Bupropion and Insulin Glargine are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Bupropion and Insulin Glargine 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.
