Abstract

Rabbit syndrome is a distinct movement disorder characterized by involuntary, rapid, fine, rhythmic movements of the perioral muscles resembling the chewing movement of a rabbit . Exact mechanism of rabbit syndrome is unknown; however, it has been suggested to be due to basal ganglia dysfunction or hypersensitive dopamine D2 receptors . This is a report of two cases of rabbit syndrome, following application of 10% minoxidil foam. Case 1 A 25‐year‐old man presented with male pattern hair loss (MPHL), he was prescribed once a day application of half a capful of 10% minoxidil foam. After a week, he presented with complaint of vibration like sensation, over and around his lips. The tremors were rapid, rhythmic and regular, and last for about 30–40 minutes. Tremors appeared about half an hour following application of minoxidil. There was no associated tongue movement. He has a history of smoking five to six cigarettes per day.
