How long does it take to work? Metformin does not instantly reduce blood sugar levels. The effects are usually noticeable within 48 hours of taking the medication, and the most significant effects take 4–5 days to occur.
Be sure to take it with meals to reduce the stomach and bowel side effects that can occur – most people take metformin with breakfast and dinner. Extended-release metformin is taken once a day and should be taken at night, with dinner. This can help to treat high glucose levels overnight.

If your blood sugar is high despite medication, it could mean a few things: Your dosage is not high enough, you are not responding to the medication as expected, or your diet, exercise, and lifestyle are not helping enough to control your blood sugar.

The administration of metformin, as glucophage retard, at bedtime instead of supper time may improve diabetes control by reducing morning hyperglycemia.
The vast majority of patients who accidentally take a double dose of their metformin have either no symptoms at all or mild stomach upset like nausea, vomiting, or diarrhea. On the other hand, a large overdose might result in life-threatening effects like lactic acidosis.
Because of this, you'll have trouble clearing sugar from your blood, leading to high levels of glucose. Common symptoms of high blood glucose include increased thirst, frequent urination, increased hunger, and fatigue.
The good news: The side effects do subside for most people. Plus, metformin should start working its magic by the end of the second week. “If somebody is checking their blood sugar at home with a meter, they might notice on average their levels are down maybe 5, maybe 10 points,” says Albanese.
Metformin is a common prescription drug used to treat type 2 diabetes. It can help lower blood sugar and HbA1c levels and is used to help manage weight. It's best to avoid saturated fats, excess alcohol consumption, too much sodium, refined carbohydrates, and processed and added sugars while taking it.
Moreover, metformin as an insulin sensitizer can affect sleep via altering glucose metabolism. Metformin improves the neural glucose resorption and it can affect the nervous system health, and therefore affecting sleep quality.
It should be taken no earlier than 30 minutes before meals. If a meal is skipped, skip the dose for that meal. Do not take more often than directed.
Is Metformin an Effective Weight Loss Pill? No. The amount of weight you're likely to lose is low. In one diabetes prevention study, 29% of people lost 5% or more of their body weight and just 8% lost around 10%.
Even in studies that indicated weight loss, the results were modest. One of the most extensive studies to date, performed by the Diabetes Prevention Program (DPP), tested metformin in people with prediabetes (those at risk for developing T2D). People randomly assigned metformin lost an average of 4-7 pounds.
