There is no exact time frame for the removal of stones from the body, because the absorption and sensitivity of the drug is different for each person. The location of the stone is different for each person, and the size of the stone and the nature of the stone may affect the time it takes for the stone to pass out of the body. If the stone is well located and not embedded in the urethral stricture, and the stone is not very large, it can be excreted within 24-48 hours after oral administration of Eucerin. It is also necessary to combine with drinking more water, drinking more than 2000 ml of water, and exercising more to increase the urine volume, which will play a flushing effect on the urethra and promote the discharge of the stone, which will also help.
