Bactocill (oxacillin) Disease Interactions

There are 4 disease interactions with Bactocill (oxacillin):

Major

Penicillinase-Resistant Pcns (Includes Bactocill) ↔ Marrow Toxicity

Severe Potential Hazard, Moderate plausibility

Applies to: Thrombocytopenia, Neutropenia

The use of penicillinase-resistant penicillins has been associated with adverse hematologic effects, including neutropenia, leukopenia, granulocytopenia and thrombocytopenia, particularly when given in high parenteral dosages. Agranulocytosis and prolonged bleeding time have been reported rarely. Therapy with penicillinase-resistant penicillins should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow depression, and hematopoietic function should be monitored. Blood counts with differential should be performed prior to initiation of therapy and 1 to 3 times weekly during therapy. Hematologic abnormalities are generally reversible and resolve within several days to two weeks following discontinuation of therapy.

Antibiotics (Includes Bactocill) ↔ Colitis

Moderate Potential Hazard, Moderate plausibility

Applies to: Colitis/Enteritis (Noninfectious)

Pseudomembranous colitis has been reported with most antibacterial agents and may range in severity from mild to life-threatening, with an onset of up to two months following cessation of therapy. Antibiotic therapy can alter the normal flora of the colon and permit overgrowth of Clostridium difficile, whose toxin is believed to be a primary cause of antibiotic- associated colitis. The colitis is usually characterized by severe, persistent diarrhea and severe abdominal cramps, and may be associated with the passage of blood and mucus. The most common culprits are clindamycin, lincomycin, the aminopenicillins (amoxicillin, ampicillin), and the cephalosporins. Therapy with broad-spectrum antibiotics and other agents with significant antibacterial activity should be administered cautiously in patients with a history of gastrointestinal diseases, particularly colitis. There is some evidence that pseudomembranous colitis, if it occurs, may run a more severe course in these patients and that it may be associated with flares in their underlying disease activity. The offending antibiotic(s) should be discontinued if significant diarrhea occurs during therapy. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically. A large bowel endoscopy may be considered to establish a definitive diagnosis in cases of severe diarrhea.

Oxacillin (Includes Bactocill) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

Oxacillin is partially converted by the liver to active and inactive metabolites, and both parent drug and metabolites are eliminated by the kidney. The serum concentrations of oxacillin and its metabolites may be increased and the half-lives prolonged in patients with significantly impaired renal function. In general, dosage adjustments are not necessary in either renal or hepatic impairment, but the lower range of the usual recommended dosage may be appropriate in patients with severe renal impairment (CrCl < 10 mL/min). Renal and liver function tests should be performed periodically during prolonged therapy.

Oxacillin (Includes Bactocill) ↔ Sodium/Potassium

Moderate Potential Hazard, High plausibility

Applies to: Congestive Heart Failure, Fluid Retention, Hypernatremia, Hypertension, Hypokalemia

Each gram of parenteral oxacillin sodium contains approximately 64 to 71 mg (2.8 to 3.1 mEq) of sodium and is buffered with 40 mg of dibasic sodium phosphate. Each 250 mg capsule of oxacillin sodium contains approximately 16 mg (0.7 mEq) of sodium, and each teaspoonful of the 250 mg/5 mL oral solution contains approximately 18 mg (0.8 mEq) of sodium. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention. In addition, hypokalemia has been reported rarely during therapy with the penicillinase-resistant penicillins, which may be particularly important to bear in mind when treating patients with low potassium reserves or fluid and electrolyte imbalance. Clinical monitoring of electrolytes is recommended if these agents are used for prolonged periods.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

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.

Do not stop taking any medications without consulting your healthcare provider.
