What are the indications, contraindications, dosages and side effects of Gelusil? ## From the information I am finding, Gelusil is used to treat heartburn and gas. It contains: 200 mgs of Aluminum Hydroxide, 200mgs of Magnesium Hydroxide and 25mgs of Simethicone. The product packaging says to chew 2 to 4 tablets hourly as symptoms persist or as directed by a physician. Do you have any other questions? ## The expiration date on the packaging of my gelusil chewable tablets just got torn away from the strip, but the manufacturing date is July 2016. Does anyone know when they expire?
