Migraine is underdiagnosed and undertreated in SA. If you have received a chronic migraine diagnosis, you may already have been managing disabling headaches for years without adequate medical aid support. This guide addresses the coverage questions.
Does My Medical Aid Have to Cover This?
Migraine and chronic migraine are not CDL conditions. There is no standalone PMB benefit for chronic migraine management. Treatment is funded through the standard medicine benefit (MSA or ATB for medications), specialist consultation benefit (neurologist), and exceptional-needs authorisation for CGRP mAbs and Botox.
Acute, severe migraine causing neurological symptoms (e.g., hemiplegic migraine, status migrainosus lasting more than 72 hours) may qualify as a PMB emergency. New-onset severe headache with neurological signs also warrants emergency assessment — CT/MRI for exclusion of secondary causes is PMB-covered as an emergency diagnostic event.
Step 1: Rule Out Medication Overuse Headache
Before starting any new preventive therapy, your neurologist will assess for medication overuse headache (MOH) — a paradoxical worsening of migraine driven by too-frequent use of acute medications (triptans taken on 10+ days/month, simple analgesics on 15+ days/month). MOH is very common in the chronic migraine population and must be addressed before preventive therapy will be effective.
Withdrawal from overused medication often causes temporary worsening before improvement. Your neurologist will guide this process. Understanding this upfront prevents the incorrect conclusion that preventive treatment is "not working."
Oral Preventive Therapy: Start Here
Oral preventive medications are first-line and must be adequately trialled before CGRP mAbs or Botox will be approved. What "adequate trial" means: at least 3 months at a therapeutic dose.
The most commonly used options: - Topiramate 50–100mg daily: Most widely prescribed; monthly cost ~R350. Common side effects: cognitive slowing, word-finding difficulty, appetite suppression and weight loss. - Amitriptyline 10–75mg nocte: Inexpensive; particularly useful if poor sleep is a co-symptom. - Propranolol 40–160mg daily: Good evidence; avoid in asthma or resting bradycardia.
If two oral preventives have failed (no meaningful reduction in migraine days after 3 months at therapeutic dose), document this formally with your neurologist — this is the step-therapy requirement for CGRP mAb or Botox authorisation.
Triptans: Getting Access Right
Triptans (sumatriptan, rizatriptan, zolmitriptan) are the most effective acute migraine treatments. Most schemes impose monthly quantity limits — commonly 9–12 tablets per month. For patients with frequent episodic migraine, this is often inadequate.
If your triptan monthly limit is insufficient: - Ask your neurologist to write a letter requesting an increased monthly quantity with clinical justification (documented attack frequency, diary data) - Consider splitting between two triptan types if the limit is per-product rather than per-class
Using triptans on more than 10 days per month triggers medication overuse headache — a reason to escalate preventive therapy rather than solely increasing triptan access.
Getting Botox Funded
Botulinum toxin (PREEMPT protocol) for chronic migraine requires exceptional-needs authorisation from most schemes. Your neurologist submits: - Confirmed chronic migraine diagnosis - Documentation of two or more failed oral preventive trials - Monthly headache frequency (diary data preferred) - PREEMPT protocol specification (dose, injection sites, 12-week interval)
Botox provides chronic migraine prevention for approximately 12 weeks per cycle; three treatment cycles per year. The neurologist's procedure fee (R2,000–R4,000 per session) is in addition to the Botox product cost.
Getting CGRP Monoclonal Antibodies Funded
CGRP mAbs (fremanezumab/Ajovy, erenumab/Aimovig, galcanezumab/Emgality) are highly effective preventive biologics. Approval requires: - Confirmed chronic migraine (15+ days/month, 3+ months) - Failure of at least two oral preventive agents at adequate dose and duration - Monthly headache frequency and disability impact (MIDAS or HIT-6 score) - CGRP mAb selection and proposed dosing
Once approved, CGRP mAbs are self-administered by subcutaneous pen injection at home — monthly or every three months depending on the product. They are significantly more convenient than the Botox protocol, which requires an in-rooms procedure every 12 weeks.
Verify SAHPRA registration status for the specific CGRP mAb with your neurologist — availability may differ from international markets.
Migraine and Hormones
Perimenstrual migraine (migraine triggered by the drop in oestrogen at menstruation) is extremely common. If your migraine is predominantly perimenstrual: - Discuss continuous combined oral contraceptive therapy with your gynaecologist (eliminates the hormonal drop) - Short-course perimenstrual naratriptan or frovatriptan (longer-acting triptans) as mini-prophylaxis

Understanding Your Neurologist's Role vs GP
Once chronic migraine is diagnosed and a preventive regimen is established, ongoing management can often be shared between your neurologist and GP:
- Neurologist: Annual review (or more frequent if on Botox — every 12 weeks); management of CGRP mAb exceptional-needs; Botox administration; advice on treatment-resistant disease
- GP: Routine prescription renewal of oral preventives and triptans; initial management of acute attacks; monitoring for medication overuse
Shifting to GP-led routine management once stable preserves your neurologist consultation benefit for specialist input when disease changes, when Botox is being administered, or when escalation is needed. Confirm with your GP whether they are comfortable managing chronic migraine maintenance.
Pregnancy and Migraine
Migraine in women often changes with pregnancy — many women experience improvement due to stable oestrogen levels, though a minority worsen. Important medication considerations: topiramate and valproate are teratogenic and should be avoided in pregnancy. Discuss your entire preventive and acute medication list with your neurologist and obstetrician before conception or as early as possible in pregnancy.
