Methemoglobinemia, or methaemoglobinaemia, is a condition of elevated methemoglobin in the blood. [2] Symptoms may include headache, dizziness, shortness of breath, nausea, poor muscle coordination, and blue-colored skin (cyanosis). [2] Complications may include seizures and heart arrhythmias. [3] [4] Methemoglobinemia can be due to certain ...
In some cases, a drug can cause the immune system to mistakenly think the body's own red blood cells are dangerous, foreign substances. Antibodies then develop against the red blood cells. The antibodies attach to red blood cells and cause them to break down too early. It is known that more than 150 drugs can cause this type of hemolytic anemia ...
Hypoxemia, methemoglobinemia, and hypoxia: Duration: 100-120 days (lifespan of red blood cells) Causes: Sulfur medications such as phenacetin, metoclopramide, dapsone, phenzopyridine, and trimethoprim-sulfamethoxazole; hydrogen-sulfide-producing intestinal bacteria, such as Morganella morganii: Risk factors: Pulmonary arteriovenous malformation ...
This is common in immunocompromised, elderly, and diabetic people. High blood loss can also come from the increased loss of blood during menstruation, childbirth, cancers of the intestines, and disorders that hinder the blood's ability to coagulate. [citation needed] Medications can have adverse effects and cause nutritional anemia as well.
In human blood a trace amount of methemoglobin is normally produced spontaneously; the enzyme methemoglobin reductase is responsible for converting methemoglobin back to hemoglobin. [23] [24] Methemoglobinemia can be hereditary but more commonly occurs as a side effect of certain medications or by abuse of recreational drugs. [25]
Cetacaine has been known to cause adverse effects in the patients it has been administered to. These include hypersensitivity in the form of anaphylaxis, dermatitis, erythema, pruritus which can lead to oozing and vesiculation. [4] There have also been accounts of rashes, edema, urticarial and other allergic symptoms as well as methemoglobinemia.
The CDC says there is no treatment of vaccines to tackle HMPV, but it did say medical care can be “supportive.” The Cleveland Clinic says treatments for the virus can include oxygen therapy if ...
Methylene blue is employed as a medication for the treatment of methemoglobinemia, which can arise from ingestion of certain pharmaceuticals, toxins, or broad beans in those susceptible. [11] Normally, through the NADH- or NADPH-dependent methemoglobin reductase enzymes, methemoglobin is reduced back to hemoglobin. When large amounts of ...
