I think I od on metformin should I go to er

I am Dr. Arun and will be helping you today.

Did you take extra dose of Metformin?

What is your present blood sugar?

Customer: replied 3 years ago.

I take it for pcos. Yes extra dose


The peak action of Metformin reaches in around 3-4 hours and effect may last 12-24 hours. So there is definite chance of fall of blood sugar in this duration. The blood sugar levels would need monitoring in this duration. So it would be recommended that you are kept under medical observation in this duration. So going to ER would be strongly advised.

Please feel free for your follow up questions.

I would be happy to assist you further, if you need any more information.

Thanks for using Just Answer.

I feel ok right now and that I take it for pcos could still cause sugar to fall?


Metformin usually does not low blood sugar but with an additional dose, this may occur. So a blood sugar monitoring may be required for the cautionary purpose. Since you take it for PCOS, you would not have blood sugar monitoring device. So a blood sugar check at 3 hours would be good for precaution. The symptoms of low blood sugar are; cold sweats, cool pale skin, tremor, anxious feeling, unusual tiredness or weakness, confusion, difficulty in concentration, excessive hunger, temporary vision changes, headache or nausea. We need to work on the highly cautionary side for medication overdose.

It is privilege assisting you.
