Evidence for the Use of Intramuscular
Injections in Outpatient Practice
MARK SHATSKY, DO, Providence Medical Group, Portland, Oregon
There are few studies comparing the outcomes of patients who are treated with oral versus
intramuscular antibiotics, corticosteroids, nonsteroidal anti-inflammatory drugs, or vitamin
B . 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 anti-
biotics are the treatment of choice for the outpatient treatment of pneumonia and most other
outpatient bacterial infections. Oral corticosteroids are as effective as intramuscular cortico-
steroids and are well-tolerated by most patients. High daily doses of oral vitamin B with ongo-

ing 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.

SORT: KEY RECOMMENDATIONS FOR PRACTICE
Oral antibiotics are recommended for the outpatient treatment of pneumonia.
Intramuscular penicil in G benzathine is the recommended treatment of choice for Treponema pal idum infections, and intramuscular ceftriaxone (Rocephin) is recommended for Neisseria gonorrhoeae infections and pelvic inflammatory disease.
Intramuscular penicil in is the recommended treatment for group A beta-hemolytic streptococcal pharyngitis when the oral route cannot be used.
Intramuscular epinephrine is the recommended drug of choice for anaphylactic reactions.
Oral vitamin B at a dosage of 2,000 mcg per day is an effective treatment for B deficiency Intramuscular ketorolac (Toradol, no longer available for injection) is no more effective for pain syndromes than oral ibuprofen or other oral nonsteroidal anti-inflammatory agents.
