Dynapen (dicloxacillin) Disease Interactions
There are 4 disease interactions with Dynapen (dicloxacillin):
Antibiotics (Includes Dynapen) ↔ Colitis
Severe 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 several weeks 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.
Penicillinase-Resistant Pcns (Includes Dynapen) ↔ Marrow Toxicity
Severe Potential Hazard, Moderate plausibility
Applies to: Neutropenia, Thrombocytopenia
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.
Diclox-Methacillin (Includes Dynapen) ↔ Cystic Fibrosis
Moderate Potential Hazard, High plausibility
Applies to: Cystic Fibrosis
The penicillinase-resistant penicillins, dicloxacillin and methicillin, are both eliminated by the kidney. Renal elimination of these penicillins has been shown to increase in patients with cystic fibrosis, resulting in decreased peak serum drug concentrations and AUCs. Clinicians should be cognizant of these effects when prescribing or administering the antibiotics to patients with cystic fibrosis.
Dicloxacillin (Includes Dynapen) ↔ Sodium
Moderate Potential Hazard, High plausibility
Applies to: Congestive Heart Failure, Fluid Retention, Hypernatremia, Hypertension
Each 250 mg capsule of dicloxacillin sodium contains approximately 14 mg (0.6 mEq) of sodium, and each teaspoonful of the 62.5 mg/5 mL oral suspension contains approximately 67 mg (2.9 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.

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. |
