Clinic Anaphylaxis Kit: What to Stock and How to Keep It In Date

A clinic that gives injections or vaccines needs epinephrine 1 mg/mL on hand — at least three doses, according to the Immunization Action Coalition's standing-order template — along with the syringes, needles, and monitoring equipment to use it. Everything after that is a purchasing and housekeeping job: buy the right concentration, in package sizes you'll use before they expire, and check the kit on a schedule.

This guide covers what to stock, the one epinephrine mix-up worth designing out of your shelves, and how to keep the kit in date. It is not a treatment protocol. Your medical director's standing orders decide what is given, how much, and when.

What does a clinic anaphylaxis kit need?

The Immunization Action Coalition (IAC) publishes the standing-order template that many vaccination sites adapt. Its supply list for managing anaphylaxis in adults comes down to six groups (IAC, Item P3082, April 2023):

The template is blunt about the antihistamine: it relieves itching and hives, but it does not relieve airway obstruction, low blood pressure, or shock. Epinephrine is the first-line treatment, and the template states there are no absolute contraindications to it in anaphylaxis.

Settings differ. The Joint Task Force's 2023 anaphylaxis practice parameter notes that different community settings call for specific measures to prevent and treat anaphylaxis (Golden et al., 2023). Use the IAC list as the floor and your written protocol as the final word.

Which epinephrine goes in the kit: 1 mg/mL or 0.1 mg/mL?

The anaphylaxis kit takes epinephrine 1 mg/mL — ampules, vials, or autoinjectors. The 1 mg/10 mL prefilled syringe is a 0.1 mg/mL emergency syringe: the product that belongs on a crash cart or in a code box, not in the anaphylaxis kit. A clinic that keeps both needs to keep them apart.

Since May 1, 2016, USP labeling standards have removed ratio strengths such as "1:1,000" and "1:10,000" from single-ingredient injectable labels. The boxes now read 1 mg/mL and 0.1 mg/mL (FDA). The change happened because the ratios were easy to misread — 1:1000 and 1:10000 look nearly identical in small print. Ratios still appear on local anesthetics that contain epinephrine, such as lidocaine with epinephrine 1:100,000, so your staff will keep seeing both formats (APSF).

Patient-safety reporting programs have documented the error this invites: the 1 mg/mL concentration given where the 0.1 mg/mL concentration was intended (Pennsylvania Patient Safety Authority). Four habits design it out of a clinic:

• Store the two concentrations apart, in bins labeled in mg/mL. The Pennsylvania advisory recommends stocking a single concentration wherever possible.
• Don't shelve epinephrine next to ephedrine. The names look alike, both come in 1 mL vials, and the same advisory documents the two being swapped. It matters most in surgery and procedure settings that stock both.
• Keep 30 mL multiple-dose vials of epinephrine 1 mg/mL out of emergency kits and code boxes, as the National Coordinating Council for Medication Error Reporting and Prevention advises (NCC MERP).
• Reorder by NDC and concentration, never by "epi." If you aren't sure which NDC you have, the NDC lookup shows the product behind any code.

What about injectable antihistamines, steroids, and albuterol?

Those are protocol decisions. The IAC community-setting list names only an oral H1 antihistamine, and lists it as optional. A practice with its own medical director's protocol may add an injectable antihistamine, a corticosteroid, an inhaled bronchodilator, or IV fluids. Stock exactly what your written protocol names, in the forms it names. Nothing on that list replaces epinephrine.

How many doses should you keep, and in what package size?

Start from IAC's floor of three epinephrine doses onsite, then do the math by package:

• Ampules and single-dose vials are used once. Three doses means at least three, plus the syringes and needles to draw them up.
• Autoinjectors are commonly sold in two-packs. Three doses means two packs.
• A 10-ampule box is more than one kit for most small clinics. Before buying the bigger box for the lower unit price, ask what expiration date ships and how many you'll realistically use before then. The cheapest ampule is the one you use, not the one that expires in a drawer.

How do you keep the kit in date?

• Set a check schedule, write it into the protocol, and put a name on it. A kit that belongs to everyone gets checked by no one.
• Log every item: product, concentration, NDC, lot, expiration date, date checked, and initials.
• Restock right after any use, and recheck the whole kit at the same time — not just the item that was used.
• Leave epinephrine in its carton until it's needed. It is sensitive to light, so follow each product's labeled storage conditions (NCC MERP).
• Rotate stock. When a new order arrives, move the shorter-dated units to the front.
• Check the equipment with the drugs: light batteries, blood pressure cuffs, and the rescue mask.

What should you ask your supplier?

• What expiration date is on the lot you'll ship?
• Will the packing slip or invoice show the lot and expiration date for each item?
• Can you provide DSCSA transaction information and transaction statements for these purchases? (What those documents contain)
• Is this exact NDC in stock? If it isn't, tell me before a substitute ships — a different NDC can mean a different concentration or package size.

Stock your clinic's kit with Premier

Premier Pharma supplies licensed clinics, physician offices, and pharmacies, and every invoice lists the lot number and expiration date for each item. From this kit, we carry epinephrine 1 mg/mL ampules, an epinephrine auto-injector 2-pack, diphenhydramine injection, and albuterol inhalers. Open a free account — credential review typically takes 1–2 business days.
