Naproxen With Cyclobenzaprine or Oxycodone Acetaminophen for Acute Low-Back Pain

Naproxen With Cyclobenzaprine or Oxycodone Acetaminophen for Acute Low-Back Pain

Dogs can take muscle relaxers such as Flexeril for pain relief. Veterinarians suggest short-term treatments with Flexeril for dogs and cats with acute muscle spasms. However, the dosage strength differs for humans and dogs, and dogs are at risk for addiction. Cyclobenzaprine (Flexeril) is structurally similar to TCAs and, as such, demonstrates significant anticholinergic side effects. Additionally, if musculoskeletal doses are exceeded, cyclobenzaprine exhibits a side-effect profile similar to that of TCAs, including lethargy and agitation, although it usually does not appear to produce significant dysrhythmias beyond sinus tachycardia. It is generally used for musculoskeletal conditions, including fibromyalgia and low back pain.

In the case of an extended-release formulation, the effects last for up to 24 hours. It is not controlled under the Controlled Substances Act (CSA), either. However, since Flexeril has properties that suppress pain, people may overuse it to amplify those feelings.

Beginning in April 2012, a total of 2588 patients were approached for enrollment. Of the 323 deemed eligible for participation, 107 were randomized to receive placebo and 108 each to cyclobenzaprine and to oxycodone/acetaminophen. Flexeril is a strong muscle relaxant used with rest and physical therapy to treat muscle spasms. However, it is only for short-term relief from acute muscle pain and other skeletal conditions.

It relaxes only the muscles and not the actual causative nerves behind the pain. For best results, doctors recommend combining the use of Flexeril with rest and physical therapy. Baclofen is one of the most powerful centrally acting muscle relaxants. It is usually indicated in patients with spasticity such as cerebral palsy or multiple sclerosis. In children 2 to 7 years old, the dose is 10 to 15 mg/day, divided in two to three doses. The dose can be escalated every 3 days by 5 mg to a maximum dose of 40 mg/day.

Talk to your doctor or pharmacist if you have any questions or concerns. Muscle relaxants are frequently used as an adjunct to other medications (mostly NSAIDs) in patients with myofascial pain. Elderly patients seem to tolerate cyclobenzaprine less and may develop hallucinations as well as significant anticholinergic side effects, such as sedation. The use of significant lower dosing schedules in elderly patients may be prudent. Cyclobenzaprine is structurally similar to tricyclic antidepressants (TCAs) and has similar anticholinergic side effects such as sedation, dizziness, tachycardia, arrhythmias and may worsen heart failure, cardiac conduction abnormalities, and benign prostatic hyperplasia [29r]. Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction.

Ask your healthcare professional how you should dispose of any medicine you do not use. The dose of this medicine will be different for different patients. The following information includes only the average doses of this medicine.

  • More than 75% of participants randomized to receive naproxen used it daily and nearly two-thirds used it twice daily (Table 3).
  • Baclofen is one of the most powerful centrally acting muscle relaxants.
  • Do not flush medications down the toilet or pour them into a drain unless instructed to do so.
  • For non-prescription products, read the label or package ingredients carefully.

At 1-week follow-up, regardless of study group, more than 50% of patients still required medication for LBP, and as shown in Table 2, many patients reported moderate or severe, and frequent pain. Despite these generally poor outcomes, more than two-thirds of patients reported that they would want to receive the same medications during a subsequent ED visit for acute LBP. The drug Cyclobenzaprine, sold under the brand Flexeril, is structurally very similar to a class of Antidepressants called Tricyclic Antidepressants. Flexeril is commonly prescribed to induce pain relief from muscle spasms and improve motor skills, sleep, and energy levels by generating pain relief. These feelings may potentially be a cause for misuse of Flexeril and lead to addictive effects. Although all skeletal muscle relaxants should be used with caution in older patients, diazepam especially should be avoided in older patients or in patients with significant cognitive or hepatic impairment.

However, we chose this study design because it more closely reflects the reality of clinical practice. Quiz Ref IDPatients were excluded for radicular pain, which we defined as pain radiating below the gluteal folds, direct trauma to the back within the previous month, pain duration for more than 2 weeks, or recent history of greater than 1 LBP episode per month. We also excluded patients who were pregnant or lactating, unavailable for follow-up, with allergy or contraindication to the investigational medications, or had chronic opioid use currently or in the past.

It is important to note that only 63% of the patients took the naproxen as prescribed. Additionally, only 62% of the patients took the study medication at least once per day, with 8% of the patients taking the medication only one time and 16% of the patients never taking the medication at all. Considering that 24% of the patients took the medication once or never, this may have affected the internal validity by blunting the effect difference between study groups. Therefore, it is possible that, if the medications were taken as prescribed, a difference may have been noted that was not identified in the study. However, this also increases the external validity, as patients are not always compliant with medications, and although having frequent reminders and phone calls to take medications may increase patient compliance, this approach is unrealistic in common practice.
