OBJECTIVE: Yawning is a frequent behavior with circadian effects. Sometimes, its frequency is very high and it is disturbing. However, there is no evidence-based treatment for yawning.METHOD: This is a case report of a man with severe yawning from about 2 years ago.RESULTS: Yawning reduced after taking propranolol.CONCLUSION: Current evidence suggests that propranolol may decrease yawning through its thermoregulation effect. It is worthwhile conducting controlled clinical trials to study whether propranolol is an effective treatment for yawning.
