Inflammatory
Initial treatment for all patients is an oral non-steroidal anti-inflammatory drug (NSAID) for 10 to 14 days. In patients at high risk of gastrointesinal (GI) complications (e.g., history of GI bleeding, age >60 years, concomitant corticosteroid or anticoagulants), a COX-2 inhibitor (e.g., celecoxib) instead of a standard non-selective NSAID, and preventive measures such as prophylactic use of a proton-pump inhibitor (PPI) for the same time period, should be considered.[28]Gabriel SE, Jaakkimainen L, Bombardier C. Risk of serious gastrointestinal complications related to use of nonsteroidal anti-inflammatory drugs: a meta-analysis. Ann Intern Med. 1991 Nov 15;115(10):787-96.

COX-2 inhibitors confer a reduced risk of gastrointestinal toxicity compared with traditional NSAIDs, and co-prescription of PPIs can reduce the risk even further, especially if the patient is also on low-dose aspirin.[31]Lanas A, Ferrandez A. NSAID-induced gastrointestinal damage: current clinical management and recommendations for prevention. Chin J Dig Dis. 2006;7(3):127-33.

The choice of NSAID/COX-2 inhibitor should be adapted to the patient profile.[32]National Institute for Health and Care Excellence. Osteoarthritis: care and management. Dec 2020 [internet publication].

A corticosteroid injection with local anaesthetic into the affected costochondral joints should be given to patients unresponsive to or intolerant of NSAIDs. This is usually performed by a specialist (e.g., rheumatologist).
A retrospective study suggested that corticosteroid injections and sulfasalazine could be helpful in the treatment of costochondritis.[3]Freeston J, Karim Z, Lindsay K, et al. Can early diagnosis and management of costochondritis reduce acute chest pain admissions. J Rheumatol. 2004 Nov;3(11):2269-71.

However, the study was limited due to the small number of subjects, retrospective design, and the lack of control group. In addition, patients treated with sulfasalazine continued to receive corticosteroid injections, thereby limiting the effective evaluation of sulfasalazine.
If pain persists, the diagnosis should be re-evaluated and referral to a rheumatologist considered.

Antibiotics alone are usually ineffective because of the poor blood supply to cartilage, and surgical debridement and/or drainage (when such a collection exists and is amenable to aspiration) is the treatment of choice.[10]Ontell FK, Moore EH, Shepard JO, et al. The costal cartilages in health and disease. Radiographics. 1997 May-Jun;17(3):571-7.

This should be done with appropriate antibiotic cover and wound care.
Early drainage plus intravenous antibiotics may be sufficient for the management of bacterial costochondritis in intravenous drug users.[33]Zapatero J, López Longo J, Monteagudo I, et al.

Bacterial costochondritis complicating thoracic surgery generally requires debridement.[33]Zapatero J, López Longo J, Monteagudo I, et al. Costal chondritis in heroin addicts: a comparative study with postsurgical chondritis. Br J Dis Chest. 1988 Oct;82(4):341-6.
