Can carisoprodol be taken with trazodone? (5+ side effects)
In this article, we will discuss whether carisoprodol can be taken with trazodone or not. Furthermore, we’ll explore the potential interactions between carisoprodol and trazodone, what research suggests on this, the risks and side effects associated with their concurrent use and precautionary measures to ensure safety when combining them.
Can carisoprodol be taken with trazodone?
Carisoprodol may or may not be taken with trazodone. Both of these medications have depressive effects on the central nervous system and their concurrent use might exacerbate the risk of additive side effects. (1)
Trazodone, an antidepressant, is FDA-approved for the treatment of major depressive disorders and it may also be used off-label to promote sleep quality in insomniac patients. It is classified as a serotonin modulator that exerts its effects by increasing the levels of serotonin in the brain. This neurotransmitter is responsible for mood-uplifting and boosting motivation in a person, thereby reducing the feeling of sadness and anxiety. (3)
Carisoprodol, on the other hand, is a widely used muscle relaxant. It is typically prescribed for short-term use in the treatment of muscle pain and discomfort associated with acute muscular-skeletal conditions. It is believed to work by affecting interneuronal activities in the brain and spinal cord. (1)
If you’re considering using these two medications together, it’s best to consult with your healthcare provider before starting the medication. They may assess your health condition and identify the benefits-to-risk profile ratio of trazodone and carisoprodol.
What are the possible interactions between carisoprodol and trazodone?
The combination of carisoprodol ( a muscle relaxant) and trazodone (an antidepressant with a sedative effect) can individually cause depression in the central nervous system which slows down the body’s overall physiological functions. (1,3)
Trazodone is considered to have sedative effects as it is also used in the treatment of insomnia along with depression and carisoprodol although being a muscle relaxant exerts sedative properties to help relax the tension built-in skeletal muscles for quick relief of pain. Combining these two medications can intensify the risk of excessive drowsiness and fatigue due to depressed CNS. (3)
The increased sedative and depressing effects on the CNS may also influence a person’s cognitive functions and cause impairment in motor coordination which may increase the risk of accidents and falls and impact daily activities that require focus and concentration. Both of these medications at higher doses are also associated with respiratory depression which leads to difficulties in breathing. (2)
It’s important to recognize that individual’s responses to medications can vary as everyone is different in terms of their brain chemistry and how they process and respond to certain medications. So some people may be more tolerant of the use of this combination while others may experience side effects.
What does research suggest?
There is not much clinical research reported related to the concurrent use of carisoprodol along with trazodone. However, healthcare professionals suggested that it is not approved by the FDA to take these two drugs together due to the increased risk of addiction and dependence associated with carisoprodol and their depressive effects on the central nervous system. (1)
A patient suffering from depression and anxiety is most likely to experience muscle stiffness as a side effect of antidepressants like trazodone. Muscle relaxers having a high safety profile with fewer interactions and synergistic effects are more commonly recommended to treat muscle spasms in depressive patients rather than giving skeletal muscle relaxants with high effects of sedation and CNS depression. Also, the dose and timing between the medications must be kept in consideration for minimal interaction. (1,3)
What are the side effects of using carisoprodol and trazodone together?
Combining carisoprodol and trazodone may lead to an increased risk of side effects due to the potential additive effects of these medications. Some common side effects associated with the use of this combination include: (1,4)
The combined use of trazodone and carisoprodol may result in increased sedation. A person can feel drowsy and overly sleepy at unusual times.
Impaired cognitive function:
Both medications can influence cognitive functions, impacting the memory and concentration of a person and combining them might exacerbate these effects.
Dizziness and lightheadedness:
Dizziness and lightheadedness are common side effects associated with trazodone and carisoprodol and taking them together may increase the extent and severity of these effects.
The concurrent use of trazodone and carisoprodol may interfere with a person’s motor coordination and higher amounts might cause impairment, affecting activities that require physical coordination and alertness such as driving or operating heavy machinery.
Both drugs can have respiratory depressive effects individually and combining them may exacerbate the risk and severity of respiratory depression.
Nausea or upset stomach:
Both medications can have mild to moderate gastrointestinal side effects including nausea, vomiting, diarrhoea, abdominal pain etc.
Hypotension (low blood pressure):
Trazodone and carisoprodol may both cause a drop in blood pressure due to inhibitory effects on the nervous system and combining them may increase the risk of hypotension even more, especially when standing up quickly, this condition is also referred to as orthostatic hypotension.
Increase the risk of overdose:
Taking higher than prescribed doses of either trazodone or carisoprodol or combining them with other substances that cause CNS depression may increase the risk of toxicity.
How to ensure the safe use of carisoprodol and trazodone?
Ensuring the safe and effective use of carisoprodol and trazodone requires medical supervision and guidance. Only use carisoprodol and trazodone with the approval of your healthcare provider. Stick to the recommended dosage regimen and appropriate timings of the medication. Do not change the dose on your own nor stop the use abruptly as you may suffer withdrawal side effects as a consequence. These medications are only tapered off gradually over time. (4)
Be vigilant and keep an eye on how your body is responding to these medications. If you sense any discomfort or unusual symptoms inform your doctor promptly. Tell your doctor about your medical industry including all pre-existing health conditions or allergies and give them the list of all the medications you might have been taking including prescription and OTC medications and herbal supplements as well. (1)
With the above-mentioned data, your doctor may be able to assess your specific situation and tailor a treatment plan accordingly to rule out the risk of ADRs and harmful interactions or allergic reactions. Try to limit the overconsumption of alcohol and cease the use of any recreational drugs that further depress the nervous system and exacerbate side effects.
If you’re taking other medications that affect serotonin levels like Citalopram, Sertraline etc, be aware of the symptoms of serotonin syndrome which is a rare but life-threatening condition, caused by the excessive accumulation of serotonin. If you’re pregnant, planning to conceive or breastfeeding, please consult your doctor before starting any antidepressants to ensure the safety of your fetus and avoid complications. (5)
As a pharmacist, in my opinion, it’s better to choose the safer muscle relaxant in case you need it when experiencing any muscular illness while suffering from depression because trazodone is already a CNS depressant with sedative effects and using carisoprodol along with it will not only cure muscular pain but also exacerbate the sedative side effects.
Ask your healthcare provider to prescribe you a non-sedative muscle relaxant or topical ointment to reduce the risk of interactions and get the intended therapeutic effects from both. Also, try out muscle relaxing exercises to release your muscle tension and stiffness rather than being solely dependent on medications.
