Drug Interactions
This information should not be interpreted without the help of a healthcare provider. If you believe you are experiencing an interaction, contact a healthcare provider immediately. The absence of an interaction does not necessarily mean no interactions exist.
DrugInteraction
1,2-BenzodiazepineThe risk or severity of CNS depression can be increased when Dimetacrine is combined with 1,2-Benzodiazepine.
AbacavirAbacavir may decrease the excretion rate of Dimetacrine which could result in a higher serum level.
AcarboseDimetacrine may decrease the hypoglycemic activities of Acarbose.
AcebutololDimetacrine may decrease the antihypertensive activities of Acebutolol.
AceclofenacThe risk or severity of gastrointestinal bleeding can be increased when Dimetacrine is combined with Aceclofenac.
