WARNINGS Spectinomycin hydrochloride is not effective in the treatment of syphilis. Antibiotics used in high doses for short periods of time to treat gonorrhea may mask or delay the symptoms of incubating syphilis. Since the treatment of syphilis demands prolonged therapy with any effective antibiotic, patients being treated for gonorrhea should be closely observed clinically. All patients with gonorrhea should have a serologic test for syphilis at the time of diagnosis. Patients treated with spectinomycin hydrochloride should have a follow-up serologic test for syphilis after three months.
ADVERSE REACTIONS The following reactions were observed during the single dose clinical trials: soreness at the injection site, urticaria, dizziness, nausea, chills, fever and insomnia. During multiple dose subchronic tolerance studies in normal human volunteers, the following were noted: a decrease in hemoglobin, hematocrit and creatinine clearance; elevation of alkaline phosphatase, BUN and SGPT. In single and multiple dose studies in normal volunteers, a reduction in urine output was noted. Extensive renal function studies demonstrated no consistent changes indicative of renal toxicity. A few cases of anaphylaxis or anaphylactoid reactions have been reported. If serious allergic reactions occur, the usual agents (epinephrine, corticosteroids, and/or antihistamines) should be available for emergency use. In cases of severe anaphylaxis, airway support and oxygen may also be required.
