Methylene blue is a medication that is administered by injection. Methylene blue is used in the treatment of methemoglobinemia, which is a condition that results in the patient's blood being unable to deliver enough oxygen to the body. This happens when methemoglobin, a form of hemoglobin that does not carry oxygen to tissues, is present in sufficient numbers to replace hemoglobin and starve the tissues of oxygen. Patients can have a series of symptoms resulting from the lack of sufficient oxygen.
Methylene blue works by binding to the excess methemoglobin molecules so that hemoglobin can work to deliver oxygen.
Patients may be born with methemoglobinemia or may acquire it at any time throughout their lives.
Methylene blue is only available from your doctor, and the injection should only be administered by a medical professional or under the supervision of a medical professional. It will be injected slowly, over the course of at least 5 minutes, through an IV.
