A shot in the arm for renal colic : diclofenac feels the best
Bottom line: IM diclofenac is more effective than IV morphine or IV paracetamol at providing short-term pain relief (50 percent reduction in pain within 30 minutes of administration) in patients with symptoms of renal colic. Both diclofenac and paracetamol are associated with fewer adverse events than morphine. However, IM diclofenac is not available in the United States and it is not known if other IM NSAIDs would have the same effect.Review and summary of Pathan SA, Mitra B, Straney LD, et al.
