DULoxetine turmeric

Applies to: Cymbalta (duloxetine) and turmeric

MONITOR: Turmeric may potentiate the bleeding risk associated with drugs that interfere with platelet function or coagulation. In vitro data suggest that curcumin, an active constituent of turmeric, may inhibit platelet-activating factor and platelet aggregation. Isolated case reports have also described increases in INR following initiation of turmeric-containing products in patients treated with a vitamin K antagonist such as warfarin. However, pharmacologic effects of turmeric preparations may be highly variable due to inconsistencies in formulation and potency of commercial herbal products.

MANAGEMENT: Caution is advised when turmeric-containing products are used concomitantly with drugs that affect hemostasis such as anticoagulants, antiplatelet agents, nonsteroidal anti-inflammatory drugs, serotonin reuptake inhibitors, and thrombolytic agents. Clinical and laboratory observation for hematologic complications is recommended.

DULoxetine food

Applies to: Cymbalta (duloxetine)

GENERALLY AVOID: Use of duloxetine in conjunction with chronic alcohol consumption may potentiate the risk of liver injury. Duloxetine alone can increase serum transaminase levels. In clinical trials, 0.3% of patients discontinued duloxetine due to liver transaminase elevations. The median time to detection was about two months. Three duloxetine-treated patients had liver injury as manifested by transaminase and bilirubin elevations, with evidence of obstruction. Substantial intercurrent ethanol use was present in each of these cases, which may have contributed to the abnormalities observed. Duloxetine does not appear to enhance the central nervous system effects of alcohol. When duloxetine and ethanol were administered several hours apart so that peak concentrations of each would coincide, duloxetine did not increase the impairment of mental and motor skills caused by alcohol.

MANAGEMENT: Due to the risk of liver injury, patients prescribed duloxetine should be counseled to avoid excessive use of alcohol. Duloxetine should generally not be prescribed to patients with substantial alcohol use.

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.
