While nasal congestion isn’t a common side effect of Metformin, it could potentially arise due to an allergic reaction in sensitive individuals, leading to inflammation of nasal passages.
Metformin has not been commonly linked to nasal congestion. If experienced, it could be an atypical allergic response. Most side effects are gastrointestinal.
