"For nearly a century, bacteria-fighting drugs known as antibiotics have helped to control and destroy many of the harmful bacteria that can make us sick. But in recent decades, antibiotics have been losing their punch against some types of bac"...
Clinical Trials Experience
CLAFORAN is generally well tolerated. The most common adverse reactions have been local reactions following IM or IV injection. Other adverse reactions have been encountered infrequently.
The most frequent adverse reactions (greater than 1%) are:
Local (4.3%) -Injection site inflammation with IV administration. Pain, induration, and tenderness after IM injection.
Nausea and vomiting have been reported rarely.
Less frequent adverse reactions (less than 1%) are:
Hematologic System -Neutropenia, transient leukopenia, have been reported. Some individuals have developed positive direct Coombs Tests during treatment with CLAFORAN and other cephalosporin antibiotics.
Central Nervous System -Headache.
Liver -Transient elevations in AST, ALT, serum LDH, and serum alkaline phosphatase levels have been reported.
Kidney -As with some other cephalosporins, transient elevations of BUN have been occasionally observed with CLAFORAN.
The following adverse reactions have been identified during post-approval use of CLAFORAN. Because these reactions were reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Central Nervous System -Administration of high doses of beta-lactam antibiotics, including cefotaxime, particularly in patients with renal insufficiency may result in encephalopathy (e.g. impairment of consciousness, abnormal movements and convulsions).
Cephalosporin Class Labeling
In addition to the adverse reactions listed above which have been observed in patients treated with cefotaxime sodium, the following adverse reactions and altered laboratory tests have been reported for cephalosporin class antibiotics: allergic reactions, hepatic dysfunction including cholestasis, aplastic anemia, hemorrhage, and false-positive test for urinary glucose.
Several cephalosporins have been implicated in triggering seizures, particularly in patients with renal impairment when the dosage was not reduced. See DOSAGE AND ADMINISTRATION and OVERDOSAGE. If seizures associated with drug therapy occur, the drug should be discontinued. Anticonvulsant therapy can be given if clinically indicated.

Increased nephrotoxicity has been reported following concomitant administration of cephalosporins and aminoglycoside antibiotics.
Probenecid interferes with the renal tubular transfer of cefotaxime, decreasing the total clearance of cefotaxime by approximately 50% and increasing the plasma concentrations of cefotaxime. Administration of cefotaxime in excess of 6 grams/day should be avoided in patients receiving probenecid (see CLINICAL PHARMACOLOGY, Drug Interactions).
Drug/Laboratory Test Interactions
Cephalosporins, including cefotaxime sodium, are known to occasionally induce a positive direct Coombs' test.
A false-positive reaction for glucose in the urine may occur with copper reduction tests (Benedict's or Fehling's solution or with CLINITEST® tablets), but not with enzyme-based tests for glycosuria. (e.g., CLINISTIX® or TesTape®). There are no reports in published literature that link elevations of plasma glucose levels to the use of cefotaxime.
