  • Drying medications (Anticholinergic drugs) interacts with SYRIAN RUE

    Syrian rue can increase a chemical in the body called acetylcholine. Acetylcholine plays a big part in many important body functions. Some medications, called anticholinergic drugs, block the effects of acetylcholine in the body. Taking Syrian rue might decrease the effects of anticholinergic drugs.

  • Caffeine interacts with SYRIAN RUE

    Syrian rue contains a chemical called harmaline. Taking caffeine with harmaline might increase the risk for tremors.

  • Various medications used for glaucoma, Alzheimer disease, and other conditions (Cholinergic drugs) interacts with SYRIAN RUE

  • Medications changed by the liver (Cytochrome P450 2D6 (CYP2D6) substrates) interacts with SYRIAN RUE

    Some medications are changed and broken down by the liver. Syrian rue might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.

  • Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates) interacts with SYRIAN RUE
