The Role of Muscle Relaxers in Headache Management
Muscle relaxers are a class of drugs primarily approved for the short-term treatment of acute musculoskeletal conditions. However, they are not typically considered a first-line therapy for most types of headaches. Their use in headache management is considered 'off-label' because the FDA has not approved them for this purpose. Due to limited evidence of effectiveness and potential side effects, they are sometimes used when other treatments fail or when muscle tension significantly contributes to the pain.
Are Muscle Relaxers Effective for Different Headache Types?
Muscle relaxers are not a standard treatment for headaches like migraine. Some off-label use exists for types like chronic tension headaches and managing medication overuse headaches or occipital neuralgia. Muscle relaxers are generally categorized into antispasmodics and antispastics. Common antispasmodics include tizanidine (Zanaflex), cyclobenzaprine (Flexeril), methocarbamol (Robaxin), and metaxalone (Skelaxin). Baclofen (Lioresal) is an antispastic sometimes explored for migraine.

Muscle Relaxer Comparison
| Feature | Tizanidine (Zanaflex) | Cyclobenzaprine (Flexeril) |
|---|---|---|
| FDA-Approved Use | Spasticity from MS, spinal cord injury | Acute muscle spasms from injury |
| Off-Label Headache Use | Chronic migraine prevention, rebound headache management | Chronic tension headache, migraine with neck tension |
| Evidence for Headache | Some studies show benefit for chronic daily headache, but evidence is mixed | Limited evidence from modern clinical studies; some anecdotal reports |
| Common Side Effects | Drowsiness, dry mouth, dizziness, muscle weakness | Drowsiness, dry mouth, dizziness, constipation |
| Addiction Potential | Lower potential compared to some others | Moderate potential for abuse and dependence, especially with long-term use |
| Duration of Use | Short-term recommended due to side effect risks | Short-term use with rest and physical therapy |
Side Effects, Risks, and Considerations
Using muscle relaxers for headaches, particularly long-term, involves various risks. Common side effects include drowsiness and dizziness, which impair driving and are worsened by alcohol. Some muscle relaxers like carisoprodol and cyclobenzaprine have a potential for abuse and dependence; abrupt discontinuation can cause withdrawal. Overusing these medications can lead to medication overuse headaches. Muscle relaxers can interact with other CNS depressants, increasing the risk of severe sedation. Tizanidine carries a risk of liver toxicity. Certain health conditions and pregnancy/lactation may contraindicate their use.
Conclusion: Weighing the Evidence
Muscle relaxers are not a standard treatment for headaches despite some exploration for chronic tension headaches and migraines. The evidence for their long-term effectiveness is limited and mixed, with risks like dependence and sedation often outweighing potential benefits. Preferred treatments include NSAIDs, triptans, and CGRP antagonists, which have stronger evidence. Always discuss alternative options and risks with a healthcare provider before considering muscle relaxers for headaches. They should be used judiciously, usually for short periods, and under medical supervision.
