Hormonal Headaches: Acute and Preventive Treatment
Acute Treatment
For menstrual-related migraine attacks, prescribe a triptan combined with an NSAID at the onset of headache pain to maximize therapeutic benefit. 1
First-Line Acute Therapy
- Sumatriptan 50–100 mg plus naproxen 500 mg (or ibuprofen 400 mg) taken simultaneously at migraine onset provides superior pain relief compared to monotherapy 1, 2, 3
- Sumatriptan demonstrates the strongest evidence for 2-hour and 24-hour pain relief (OR: 4.62 and 4.81 respectively) 2
- Subcutaneous sumatriptan 6 mg is preferred when severe nausea or vomiting prevents reliable oral intake 1
- Rizatriptan 10 mg is an alternative triptan with grade B evidence for menstrual migraine 3
- Mefenamic acid 500 mg alone has grade B evidence and is particularly useful in patients with concomitant dysmenorrhea 4, 3
Combination with Antiemetics
- Add metoclopramide 10 mg to the triptan-NSAID regimen when moderate-to-severe nausea is present to improve symptom control and drug absorption 1
Alternative Acute Options
- Lasmiditan shows efficacy comparable to sumatriptan for acute menstrual migraine but is reserved for patients who have exhausted other options 1, 2
- CGRP antagonists (gepants) such as rimegepant 75 mg or ubrogepant 50–100 mg are recommended for patients with cardiovascular contraindications to triptans or those who fail triptan therapy 1, 4
Medications to Avoid
- Never prescribe opioids or butalbital-containing products for acute menstrual migraine—these carry strong recommendations against use due to high risk of medication-overuse headache 1
Preventive Treatment
For women with predictable menstrual cycles and disabling perimenstrual attacks, initiate short-term prophylaxis with frovatriptan 2.5 mg twice daily starting 2 days before expected menstruation and continuing through day 3 of bleeding.
Short-Term Perimenstrual Prophylaxis (Grade B Evidence)
This approach is specifically indicated when attacks are predictable and occur primarily during the perimenstrual window (day -2 to day +3 of menstruation):
- Frovatriptan 2.5 mg twice daily is the most effective triptan for preventing headache recurrence during the perimenstrual period 2, 5, 3
- Naratriptan 1 mg twice daily is an alternative with grade B evidence 5, 3
- Transcutaneous estradiol 1.5 mg applied perimenstrually has grade B evidence but requires careful patient selection 5, 3
- NSAIDs (mefenamic acid 500 mg or naproxen 500 mg twice daily) taken perimenstrually can reduce attack frequency, particularly in women with dysmenorrhea 4, 5
Continuous Prophylaxis
When attacks occur both during menstruation and at other times of the cycle (menstrually-related migraine with additional non-menstrual attacks), or when short-term prophylaxis fails:
First-Line Continuous Prevention
Per the 2025 American College of Physicians guideline, initiate one of the following 6:
- Metoprolol or propranolol (beta-blockers)
- Valproate (antiseizure medication)
- Venlafaxine (SNRI)
- Amitriptyline (tricyclic antidepressant)
Second-Line Continuous Prevention
- CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab, or eptinezumab) or CGRP antagonists-gepants (atogepant or rimegepant) are recommended for patients who do not tolerate or inadequately respond to first-line agents 6, 2
- CGRP monoclonal antibodies demonstrate superior efficacy in reducing monthly headache days compared to triptans 2
Third-Line Continuous Prevention
- Topiramate is reserved for patients who fail both first-line agents and CGRP-targeted therapies 6
Hormonal Strategies
Combined Hormonal Contraceptives (CHCs)
- Extended-cycle or continuous CHC regimens (skipping placebo pills or limiting to 2 placebo days) can prevent estrogen withdrawal and reduce menstrual migraine frequency 4, 7
- This approach is suitable for women requiring contraception who have migraine without aura 7
- Absolute contraindication: Do not prescribe CHCs to women with menstrual migraine with aura due to unacceptable stroke risk 7
Special Populations
Lactating Women
- Propranolol 80–160 mg daily is the preferred first-line preventive agent with the most favorable lactation safety profile 8
- Contraindications to propranolol include asthma, heart failure, Raynaud's phenomenon, AV block, and depression 8
- Amitriptyline 10–100 mg nightly is second-line when propranolol is contraindicated, but requires specialist supervision and infant monitoring 8
- Avoid topiramate, valproate, and candesartan during lactation—these are explicitly contraindicated 8
- For acute treatment: paracetamol, ibuprofen, and sumatriptan are safe 8
Pregnancy
- Acetaminophen is the safest acute medication 1
- NSAIDs may be used before the third trimester 1
- Sumatriptan can be considered when benefit outweighs risk 1
Medication-Overuse Headache Prevention
- Counsel patients to limit acute medication use to ≤10 days per month for triptans and ≤15 days per month for NSAIDs to prevent medication-overuse headache 1, 8
- When attacks remain frequent despite optimal acute therapy, initiate continuous preventive treatment rather than escalating acute medication frequency 1
Clinical Pitfalls
- Menstrual migraine attacks are typically more severe, longer-lasting, and less responsive to treatment than non-menstrual attacks, requiring early and aggressive acute intervention 2, 4, 5
- Short-term prophylaxis requires predictable menstrual cycles; irregular cycles necessitate continuous prophylaxis 5
- The evidence for hormonal treatments beyond CHCs (GnRH agonists, SERMs, oophorectomy) is limited and these should not be first-line 7
- Always assess cardiovascular risk before prescribing triptans; use gepants in patients with coronary artery disease, uncontrolled hypertension, or prior MI 1
