Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-70 who present to the emergency department with acute radicular low back pain lasting less than two weeks.

Probably not a fit

Patients with chronic back pain or those who have experienced significant trauma to the back in the past month may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study is a randomized, double-blind, placebo-controlled trial that aims to evaluate the effectiveness of dexamethasone in addition to ibuprofen for patients experiencing acute radicular low back pain. Patients will be enrolled during an emergency department visit and will receive either dexamethasone or a placebo for two days, along with a seven-day supply of ibuprofen and educational support on managing low back pain. Follow-up assessments will occur via telephone at two and seven days post-treatment to monitor outcomes.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from acute radicular low back pain.

How similar studies have gone: Previous studies have shown promising results for the use of corticosteroids in managing acute pain, suggesting that this approach may be beneficial.

Inclusion Criteria:

* Present to ED primarily for management of acute radicular LBP, defined as pain or paresthesia originating from the lower back and radiating to the buttock and or leg in a radicular pattern. Some patients may not have prominent LBP but a radicular symptom--we will include these patients as well.
* Patient is to be discharged home.
* Age 18-70 Enrollment will be limited to adults \<70 years because of the increased risk of adverse medication effects in older adults.
* Pain duration \<2 week
* Prior to the acute attack of radicular LBP, back pain cannot occur more frequently than half of the days in the last 3 months. Patients with more frequent back pain/sciatica are at increased risk of poor pain and functional outcomes.10
* Non-traumatic cause of pain: no substantial and direct trauma to the back within the previous month
* Functionally impairing radicular LBP: A baseline score of \> 5 on the Roland-Morris Disability Questionnaire

Exclusion Criteria:
