Hi Doctor, my three year old son has been scratching his rectum, and some times grinding his teeth since last week. I doubted it to be due to worms in his stomach and on the 9th of this month gave him 10ml of Bendex syrup. Still I could see him having discomfort when sitting down, he constantly moves his buttocks and scratches his rectum. Yesterday that is the 16th I took him to a doctor , who prescribed few tablets - vomirid-MD, zofton-OZ, sporlac-DS and Epispas. Now I want to know if these are for worm eradication?
