UniShield ANSI Class B First Aid Refill with Medications Review (2026)
Is the UniShield ANSI Class B First Aid Refill with Medications the right reload for your cabinet?
Short answer: Yes — if you run a 3- or 4-shelf Class B cabinet and your program stocks OTC medications, this is the one-order reload that brings the whole station back to a full ANSI Z308.1-2021 Class B fill, medications included. It is the most complete refill in the First Aid Kit Refills collection and the natural restock for the larger cabinets we carry. If your station is a smaller 25-person Class A box, the far cheaper Urgent First Aid ANSI Class A Refill Kit is the better-matched buy.
Large wall cabinets have a specific failure mode: the box stays on the wall for a decade while the fill quietly degrades — bandage boxes empty out, and the dated items, especially OTC medications, expire on schedule whether anyone opens the door or not. The UniShield ANSI Class B First Aid Refill with Medications is built for exactly that reload: a complete Class B refill, including the medications most refill packs skip, sized to restock a 3- or 4-shelf cabinet without replacing it. This review positions it against the rest of the refill shelf, matches it to the cabinets in the First Aid Cabinets and Stations collection, and flags when a cheaper pack does the same job.
Editorial verdict: 4.4/5. At $169.95, the UniShield Class B Refill with Medications is the most complete single-order cabinet reload we stock — the only refill on our shelf built around a full Class B fill plus OTC medications. Expensive next to component refills, but far cheaper than replacing a $190-plus cabinet, and it eliminates the line-item audit entirely.

Pros
- Complete Class B reload in one order — no line-item audit against the ANSI list
- Includes OTC medications, the category most refill packs leave out entirely
- Sized for 3- and 4-shelf cabinets, the format where partial refills fall shortest
- Keeps a $140-$240 cabinet in service instead of replacing it
- Resets every expiration clock in the cabinet at once — one date to track
Cons
- $169.95 is a serious line item — overkill for small kits and Class A stations
- Medications add expiration-tracking obligations some programs deliberately avoid
- No listed manufacturer SKU, which complicates strict procurement paperwork
- If only two or three components are depleted, single-item restocks are far cheaper
Who the UniShield Class B Refill with Medications is for
- Facilities and EHS teams running 3- or 4-shelf Class B cabinets from the First Aid Cabinets and Stations collection on an annual full-reload cycle.
- Restaurants and food-service operators restocking a UniShield 4-Shelf Restaurant First Aid Cabinet where the fill turns over fast.
- Manufacturing and warehouse sites whose risk profile puts them in Class B territory under ANSI Z308.1-2021 rather than the lighter Class A fill.
- Programs that stock OTC medications and want them replaced on the same order and the same expiration clock as the rest of the fill.
What the UniShield Class B Refill does well
A full Class B reload in a single line item
Class B is the larger ANSI Z308.1-2021 fill — more items, in larger quantities, for higher-risk or more populated workplaces. Rebuilding a depleted Class B cabinet component by component means auditing dozens of line items against the standard's minimum list. This refill collapses that job into one order. Our OSHA first aid kit requirements explained reference covers what the Class B list actually demands and why OSHA's 29 CFR 1910.151 points employers to ANSI Z308.1 in the first place.
Medications included — the gap most refills leave open
Most refill packs stop at bandages, dressings, and antiseptics. If your program stocks OTC medications, those come from a second supplier on a second schedule — or they quietly expire in the cabinet. The UniShield pack is the one refill on our shelf explicitly built around a medication-inclusive reload, which is exactly what a fully-stocked break-room cabinet needs. Medications are FDA-regulated OTC drugs, so what goes in the cabinet is what the labels say — nothing more.
Sized for the big cabinets
A 78-piece 25-person pack disappears into a 4-shelf cabinet. This refill is scaled for the multi-shelf formats — the UniShield 4-Shelf Metal First Aid Cabinet, the MFASCO ANSI Class B 3-Shelf First Aid Cabinet, or the First Aid Only 90575 3-Shelf ANSI B+ Cabinet — where partial refills leave shelves visibly half-empty.
One expiration clock instead of a dozen
A full reload resets every dated item in the cabinet on the same day. That turns expiration tracking from a per-item spreadsheet into a single annual review date — a real administrative win for anyone managing multiple stations across a facility.
Where the UniShield Class B Refill falls short
The price demands the right container
At $169.95, this pack costs more than many complete kits. Feeding it into a 10- or 25-person box wastes most of the fill. If your station is a small Class A kit, the Urgent First Aid Class A refill at $24.95 or the MFASCO Class A refill pack at $43.99 do that job at the right scale.
Medications are not for every program
Some employers deliberately exclude OTC medications from workplace cabinets to avoid dispensing and expiration liability. If that is your policy, you are paying for components you will discard — the medication-free Urgent First Aid Class B Refill Kit, 50 Person is the cleaner match at $49.95.
Overkill for partial depletion
If the quarterly inspection shows two empty bandage boxes and everything else in date, a full reload is the wrong tool. Single-item top-ups from the Bandages and Wound Care collection handle partial depletion for a fraction of the cost; save this pack for the annual full reset or a genuinely stripped cabinet.

- Buy the Class A refill if the cabinet on your wall is a Class A unit like the UniShield 3-shelf.

Which cabinets this refill reloads
The natural pairings on our shelves: the UniShield 4-Shelf Metal First Aid Cabinet (the in-brand match), the UniShield 4-Shelf Restaurant Cabinet, the First Aid Only 90575 3-Shelf ANSI B+ Cabinet, the EVERLIT CARE 203SFAK100 3-Shelf Class B+ Cabinet, and the MFASCO Class B 3-Shelf Cabinet. A Class B fill is standardized, so the cabinet brand does not gate the refill. For choosing the cabinet itself, see our best first aid cabinets and wall-mount stations guide and the best workplace first aid kits guide.

Category context: where a medication-inclusive Class B refill fits
OSHA 29 CFR 1910.151 requires first aid supplies to be "readily available," and ANSI Z308.1-2021 defines what a compliant fill looks like — Class A for common workplace injuries, Class B for larger or higher-risk workforces. A multi-shelf cabinet is bought once; its fill is a consumable that turns over on usage and expiration. The upstream decision — which class, which format, how many stations across the facility — is the subject of our complete first aid kit buyer's guide. Between full reloads, component top-ups come from the Bandages and Wound Care collection and the Burn Care collection; trauma-level stations are a separate program covered by the Trauma Kits and Bleeding Control collection.
Total cost of ownership
Run the math against replacement. A UniShield 4-shelf restaurant cabinet is $239.95; the steel box lasts indefinitely while the fill turns over roughly annually in a busy kitchen. One $169.95 full reload per year — plus cheap mid-cycle top-ups like Band-Aid Flexible Fabric bandages or blue-detectable Curad knuckle bandages for food-service — keeps the whole station compliant without ever buying the box twice. Spread across a 50-plus-person site, that is a modest per-employee cost for a station that includes medications, and it beats discovering at inspection time that the cabinet contents expired two years ago.
Final verdict: 4.4/5
The UniShield ANSI Class B First Aid Refill with Medications is the right tool for one specific, common job: the annual full reload of a large Class B cabinet in a program that stocks OTC medications. It costs real money, but it replaces a procurement project with a single order. Buy this for 3- and 4-shelf Class B cabinets with medications in scope. Buy the Urgent First Aid Class B refill if medications are excluded from your program, or the Urgent First Aid Class A refill for smaller Class A stations.

UniShield Class B Refill with Medications — FAQ
Is the UniShield Class B Refill ANSI Z308.1-2021 compliant?
The pack is built as a complete ANSI Z308.1-2021 Class B refill, the larger of the two workplace fill classes. Match it to a cabinet that was purchased as a Class B unit — the class on the cabinet label determines the refill it needs. Our OSHA first aid kit requirements reference decodes the classes.
What makes a Class B refill different from a Class A refill?
Class B fills carry a broader assortment in larger quantities, designed for high-risk or more populated workplaces; Class A covers the common-injury baseline for offices and retail. Never restock a Class B cabinet down to a Class A fill — the cabinet was rated to the larger list.
Does the UniShield Class B Refill really include medications?
Yes — a medication-inclusive reload is this pack's defining feature. The medications are FDA-regulated OTC drugs used per their labels. If your workplace policy excludes medications from first aid stations, choose the medication-free Urgent First Aid Class B refill instead.
Which cabinets does the UniShield Class B Refill restock?
Any 3- or 4-shelf Class B cabinet, regardless of brand — including the UniShield 4-Shelf Metal cabinet, the First Aid Only 90575, and the EVERLIT CARE 3-shelf Class B+. The Class B fill is standardized across brands.
UniShield Class B Refill vs Urgent First Aid Class B Refill — which should I buy?
The Urgent First Aid pack at $49.95 covers the Class B fill without medications; the UniShield pack adds the medication layer and multi-shelf sizing at $169.95. Buy on whether medications are in your program's scope — see our Urgent First Aid Class B refill review for the other side of the comparison.
Is the UniShield Class B Refill worth $169.95?
Against a $189-$240 cabinet replacement, yes — the box is permanent and only the fill wears out. Against component-by-component restocking, it trades some cost for a one-order reload and a single expiration clock. For partially depleted cabinets, cheaper single-item top-ups win.
Can I use this refill in a Class A cabinet?
You can — a Class B fill exceeds Class A minimums — but you would be paying for quantity a Class A station does not require. The Urgent First Aid Class A refill or MFASCO Class A pack are the right-sized buys for Class A cabinets.
How often should a Class B cabinet get a full reload?
Inspect monthly or quarterly and top up as needed; run a full dated-item sweep at least annually. Because this pack includes medications — the shortest-dated items in any cabinet — most sites put the full reload on an annual cycle.
Do the medications in a first aid cabinet expire?
Yes. OTC medications carry expiration dates and must be replaced when they lapse — an expired medication shelf can fail an audit even when the bandage shelves are full. A medication-inclusive refill resets those dates in one order.
Does this refill satisfy OSHA requirements?
OSHA 29 CFR 1910.151 requires adequate, readily available first aid supplies and references ANSI Z308.1 as the benchmark fill. Keeping a Class B cabinet stocked to its rated class with a Class B refill is the standard way employers meet that expectation — details in our requirements reference.
Is this the right refill for a restaurant first aid cabinet?
It is the in-brand reload for the UniShield 4-Shelf Restaurant Cabinet. Food-service sites should also stock blue-detectable bandages like the Curad blue detectable knuckle bandages, which visual-inspection programs require and generic refills rarely emphasize.
What does the UniShield Class B Refill NOT cover?
It is a workplace first aid reload, not a trauma restock — no tourniquets or hemostatic dressings. Bleeding-control stations restock from the Trauma Kits and Bleeding Control collection, for example the RHINO RESCUE IFAK Refill Kit with CAT Gen-7. Eyewash is its own ANSI Z358.1 program — see our ANSI Z358.1 eyewash explainer.
Should I refill my cabinet or replace it?
Refill, unless the container itself is damaged. Steel cabinets outlive many cycles of contents; replacing a working cabinet to get fresh contents is paying twice for the box. Compare cabinet pricing in our best first aid cabinets guide if the box genuinely needs replacing.
Can I pair this refill with single-item restocks between reloads?
Yes — that is the standard rhythm: an annual full reload plus as-needed singles such as fabric bandages, island dressings, or burn dressings from the Burn Care collection.
Where does this refill fit in a new first aid program?
Choose the container first — headcount, risk class, and station count are walked through in the which first aid kit do you need guide — then buy the cabinet from the cabinets collection and put this refill on the annual reorder schedule from day one.
