Driving on Glucophage: is it safe?

For most adults, Glucophage is compatible with driving once a stable response is established, but the first dose and dose changes deserve extra caution.
Side effects that affect driving
Among the side effects of Metformin, dizziness, sleepiness, blurred vision and slowed reactions are the ones most relevant for driving. Most users do not develop these at 500mg, 850mg, 1000mg; those who do typically notice the effect within hours of dosing and during the first weeks of therapy.
Practical guidance
According to the prescribing information for Metformin, until you know how you respond to Glucophage, you should avoid driving. After several doses with no relevant side effects, normal driving is usually safe. Metformin reduces hepatic glucose production through inhibition of mitochondrial complex I, which raises the cellular AMP/ATP ratio and activates AMP-activated protein kinase. Combining Glucophage with alcohol or sedating medications adds risk and is not advised before driving.
