Sanford Guide vs Johns Hopkins ABX Guide: cost and which one to buy

Half the price. That is the headline, and it is exact: the Johns Hopkins ABX Guide is $39.95 a year and Sanford Guide Antimicrobial All Access is $79.99 a year, both read off the vendors' own product pages in September 2026. If you came here to settle which antimicrobial reference is cheaper, that is settled. Most of the comparisons still ranking for this question were written in 2015 and 2016 and quote $29.99 for both, and neither figure has been true for years.

Whether the cheaper one is the right one is a different question, and it depends on what you already carry in your pocket. Here is what each subscription actually includes, the two ways the prices are misleading, and a short decision rule for a hospitalist, an urgent care clinician, an NP or a pharmacist buying with their own money.

Sanford Guide vs Johns Hopkins ABX Guide: published prices in September 2026

Two things in that table decide more purchases than the headline does. First, Hopkins sells one thing: $39.95 buys the app and the website together. Sanford splits its access, so the like-for-like comparison against Hopkins is All Access at $79.99, not the $34.99 mobile SKU that makes Sanford look cheaper on a search results page. Second, the Sanford mobile price is displayed against a struck-through higher figure, which means it is a current promotional price rather than a list price, and it can move. The full rate card, including institutional licensing, is on our Sanford Guide subscription cost page, and the Hopkins figures and free preview are covered on the Johns Hopkins ABX Guide cost page.

What $39.95 buys from Hopkins

The ABX Guide is written by Johns Hopkins Medicine and delivered by Unbound Medicine, which also runs Nursing Central and the Davis Drug Guide. The product page promises monthly updates, four indices (diagnosis, pathogen, management and vaccine) and expert comments and analysis on the entries, and the subscription covers the app and any web browser. There is a free 30 day trial through the app, and a free web preview that exposes roughly a tenth of the topics without an account, which is a genuinely useful way to check whether the writing style suits you before paying.

The bundle math is simple. The four-guide bundle is $89.95, so the HIV, Diabetes and Psychiatry guides cost $50 combined on top of ABX, about $16.67 each. If one of those three is relevant to your practice, the bundle is good value. If none is, it is $50 you did not need to spend. Group rates for hospitals, schools and pharmacies exist but Unbound does not publish them.

One practical detail: because the platform is Unbound's, your login, renewal and support run through Unbound Medicine, not through Johns Hopkins. That matters when the subscription auto-renews and the charge shows up under a name you do not immediately recognize.

What $79.99 buys from Sanford

Sanford Guide describes itself as born as a grand rounds handout over 50 years ago, and the pocket book is still the thing most clinicians picture. All Access is the digital version of that book plus the parts a book cannot do. The vendor lists continuous updates, app and web access, and a set of interactive tables and tools: a vancomycin AUC24 calculator and dosing calculators for creatinine clearance and colistin, among others. The apps run offline once the content is downloaded, with connectivity needed only for updates and external links, which is the feature hospital-based clinicians tend to cite when they explain why they pay double.

The Web Edition at $59.99 drops the app. The mobile SKU at $34.99 drops the browser. If you only ever consult it on a phone, the mobile subscription puts Sanford within $5 of Hopkins, but it is the promotional price, and you lose the desktop access that most people end up wanting on a ward computer. Sanford also sells a separate Stewardship Assist product for institutions that want to push their own antibiogram and local recommendations into the same app, and that is quoted, not listed.

Is the Sanford Guide worth it at twice the price?

It is worth it if you use the calculators and the tables, and it is not if you only read the treatment entries. That is the honest dividing line. The ABX Guide is an infectious disease reference you read; Sanford All Access is that plus arithmetic you would otherwise do in a separate app. If your renal dosing and vancomycin math already live somewhere else, you are paying $40 a year for tables you will rarely open, and Hopkins is the rational choice. If you want the reference and the calculators in one place with the same login, Sanford is the one product that does it, and $40 a year is not much to pay for not switching apps at 2 a.m.

Format is the other reason people pay the difference. Sanford is organized the way the print guide always was, by clinical syndrome and pathogen with dense comparative tables, and clinicians who trained on the book find it faster. Hopkins reads more like a set of monographs with commentary. Neither is better in the abstract; the free Hopkins preview and the screenshots on Sanford's product page will tell you in ten minutes which one you think in.

Sanford Guide vs Johns Hopkins for a hospitalist, urgent care or an NP

Before buying either, ask your medical library. Hospital systems and residency programs commonly license one of the two, and sometimes both, and the personal subscription a lot of clinicians carry duplicates access they already have through the institution. That check costs nothing and it is the single most common way people waste money in this category.

If you are buying personally, the rule that fits most US clinicians is this. Hospitalists, ICU clinicians and hospital pharmacists who dose vancomycin and aminoglycosides and adjust for renal function all day tend to get their money's worth from Sanford All Access, because the calculators are used, not decorative. Urgent care, primary care and most nurse practitioners, whose antimicrobial questions are mostly which agent and for how long, get the same answer from Hopkins at half the price. Infectious disease specialists usually keep both and treat the $120 a year as trivial against the questions they field.

Whichever you choose, put a note on the anniversary date. Both subscriptions renew automatically, Sanford through an optional auto-renewal you accept at purchase and Hopkins through Unbound's store, and both charges land on a card under a company name that is not the name on the app. A practice that carries four or five clinical subscriptions per clinician loses track of these fast, which is the case for running the cards through something that flags the charge the moment it posts rather than discovering it on a statement in March.

What neither guide checks for you

Both are references you open with a question already in mind. Neither looks at the prescription you are about to sign and tells you, unprompted, that the fluoroquinolone interacts with the antiarrhythmic already on the patient's list, that the creatinine clearance you did not recalculate makes the standard dose wrong, or that a documented allergy blocks the obvious choice. To get that, you have to know to look, in several separate places, and the errors that slip through are the ones nobody thought to check.

Prescriber.io is built for that moment. Enter the antimicrobial and the scenario, and the drug interactions, contraindications and allergy blockers, renal and hepatic dose adjustments and guideline-based alternatives arrive together in one card with cited sources, for you to review, verify and sign. It is decision support for a licensed clinician, not a replacement for either guide, and it runs alongside whichever one you keep. If renal adjustment is the part of antimicrobial prescribing that costs you the most time, our guide to antibiotics that are safe in renal failure and the free creatinine clearance calculator are the two pages on this site that clinicians pair with a Sanford or Hopkins subscription most often.

How the two compare with UpToDate and Lexidrug

People also ask whether an antimicrobial guide is necessary at all if they already have UpToDate. The answer is that they overlap but do not replace each other. UpToDate has infectious disease topics and the Lexidrug drug database, and it publishes no individual price, so the comparison is between a quote and $39.95 or $79.99; what a personal UpToDate subscription includes is on our UpToDate subscription cost page. The dedicated guides are faster to a regimen and to a local-resistance-aware choice, which is why ID-heavy services keep one even inside a hospital that licenses UpToDate. Lexidrug at $29.99 a month is a drug reference, not an infectious disease reference, and it is the wrong purchase if the question you are asking is which antibiotic rather than how much of it.

Frequently asked questions

Is the Johns Hopkins ABX Guide cheaper than the Sanford Guide?

Yes. The Johns Hopkins ABX Guide is $39.95 a year for app and web access, and Sanford Guide Antimicrobial All Access, the equivalent app-plus-web subscription, is $79.99 a year, so Hopkins is exactly half the price. Sanford's mobile-only subscription is $34.99 at a promotional price, but it excludes browser access, so it is not a like-for-like comparison.

Which is better, Sanford Guide or Johns Hopkins?

Neither is better outright. Sanford All Access includes interactive dosing tables and calculators, including a vancomycin AUC24 tool, and follows the syndrome-and-pathogen layout of the print guide. Hopkins is a monographs-with-commentary reference with monthly updates and a free preview of about a tenth of its topics. Clinicians who use the calculators tend to pick Sanford; clinicians who mainly need the regimen tend to pick Hopkins.

Does the Sanford Guide have a free trial?

The Sanford Guide apps are free to download but the content is a paid subscription, and the vendor does not advertise a free trial on its All Access product page. Johns Hopkins offers a free 30 day trial through its app and a free web preview without an account. If trying before buying matters to you, Hopkins is the easier one to test.

Can I get either guide through my hospital?

Often, yes. Both vendors sell institutional licenses, Sanford by individual, workstation, facility and enterprise-wide tiers and Hopkins through group rates, and neither publishes an institutional price. Ask your medical librarian which one the system already holds before paying personally; many clinicians discover they already have access to one of them through the library.

Do I still need an antimicrobial guide if I have UpToDate?

Many clinicians keep one anyway. UpToDate covers infectious disease and includes Lexidrug drug content, but the dedicated guides are faster to a regimen and are built around syndrome, pathogen and local resistance. Since UpToDate publishes no individual price and the guides cost $39.95 to $79.99 a year, the guide is usually the cheaper and more specific addition rather than the replacement.
