Interactions between your drugs

Moderate

sulfamethoxazole indium oxyquinoline In-111

Applies to: Bactrim (sulfamethoxazole / trimethoprim) and indium oxyquinoline in-111

MONITOR: Certain medications may decrease chemotaxis and cause false-negative results with Indium In-111-labeled leukocyte studies.

MANAGEMENT: Clinicians should be aware of possible diagnostic interference in patients who are on long-term antibiotic treatment, corticosteroids, interleukin-2, parenteral nutrition, or high doses or supratherapeutic concentrations of lidocaine or procainamide.

Drug and food interactions

Moderate

sulfamethoxazole food

Applies to: Bactrim (sulfamethoxazole / trimethoprim)

MONITOR: Two cases have been reported in which patients on sulfamethoxazole-trimethoprim therapy, after consuming beer, reported flushing, heart palpitations, dyspnea, headache, and nausea (disulfiram - alcohol type reactions). First-generation sulfonylureas have been reported to cause facial flushing when administered with alcohol by inhibiting acetaldehyde dehydrogenase and subsequently causing acetaldehyde accumulation. Since sulfamethoxazole is chemically related to first-generation sulfonylureas, a disulfiram-like reaction with products containing sulfamethoxazole is theoretically possible. However, pharmacokinetic/pharmacodynamic data are lacking and in addition, the two reported cases cannot be clearly attributed to the concomitant use of sulfamethoxazole-trimethoprim and alcohol.

MANAGEMENT: Patients should be alerted to the potential for this interaction and although the risk for this interaction is minimal, caution is recommended while taking sulfamethoxazole-trimethoprim concomitantly with alcohol.

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.
