The Food and Drug Administration issued a warning over the use of Benadryl.
This comes as several teens have been hospitalized after taking part in the “Benadryl Challenge” on TikTok.
The FDA says taking too much Benadryl can lead to issues like seizures and heart problems.
It can also be fatal.
The FDA is asking TikTok to take down any videos of people taking part in the challenge.
