Drinking mouthwash can have a range of harmful effects depending on the amount consumed. Here's what can happen:
- If a small amount is swallowed accidentally, it may cause mild symptoms such as nausea, upset stomach, or a mild queasy feeling. This usually passes quickly and is not likely to cause serious harm.
- Drinking larger amounts can cause alcohol intoxication because many mouthwashes contain significant ethanol (alcohol) concentrations (14% to 27%). Symptoms of intoxication include slurred speech, dizziness, impaired coordination, flushed face, restlessness, and difficulties standing or walking.
- Excessive ingestion can lead to alcohol poisoning, which is life-threatening. Symptoms include vomiting, diarrhea, stomach pain, headache, low body temperature, low blood sugar and blood pressure, rapid heartbeat, shallow breathing, sore throat, loss of coordination, unconsciousness, or coma.
- Other toxic ingredients in mouthwash, such as fluoride, menthol, chlorhexidine gluconate, methyl salicylate, and hydrogen peroxide, can cause gastrointestinal distress, organ damage, fluoride poisoning, throat irritation, and neurological problems when ingested in large quantities.
- In children, even a small amount of swallowed mouthwash can cause severe symptoms like low blood sugar, seizures, or respiratory issues.
If someone drinks mouthwash intentionally or swallows a large amount accidentally, it is imperative to seek emergency medical help immediately (call 911 or poison control at 1-800-222-1222). In summary, while swallowing a tiny amount of mouthwash by accident is unlikely to cause serious harm, drinking mouthwash in larger amounts is dangerous and can cause alcohol intoxication, poisoning, and other toxic effects due to its chemical ingredients. Medical attention is necessary in such cases to prevent serious health complications.
