Muscle pain and muscle spasms: what this article covers
When muscle pain is linked to a strain, sprain, back injury, or painful spasm, a clinician may consider a muscle relaxant or an anti-inflammatory pain reliever. These medicines are usually used short term and only when appropriate for the person’s situation.
This overview focuses on the medicines mentioned in the original content and the main safety points to verify with a healthcare professional or official patient leaflet.
Antispasmodic muscle relaxants
Antispasmodic muscle relaxants may be prescribed for acute and painful musculoskeletal pain or injury. For example, if someone has pulled their back and has reduced mobility with severe spasms, a muscle relaxant may be considered.
| Medicine | Common use mentioned | Noted side effects |
|---|---|---|
| Cyclobenzaprine (Flexeril, Amrix) | Short-term treatment of muscle spasms and cramps, sprains, and strains | Drowsiness, dry mouth, dizziness, fatigue |
| Methocarbamol (Robaxin) | Severe muscle spasms, back pain, and sometimes tetanus spasms | Drowsiness, dizziness, blurred vision, injection site reactions with intravenous use |
| Metaxalone (Skelaxin) | Muscle and bone pain with central nervous system effects | Drowsiness, dizziness, irritability, nausea |
| Carisoprodol (Soma) | Acute musculoskeletal pain | Drowsiness, dizziness, headache; linked to addiction risk |
| Chlorzoxazone (Lorzone) | Pain and spasms associated with muscle and bone conditions | Drowsiness, dizziness, lightheadedness, malaise; rare gastrointestinal bleeding |
| Orphenadrine (Norflex) | Injury-related pain and spasms; also used for tremors in Parkinson’s disease | Dry mouth, palpitations, blurred vision, weakness, nausea, headache, dizziness, constipation, drowsiness |
Cyclobenzaprine (Flexeril, Amrix)
Cyclobenzaprine is described as a popular and relatively inexpensive general-purpose muscle relaxant. It is often used short term for muscle spasms and cramps, including sprains and strains. Common side effects include drowsiness, dry mouth, dizziness, and fatigue.
Methocarbamol (Robaxin)
Methocarbamol is commonly used for severe muscle spasms and back pain, and it is sometimes used for tetanus spasms. The original content notes that it is generally less sedating than many other muscle relaxants, although drowsiness, dizziness, blurred vision, and injection site reactions can occur.
Metaxalone (Skelaxin)
Metaxalone is described as slightly more expensive than some alternatives, but with a relatively low rate of side effects. It can still cause drowsiness, dizziness, irritability, and nausea.
Carisoprodol (Soma)
Carisoprodol is used for pain associated with acute musculoskeletal disorders. The original content notes that it should be used with caution because it has been linked to addiction. Common side effects include drowsiness, dizziness, and headache.
Chlorzoxazone (Lorzone)
Chlorzoxazone is another muscle relaxant used for pain and spasms related to muscle and bone conditions. It is described as fairly well tolerated, though drowsiness, dizziness, lightheadedness, and malaise may occur. Rare gastrointestinal bleeding is also mentioned in the source content.
Orphenadrine (Norflex)
Orphenadrine is used for injury-related pain and spasms and is also noted for tremor relief in Parkinson’s disease. Side effects listed in the original content include dry mouth, palpitations, blurred vision, weakness, nausea, headache, dizziness, constipation, and drowsiness, especially at higher doses.
NSAIDs and muscle pain
Nonsteroidal anti-inflammatory drugs, or NSAIDs, reduce prostaglandins in the body. Prostaglandins are hormone-like substances that can irritate nerve endings and contribute to pain. By lowering prostaglandins, NSAIDs can reduce the sensation of pain.
NSAIDs are often used for pain that has an inflammatory component, but the best choice depends on the person’s age, medical history, and other medicines.
What is the safest over-the-counter pain reliever for an aging parent?
For most older adults, the safest over-the-counter oral pain reliever for daily or frequent use is acetaminophen, as long as the total daily dose does not exceed 3000 mg. This should still be confirmed with a doctor or pharmacist, especially if the person has liver disease or takes other medicines that may contain acetaminophen.
What to check before using any pain reliever
- Whether the pain is from a strain, sprain, spasm, or another cause
- Whether the medicine may cause drowsiness or affect driving
- Whether the person takes other medicines that could interact
- Whether there is a history of stomach bleeding, liver disease, kidney disease, or addiction concerns
- Whether the official leaflet gives different instructions from what is listed here
Safety reminder
Muscle relaxants and pain relievers can cause side effects and may not be suitable for everyone. If pain is severe, persistent, worsening, or linked to numbness, weakness, fever, or injury, seek medical advice promptly. Always follow the directions on the prescription label or official leaflet.
FAQs
▸ Are muscle relaxants the same as painkillers?
No. Muscle relaxants are used to help with spasms, while painkillers reduce pain. Some people may need one or the other, and sometimes both are considered by a clinician.
▸ Why do many muscle relaxants cause drowsiness?
Many of these medicines act on the central nervous system, which can lead to sleepiness, dizziness, or slowed reactions.
▸ Is acetaminophen always the safest option for older adults?
It is often considered the safest oral option for frequent use in older adults, but it is not right for everyone. The total daily dose and other health conditions still matter.
▸ Can NSAIDs help with muscle pain?
Yes, NSAIDs can help reduce pain, especially when inflammation is part of the problem. A doctor or pharmacist can help decide whether they are appropriate.
▸ Why is carisoprodol mentioned with caution?
The original content notes that carisoprodol has been linked to addiction, so it should be used carefully and only as directed by a clinician.
Final takeaway
For strong muscle pain, the best medicine depends on the cause of the pain, the presence of spasms, and the person’s overall health. The medicines listed here can help in some situations, but they also carry side effects that should be reviewed with a healthcare professional.
