What are Medication-overuse Headaches (MOH)?
People who use acute pain-relief medicine more than two or three times a week or more than 10 days out of the month can set off a cycle called Medication-overuse Headaches (MOH). As each dose of medicine wears off, the pain comes back, leading them to take even more. This overuse causes your medicine to stop helping your pain and actually start causing headaches. MOH can occur with both over-the-counter and prescription pain-relief medicines. They can also occur whether you take them for headache or for another type of pain. Talk to your doctor if you think you have MOH.
