Hi, You should at once report the matter to your obstetrician if you have not done so. You should also get tested for any infection as cause. The medication needs to be taken as long as the liver function remains high and for sometime after normal values are achieved. Itching can be controlled by applying olive oil or calamine lotion along with an anti-histamine under your doctor s surveillance. Please get adequate treatment and proper diet and rest as your pregnancy needs to be monitored well in view of jaundice. Wish you safe motherhood.
