I bought a pack of cimetidine tablets and noticed they smell bad, like rotten eggs. is this normal or are they off? exp date is 8/2015.

Characteristic: Cimetidine notoriously has a characteristic odor due to its slight sulfur-mercaptan odor, which has an egg-like odor.

Very inexpensive.: May be a bad lot, or byproduct in manufacuring. Still should be good, but you can complain to your pharmacist and might get new product. But first ask them if they smell like that. Generic american product does not have this and is available over the counter without a prescription needed!
