Interactions between your drugs
benztropine FLUoxetine
Applies to: Cogentin (benztropine) and Prozac (fluoxetine)
MONITOR: Delirium has been observed during the coadministration of benztropine and selective serotonin reuptake inhibitors (SSRIs). The mechanism of this potential interaction, if any, has not been determined. There have only been isolated case reports, and concomitant neuroleptic use was common.
MANAGEMENT: Until further data are available, it may be appropriate to monitor patients for evidence of delirium or other unusual psychiatric reactions when benztropine is given with SSRIs, especially if neuroleptic therapy is also administered.

Drug and food interactions
FLUoxetine food
Applies to: Prozac (fluoxetine)
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.

benztropine food
Applies to: Cogentin (benztropine)
GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.
MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
