Antibiotics (applies to Keflex) colitis

Major Potential Hazard, Moderate plausibility. Applicable conditions: Colitis/Enteritis (Noninfectious)

Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Moderate

Beta-lactams (oral) (applies to Keflex) renal dysfunction

Moderate Potential Hazard, High plausibility.

Most beta-lactam antibiotics are eliminated by the kidney as unchanged drug and, in some cases, also as metabolites. The serum concentrations of beta-lactam antibiotics and their metabolites may be increased and the half-lives prolonged in patients with impaired renal function. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment as well as severity of infection in accordance with the individual product package labeling. Renal function tests should be performed periodically during prolonged and/or high-dose therapy, since nephrotoxicity and alterations in renal function have occasionally been associated with the use of these drugs.

Cephalosporins (applies to Keflex) diabetes

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Diabetes Mellitus

Use of cephalosporins may result in a false-positive reaction for glucose in urine with certain methods (e.g., Clinitest tablets). Glucose tests based on enzymatic glucose oxidase reactions are recommended for patients receiving cephalosporins.

Cephalosporins (applies to Keflex) dialysis

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: hemodialysis

Most cephalosporin antibiotics are removed by hemodialysis. Doses should either be scheduled for administration after dialysis or supplemental doses be given after dialysis. Cefonicid, cefixime, and ceftriaxone are not significantly removed by hemodialysis.

Cases of hepatitis have been reported with the use of certain cephalosporins. Transient rise in AST, ALT, and alkaline phosphatase levels have also been observed. Caution and monitoring are recommended when these agents are prescribed to patients with hepatic disorders.

Cephalosporins (applies to Keflex) prolonged PT

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease, Coagulation Defect, Malnourished, Renal Dysfunction, Vitamin K Deficiency

Cephalosporins may be associated with reduced prothrombin activity/prolonged prothrombin time. Risk factors include renal or liver dysfunction, poor nutritional state, prolonged antimicrobial therapy, and previously stabilized on/receiving anticoagulant therapy. Prothrombin time should be monitored in at-risk patients and managed as indicated (e.g., exogenous vitamin K administered).

Cephalosporins (applies to Keflex) seizure disorders

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Seizures

Cephalosporins have been implicated in triggering seizures. Nonconvulsive status epilepticus, encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonia have been reported with cephalosporins particularly in patients with a history of epilepsy and/or when recommended dosages of cephalosporins were exceeded due to renal dysfunction. Dosage should be adjusted based on the degree of renal function. Anticonvulsant therapy should be continued in patients with known seizure disorders. If CNS adverse reactions including seizures occur, patients should undergo a neurological evaluation to determine whether treatment should be discontinued.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
