Headache Management in Pregnancy

Introduction to Headache Treatment

• The American College of Obstetricians and Gynecologists recommends acetaminophen (paracetamol) as the first-line treatment for headache in pregnant patients due to its established safety profile during pregnancy 1, 2

Medications to Avoid

• The American Academy of Neurology advises against the use of triptans (sumatriptan, zolmitriptan, naratriptan), ergotamine and dihydroergotamine, topiramate (due to clear evidence of higher rate of fetal abnormalities), opioids (except in extreme circumstances), and butalbital-containing medications during pregnancy 1
• The use of topiramate during pregnancy is associated with a higher rate of fetal abnormalities, according to the American Academy of Neurology 1
• Butalbital-containing medications should not be used in the management of headaches during pregnancy due to potential risks, as recommended by the American College of Physicians 3

Evaluation of Headaches

• The American Headache Society suggests considering the possibility of idiopathic intracranial hypertension, especially if headaches are persistent or associated with visual changes, in pregnant patients 1
• New-onset headaches during pregnancy, especially with hypertension, should be evaluated for preeclampsia, as recommended by the American College of Obstetricians and Gynecologists 4, 5, 6
• Neuroimaging is required when headache is accompanied by focal neurologic deficits, failure to respond to initial therapy, non-orthostatic headache developing after initial orthostatic headache, headache onset >5 days after suspected dural puncture, or altered consciousness or seizures, especially in the postpartum period, as recommended by the American Academy of Neurology 7

Red Flags for Headache Evaluation

• The American Academy of Neurology recommends monitoring for red flags such as headache with focal neurological deficits, sudden onset severe headache ("thunderclap"), headache with fever or stiff neck, headache with visual disturbances, and headache with hypertension 7
• Delaying neuroimaging in patients with focal neurologic deficits or refractory headache is a potential pitfall, as emphasized by the American Academy of Neurology 7

Medication Safety During Breastfeeding

• Paracetamol (acetaminophen) is considered safe for breastfeeding mothers, with very low transfer into breast milk, and the amount ingested by the infant is significantly less than the pediatric therapeutic dose 2
• Ibuprofen is a safe option for breastfeeding mothers, with low levels in breast milk, and is extensively used during lactation, with a recommended dosage of 400-800 mg every 6 hours (max 2.4g daily) 2
• Diclofenac, Naproxen, and Ketorolac can be used during lactation, but with caution, due to their potential effects on the infant, with recommended dosages of 400-800 mg every 6 hours for Diclofenac, 275-550 mg every 2-6 hours for Naproxen, and short-term use (not to exceed 5 days) for Ketorolac 2, 8
• Sumatriptan is considered safe during breastfeeding, with low transfer into breast milk, and is effective for moderate to severe migraines that don't respond to NSAIDs, as noted by the American Academy of Pediatrics 8
• Aspirin, Codeine, and Opioids should be avoided or used with extreme caution due to their association with Reye's syndrome, variable metabolism, risk of infant sedation, sedation, respiratory depression, and dependency 2, 8

Non-Pharmacological Approaches

• Non-pharmacological approaches, such as relaxation techniques, adequate sleep hygiene, ice packs, avoiding known migraine triggers, and maintaining regular meals and hydration, should always be used as initial management and to complement medication, as recommended by the American Academy of Neurology and the American Headache Society 4, 5, 1
• Preventive treatment should only be considered in severe cases with at least three prolonged and debilitating attacks per month that don't respond to symptomatic therapy, with propranolol 80-160 mg once or twice daily (extended-release) as the first choice for prevention when needed, as recommended by the American Headache Society 4, 5

Patient Counseling and Monitoring

• Patients should always be counseled about medication risks before conception when possible, as recommended by the American College of Neurology 4
• Infants should be monitored for unusual drowsiness or poor feeding with any medication use 2
• The risk of medication overuse headache should be considered with frequent use of acute medications (≥15 days/month for ≥3 months) 3
