Medication overuse headaches
Why OTC drugs are dangerous.
Medication overuse headache (MOH), also known as rebound headache, is a type of headache that develops as a result of excessive use of headache medication. It typically occurs when medication is used more frequently or in higher doses than recommended, and the headache returns as the medication wears off.
Causes
The exact cause of MOH is not fully understood, but it is believed to be related to changes in the brain and the body's response to medication overuse. Certain medications, such as opioids, triptans, and ergotamines, are more likely to cause MOH than others.
Symptoms
The primary symptom of MOH is a headache that occurs daily or almost daily and is often described as a dull, persistent pain that affects both sides of the head. Other symptoms may include nausea, vomiting, and sensitivity to light and sound.
Treatment
Treatment for MOH typically involves discontinuing the use of the headache medication and using other non-medication strategies for pain management, such as relaxation techniques, stress management, and lifestyle changes. In some cases, a doctor may recommend a short course of steroids or other medication to help break the cycle of medication overuse and manage the symptoms of MOH.
Complications
In most cases, MOH is not associated with serious complications. However, it can be a very frustrating and debilitating experience, and it may interfere with daily activities and quality of life. Long-term use of certain headache medications, such as opioids, can also lead to dependence and addiction, which can have serious health consequences. It is important for individuals who experience MOH to discuss their symptoms with their healthcare provider to develop an appropriate treatment plan and prevent further headaches.
