Medical IDs for Blood Thinners, Coumadin, Warfarin

Each year, about 2 to 3 million people in the United States will need to take a blood thinning medication. Blood thinners are life-saving medication that help blood flow smoothly and prevent a blood clot. This type of medication can be taken orally or administered intravenously. Anticoagulants are a type of blood thinner and examples of those commonly used are Warfarin (generic name), Coumadin, Eliquis, Xarelto, and Jantoven.


"Always carry or wear identification that states you are taking warfarin. In an emergency, you may not be able to speak for yourself." - Cleveland Clinic

Medical conditions that may benefit from anticoagulants

According to WebMD and JAMA Network, anticoagulants or blood thinners can help treat the following health conditions:

  • Heart or blood vessel disease
  • Irregular heart rhythm
  • Lupus
  • Deep Vein Thrombosis (DVT)
  • Atrial Fibrillation
  • Stroke
  • Pulmonary Embolism
  • Congenital Heart Defect (CHD)

Most Common Reaction Risks of Taking Blood Thinners

Excessive bleeding is the most common reaction when taking blood thinners. Effective management of bleeding risks is critical. Any type of trauma is extremely dangerous if you’re taking a form of blood thinner. The presence of this medication in the body can increase the risk of internal bleeding after an injury. Although infrequent, bleeding caused by blood thinners can be very serious or life-threatening.

Other side effects can include:

  • Dizziness
  • Weakness/Fatigue
  • Complications from other drug interactions

"Another way for patients to lessen the consequences of anticoagulant-related bleeding is to wear a medical alert bracelet or carry a card in their wallet that indicates the specific anticoagulant they are taking and the dosage. This is especially important if the patient has lost consciousness or is not sufficiently cognitively aware to explain their situation to an ED physician." - Jeffrey I. Weitz, MD, FRCP(C), FACP

Communicating about Blood Thinners in an Emergency

No matter how cautious a person can be of avoiding blood thinner risks, accidents can still happen and excessive bleeding can still occur in emergencies. First responders need to know if you are taking blood thinners so they can work as quickly as possible to stop any life-threatening bleeding and also, to be alerted of blood clot risks. It is important to remember that being on a blood thinner also means that there is an underlying medical condition or a history thereof – first responders need to be made aware.

Medical identification jewelry is a simple tool to effectively communicate the presence of medical conditions and medications such as blood thinners.

"If you happen to be in an accident or require emergency surgery for some other reason, the warfarin will cause you to bleed more than usual. However, there are a number of ways that the effect of warfarin can be reversed and thereby prevent excessive blood loss. Obviously, those providing medical care to you in such a situation must know that you are taking warfarin in order to know that they need to reverse it." - Clot Care Online Resource

The reasons for using blood thinning medications vary from person to person. Because of this, it is important to choose a medical ID that can be custom-engraved with the wearer’s most accurate and updated health information. This can include the following:

1. Your name to quickly identify yourself in an emergency

2. Your medical conditions or allergies

3. Specific name of medications including the brand. Examples of anticoagulants are:

4. Medical device or implants i.e. pacemaker or defibrillator

5. Emergency contact number. This can be your family or doctor’s contact information.



“If you take an anticoagulant, you should consider wearing a medical ID so that emergency responders and medical doctors know how to best treat you in an emergency, or if you can’t share your medical history yourself. It is important that they not only work as quickly as possible to stop any life-threatening bleeding, but also that they understand you are at risk for blood clots.” - Sara Wyen, VT and PE blood clot survivor, Blood Clot Recovery Network
