Researchers show muscle relaxants are ineffective and may be unsafe for low back pain

Australian researchers have found muscle relaxants are largely ineffective and potentially unsafe when treating low back pain, despite being widely prescribed. Published today in the British Medical Journal, research by Neuroscience Research Australia (NeuRA) and UNSW has shown muscle relaxants might reduce pain in the short term, but the effect is too small to be considered clinically meaningful, and there is an increased risk of side effects. The research also showed that the effects of long-term muscle relaxant use remain unknown.

Low back pain is a major global public health problem and has been the leading cause of disability worldwide for the past 30 years. Though a prevalent…

Patients age <65 years who can tolerate the sedating effects may also benefit from a non-benzodiazepine muscle relaxant (such as cyclobenzaprine. Cyclobenzaprine is a reasonable first choice drug, based on the volume of evidence.

 Muscle Relaxants: Sedatives Often Under the Radar

Muscle relaxants encompass medications with different mechanisms of action—many of which have been used for decades. Yet most are sedating, can have significant side effects, and can interact with opioids and other substances to worsen CNS and respiratory depression.

We agree with the authors’ conclusion that combination of an NSAID and a SMR does not improve acute LBP outcomes more than an NSAID plus placebo, regardless of age, sex, baseline functional impairment, or history of LBP.

A Guide To The Best Natural Muscle Relaxers

While pharmaceuticals can provide much-needed relief, they can also come with potentially dangerous side effects, making natural muscle relaxers an appealing option.

Choosing a Skeletal Muscle Relaxant

Skeletal muscle relaxants are widely used in treating musculoskeletal conditions. However, evidence of their effectiveness consists mainly of studies with poor methodologic design. In addition, these drugs have not been proven to be superior to acetaminophen or nonsteroidal anti-inflammatory drugs for low back pain.

Inappropriate Use of Skeletal Muscle Relaxants in Geriatric Patients

Skeletal muscle relaxants, also called muscle relaxers, may be divided into two classes: antispasmodics and antispastics. Antispasmodics are agents that specifically treat muscle spasms. Muscle spasm occurs as a result of injury to muscles, tendons, or ligaments and is often synonymous with low back sprain or strain.10,11 Antispastics (sometimes referred to as spasmolytics) are agents that specifically treat muscle spasticity. Muscle spasticity is a condition in which the patient experiences continuous muscle spasms as a result of spinal motor neuron overactivity.

Tizanidine: An overlooked alternative muscle relaxant for older patients

Muscle relaxants have an association with mortality, hospitalizations, and emergency department visits in older patients. Determining a preferred option may be beneficial to help guide prescribing in this patient population. Tizanidine may be an effective and potentially safer choice for most indications.

3 Reasons NOT to Take Muscle Relaxers for Back Pain

Like most pain medications, muscle relaxers aren’t able to pinpoint their approach to the single muscle group affected. In fact, these medications are only effective at all thanks to their ability to sedate the body globally and numb you to pain. But this means that all muscles will become relaxed – including the ones that didn’t fire properly and caused the initial injury in the first place. As these improperly firing muscles become more and more relaxed, the root cause of the issue will only be aggravated and you won’t be able to consciously move in a way that would promote healing and strengthening of weak areas.

5 Muscle Relaxing Medications Commonly Used for Pain Management

Muscle relaxants are a group of medications that have an overall sedative effect, musculoskeletal relaxant properties, and central nervous system depressant. They are prescribed to reduce muscle spasms, which can cause severe pain and limit mobility.

Research isn’t very robust on the use of muscle relaxants for back pain. The use of these drugs may also be considered controversial by some physicians.
