Headache due to analgesic abuse

Headache due to analgesic abuse is a type of headache, which is generated as a consequence of the consumption of analgesics in quantities greater than those recommended. It is a problem that affects 1% of the population and is more frequent in women and in people prone to migraine or tension headache.

The headache presents as a dull, bilateral, permanent, sometimes throbbing headache of mild or moderate intensity, of new onset or aggravating a previous headache.

It usually resolves or reverts to its previous pattern within two months after withdrawal of the causative drug, which is used as a criterion for diagnosis.

Frequent consumption of analgesics is considered when they are taken:

1. Ergotics more than 10 days per month
2. Triptans more than 10 days per month
3. Simple analgesics more than 15 days a month (e.g. paracetamol)
4. Combined analgesics more than 15 days per month
5. Opioids more than 10 days per month
