Three-Part Question:
In [children with migraines], which [analgesic] provides the most effective [symptomatic relief in an acute attack]?
Clinical Scenario:
A 7-year-old boy is accompanied by his mother into ED. He is complaining of a moderate headache with nausea, and he appears pale and lethargic. You have ruled out meningitis and want to treat him for a migraine, but wonder which analgesic would be the most effective.

| Paracetamol versus Ibuprofen for the acute treatment of migraine headache in children. Vasudevan, P., Mishra, D. and Juneja, M. 2019 India | n=43 children (aged 6 to 12 years) with migraine without aura n=22 received oral paracetamol and n=21 received oral ibuprofen, at home, during an episode of acute migraine headache Pain‐freedom was defined as a score of zero in a 11‐point visual analogue pain scale (VAS), and pain‐relief was defined as >2‐point reduction from the baseline in the VAS |
Single-blinded, randomised controlled trial (Level 1b) | Pain freedom 2 hours after drug intake | No significant difference between paracetamol and ibuprofen groups (32% vs 28% respectively, p=0.77) | Data extracted from abstract. Small sample size. Not double-blinded. |
| Pain relief 2 hours after drug intake | No significant difference between paracetamol and ibuprofen groups (80% vs 80%, p=0.86) | ||||
| Side effects | No significant difference between paracetamol and ibuprofen with respect to drug side‐effects (13.6% vs 33.3% respectively, p=0.11) | ||||

Jeric, M., Surjan, N., Jelicic Kadic, A., Riva, N. and Puljak, L. 2017 Croatia | n=201 (RCTs) and n=variable (SRs) children <18 years requiring treatment for an acute migraine attack | Meta-analysis of 3 RCTs and 10 systematic reviews (Level 1a) | Pain-free at 2hrs | RCTs: Ibuprofen was superior to placebo (OR = 3.96 (95% CI, 1.78 to 8.82)) No significant difference between paracetamol and placebo (p>0.05), or ibuprofen and paracetamol (p>0.05) SRs: Ibuprofen superior to placebo (OR = 3.96 (95% CI, 1.78 to 8.82); n=225) No significant difference between paracetamol and placebo ((95% CI, OR 0.66-4.13); n=84), or ibuprofen and paracetamol ((95% CI, OR 0.96-5.71); n=81) | RCTs: The age range of the children varied between the studies: 4-16 years in one, 6-12 years in the second, and 6-18 years in the third. All three trials had unclear or high risk of bias (using the Cochrane risk of bias tool). Different definitions of pain relief were used in each RCT. Different doses of analgesia were used in each RCT. For many outcomes, data was only available from one source. SRs: Conclusions about the efficacy of ibuprofen and paracetamol were discordant. The methodological quality of the majority of included SRs, judged by the AMSTAR tool, was low. Inability to separate data from primary studies for prepubertal and pubertal children. |

| Effects of Acetaminophen and Ibuprofen in Children With Migraine Receiving Preventive Treatment With Magnesium. Gallelli, L., Avenoso, T., Falcone, D., Palleria, C., Peltrone, F., Esposito, M., De Sarro, G., Carotenuto, M. and Guidetti, V. 2013 Italy | n=80 children aged 5-16 years with at least 4 attacks/month of primary migraine Assigned in 2 groups to receive treatment with paracetamol or ibuprofen Assigned to receive at pain onset: paracetamol (PO 15 mg/kg, n=40) or ibuprofen (PO 10 mg/kg, n=40) A visual analogue scale was used to evaluate pain intensity |
Single-blinded, single-centre trial (Level 2b) | Time taken for decrease in acute pain | Significantly faster with ibuprofen (mean 31.95 +/- 1.7 mins) than with paracetamol (mean 48.5 +/-5.16 mins) (p=0.004; 95% CI, -27.54 to-5.54; t=-3.045) | No mention of randomisation. |
| Efficacy and Tolerability of Intravenous Valproic Acid in Acute Adolescent Migraine. Reiter, P., Nickisch, J. and Merritt, G. 2005 USA | n=31 children who received IV valproic acid (VPA) for acute migraine attack over an 18 month period Most children were considered to have failed some form of conventional migraine therapy prior to the VPA infusion Efficacy was measured using a 10‐point numerical pain scale Most children received a fixed VPA regimen consisting of 1000mg (first dose) infused at 50mg/min. If pain reduction was not sufficient, a second VPA dose of 500mg was provided |
Retrospective observational study (Level 2b) | Reduction in pain score from baseline (by end of clinic visit) | In children requiring only 1 dose: average = 39.8% reduction In children requiring 2 doses: average = 57.1% reduction | Data taken from 48 visits from 31 children, so representation was not equal between children. By its nature, this trial mostly included children with migraines severe enough to be resistant to conventional pain relief. Most children required concomitant IV dexamethasone and/or ondansetron to help alleviate symptoms of nausea and vomiting associated with migraine pain and/or VPA therapy, so unable to assess effect of drug on these symptoms. |
| Proportion of patients with major improvement (51-80% reduction) in or complete relief (81-100% reduction) of headache pain | 46.8% of all patients |
Author Commentary:
Paediatric migraine headaches are common, affecting around 3-10% of children. With a range of medication available off the shelves, it can be difficult for parents to know how best to manage acute episodes at home. Importantly, some parents may be unaware of the dangers of using aspirin in children under 16 years. Current guidelines suggest the use of simple analgesia (NSAID or paracetamol) as first-line medication, with escalation to a nasal triptan if ineffective.
In this review we have analysed the results of 2 meta-analyses and 4 original research studies. The emphasis in an acute migraine treatment plan should be on providing pain relief, reducing associated disability, and minimising drug side effects. With regards to first-line analgesics, ibuprofen was superior at providing complete or partial pain relief in children and had a faster onset of action than paracetamol. There is insufficient evidence in favour of paracetamol. For children and adolescents, triptans appear to be effective in providing pain relief. Sumatriptan was the preferred drug in this class. Triptans also reduced the risk of headache recurrence but were associated with an increased number of minor adverse side effects; in the case of intranasal triptans, this included taste disturbance, nasal symptoms, and nausea. Triptans should be made available in situations where ibuprofen has failed to provide symptomatic relief. There were no significant differences in the ability of these 3 drugs to reduce symptoms of nausea and vomiting. In comparison, IV valproic acid infusions had a delayed time to maximal effectiveness, and patients often required two sets of infusions to give sufficient pain relief. IV ketorolac was found to be ineffective.
Going forward, more double-blinded, randomised-controlled trials are warranted to stratify optimal treatments by age (i.e. adolescents vs. children), and more head-to-head comparisons of simple analgesics (paracetamol, NSAIDs) are necessary. The combination of sumatriptan plus naproxen sodium should be considered in future trials.

Bottom Line:
Ibuprofen is the most effective, quick-acting, and accessible first-line analgesic, with consistent pain relief shown across studies. Paracetamol should be considered if ibuprofen is contraindicated. Triptans are not only effective for symptomatic relief, but reduce the risk of headache recurrence and use of rescue relief. However, tolerance may be an issue as they are associated with more side effects, and only nasal preparations are approved for children <18 years. Other types of medication are available, which should be considered in refractory cases.
