Medical alert bracelets, also called medical ID bracelets, are common for those with severe epilepsy, diabetes, serious drug or food allergies, or dementia. A medical alert bracelet is an identification tag that includes lifesaving information about any medical conditions that require immediate attention should the wearer be in distress and unable to speak.
These bracelets are wearable tags and not to be confused with medical alert systems or devices, which can also be worn around the wrist. They're pieces of jewelry that inform emergency responders and medical professionals of certain medical conditions.
