Contrary to common advice, don’t put something in a person’s mouth during a seizure. They cannot swallow their tongue. During a seizure, a person could clench their jaws and break something that is put in their mouth, like wooden or plastic utensils, or they could break their own teeth while clenching an object, causing a choking hazard. It’s OK to clear things from around their mouth, like wiping away saliva.
With some seizures, the person’s muscles become so stiff they might have difficulty breathing, so their lips may turn blue. The person isn’t choking on their tongue, says Dr. Shahid, but it can look like they aren’t getting air. Once the seizure passes, there will be an air exchange and their normal color will come back.
