My FIL has a life-threatening penicillin allergy so he has to wear a silver bracelet that notifies any healthcare personnel just in case he needs treatment but is unconscious. Usually before medical treatment of any kind, it is important to take a patient’s medical history to determine if the patient has any conditions that contraindicated certain treatment regimes. For instance, my FIL can’t be given penicillin to treat any bacterial infection that he has because it has the potential to trigger a life-threatening allergic reaction in him. If you’ve got an allergy to penicillin or any other medication, it is worthwhile getting yourself some Medical Jewellery to notify healthcare workers just in case you need treatment but are unconscious and can’t provide a medical history. If you want to order one online, you can check out these bracelets or necklaces.
