BACKGROUND AND OBJECTIVE: Genetics, hormone profiles and other physiologic factors can cause hair loss. Medication induced hair loss is an occasional side effect of many psychopharmaceuticals. It can reduce medication compliance if not discovered and treated. We present a 18 year old female with migraine headache who developed hair loss after 3 months of receiving topiramate treatment.

CASE REPORT: 18 year old female had been suffering from headache visited in psychiatric clinic. She agreed to a treatment with topiramate (50mg per day) for Migraine headache. 3 months later, the patient complained of significant hair loss. Topiramate tapered to 25 mg/day and stopped. Hair loss stopped after topiramate withdrawal. Two weeks after reintroduction of topiramate, hair loss developed again. The medication was stopped and hair loss stopped again.

CONCLUSION: Topiramate can cause hair loss. Although the condition is not life-threatening, a decrease in medication compliance can cause recurrence of the underlying disease. It is necessary to ask the patient at visits about it.
