Drug-induced cholestasis is a form of drug-induced liver injury (DILI) characterized by impaired bile flow caused by medications, herbal supplements, or dietary supplements. Cholestasis literally means "bile standing still" -- the normal flow of bile from the liver to the intestine is disrupted, leading to accumulation of bile components in the blood. It accounts for approximately 20-40% of all drug-induced liver injury cases.
This condition is particularly relevant for our diverse Flushing community, as traditional herbal remedies and supplements -- commonly used in Asian cultures -- are increasingly recognized as significant causes of DILI. Many patients do not report herbal supplement use to their doctors, making a thorough medication history essential for diagnosis.
Common medications that can cause cholestasis include certain antibiotics (amoxicillin-clavulanate, erythromycin), anabolic steroids, oral contraceptives, anti-seizure drugs, and some cholesterol medications. At Dr. Jing Tong Gastroenterology, we systematically evaluate medication histories and perform comprehensive liver testing to identify the cause and guide treatment.

Yes. Herbal and dietary supplements are the second most common cause of drug-induced liver injury in the US, after acetaminophen. Many herbal products are not regulated and may contain hidden ingredients. Always inform your doctor about all supplements you take.
Generally, you should never re-take a medication that caused liver injury, as rechallenge can cause a more severe reaction. Dr. Tong will document the offending drug and help identify safe alternatives for your medical needs.
Both can cause jaundice and similar symptoms. Drug-induced cholestasis is caused by medication effects on liver cells, while bile duct blockage is a physical obstruction (stone, tumor). Imaging (ultrasound, MRCP) is essential to distinguish between the two.
Never stop prescribed medications without consulting your doctor first, as abrupt discontinuation of some drugs can be dangerous. If you notice jaundice, dark urine, or severe itching, contact Dr. Tong's office promptly for evaluation and guidance.
