ARLINGTON (CBS) — Arlington authorities are warning parents about a new TikTok craze that could be dangerous for kids. A combined statement from the police chief, superintendent, and health department said to watch out for the “Benadryl challenge.”

The challenge encourages kids to take a large dose of Benadryl because it can cause hallucinations.

Taking higher than recommended doses of Benadryl can lead to heart problems, seizures, coma, or death.
