FDA Approves First Scorpion Sting Antidote (cont.)

Things to Know

The Arizona Poison and Drug Information Center says most stings to healthy, young adults can be managed at home with basic first aid and follow-up. Victims should

  • clean the site with soap and water
  •  apply a cool compress
  • elevate the affected limb to the same level as your heart
  • take aspirin or acetaminophen as needed for minor discomfort

If a child is stung or the victim experiences severe symptoms, go to a medical facility immediately. If the child is under 5 years old or if an older patient is experiencing more than minor discomfort, call the poison center at 1-800-222-1222.

Made by Instituto Bioclon in Mexico City, Anascorp may cause early or delayed allergic reactions in people sensitive to horse proteins. The manufacturing process includes steps to decrease the chance of allergic reactions and to reduce the risk of transmission of viruses that may be present in the horse plasma.

FDA determined Anascorp was effective based on the results of an initial placebo-controlled, double-blind study of 15 children with neurological signs of scorpion stings. During placebo-controlled, double-blind studies, some patients get the medicine being tested, and others get a placebo—and even the researcher doesn't know who gets which treatment. In the Anascorp study, symptoms disappeared within four hours in the eight subjects who received the antidote, but only one of the seven who received a placebo recovered so quickly.

In total, safety and efficacy data were collected from 1,534 patients in the studies led by the University of Arizona. The most common side effects of Anascorp were vomiting, fever, rash, nausea, itchiness, headache, runny nose, and muscle pain.

Experts say desert dwellers should know the symptoms of a scorpion sting and get treatment if severe symptoms develop. Severe symptoms include shortness of breath, fluid in the lungs, breathing problems, excess saliva, blurred vision, slurred speech, trouble swallowing, abnormal eye movements, muscle twitching, thrashing of the arms and legs, trouble walking, and other, uncoordinated muscle movements.
