Headaches can significantly disrupt daily life, and many people turn to painkillers for quick relief. However, this common solution can lead to a serious condition known as Medication Overuse Headache (MOH), also referred to as rebound headaches. In this blog, we'll explore MOH, how these headaches develop, the challenges in treating it and the treatment approach taken by The Headache Clinic to help sufferers of this type of headache.

Understanding Medication Overuse Headaches (MOH)

Medication Overuse Headache, or rebound headache, is a condition where frequent use of headache medication leads to more headaches. This issue often starts in people who regularly have migraines or headaches and use pain relief medication often. MOH creates a cycle where the short-term relief from medication leads to more severe headaches over time.

The Development Of Medication Overuse Headaches

Medication Overuse Headache (MOH) is due to the regular use of headache relief medications. This condition often develops in those who frequently rely on medications, including over-the-counter options like aspirin, paracetamol, and NSAIDs, as well as prescription medication such as triptans and ergotamines.


The key factor leading to MOH is the usage of these medications more than two to three times a week. This frequent use not only reduces the effectiveness of the medication but also intensifies the headache's frequency and severity, trapping the individual in a cycle of increasing medication dependence and worsening symptoms. Recognising this pattern is essential for the accurate diagnosis and effective treatment of MOH.

The Challenge With Treating MOH:

Treating Medication Overuse Headaches (MOH) can be quite challenging. If a person stops taking the headache medications that led to MOH, they may experience intense withdrawal symptoms. These symptoms, lasting up to 10 days, can include stronger headaches, nausea, vomiting, rapid heartbeat, sleep issues, restlessness, and feelings of anxiety.

Another major issue is that patients with MOH are often less responsive to preventive medications while they are still using the medication that caused the MOH. This makes treatment more complex and requires a careful and considered approach. The high relapse rate, as high as 73%, indicates that simply stopping the medication often isn't enough as the underlying headache problem still remains, leading many patients to start using the medication again, and restarting the vicious cycle.

The Headache Clinic's Approach To MOH Treatment

At The Headache Clinic in Johannesburg, South Africa, we have developed a different approach to treating MOH, which is highly successful, and in most patients avoids the problem of medication withdrawal symptoms.

We have determined that the pain in MOH, although it is more frequent and more severe than the original headache, originates from the same structures as the original headache. Our strategy therefore is to determine the source of the patient’s original headache pain. Once we have diagnosed where the pain is coming from, rational treatment, aimed at the source of the pain, can be undertaken. Our experience over thirty years of successfully treating head is that if the original underlying pain source is successfully treated, then the patient spontaneously stops the offending medication without experiencing withdrawal symptoms.

Opiate Overuse And How It Affects Treatment

The only exceptions to our treatment are opiates and opiate derivatives. Opioids are a special type of very potent pain-killer substances that produce morphine-like effects, and they are often prescribed for severe or chronic pain. However, their use requires careful monitoring due to their high potential for dependence and addiction.

The most prescribed opioids are:

OxyContin

Vicodin

Oxycodone

Percocet

Morphine

Lortab

Methadone

Fentanyl Patch

Hydrocodone

Tramadol

The issue with opioids is that they can unexpectedly make the pain worse. These types of medication can make patients more sensitive to pain if they are used for a long time to treat chronic pain. This makes treating the pain more difficult.

Before beginning treatment for their underlying condition, patients using opioids must first undergo detoxification. This step is crucial because the pain induced by opioid use can mask the positive effects of treatments aimed at the original source of the headache, whether it's arterial or muscular.

Conclusion

Medication Overuse Headache, or rebound headache, is a troubling condition stemming from the frequent use of pain relief medications. It's a cycle where short-term relief leads to more severe headaches over time. At The Headache Clinic, we've developed a successful approach that targets the root cause of the original headache, offering a path to recovery without the burden of withdrawal symptoms.
