Common Medical Abbreviations

What should I engrave on my Medical ID? 

If you’re in an accident or have a medical emergency, then it’s imperative that your MedicAlert ID is engraved with your most critical medical information. First responders are trained to look for medical IDs. Therefore, your medical ID engraving should reflect the vital information that will help you get fast and accurate care in an emergency.

Deciding on what information to engrave can be challenging – especially if you if have more than one  medical condition, allergy, or medication. The American College of Emergency Physicians advises that you should list your information in the following order:

  • Allergies – but only those likely to cause anaphylaxis or severe reaction
  • Medications – any that will affect how you are treated in an emergency, such as blood thinners or immunosuppressants
  • Medical Conditions – your primary condition(s) – for example: heart disease, diabetes, epilepsy, dementia
  • Implanted Medical Devices – including pacemaker, ICD, LVAD, GCM
  • Other special instructions – i.e. no MRI, carries EPIPEN

Remember that only the most critical information goes on your ID. The rest of your medical history – including your current medications, past surgeries, vaccinations and more – is stored in your MedicAlert health profile. That’s the information that is communicated to first responders by our 24/7 emergency support team.

If you’re unsure what to engrave, talk to your physician. Also, our Member Care team is available Monday – Friday from 6am – 4:30 PM ET to help – call us on 800.432.5378.

What Is a medical abbreviation? 

When engraving your MedicAlert ID, it’s extremely important that you maximize the space on the emblem to communicate your most vital medical information. Also, it’s equally important to utilize the most common abbreviations used in the medical community. For instance, the condition ‘High Blood Pressure’ — also known as Hypertension — is very long, and would take up a lot of space on an ID if you need to include other information. Basically, by using the medical abbreviation of “HBP” or “HTN,” you communicate to emergency personnel that you have high blood pressure.  

Do first responders understand medical abbreviations? 

Yes – first responders, doctors, nurses, and other emergency response professionals use these abbreviations in their day-to-day work, so using them on your ID actually makes their job easier. Therefore when you use an accepted abbreviation, then EMTs don’t have to guess what your engraving means.

What are common medical abbreviations for medical alert bracelets?  

At MedicAlert, we’re continually adding new medical abbreviations to our vast database. As a result, our medical response team collaborates with partners in the medical community to understand, compile and diligently maintain a list of the most frequently used and recognized abbreviations. Of course, we want to ensure that you make best use of the space on your ID. But more importantly, we want to maximize the effectiveness of your engraving, so first responders have the information needed for a quick diagnosis.

Medications you should put on your ID

Some medications have a big impact on emergency treatment. For example, more than 50 million people in the U.S. take blood thinners to prevent blood clots from forming. As a result, an injury can result in much more bleeding than normal. If an emergency medical provider is aware you’re on blood thinners, then they’ll know to check for internal bleeding. If you take immunosuppressants, that’s also key info for those treating you. For example, here are several types of medications you should include on a medical id:


Blood Thinners / Anticoagulants

Apixaban (Eliquis)
Dabigatran (Pradaxa)
Edoxaban (Savaysa)
Rivaroxaban (Xarelto)


Calcineurin Inhibitors: Tacrolimus and Cyclosporine
Antiproliferative agents: Mycophenolate Mofetil, Mycophenolate Sodium and Azathioprine
mTOR inhibitor: Sirolimus, Torisel


Bethamethasone (Celestone)
Prednisone (Prednisone Intensol)
Prednisolone (Orapred, Prelone)
Triamcinolone (Aristospan Intra-Articular, Aristospan Intralesional, Kenalog)
Methylprednisolone((Medrol, Depo-Medrol, Solu-Medrol)
