Edit list (add/remove drugs)

Interactions between your drugs

Moderate

mephobarbital methylene blue

Applies to: mephobarbital and Urolene Blue (methylene blue)

MONITOR: Limited clinical data suggest that nonselective monoamine oxidase inhibitors (MAOIs) may enhance or prolong the central nervous system effects of barbiturates. The mechanism of interaction is unknown, but may involve inhibition of barbiturate metabolism by MAOIs. Somnolence, dizziness, ataxia, and semi-consciousness have been reported.

MANAGEMENT: Until more information is available, patients should be monitored for increased barbiturate effects during coadministration with an MAOI or other agents that possess MAOI activity such as furazolidone, linezolid, methylene blue, and procarbazine.

Drug and food interactions

Major

mephobarbital food

Applies to: mephobarbital

GENERALLY AVOID: Concurrent acute use of barbiturates and ethanol may result in additive CNS effects, including impaired coordination, sedation, and death. Tolerance of these agents may occur with chronic use. The mechanism is related to inhibition of microsomal enzymes acutely and induction of hepatic microsomal enzymes chronically.

MANAGEMENT: The combination of ethanol and barbiturates should be avoided.

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.
