Hello, adult oral: 8 ~ 10 mg/kg daily, administered at breakfast and dinner. The shortest course of treatment is 6 months. After 6 months, if the ultrasound examination and cholecystography do not improve, you can stop taking the medicine. If the stone has been partially dissolved, continue to take the medicine until the stone is completely dissolved.

55 kg, 50 mg per tablet? : 55 *10/50 =11,that is, 4 to 5 tablets twice a day.

Wish you good health.
