What are the recommendations for oral contraceptive pills (OCPs) in patients with migraines?

Recommendations for Oral Contraceptive Pills in Patients with Migraines

Combined hormonal contraceptives (CHCs) are contraindicated in women with migraine with aura due to significantly increased stroke risk, while progestin-only contraceptives are safe alternatives for all migraine patients. 1

Risk Assessment for Migraine Patients

Migraine with Aura

• Women with migraine with aura have an independent increased risk of ischemic stroke (RR 2.16) 1
• This risk is significantly compounded by:
  • Combined oral contraceptive use (7-fold increased risk) 1
  • Age ≥35 years (RR 3.65) 1
  • Smoking (RR 9.03) 1

Migraine without Aura

• Migraine without aura alone is not a contraindication for CHC use 2
• However, careful assessment of additional stroke risk factors is essential:
  • Tobacco use
  • Hypertension
  • Hyperlipidemia
  • Obesity
  • Diabetes
  • Age >35 years

Contraceptive Recommendations by Migraine Type

For Migraine with Aura

• Absolutely avoid all combined hormonal contraceptives 1
• Safe options include:
  • Progestin-only methods:
    • Levonorgestrel IUD (Mirena) - preferred option 1
    • Etonogestrel implant (Nexplanon) 1
    • Progestin-only pills (POPs) 1
    • Depot medroxyprogesterone acetate injections 1
  • Non-hormonal methods:
    • Copper IUD
    • Barrier methods
    • Fertility awareness methods 1

For Migraine without Aura

• Progestin-only methods are first-line and safest options 1
• Combined hormonal contraceptives may be considered if:
  • Patient is under 35 years
  • Non-smoker
  • No other cardiovascular risk factors
  • No development of aura symptoms after starting CHCs 3

Monitoring Recommendations

• Regular follow-up every 2-3 months initially, then every 6-12 months 1
• Monitor for:
  • Changes in migraine pattern
  • Development of new aura symptoms (requires immediate discontinuation of CHCs)
  • Cardiovascular risk factors
  • Treatment effectiveness using headache calendars 1

Special Considerations with Contraceptive Use

Progestin-Only Pills

• Must be taken at the same time every day (within 3-hour window) 4
• May cause menstrual irregularities 4
• Small amounts pass into breast milk but generally considered safe for breastfeeding 4
• Potential drug interactions with:
  • Anticonvulsants (rifampin, barbiturates, phenytoin, carbamazepine, felbamate, oxcarbazepine, topiramate) 4
  • St. John's Wort 4

Combined Hormonal Contraceptives (when appropriate)

• Monitor for headache changes - discontinue if pattern becomes recurrent, persistent, or severe 5, 3
• May cause hyperkalemia with drospirenone-containing pills 3
• Contraindicated with uncontrolled hypertension 3
• Monitor prediabetic and diabetic women carefully 5, 3

Common Pitfalls to Avoid

1. Failing to distinguish between migraine with aura and without aura when prescribing contraceptives
2. Continuing CHCs when a patient develops new aura symptoms
3. Not considering additional stroke risk factors when prescribing CHCs to women with migraine without aura
4. Inadequate follow-up monitoring for changes in migraine pattern
5. Overlooking potential drug interactions, especially with anti-seizure medications commonly used for migraine prevention

By following these evidence-based recommendations, clinicians can help minimize the risk of serious adverse events while providing effective contraception for women with migraines.
