Insulin Glargine: Hypoglycaemia is the most important adverse effect of any insulin and can be severe in case of missed meals, prolonged exercise, alcohol intake or interaction with other glucose-lowering agents. Famotidine: Famotidine is generally well tolerated.
Frequently asked questions
Is Insulin Glargine better than Famotidine? ▾
Insulin Glargine and Famotidine are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Insulin Glargine and Famotidine be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
Do they have the same side-effect profile? ▾
No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
