Muscle relaxers are prescription medications that can help treat muscle spasms and acute muscle pain. They work by inhibiting nerve signals in the brain and spinal cord, ultimately reducing muscle hyperactivity. While muscle relaxers can be effective in relieving pain, they can also cause several side effects, including drowsiness, gait disturbances, nausea, and blurred vision. Due to their impact on the central nervous system, muscle relaxers can also lead to addiction and withdrawal symptoms if misused or abruptly discontinued. Sporadic reports suggest that certain muscle relaxers, such as cyclobenzaprine, may cause mood changes, including confusion and hallucinations, in susceptible individuals. Therefore, it is crucial to follow the prescribed dosage and consult a healthcare provider if any adverse effects occur.

What You'll Learn
Muscle relaxers are central nervous system depressants
Muscle relaxers are prescription medications that help treat muscle spasms, spasticity, and musculoskeletal pain. They work by acting on the central nervous system, causing a sedative effect and preventing nerves from sending pain signals to the brain. Most muscle relaxers are central nervous system depressants, which means they slow down brain activity to promote relaxation, relieve anxiety, and induce sleep.
Central nervous system depressants, or CNS depressants, are medications that slow brain activity. They are commonly used to promote relaxation, relieve anxiety, and induce sleep. CNS depressants are also used for sedation before and during invasive medical procedures. While these medications can be beneficial in certain situations, they can also have negative side effects and the potential for misuse and addiction.
Muscle relaxers are a type of CNS depressant that specifically targets muscle spasms and associated pain. They work by interfering with muscle reflexes and decreasing skeletal muscle tone, which helps to reduce involuntary contractions and relieve pain. The most commonly prescribed muscle relaxants in the United States include carisoprodol (Soma) and cyclobenzaprine (Flexeril).
While muscle relaxers can be effective in treating muscle pain and spasms, they can also cause side effects such as drowsiness, dizziness, blurred vision, and impaired coordination. One of the main risks associated with muscle relaxers is their potential for misuse and addiction. When combined with alcohol or other drugs, the side effects of muscle relaxers can be exacerbated, leading to dangerous symptoms such as extreme drowsiness, blurred vision, low blood pressure, memory problems, and liver damage.
Due to their depressant effects on the central nervous system, muscle relaxers can cause sedation and impair coordination and decision-making abilities. Therefore, it is important for individuals taking these medications to refrain from operating heavy machinery or driving until they know how the medication affects them. Additionally, muscle relaxers should not be combined with alcohol or other central nervous system depressants as it can lead to profound sedation and increased risk of overdose.

They can be addictive
Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They are typically obtained with a doctor's prescription and are meant to be taken for a short period. Muscle relaxants can be addictive for some people, and taking them without a prescription or in higher doses than prescribed can increase the risk of addiction.
The most commonly prescribed muscle relaxers are carisoprodol (Soma) and cyclobenzaprine (Flexeril). According to the Drug Enforcement Administration, Soma is one of the most commonly diverted drugs in the United States, with over 4.2 million prescriptions in 2017. Evidence also indicates the prevalent misuse of Flexeril, with over 12,000 emergency room visits associated with the drug in 2010.
Almost all cases of addiction and abuse are due to the drug carisoprodol (Soma), which is considered a Schedule IV controlled substance. This is because, when the drug breaks down in the body, it produces a substance called meprobamate that acts like a tranquilizer. People who become addicted to carisoprodol sometimes abuse the drug because they are no longer using it for medical reasons, and they crave it. Other kinds of muscle relaxants may be addictive too. Cyclobenzaprine (Flexeril) has also been linked to misuse and abuse. It shares a similar chemical structure with tricyclic antidepressants, which are often prescribed for patients with insomnia.
Regular use of muscle relaxers causes the brain to become accustomed to their effects, and stopping them suddenly can lead to withdrawal symptoms. The withdrawal symptoms vary depending on the specific drug and the duration of use. For example, Flexeril withdrawal may cause mild symptoms such as nausea, headache, drowsiness, malaise, and discomfort, while Soma withdrawal is usually more severe and can include hallucinations and seizures.
It is important to follow the prescribed dosage and duration for muscle relaxers and not combine them with alcohol or other sedating medications as this can lead to dangerous side effects and increase the risk of addiction. If you feel that you are dependent on muscle relaxers or experiencing withdrawal symptoms, consult your healthcare provider for guidance on tapering the dosage gradually and safely.

They can cause drowsiness
Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They are typically obtained with a doctor's prescription. However, they can also be addictive and cause drowsiness.
Muscle relaxers act as central nervous system depressants, causing a sedative effect or preventing nerves from sending pain signals to the brain. This mechanism of action can lead to drowsiness as a side effect. Drowsiness is a common condition and can be especially noticeable if the muscle relaxers are taken at night to aid sleep. The sedative effect of muscle relaxants can help treat disturbed sleep caused by back pain.
The specific type of muscle relaxer and dosage can influence the likelihood and severity of drowsiness. For example, Flexeril (cyclobenzaprine) withdrawal can cause mild symptoms such as nausea, headache, drowsiness, malaise, and discomfort. Seniors may be more susceptible to confusion and anesthesia as side effects of Flexeril therapy. Similarly, the muscle relaxer Soma (carisoprodol) has been associated with more severe withdrawal symptoms, including hallucinations and seizures.
Combining muscle relaxers with alcohol or other sedating medications can be dangerous and may exacerbate the drowsiness effect. According to the National Highway Traffic Safety Administration, drowsiness, impaired coordination, and even coma are possible side effects of mixing muscle relaxers with alcohol. Therefore, it is recommended to refrain from driving or operating heavy machinery while taking muscle relaxants due to their impact on cognitive function and decision-making abilities.
In summary, muscle relaxers can cause drowsiness due to their depressant effects on the central nervous system. This side effect can be beneficial for treating sleep disturbances caused by pain but may also pose risks when combined with certain substances or activities requiring alertness. It is important to follow the instructions provided by healthcare professionals when taking muscle relaxers to ensure safe and effective use.

Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They are often prescribed for acute muscle pain, especially lower back pain, and muscle spasms. Acute musculoskeletal back pain can be effectively treated with a short course of muscle relaxants in the first 3 weeks. They are also used when back pain causes disturbed sleep due to their sedative effect.
Muscle relaxers can be addictive, so it is recommended to use them for the shortest time possible and keep them away from children and other adults. They depress the central nervous system, which can affect breathing, and an overdose can be fatal. Combining muscle relaxants with alcohol or other sedating medications is extremely dangerous and can lead to harmful effects.
Muscle relaxers can cause drowsiness, gait disturbances, and an increased risk of falls and injuries, especially in the elderly. Other common side effects include dry mouth, dizziness, fatigue, constipation, nausea, and vomiting. In some cases, muscle relaxants can lead to more serious side effects, such as liver damage, fainting, and blurred vision.
While muscle relaxers can be effective in relieving acute muscle pain, it is important to be cautious of their potential side effects and addictive nature. It is always advisable to consult with a healthcare provider to determine if muscle relaxers are suitable for your specific situation.
