Interactions between your drugs
chlorzoxazone ashwagandha
Applies to: Eze DS (chlorzoxazone) and ashwaganda
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
chlorzoxazone food
Applies to: Eze DS (chlorzoxazone)
GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents such as chlorzoxazone. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills. In addition, in one small study, watercress was reported to increase chlorzoxazone peak concentrations, AUC, and half-life. The proposed mechanism is inhibition of CYP450 2E1 metabolism. The clinical significance is unknown.
MANAGEMENT: Patients receiving chlorzoxazone should be advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how chlorzoxazone affects them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities. Watercress should be avoided if an interaction is suspected; e.g., excess sedation, nausea, or headache occurs.
