Patients should stop using Intestinomicina — an oral treatment for infectious diarrhea and other acute gastrointestinal infections — because it contains chloramphenicol, the FDA has warned. Oral chloramphenicol was banned in the U.S. earlier this year because it increases risk for bone marrow toxicity and other life-threatening conditions.

Intestinomicina, which is made in El Salvador, is sold in tablet and liquid forms and may be found in stores in the U.S. that sell Central and South American specialty products.

In addition, the FDA notes that Intestinomicina contains neomycin and sulfonamides, which also can cause life-threatening adverse reactions.
