ABSTRACT: There are few studies comparing the outcomes of patients who are treated with oral versus intramuscular antibiotics, corticosteroids, nonsteroidal anti-inflammatory drugs, or vitamin B12. This may lead to confusion about when the intramuscular route is indicated. For example, intramuscular ceftriaxone for Neisseria gonorrhoeae infection and intramuscular penicillin G benzathine for Treponema pallidum infection are the treatments of choice. However, oral antibiotics are the treatment of choice for the outpatient treatment of pneumonia and most other outpatient bacterial infections. Oral corticosteroids are as effective as intramuscular corticosteroids and are well-tolerated by most patients. High daily doses of oral vitamin B12 with ongoing clinical surveillance appear to be as effective as intramuscular treatment. Few data support choosing intramuscular ketorolac over an oral nonsteroidal anti-inflammatory drug unless the patient is unable to tolerate an oral medication. For other indications, the intramuscular route should be considered only when the delivery of a medication must be confirmed, such as when a patient cannot tolerate an oral medication, or when compliance is uncertain.
ABSTRACT: Injections are valuable procedures for managing musculoskeletal conditions commonly encountered by family physicians. Corticosteroid injections into articular, periarticular, or soft tissue structures relieve pain, reduce inflammation, and improve mobility. Injections can provide diagnostic information and are commonly used for postoperative pain control. Local anesthetics may be injected with corticosteroids to provide additional, rapid pain relief. Steroid injection is the preferred and definitive treatment for de Quervain tenosynovitis and trochanteric bursitis. Steroid injections can also be helpful in controlling pain during physical rehabilitation from rotator cuff syndrome and lateral epicondylitis. Intra-articular steroid injection provides pain relief in rheumatoid arthritis and osteoarthritis. There is little systematic evidence to guide medication selection for therapeutic injections. The medication used and the frequency of injection should be guided by the goal of the injection (i.e., diagnostic or therapeutic), the underlying musculoskeletal diagnosis, and clinical experience. Complications from steroid injections are rare, but physicians should understand the potential risks and counsel patients appropriately. Patients with diabetes who receive periarticular or soft tissue steroid injections should closely monitor their blood glucose for two weeks following injection.
