    In a randomized trial, patients with chronic hepatitis C who were being treated with Peg-interferon-alpha 2b and ribavirin were randomly assigned to receive L-carnitine (2 grams twice a day) or no L-carnitine (control group). Compared with the control group, fewer patients in the L-carnitine group had to reduce the medication dosage or discontinue treatment because of side effects such as anemia or a decline in the white blood cell count.1
