Medication overuse headache (MOH) is a secondary headache disorder that develops when acute headache medications are used too frequently, paradoxically increasing headache frequency and severity. It affects an estimated 1–2% of the general population and up to 30–50% of patients attending specialist headache clinics, making it one of the most common causes of chronic daily headache.
Which medications cause MOH and at what thresholds: simple analgesics (paracetamol, aspirin, NSAIDs) cause MOH when used 15 or more days per month; triptans, ergotamines, and combination analgesics cause MOH at 10 or more days per month; and opioids carry the highest risk, causing MOH at just 10 days per month with rapid escalation of tolerance. The mechanism involves central sensitisation — repeated medication exposure alters pain-processing pathways in the brainstem, lowering pain thresholds and creating a vicious cycle where more medication produces more headache, which prompts more medication use.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for chronic headache.
Recognition requires asking about acute medication frequency in every headache patient. Patients often do not realise their medication is contributing to the problem. Structured withdrawal is the cornerstone of management: abruptly stopping the overused medication, with or without short-term transitional medication (such as a corticosteroid taper or greater occipital nerve block) to ease the withdrawal period. During withdrawal, headache frequency initially increases before improving — patients must be counselled that this worsening is expected and temporary, typically improving within 2–4 weeks. Initiating a preventive medication during withdrawal improves outcomes. At Kathmandu Neurology Clinic & Cognitive Center, Dr. Jitendra Prasad Yadav (NMC 8029) screens for medication overuse at every headache consultation and manages structured withdrawal at Durbar Marg, Opposite of Yak & Yeti Hotel.

Frequency may improve with systematic evaluation of types, contributors, and individualized planning, but outcomes vary.
Using pain medication on 10+ days per month can trigger daily headache. Reduction or cessation under medical supervision may help break this cycle.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Migraine typically presents as moderate-severe throbbing headache with nausea and/or sensitivity to light or sound, worsened by routine activity. Duration 4–72 hours. Dr. Jitendra Prasad Yadav (NMC 8029) uses ICHD-3 criteria plus your headache diary (frequency, aura, medication days) and red-flag screen to distinguish …
Stress does not cause migraine alone but lowers threshold and increases frequency, especially with irregular sleep and frequent analgesic use. Dr. Jitendra's approach: diary for frequency/medication days, sleep regularity, hydration, caffeine review, and comorbidity screening (anxiety, insomnia, neck pain). The clinic …
