Does Saxenda cause low blood sugar?

Yes, and it is on the label rather than only in reports: low blood sugar appears among the common adverse reactions in Saxenda's FDA prescribing information, published 2026-06-15. Listed means it was seen often enough in the trials to be printed, not that it happens to everyone. Less often than people fear, but not never. These drugs prompt insulin release in response to a meal rather than regardless of one, so on their own they do not usually push blood sugar far down — yet the labels still say they can cause it. The risk rises sharply alongside insulin or a sulfonylurea, where the two effects add up, and one of these labels records it in children who did not have diabetes. Treat the symptoms as real whatever else you take. It does not follow the dose schedule, so it does not come and go with dose increases. What helps first: knowing whether anything else you take is insulin or a sulfonylurea — glipizide, glimepiride, glyburide. If so, this is a conversation with the prescriber before the next dose increase, not after a bad episode. It stops being ordinary at a specific line: confusion, seizure, or being unable to treat it yourself. Anyone on insulin or a sulfonylurea starting one of these should have the doses of those reviewed rather than left as they were.
