Not every day
Family history in 70%
In young children often behavioural change
Throbbing or pulsatile in nature is common
Aura in 25%
Location bilateral and frontal more common in kids but can be anywhere
May have clear trigger
Sleepwalking, motion sickness, mouth ulcers and “growing pains” all common in children with migraine
Management
Consider medication overuse
Address any emotional mechanisms that provoke stress
Maintain a sound daily routine including regular meals, sufficient fluid intake, physical exercise and sleep
Many possible migraine triggers have been suggested, including hormonal, emotional, physical, dietary, environmental and medicinal factors. These triggers are very individual, and a headache diary can help to determine if there is a consistent trigger.
Acute Migraine
Paracetamol 15 mg/kg (up to 1000 mg) orally. Wait 4 to 6 hours before repeating the dose if needed (maximum dose 60 mg/kg [up to 4000 mg] in 24 hours).
Ibuprofen 5 to 10 mg/kg (up to 400 mg) orally. Wait 4 to 6 hours before repeating the dose if needed (maximum dose 30 mg/kg [up to 2400 mg] in 24 hours).
Trial going to sleep in a dark room.
Cold packs over the forehead or back of the skull (targeting the supraorbital and greater occipital nerves).
Hot packs over the neck and shoulders (targeting the innervation of the scalp).
Neck stretches and self-mobilisation.
Sumatriptan (Imigran) 10 to 20 mg intranasally. Wait at least 2 hours before repeating the dose if needed (no more than 2 doses in 24 hours). Patients may experience nasal stinging. 1
Rizatriptan (Maxalt) (child 20 to 39 kg: 5 mg; child 40 kg or more: 10 mg) orally (disintegrating tablet placed on tongue to dissolve). Wait at least 2 hours before repeating the dose if needed (no more than 2 doses in 24 hours).
Migraine Prophylaxis
Consider prophylaxis if headaches are:
Frequent and disabling enough to justify taking regular medication i.e. more than 3 to 4 migraine a month.
In a pattern where they are present on almost all days of a week in more than 2 weeks in a month.
Affecting social, school, or daily routine.
Under 10
Pizotifen (e.g. Sandomigran)
0.5 mg oral daily at night, gradually increase to 1.5 mg daily in divided doses. Maximum single dose at night, 1 mg.
Commonly used to prevent migraines in children.
Adverse effects include sedation and increased appetite.

Cyproheptadine hydrochloride (e.g. Periactin)
4 mg daily, can increase to 8 mg nocte.
Ensure adequate monitoring for adverse effects, e.g. sedation, paradoxical stimulation in children (e.g. agitation, hallucinations), increased appetite, weight gain.

Over 10
Beta-blockers
Propranolol – prevention of migraine:
Aged 2 to 12 years, oral, initially 0.2 to 0.5 mg/kg 2 to 3 times daily; usual dose 10 to 20 mg 2 or 3 times daily (maximum 4 mg/kg daily).
Aged 12 to 18 years, oral, initially 20 to 40 mg twice daily; maintenance dose usually 60 to 80 mg daily in divided doses.
Taper dose when stopping treatment to avoid rebound symptoms.
Contraindicated in patients with asthma.
Useful for both migraines and chronic daily headache.
Aged 2 to 18 years, oral, initially 0.1 to 0.25 mg/kg (maximum 10 mg) at night; gradually increase dose over at least 2 to 3 weeks according to response, up to 1 mg/kg (maximum 75 mg) at night. Consider rounding dose to the nearest 5 mg.
Generally 10 to 25 mg daily is sufficient. Specialists may prescribe higher doses but adverse effects often limit the dose.
Taper dose when stopping to avoid withdrawal symptoms.
Be aware of the potential for anticholinergic adverse effects such as constipation
