How effective are corticosteroid injections for treating carpal tunnel?

Donna Hill Howes, RN
Family Practitioner

Research shows that corticosteroid injections provide short-term relief of carpal tunnel syndrome. Some experts recommend trying 2 or 3 injections before considering carpal tunnel release surgery, but people should not have more than 3 or 4 injections. About 50% of people who have corticosteroid injections go on to have carpal tunnel release surgery within a year.

Corticosteroid injections are more effective than oral corticosteroids. The effect may last for up to 3 months after an injection. But injections are not more effective than either wrist splinting or nonsteroidal anti-inflammatory medications.
