Interactions between your drugs

Major

chloramphenicol promazine

Applies to: chloramphenicol and promazine

GENERALLY AVOID: Coadministration of chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis may increase the risk and/or severity of hematologic toxicity. Serious and fatal blood dyscrasias (aplastic anemia, hypoplastic anemia, thrombocytopenia, granulocytopenia, and bone marrow depression) have been reported after short-term and long-term systemic therapy with chloramphenicol.

MANAGEMENT: Concurrent use of chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis, such as sulfonamides, nucleoside reverse transcriptase inhibitors, procainamide, phenylbutazone, clozapine, and depot formulations of antipsychotic drugs, should be avoided.

Drug and food interactions

Moderate

promazine food

Applies to: promazine

GENERALLY AVOID: Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment. Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines. The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.

MANAGEMENT: Patients should be advised to avoid alcohol during phenothiazine therapy.

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.
