![]() The enzyme uses thiosulfate to convert the cyanide. However, if there is too much cyanide, then this enzyme is overwhelmed. There is an enzyme that converts cyanide to a form that can be eliminated from the body. The body can be routinely exposed to small amounts of cyanide and needs to be able to handle this small amount on an everyday basis. The third drug in the kit, Sodium Thiosulfate, helps the body detoxify the cyanide. Finally, the cost of the kit is more than $300, costly for large services with many ambulances. ![]() It tends to disappear from stocks as a result. In addition, there are security concerns as Amyl Nitrate, which is supplied in ampoules for inhalation before an IV can be started, has been reported to be used for aphrodisiac purposes. They are not in the typical formulary for EMS providers, and the most common cyanide exposure for EMS is likely to be a house fire when they should not be used anyway. The creation of methemoglobin in this situation would likely be fatal.Īmyl Nitrite and Sodium Nitrate create methemoglobinemia, and can be given if there is no exposure to carbon monoxide. However, if the victim has been exposed to carbon monoxide from a house fire, they will have even less functional hemoglobin as carboxyhemoglobin, which is created from exposure to CO, cannot carry oxygen either. In patients that have been exposed to cyanide only, this would be fine - the body can survive with only 70 percent of hemoglobin functioning to carry oxygen. Normally we want to create about 30 percent methemoglobin. The downside of creating this form of hemoglobin, called methemoglobin, is that it cannot carry oxygen. This will pull the cyanide out of the mitochondria of the cells and allow the resumption of normal energy production. ![]() One of the treatments for cyanide poisoning is to turn some of the hemoglobin in the body into a form that will attach to cyanide. Next, there is Sodium Nitrate for IV administration. First, there is Amyl Nitrite for inhalation. ![]() These are in short supply - often there is only one or two available to each emergency department. It is also known as the Lilly Kit, Pasadena Kit or the Taylor Kit. You may report side effects to FDA at 1-80.In the hospital, a common treatment is the Cyanide Antidote Kit. Call your doctor for medical advice about side effects. This is not a complete list of side effects and others may occur. Pain, swelling, or irritation of your skin where the injection was given. Red coloring of your urine (may last 2 to 5 weeks) or Severe shortness of breath, wheezing, gasping for breath, cough with foamy mucus Ī light-headed feeling, like you might pass out orĭangerously high blood pressure (severe headache, blurred vision, buzzing in your ears, anxiety, confusion, chest pain, shortness of breath, uneven heartbeats, seizure).Ĭommon side effects of Hydroxocobalamin may include: Call your doctor if you have a rash that lasts longer than 4 weeks.Ĭall your doctor at once if you have a serious side effect such as: This rash should go away without treatment. You may develop an acne-like skin rash within 1 to 4 weeks after you are treated with hydroxocobalamin. Get emergency medical help if you have any of these signs of an allergic reaction: hives chest tightness, difficulty breathing swelling of your face, lips, tongue, or throat. Make sure any doctor caring for your pregnancy or your baby knows you have received this medication. In an emergency situation, it may not be possible before you are treated with hydroxocobalamin to tell your caregivers if you are pregnant or breast feeding. You should not breast-feed after you have been treated with hydroxocobalamin. It is not known whether hydroxocobalamin passes into breast milk or if it could harm a nursing baby. However, the benefits of treating cyanide poisoning may outweigh any risks posed by hydroxocobalamin, for both you and your baby. It is not known whether hydroxocobalamin will harm an unborn baby. If you have ever had a severe allergic reaction to hydroxocobalamin, Vitamin B12, or cyanocobalamin ( Nascobal, Cobolin, Cyomin, and others).įDA pregnancy category C. Kidney disease (or if you are on dialysis) or If possible before you receive hydroxocobalamin, tell your caregivers if you have:
