After discussing your symptoms, your doctor will perform a physical exam. The first step to treating a suspected case of cyanide poisoning is to identify the source of exposure.
This will help your doctor or other healthcare provider determine the appropriate decontamination method. In the case of a fire or other emergency incident, rescue personnel will use protective gear like face masks, eye shields, and double gloves to enter the area and take you to a safe location.
If you have ingested cyanide, you may be given activated charcoal to help absorb the toxin and safely clear it from your body.
Cyanide exposure can affect oxygen intake, so your doctor may administer percent oxygen via a mask or endotracheal tube. The cyanide antidote kit consists of three medications given together: amyl nitrite, sodium nitrite, and sodium thiosulfate.
The amyl nitrite is given by inhalation for 15 to 30 seconds, while sodium nitrite is administered intravenously over three to five minutes.
Intravenous sodium thiosulfate is administered for about 30 minutes. Hydroxocobalamin will detoxify cyanide by binding with it to produce nontoxic vitamin B This medication neutralizes cyanide at a slow enough rate to allow an enzyme called rhodanese to further detoxify cyanide in the liver. If you suspect you or a loved one is experiencing symptoms of severe cyanide poisoning, seek immediate emergency medical attention.
Your outlook will depend on the type of cyanide present, the dose, and how long you were exposed. Early diagnosis and treatment are key to reducing your risk of complications. Moderate levels of acute or chronic exposure may also be resolved with quick diagnosis and treatment.
In severe cases, symptoms are often sudden and life-threatening. Immediate emergency medical attention is necessary.

Discriminating between the two can be difficult. A stomach bug and food poisoning can be commonly…. Roundup is a popular weed killer with glyphosate as the main ingredient.
The use of Roundup is highly controversial, and some claim that it can cause…. Cyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore.
Cyanide gas is used to exterminate pests and vermin in ships and buildings. If accidentally swallowed, chemicals found in acetonitrile-based products that are used to remove artificial nails can produce cyanide when metabolized by the body.
Reports have indicated that during the Iran-Iraq War in the s, hydrogen cyanide gas may have been used along with other chemical agents against the inhabitants of the Kurdish city of Halabja in northern Iraq. How you could be exposed to cyanide You could be exposed to cyanide by breathing air, drinking water, eating food, or touching soil that contains cyanide.
Cyanide enters water, soil, or air as a result of both natural processes and industrial activities. When present in air, it is usually in the form of gaseous hydrogen cyanide. Smoking cigarettes is probably one of the major sources of cyanide exposure for people who do not work in cyanide-related industries.
How cyanide works The extent of poisoning caused by cyanide depends on the amount of cyanide a person is exposed to, the route of exposure, and the length of time that a person is exposed. Breathing cyanide gas causes the most harm, but swallowing cyanide can be toxic as well.
Cyanide gas is most dangerous in enclosed places where the gas will be trapped. Cyanide gas evaporates and disperses quickly in open spaces, making it less harmful outdoors. Cyanide gas is less dense than air; so it will rise. Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die. Cyanide is more harmful to the heart and brain than to other organs because the heart and brain use a lot of oxygen.
Immediate signs and symptoms of exposure to cyanide People exposed to a small amount of cyanide by breathing it, absorbing it through their skin, or eating foods that contain it may have some or all of the following signs and symptoms within minutes: Dizziness Headache Nausea and vomiting Rapid breathing Rapid heart rate Restlessness Weakness Exposure to a large amount of cyanide by any route may cause these other health effects as well: Convulsions Loss of consciousness Low blood pressure Lung injury Respiratory failure leading to death Slow heart rate Showing these signs and symptoms does not necessarily mean that a person has been exposed to cyanide.
Long-term health effects of exposure to cyanide Survivors of serious cyanide poisoning may develop heart, brain and nerve damage. How you can protect yourself, and what to do if you are exposed to cyanide Since breathing it is likely to be the primary route of exposure to cyanide, leave the area where the cyanide gas was released and get to fresh air.
Quickly moving to an area where fresh air is available is highly effective in reducing exposure to cyanide gas. If the cyanide gas was released outdoors, move away from the area where it was released. If you cannot get out of the area where the cyanide gas was released, stay as low to the ground as possible. If the release of cyanide gas was indoors, get out of the building.

If you think you may have been exposed to cyanide, you should remove your clothing, rapidly wash your entire body with soap and water, and get medical care as quickly as possible. There are some reports of use of rapid calorimetric paper test strips to confirm the presence of cyanide.
Before cyanide antidote can be administered, the patient must be removed from the cyanide-laden area, clothing removed, and skin washed with soap and water. If cyanide salts have been ingested, activated charcoal may prevent absorption from the gastrointestinal tract.
There are 2 major modalities of treatment: the cyanide antidote kit and hydroxocobalamin. Although recovery from a chemical attack is rare, victims may survive sub-lethal exposures, whether from ingestion, smoke inhalation, or exposure to cyanide-containing industrial products, such as carpet. Patients who are treated successfully for cyanide poisoning should be observed for development of long-term neuropsychiatric symptoms that are similar to symptoms experienced by survivors of cardiac arrest or carbon monoxide poisoning.
