Drug-induced cholestasis
Definition
Drug-induced cholestasis is a blockage in the flow of bile
from the liver that occurs with medication use.
Alternative Names
Cholestasis - drug-induced
Causes
Bile is produced in the liver, moved to the gallbladder, and released into the gut through the biliary tract
. It helps the body digest fats.
Certain drugs can slow or stop the flow of bile from the liver to the gallbladder and gut, which may damage the liver.
Many drugs can cause cholestasis, including:
- Ampicillin and other penicillin-based antibiotics
- Anabolic steroids
- Chlorpromazine
- Cimetidine
- Erythromycin
- Gold salts
- Imipramine
- Nitrofurantoin
- Oral contraceptives
- Prochlorperazine
- Sulindac
- Tobutamide
Other medications can also cause cholestasis in some people.
Symptoms
- Fever or rash from the drug
- Itching
- Nausea
- Pain in the upper right part of the abdomen
- Very dark urine
- Very pale stools
- Vomiting
- Yellow skin or eyes (jaundice
)
Exams and Tests
High bilirubin
and alkaline phosphatase
.
Treatment
If medication is causing the cholestasis, the doctor will probably tell you to stop taking the drug and will prescribe an alternative, if possible. DO NOT stop taking medications on your own without talking to your doctor. There is no medicine to reverse drug-induced cholestasis.
Outlook (Prognosis)
Most patients recover, but severe cases may lead to liver failure. Drug-induced cholestasis usually reverses after you stop taking the medication or drug. However, it may take many months for cholestasis to get better.
Possible Complications
- Diarrhea
- Poor absorption of fat and fat-soluble vitamins
- Severe itching
When to Contact a Medical Professional
Call your health care provider if you have persistent itching or notice that your skin or eyes are yellow.
