What You'll Learn
Muscle relaxers are central nervous system depressants
Muscle relaxers are prescription medications that can help treat several symptoms, such as muscle spasms, spasticity, and musculoskeletal pain. They are central nervous system depressants that cause a sedative effect, preventing nerves from sending pain signals to the brain. This is why muscle relaxers are often used to promote relaxation, relieve anxiety, and induce sleep.
Most muscle relaxers act as central nervous system depressants, slowing down brain activity. They interfere with muscle reflexes and decrease skeletal muscle tone. The most commonly prescribed muscle relaxers are carisoprodol (Soma) and cyclobenzaprine (Flexeril). Cyclobenzaprine is used to relax certain muscles in the body and relieve pain, stiffness, and discomfort caused by strains, sprains, or injuries. It acts on the central nervous system (CNS) to produce its muscle relaxant effects.
The side effects of muscle relaxers are usually well-tolerated when used short-term and at recommended doses. However, the use of muscle relaxers in older adults carries a higher risk of side effects, such as sedation, confusion, urinary retention, or memory problems. This is because the body's ability to process and clear medications declines with age, and older adults are more likely to have impaired liver or kidney function, which can enhance the sedating side effects.
Combining muscle relaxers with alcohol or cannabis increases the risk of sedation and impairment. This is because alcohol also depresses the central nervous system, so when consumed with muscle relaxers, the side effects are exacerbated and can be very dangerous. For example, combining muscle relaxers with alcohol can lead to extreme dizziness, drowsiness, blurred vision, low blood pressure, and memory problems.
Prolonged use of muscle relaxers can lead to increased tolerance and physical dependence, especially with Soma. Muscle relaxers have the potential to be abused because of their calming, sedating, or even euphoric effects. They are intended as a short-term treatment, usually not prescribed for more than 2-3 weeks.

They can be abused and cause addiction
Muscle relaxers are prescription medications that can help treat symptoms like muscle spasms, spasticity, and musculoskeletal pain. They are designed to treat pain and are prescribed at a doctor's discretion for specific conditions. They work in different ways to affect muscle function. Most muscle relaxers act as central nervous system depressants and cause a sedative effect, or prevent nerves from sending pain signals to the brain.
While muscle relaxers serve a valuable medical purpose, they can be abused and cause addiction. According to the National Library of Medicine, skeletal muscle relaxants can be the primary drug a person abuses, but they are often used alongside other central nervous system depressants, such as narcotics or alcohol. This is because these substances enhance each other, producing a more powerful effect. The Mental Health Services Administration estimated that in 2018, 1.7 million Americans aged between 12 and 25 had misused muscle relaxers.
Muscle relaxers have calming, sedating, or even euphoric effects, and this can lead to physical and psychological addiction or dependence. Using the medication for purposes other than the intended use or taking it in excessive amounts can lead to addiction. Muscle relaxers that are commonly associated with the risk of abuse and/or dependence include Soma, which has been linked to a high number of emergency department visits and dozens of deaths. It is the only muscle relaxant classified as a controlled substance. Other muscle relaxers with a high risk of abuse include Diazepam (Valium), Tizanidine (Zanaflex), and Baclofen (Lioresal).
The risk of developing an addiction to muscle relaxers increases if a person has a history of certain forms of mental illness or behavioural conditions such as substance use disorder. The use of muscle relaxers with alcohol or cannabis increases the risk of sedation and impairment, and can cause slurred speech, confusion, nausea, and memory lapses. They can also lead to slowed breathing or, in severe cases, respiratory depression, as well as a slowed heart rate. Alcohol and muscle relaxers together have powerful sedative effects and can cause extreme drowsiness, making driving particularly dangerous.
Withdrawal symptoms from muscle relaxers can be quite severe, so quitting 'cold turkey' is not recommended. This is especially true if a person is detoxing from other substances used alongside muscle relaxers, as they may be at risk of further symptoms such as seizures.

They can cause liver damage
Muscle relaxers are prescription medications that can help treat symptoms like muscle spasms, spasticity, and musculoskeletal pain. They are central nervous system depressants and cause a sedative effect, preventing nerves from sending pain signals to the brain. While they can be effective in managing pain, muscle relaxers also carry certain risks and side effects, one of which is liver damage.
Some muscle relaxers have the potential to cause liver damage, and the extent of this damage can vary depending on the specific medication. Liver injury associated with muscle relaxers can range from elevated liver enzyme levels to severe liver toxicity. It is important to note that in most cases, liver function returns to normal once the medication is discontinued. However, it is crucial to be aware of this potential side effect and monitor liver function during treatment.
Older adults are at a higher risk of experiencing side effects from muscle relaxers, including liver-related issues. This is because the body's ability to process and clear medications declines with age, and older individuals are more likely to have impaired liver function. As a result, the sedating side effects of muscle relaxers can be enhanced in this population. Therefore, it is advisable to discuss the risks and benefits with a healthcare professional before taking muscle relaxers, especially for older adults.
Additionally, combining muscle relaxers with certain medications or substances can increase the risk of side effects. For example, using muscle relaxers with alcohol or other central nervous system depressants can lead to increased sedation and impairment. It is important to consult a healthcare provider before taking muscle relaxers concurrently with other medications to avoid potential drug interactions and adverse effects.
While muscle relaxers can be beneficial in managing muscle pain and spasms, it is important to be aware of their potential side effects, including liver damage. Prolonged use or abuse of muscle relaxers can lead to physical dependence and tolerance, requiring higher doses to achieve the same effect. Therefore, muscle relaxers are typically recommended for short-term use, usually not exceeding 2-3 weeks. It is crucial to follow the instructions provided by a healthcare professional and be vigilant for any signs or symptoms that may indicate liver injury or other adverse effects, such as drowsiness, dizziness, fatigue, and seizures.

They can cause drowsiness and dizziness
Muscle relaxers are prescription medications that can help treat symptoms like muscle spasms, spasticity, and musculoskeletal pain. They are central nervous system depressants and cause a sedative effect, preventing nerves from sending pain signals to the brain. While muscle relaxers are effective in treating spasticity, high doses can lead to unwanted side effects.
One common side effect of muscle relaxers is drowsiness. This can cause individuals to feel more tired, lack energy, or have difficulty concentrating. Drowsiness can impact daily activities such as driving, operating machinery, or performing tasks that require alertness and focus. It is important for individuals taking muscle relaxers to be aware of how they react to the medication before engaging in activities that require full alertness.
Another side effect of muscle relaxers is dizziness. Dizziness can vary in intensity and may be accompanied by a lack of energy and difficulty in concentration. In some cases, dizziness may be mild and manageable, while in other cases, it can be more severe and impact daily functioning. It is important for individuals taking muscle relaxers to monitor their symptoms and consult a healthcare professional if dizziness becomes bothersome or interferes with their daily activities.
The combination of muscle relaxers with other substances, such as alcohol or certain medications, can increase the risk of sedation and impairment. For example, using muscle relaxers with alcohol or cannabis can enhance their sedative effects, leading to greater drowsiness and dizziness. Additionally, older adults taking muscle relaxers may experience more significant side effects, including sedation, confusion, urinary retention, or memory problems. This is due to the body's decreased ability to process and clear medications, as well as potential liver or kidney function impairment, which can enhance the sedating effects.
It is important for individuals taking muscle relaxers to be aware of the potential side effects, including drowsiness and dizziness, and to follow the instructions provided by their healthcare provider or pharmacist. Adjustments to dosage or treatment options may be made if side effects become bothersome or interfere with daily life.
