Brief Answer:
Consult your treating doctor.

Detailed Answer:
Hi,

Thanks for your question.
Noted your concern.

Watch for symptoms like abdominal discomfort, nausea, vomiting, breathing difficulty.
If these symptoms develop consult ER immediately.
These are the symptoms of Lactic acidosis. Which is a serious complication of Metaformin overdose especially in patients with kidney problem.
But possibility of Lactic acidosis is extremely rare.

If there are no symptoms skip next dose of medicine and consult your treating doctor.

Hope this helps you.

Regards,
Dr Abhay Mali.
