Effects and side effects of migraine prophylaxis in children.

BACKGROUND

Migraine is the primary cause of headache in children. Most patients can be treated with lifestyle changes and acute attack prophylaxis. Prophylaxis should be considered when symptoms cause frequent school absenteeism, poor quality of life, recurring emergency room visits, and frequent analgesic use. We aimed to compare the efficacy and side effects of drugs used in migraine prophylaxis, chosen according to the clinical and/or demographic characteristics of the patients.

METHODS

One hundred eighty-six patients aged 6-18 years were evaluated and who were diagnosed with migraine according to The International Classification of Headache Disorders, 3rd edition beta version (ICH-3β). Propranolol, topiramate, flunarizine, and cyproheptadine were given as prophylactic treatment. The Pediatric Migraine Disability Assessment Score (PedMIDAS) score, severity, duration, and frequency of the headache attacks were evaluated from the medical records and pre- and post-treatment values were compared.

RESULTS

The median age of the patients was 14 years (range, 6-18 years) and the mean duration of headache was 29.6 ± 21.02 months. The mean PedMIDAS score was 29.9 ± 21.2 before and 14.9 ± 12.5 after treatment. Most reduction in the frequency of attacks was observed in the topiramate group. All four drugs significantly reduced the PedMIDAS score. The most common side effect was palpitations.

CONCLUSIONS

Significant improvement was found in PedMIDAS scores in all drug groups. Topiramate was found to be the most effective drug in reducing the frequency of attacks. All four drugs in this study may be utilized for migraine prophylaxis in terms of effectiveness and safety.
