Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They are central nervous system depressants that cause a sedative effect, preventing nerves from sending pain signals to the brain. While muscle relaxers can be effective in treating muscle spasms, they also come with a range of side effects, including drowsiness, dizziness, fatigue, blurred vision, and fainting. Some muscle relaxers have the potential to be abused due to their calming and euphoric effects, leading to physical and psychological addiction. Additionally, there are concerns about their impact on respiration and circulation. This raises the question: can muscle relaxers cause coughing, and what are the implications for respiratory health?

What You'll Learn
Muscle relaxers can cause drowsiness, dizziness, and fatigue
Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They can be taken in different forms, such as tablets, capsules, solutions, or injections. While muscle relaxers can be effective in treating muscle-related issues, they can also cause various side effects, including drowsiness, dizziness, and fatigue.
Drowsiness is a common side effect of muscle relaxers because they have a sedative effect on the central nervous system, which includes the brain and spinal cord. The severity of drowsiness can depend on the specific medication and the dosage prescribed. It is important to be cautious when operating heavy machinery or making important decisions while taking these medications. Additionally, combining muscle relaxers with other medications that cause drowsiness can lead to increased side effects.
Dizziness is another frequently reported side effect of muscle relaxers. This dizziness can be attributed to the impact of the medication on the central nervous system, particularly the brain and spinal cord. In some cases, dizziness may be accompanied by other symptoms, such as confusion or trouble staying awake. It is advisable to consult a healthcare professional if dizziness becomes a concern.
Fatigue is also a potential side effect of muscle relaxers. As muscle relaxers slow down the central nervous system, individuals may experience increased tiredness, lack of energy, or difficulty concentrating. If fatigue interferes with daily activities, it is recommended to discuss this with a healthcare provider to determine the appropriate course of action.
While muscle relaxers can cause these side effects, the impact on individuals may vary. The right dosage can be determined with the help of a healthcare team to minimize these side effects. Additionally, older adults may be at a higher risk for muscle relaxer side effects, and it is important to consider potential drug interactions when taking multiple medications or supplements.

They can also lead to liver damage
While muscle relaxers can be effective in treating spasticity and muscle spasms, they are associated with a range of side effects, including drowsiness, dizziness, fatigue, and blurred vision. The use of muscle relaxers, especially in older adults, carries a higher risk of sedation, confusion, urinary retention, and memory problems. Furthermore, some muscle relaxers can cause liver damage, ranging from increased liver enzyme levels to severe liver toxicity.
The severity of side effects associated with muscle relaxers can vary depending on the specific medication and the dosage. It is important to note that older adults are more likely to experience impaired liver function, which can enhance the sedating effects of these medications. Additionally, older adults often take multiple medications and supplements, increasing the risk of drug interactions that intensify side effects. Therefore, it is advisable to consult a doctor and consider non-drug therapies before prescribing muscle relaxers to older adults.
Certain muscle relaxers, such as Tizanidine (Zanaflex®) and Dantrolene (Dantrium®), have been associated with liver damage. Liver injury can range from mild increases in liver enzyme levels to severe liver toxicity. In most cases, liver function returns to normal once the medication is discontinued. However, it is crucial to carefully review and manage medications that may contribute to liver damage.
While muscle relaxers can provide relief from muscle spasms and spasticity, it is important to be aware of their potential side effects, including liver damage. Patients taking muscle relaxers should be monitored for any signs or symptoms indicative of liver injury, and healthcare providers should carefully evaluate the benefits and risks before prescribing these medications, especially to individuals with pre-existing liver conditions or those taking multiple medications.
To mitigate the risk of liver damage, it is essential to follow the instructions provided by healthcare providers and pharmacists when taking muscle relaxers. Patients should also be vigilant about reporting any unusual symptoms or side effects, especially those indicative of liver dysfunction, such as jaundice, abdominal pain, nausea, or changes in bowel movements. By closely monitoring for these signs and adjusting the treatment plan as necessary, healthcare providers can help ensure the safe and effective use of muscle relaxers while minimizing the risk of liver-related complications.

Muscle relaxers can be abused due to calming, sedating, or euphoric effects
Muscle relaxers are prescription medications that can help treat muscle-related symptoms like spasticity and spasms. They are usually intended for short-term relief. Muscle relaxers are generally pills or tablets that, when taken as prescribed, can be very effective in managing muscle spasms or pain.
Muscle relaxers can be abused due to their calming, sedating, or euphoric effects. Using the medication for purposes other than the intended use or taking it in excessive amounts can lead to both physical and psychological addiction or dependence. Muscle relaxers are often misused, and any use outside of a legitimate and necessary prescription is considered abuse. The misuse of muscle relaxers can lead to an increased risk of overdose, which can result in changes in consciousness, hallucinations, respiratory depression, and cardiac arrest.
The calming effects of muscle relaxers are due to their impact on the central nervous system. They slow down the central nervous system or interfere with nerve transmission, which can signal muscles to spasm. Most skeletal muscle relaxers prevent nerves from sending pain signals to the brain, which can lead to muscle spasms and/or have a sedative effect to minimize muscle spasms.
The sedative effects of muscle relaxers can be severe enough to impair the mental and physical abilities of some people, especially older adults or those taking other sedating medications. Most people will experience mild to moderate sedation, which can impact daily activities like driving. Combining muscle relaxers with alcohol or cannabis also increases the risk of sedation and impairment.
The euphoric effects of muscle relaxers can cause a kind of relaxed "high." When used at regular doses, the body can develop a tolerance to certain muscle relaxers, and a higher dose will eventually be needed to achieve the original effect. Muscle relaxers that are commonly associated with the risk of abuse and/or dependence include Soma and Diazepam.

They may cause blurred vision and fainting
Muscle relaxers are prescription medications that can help treat symptoms like spasticity and muscle spasms. They are central nervous system depressants and cause a sedative effect, preventing nerves from sending pain signals to the brain. While muscle relaxers can be effective in treating muscle spasms, they can also lead to various side effects, including drowsiness, dizziness, fatigue, and blurred vision.
One of the most common side effects of muscle relaxers is drowsiness. This occurs because most muscle relaxers have a sedative effect on the central nervous system, which includes the brain and spinal cord. The severity of drowsiness can vary depending on the specific muscle relaxer and the dosage. It is important to note that muscle relaxers may also cause blurred vision and fainting, which are considered more serious side effects.
The risk of experiencing side effects from muscle relaxers is typically higher in older adults due to age-related changes in the body's ability to process and clear medications. Older adults are also more likely to have impaired liver or kidney function, which can enhance the sedating effects of muscle relaxers. Additionally, polypharmacy, or the use of multiple medications, in older adults may increase the risk of drug interactions that intensify the side effects of muscle relaxers.
Certain muscle relaxers, such as carisoprodol and diazepam, are controlled substances due to their potential for addiction and dependence. It is important to follow the prescribed dosage and not exceed it, as taking excessive amounts can lead to physical and psychological addiction or dependence. If you feel dependent on these medications or find that the prescribed dosage is no longer effective, consult your healthcare provider.
While muscle relaxers can provide relief from muscle spasms, it is crucial to be aware of their potential side effects. If you experience bothersome side effects, such as blurred vision or fainting, it is important to discuss them with your healthcare provider. They may adjust the dosage or recommend alternative treatments to manage your muscle spasms effectively while minimizing side effects.

Muscle relaxers can affect breathing and circulation
Additionally, muscle relaxers can affect circulation by inhibiting parasympathetic and sympathetic ganglia, anticholinesterase activity, and histamine release. While animal studies have shown that muscle relaxants generally depress respiration and have no effect on circulation, there are exceptions and variations when applied to humans. Individual responses, the specific muscle affected, the drug used, and the dosage can all influence the impact on circulation.
The muscle relaxant baclofen, for example, has been shown to suppress coughs in cats without affecting their breathing patterns. However, in humans, baclofen has been associated with the GABA receptor, which can inhibit various responses in the airways, including smooth muscle contraction, potentially impacting breathing. While baclofen has shown promising results in treating cough hypersensitivity syndrome (CHS) and refractory coughs, it is not known to directly cause coughing.
Furthermore, muscle relaxers can cause other side effects such as drowsiness, dizziness, fatigue, fainting, blurred vision, and liver damage. Some muscle relaxers, such as carisoprodol and diazepam, are controlled substances due to their potential for addiction and withdrawal symptoms. It is important to follow the instructions provided by healthcare providers and pharmacists when taking muscle relaxers and to be cautious when operating heavy machinery or making important decisions while under the influence of these medications.
