniquet correctly after a one-hour class, against 16% with no help.⁴ The skill fades: three to nine months later, only 54.5% of those retested could still do it.⁴ These were simulations, but the message is clear. Take a Stop the Bleed class before you spend more on trauma gear, and refresh it. The American College of Surgeons offers it online and in person.¹⁸

Choose a windlass model such as a CAT, SOF or SAM XT, and buy it from a known medical supplier.¹⁷ One case report describes a soldier who died after a counterfeit CAT-like tourniquet broke.¹⁹ A windlass takes grip strength, so one paramedic suggests a ratcheting model if your hands are weak.²⁰

Add your own medicines

Kits rarely carry what your household needs. Add aspirin, an oral antihistamine and any prescriptions. For adult chest pain, call 911 first. The AHA and Red Cross guidelines say an alert adult with chest pain that didn't come from an injury may chew aspirin, unless they're allergic or a clinician has told them to avoid it.²¹

If anyone at home takes opioids, add naloxone. FDA approved it for over-the-counter sale in 2023.²²

Don't pay extra for what the tap already does

Go to the tap for a burn, not to a kit's gel. In a registry study of 2,320 burn center patients in Australia and New Zealand, cooling with water was linked with an 18% shorter hospital stay and a 48% lower chance of ICU admission, with the benefit seen particularly up to 20 minutes.²³ That study looked at serious burns and didn't compare water with kit products, but it's a good reason to keep cool water running for as long as you can, up to about 20 minutes.

You probably don't need saline for everyday cuts either. In a Cochrane review, eight trials comparing tap water with saline couldn't show a clear difference in infection. That evidence is very weak, so it proves nothing either way, but tap water that's safe to drink is a reasonable choice.²⁴ Petroleum jelly is a fair stand-in when the ointment runs out. In a trial of 884 skin surgery patients, infection rates were 2.0% with white petrolatum and 0.9% with bacitracin, a difference that wasn't statistically significant. Eight petrolatum patients had staph infections against none on bacitracin, which was a significant difference. Four bacitracin patients developed an allergic skin reaction while no petrolatum patients did, which wasn't.²⁵ Those were surgical wounds in a clinic, not dirty cuts.

How many you need, and where to keep them

Keep one kit at home and one in each vehicle, which is Mayo Clinic's advice as cited by This Old House.¹⁵ FDA advises a cool, dry place for most medicines and names a damp bathroom cabinet as poor storage, so a hallway closet beats the bathroom.²⁶ Some medicines can't take high temperatures, so check the ones in a car kit more often.²⁶

Replace expired medicines, and watch for recalls

Once the date passes, FDA says there's no guarantee that a medicine is safe and effective.²⁶ A federal program found 88% of 3,005 tested lots could be extended at least a year, but those were government stockpiles, stored properly and retested.²⁷ A kitchen drawer gets no such checks, so replace what has expired.

Parts inside kits do get recalled, and the kit's name may not be on the notice. In a recall that began in December 2022, burn cream packets from one maker were pulled across several kits, including the CVS First Aid Home kit, for microbial contamination. FDA rated it Class I, its most serious level, and the recall has since ended.^{28 29 30} In January 2026, Acme United, the maker of First Aid Only, began a Class II recall of BZK antiseptic towelettes for manufacturing deviations. It covers First Aid Only 50-wipe boxes, 100-wipe boxes and bulk wipes by lot number, and the same recall lists wipes sold under other names, including Medi-First, Dynarex and Med-Nap.^{31 32 33 34} Class II means temporary or reversible harm is possible, or serious harm is unlikely.³⁰ FDA's record gives no reason beyond the deviations, showed the recall as ongoing in data updated October 28, 2026, and doesn't say whether those lots went into kits.^{31 34} If you own wipes like these, compare the lot numbers on your box or packets with FDA's list and throw out any match. Replace the wipes, not the whole kit.
