Interactions between your drugs

Moderate

omeprazole halazepam

Applies to: Prilosec (omeprazole) and halazepam

MONITOR: Omeprazole may increase the pharmacologic effects and serum levels of certain benzodiazepines via hepatic enzyme inhibition. Diazepam and triazolam are the only benzodiazepines that have been specifically studied in this regard.

MANAGEMENT: Patient should be observed for increased sedation. Reduced benzodiazepine dosage may be indicated, especially in the elderly. Benzodiazepines not metabolized via oxidation (i.e., lorazepam, oxazepam, temazepam) are not expected to interact and may be considered as alternatives.

Drug and food interactions

Moderate

halazepam food

Applies to: halazepam

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

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.
