Prescription Medications for Pain Control in Renal Colic

First-Line Treatment: NSAIDs

The European Urology Association recommends NSAIDs as the first-line treatment for renal colic due to their superior efficacy and safety profile compared to opioids 2
The British Medical Journal suggests that diclofenac 75 mg administered intramuscularly is specifically recommended as the initial treatment of choice 1
NSAIDs reduce the need for additional analgesia compared to opioids and have fewer side effects, according to the European Urology Association 2

The European Urology Association recommends that when NSAIDs are contraindicated or insufficient for pain control, opioids should be used as second-line therapy 2
If an opioid is required, agents other than pethidine are recommended, such as hydromorphone, pentazocine, or tramadol, according to the European Urology Association 2
For patients with renal impairment, fentanyl is preferred as it does not accumulate active metabolites in renal failure 4

The British Medical Journal recommends that if severe pain does not remit within one hour of initial treatment, the patient should be admitted to hospital 1
The European Urology Association strongly recommends urgent decompression of the system via percutaneous nephrostomy or ureteral stenting in cases of sepsis and/or anuria in an obstructed kidney 2
Medical expulsive therapy (alpha-blockers) may be beneficial for patients with stones >5 mm in the distal ureter, according to the European Urology Association 2

Complete or acceptable pain control should be maintained for at least six hours, according to Praxis Medical Insights 3
Patients should be followed up (via telephone call) one hour after initial assessment and administration of analgesia, as recommended by Praxis Medical Insights 3

Praxis Medical Insights recommends avoiding the use of standard opioid dosing protocols for patients with renal failure; always start with lower doses and titrate carefully 4
Never use morphine, codeine, or tramadol as first-line agents in patients with renal failure, according to Praxis Medical Insights 4
