# Intestinomicina Dietary Supplement by Laboratorios Lopez: Safety Alert - Undeclared Drug Ingredient

**AUDIENCE**: Consumer, Health Professional

**ISSUE**: FDA is warning consumers not to use Intestinomicina, a drug product manufactured in El Salvador, because it contains the prescription drug ingredient, Chloramphenicol. Oral forms of Chloramphenicol were formally withdrawn from the United States market in July 2012 due to the risk of serious and life threatening injuries. The most serious and life-threatening injury associated with oral chloramphenicol treatment is bone marrow toxicity, which occurs when the body does not produce enough red blood cells, white blood cells, and/or platelets. Certain types of bone marrow toxicity are reversible; however, in rare circumstances it can lead to death.

**BACKGROUND**: Intestinomicina is marketed as a treatment for infectious diarrhea and acute gastrointestinal infections. Intestinomicina is labeled primarily in Spanish and lists the ingredient as “chloramfenicol palmitato,” or chloramphenicol in English, on the label. It can be found in tablet and liquid forms and is manufactured by Laboratorios Lopez. The product has been found in international grocery stores in the United States that feature South and Central American specialty foods and products.

The product label for Intestinomicina also lists antibacterial ingredients including Neomycin, an antibiotic often found in topical medications, and Sulfonamides, sometimes called sulfa drugs. Neomycin and sulfa drugs have the potential to cause a variety of adverse reactions, ranging from rashes and hives, to severe and life-threatening reactions. 

**RECOMMENDATION**: Consumers who have purchased this product should immediately stop taking it and consult with a health care provider.

Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:
