Aim

The purpose of this study was to evaluate both the effects of ibuprofen and/or acetaminophen for the acute treatment of primary migraine in children in or out prophylactic treatment with magnesium.

Methods

Children ranging from the ages of 5 to 16 years with at least 4 attack/month of primary migraine were eligible for participation the study. A visual analog scale was used to evaluate pain intensity at the moment of admission to the study (start of the study) and every month up to 18 months later (end of the study).

Results

One hundred sixty children of both sexes aged 5-16 years were enrolled and assigned in 4 groups to receive a treatment with acetaminophen or ibuprofen without or with magnesium. Migraine pain endurance and monthly frequency were similar in the 4 groups. Both acetaminophen and ibuprofen induced a significant decrease in pain intensity (P < .01), without a time-dependent correlation, but did not modify its frequency. Magnesium pretreatment induced a significant decrease in pain intensity (P < .01) without a time-dependent correlation in both acetaminophen- and ibuprofen-treated children and also significantly reduced (P < .01) the pain relief timing during acetaminophen but not during ibuprofen treatment (P < .01). In both acetaminophen and ibuprofen groups, magnesium pretreatment significantly reduced the pain frequency (P < .01).

Conclusions

Magnesium increased the efficacy of ibuprofen and acetaminophen with not age-related effects.
