Neck and back pain are very common and can be caused by many factors. In some cases, doctors will prescribe muscle relaxants to treat these conditions.
Stiffness and pain in the neck and back can cause insomnia and affect the quality of life of those suffering from it. In some cases, muscle relaxants can help relieve the pain.
Muscle relaxants work by reducing muscle tension through various mechanisms, such as acting on muscles, nerves, or the central nervous system, helping to improve neck and back pain.
Some of the best muscle relaxants for neck and back pain.
There are many types of muscle relaxants on the market, each with its own advantages and disadvantages. Doctors can choose the medication that best suits each individual patient:
- Methocarbamol muscle relaxant
Methocarbamol is generally a well-tolerated option for those experiencing new neck and back pain. The medication works by blocking nerve impulses (or pain sensations) from being sent to the brain, thus reducing pain. Methocarbamol is used in combination with rest and physical therapy to treat musculoskeletal pain or injury conditions.
Neck and back pain can be caused by many factors, and in some cases, muscle relaxants may be used.
Common side effects of methocarbamol may include:
- Headache, dizziness, drowsiness;
- Confusion, memory problems;
- Nausea, vomiting, abdominal pain;
- Blurred vision, double vision;
- Sleep problems (insomnia);
- Lack of coordination…
- Cyclobenzaprine muscle relaxant
Cyclobenzaprine has a similar mechanism of action to methocarbamol and is used in conjunction with rest and physical therapy to relieve muscle pain. Cyclobenzaprine is more likely to cause drowsiness, making daytime use a concern (it's best to consider a non-sedating formulation suitable for daytime use).
Cyclobenzaprine can also cause dry mouth (especially in older adults), headache, dizziness, constipation, etc.
- Carisoprodol muscle relaxant
Carisoprodol is used in combination with rest and physical therapy to provide temporary relief from muscle pain. However, it is classified as a potentially abusive medication. Patients with a history of substance abuse should not use this medication. When prescribed, it should only be used for a short period (2-3 weeks).
Carisoprodol can also cause drowsiness and dizziness, so it's not a good option for people over 65. Due to these potential side effects, carisoprodol should not be the preferred choice and may be replaced by better alternatives.
- Metaxalone muscle relaxant
Metaxalone works by slowing down activity in the nervous system to allow the body to relax; it is used in conjunction with rest, physical therapy, and other measures to relax muscles and reduce pain and discomfort from muscle strain, sprains, or other muscle injuries.
This is the muscle relaxant with the fewest reported side effects and less sedative effect. However, it is more effective for recurrent chronic lower back pain than for new pain episodes.
There are many types of muscle relaxants, and doctors can choose the one that best suits each individual patient.
2. Precautions when using muscle relaxants
Muscle relaxants can cause some side effects, so users should carefully read the instructions before use. If side effects occur, inform your doctor so that appropriate and timely action can be taken. Muscle relaxants often cause drowsiness, so patients may need to avoid activities that require alertness while using these medications.
Interactions with other medications and substances the patient is using also need to be considered, which is why muscle relaxants require a doctor's prescription after a thorough examination.
Common medications that may interact with muscle relaxants include:
- Medications with sedative (drowsy) effects: Many muscle relaxants have sedative effects, slowing down brain activity. For people taking medications that affect the brain (such as zolpidem, gabapentin, opioid painkillers, etc.), the risk of experiencing these side effects is higher and more severe.
- Antidepressants: Some muscle relaxants can also affect serotonin levels in the brain—a hormone that affects mood. If you are taking mood-regulating medication, muscle relaxants may cause serotonin levels to rise excessively. Some antidepressants can interact with muscle relaxants, such as amitriptyline, venlafaxine, sertraline, fluoxetine, etc.
- Anticholinergic drugs: Anticholinergic drugs are commonly used to treat a variety of conditions, from overactive bladder to digestive conditions and movement disorders such as Parkinson's disease. These drugs can cause difficulty urinating, constipation, or dry mouth… and if used with muscle relaxants, these side effects can be more severe.
Some anticholinergic drugs include: Diphenhydramine (for allergies), hyoscyamine (for stomach and intestinal disorders, irritable bowel syndrome), benztropine (for Parkinson's disease and drug-induced extrapyramidal symptoms), scopolamine (an antispasmodic used to relieve nausea, vomiting, and dizziness from motion sickness)...
