What are the safest treatment options for migraines during pregnancy?

Safest Treatment Options for Migraines During Pregnancy

Paracetamol (acetaminophen) is the first-line and safest medication for acute migraine treatment throughout pregnancy, with non-pharmacological approaches always being the initial management strategy. 1

Non-Pharmacological Approaches (First-Line)

Non-pharmacological approaches should always be the initial management strategy for migraines during pregnancy:

• Relaxation techniques
• Adequate sleep hygiene
• Ice packs
• Avoiding known migraine triggers
• Maintaining regular meals and hydration 1

These approaches should be used both as initial management and to complement any required medication therapy.

Acute Treatment Options

First-Line Medication

• Paracetamol (acetaminophen): 1000 mg as needed
  • Safe throughout all trimesters 1, 2
  • Considered the preferred drug for acute treatment during pregnancy 2

Second-Line Medications (if paracetamol is ineffective)

• Sumatriptan:

  • Can be considered for sporadic use when paracetamol is ineffective 1, 2
  • Use with caution but evidence supports its relative safety 1

• NSAIDs (such as ibuprofen, naproxen):

  • Can be used during second trimester with caution 1
  • Should be avoided during first and third trimesters due to specific risks 2
  • Ibuprofen: 400-800 mg every 6 hours
  • Naproxen: 275-550 mg every 2-6 hours 1

For Severe Attacks

• Metoclopramide: Safe throughout pregnancy, particularly useful for associated nausea 1, 3

Preventive Treatment

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 1, 4.

First-Line Preventive Medication

• Propranolol: 80-160 mg once or twice daily (extended-release)
  • Considered the first choice for prevention when needed 1, 3

Second-Line Preventive Medication

• Amitriptyline: Low doses can be considered 4

Special Considerations and Red Flags

Important Monitoring Points

• New-onset headaches during pregnancy, especially with hypertension, should be evaluated for preeclampsia 1
• Women with migraine with aura should avoid combined hormonal contraceptives due to increased stroke risk 1

Red Flags Requiring Immediate Attention

• Headache accompanied by focal neurologic deficits
• Failure to respond to initial therapy
• Altered consciousness or seizures 1

Medications to Avoid

• Ergotamine derivatives (contraindicated) 5
• Butalbital-containing medications 1
• Aspirin (especially in third trimester) 1, 5
• Codeine and opioids (except in severe refractory cases) 1

Effect of Pregnancy on Migraines

Between 60-70% of women experience improvement in migraines during pregnancy, particularly during the second and third trimesters 3. Women with migraine onset at menarche and those with perimenstrual migraine are more likely to experience remission during pregnancy 3. This improvement is likely related to stable estrogen levels during pregnancy 6.

Preconception Counseling

Patients should be counseled about medication risks before conception when possible 1, 6. This counseling is essential to promote a safe and healthy pregnancy and should address maternal concerns and expectations about drug treatment 2.
