Medication Overuse Headache
Medication overuse headaches (MOH), also known as rebound headaches usually occur when analgesics are taken frequently to relieve headaches. Rebound headaches frequently occur daily and can be very painful and are a common cause of chronic daily headache. They typically occur in patients with an underlying headache disorder such as migraines or tension headaches that "transforms" over time from an episodic condition to chronic daily headache due to excessive intake of acute headache relief medications. MOH is a serious, disabling and well-characterized disorder, which represents a worldwide problem and is now considered the third-most prevalent type of headache. Population-based studies report the prevalence rate of MOH to be 1 to 2% in the general population, but its relative frequency is much higher in secondary and tertiary care.
