Interactions between your drugs
diphenhydrAMINE pilocarpine ophthalmic
Applies to: diphenhydramine / ibuprofen, Ocu-Carpine (pilocarpine ophthalmic)
MONITOR: Theoretically, anticholinergic agents and other agents with significant anticholinergic activity (e.g., antihistamines, antispasmodics, neuroleptics, phenothiazines, skeletal muscle relaxants, tricyclic antidepressants, class IA antiarrhythmics especially disopyramide) may antagonize the effects of topically administered cholinergic agents such as acetylcholine, carbachol, demecarium, echothiophate, isoflurophate, physostigmine, and pilocarpine. The proposed mechanism involves opposing pharmacodynamic action on muscarinic receptor sites in ocular tissue. This interaction is sometimes desirable and is the basis for using atropine in the treatment of excessive muscarinic side effects and cholinergic crisis induced by cholinergic overdose.
MANAGEMENT: Patients receiving long-term therapy with anticholinergic agents should be monitored for potentially diminished therapeutic (miotic) response to ophthalmic cholinergic therapy, and dosages adjusted as necessary.

Drug and food interactions
ibuprofen food
Applies to: diphenhydramine / ibuprofen
GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.
MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

diphenhydrAMINE food
Applies to: diphenhydramine / ibuprofen
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.

Therapeutic duplication warnings are only returned when drugs within the same group exceed the recommended therapeutic duplication maximum.
Drug Interaction Classification
Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. | |
Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. | |
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. | |
No interaction information available. |
