Rebound Headaches Causes
Nearly any pain reliever can contribute to rebound headaches. But some medications are more likely to lead to rebound headaches than are others.
* Simple pain relievers. Common medications such as aspirin, acetaminophen and ibuprofen may contribute to rebound headaches — especially if you exceed the recommended daily dosages.
* Combination pain relievers. Over-the-counter pain relievers that contain a combination of caffeine, aspirin and acetaminophen are common culprits. This group also includes prescription medications such as Fioricet and Esgic, which also contain the sedative butalbital.
* Migraine medications. Various migraine medications have been linked with rebound headaches, including ergotamine and triptans (Imitrex). Interestingly, the ergot dihydroergotamine appears to have a lower potential for leading to this problem.
* Opiates. Painkillers derived from opium or from synthetic opium compounds include combinations of codeine and acetaminophen. These can lead to rebound headaches as well.
Daily doses of caffeine — from your morning coffee, your afternoon soda, or any pain reliever or other product containing this mild stimulant — may fuel rebound headaches as well. Read product labels to make sure you’re not wiring your system with more caffeine than you realize.
Risk factors
Anyone who has a history of migraine headaches, tension-type headaches or other chronic headaches is at risk of developing rebound headaches from the overuse of pain relievers. Your risk increases if you use combination analgesics, ergotamine, or triptans 10 or more days a month or simple analgesics more than 15 days a month — especially if this regular use continues for three or more months.
Rebound headaches aren’t typically an issue for people who use pain medications on a daily basis to treat conditions such as arthritis.
