MONITOR: Concomitant use of ashwagandha with other agents that are known to induce hepatotoxicity may theoretically increase the risk of hepatotoxicity. There are case reports of adverse effects on liver functions associated with ashwagandha use. In a case report, a 20-year-old man in Japan developed liver dysfunction and hyperbilirubinemia after using ashwagandha in combination with multiple antianxiety drugs. In additional case reports, three men and two women, age range 21 to 62 years who reportedly took supplements containing 450 to 1,350 mg ashwagandha daily over the course of one week to four months when signs of liver injury, such as jaundice, pruritus, nausea, lethargy, abdominal discomfort, and hyperbilirubinemia, appeared.

MANAGEMENT: Liver function tests should be monitored, and patients should be advised to report any symptoms such as abdominal pain, jaundice, dark urine, light stools, fever, or unusual fatigue.

Drug and food interactions

Moderate

pravastatin food

Applies to: pravastatin

MONITOR: Concomitant use of statin medication with substantial quantities of alcohol may increase the risk of hepatic injury. Transient increases in serum transaminases have been reported with statin use and while these increases generally resolve or improve with continued therapy or a brief interruption in therapy, there have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins. Patients who consume substantial quantities of alcohol and/or have a history of liver disease may be at increased risk for hepatic injury. Active liver disease or unexplained transaminase elevations are contraindications to statin use.

MANAGEMENT: Patients should be counseled to avoid substantial quantities of alcohol in combination with statin medications and clinicians should be aware of the increased risk for hepatotoxicity in these patients.

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.
