Multi-receptor incretin drugs are associated with an increased risk of adverse events (primarily gastrointestinal) compared to placebo, but do not significantly increase the risk of serious adverse events.

Be aware that multi-receptor incretin drugs commonly cause gastrointestinal side effects like nausea, which may lead to discontinuation for some. However, the risk of serious health events is not significantly higher than placebo. Discuss potential side effects with your doctor and report any severe or persistent symptoms.
