The craze on TikTok reportedly encourages viewers to take large doses of the antihistamine to induce hallucinations. But the FDA warns that taking higher than recommended doses of the common over-the-counter (OTC) allergy medicine can lead to serious heart problems, seizures, coma, or even death.

On its website, the FDA said it is investigating reports and conducting a review to determine if additional cases have been reported.
