Why Shouldn't You Stop Taking Metformin? Metformin works by decreasing the amount of sugar your liver releases into your blood, making your body more sensitive to insulin's effects. If you suddenly discontinue use, it can lead to dangerously high blood sugar levels.
Risks of stopping metformin
If left untreated, high blood glucose levels can lead to complications, such as: impaired vision, or diabetic retinopathy. kidney problems, or diabetic nephropathy. nerve damage, or diabetic neuropathy.
For patients who are already on metformin, I do not decrease the dose unless the A1c is 6.0% or less. I might reduce the dose by half every 3 months, as long as the A1c stays at 6.0% or less. I stop the final 500 mg of metformin when the A1c is 6.0% or less for at least 3 months.

Missing doses of oral diabetes medications frequently can lead to serious health complications, some of which may require hospitalization. This also increases the overall cost of your treatment. Potential complications include nerve damage, as well as eye, kidney, or heart disease.
In general, for diabetes medications including oral hypoglycemic agents (e.g., metformin) and insulin, if you miss one dose, take the next one as soon as you remember it. However, if you remember close to the time of the next dose, then skip it and take the next dose instead. Do NOT double the dose.
It is recommended that metformin should be discontinued once eGFR falls below 30 ml/min/1.73 m2 and to decrease the metformin dose in mild to moderate renal impairment (eGFR 30–60 ml/min/1.73 m2).
Metformin lowers your blood sugar levels by improving the way your body handles insulin. It's usually prescribed for diabetes when diet and exercise alone have not been enough to control your blood sugar levels.
The administration of metformin, as glucophage retard, at bedtime instead of supper time may improve diabetes control by reducing morning hyperglycemia.
Studies show that taking berberine can lower blood sugar levels to a similar extent as the popular diabetes drug metformin ( 4 ). In a study in 116 people with type 2 diabetes, the substance reduced fasting blood sugar levels by 20% and HbA1c (a marker for long-term blood sugar levels) by 12% ( 5 ).
Insulin remains the most effective therapy to lower glucose, particularly in comparison to most oral medicines for type 2 (including metformin).
Proven long-term side effects of metformin
Of those discussed above, low vitamin B12 levels is the only proven long-term metformin side effect. But, as mentioned, low vitamin B12 levels can cause other problems, including anemia. That's why it's important to go for all recommended blood tests while taking metformin.
Conclusions: People with diabetes taking metformin were less likely to report back, knee, neck/shoulder and multisite musculoskeletal pain than those not taking metformin. Therefore, when treating these patients, clinicians should be aware that metformin may contribute to fewer reports of musculoskeletal pain.
Should you drink a lot of water when consuming this medicine? Metformin must be consumed with meals to assist lower stomach or bowel side effects that might happen during the initial few weeks of treatment. The tablet or extended-release tablet must be taken whole with a full glass of water.
As already discussed, metformin can result in sleep disturbance, and this might affect normal dream patterns. Nightmares are reported in patients receiving metformin.
Diabetics should avoid fruits with a high GI or eat them in moderation so that their blood sugar levels do not spike abruptly. Pineapple, watermelon, mango, lychee, and banana have a high GI, so these are the worst fruits if you are diabetic.
Side effects
Nausea, vomiting, stomach upset, diarrhea, weakness, or a metallic taste in the mouth may occur. Metformin usually does not cause hypoglycemia; however, low blood sugar may occur if this drug is used with other anti-diabetic drugs.
Metformin does cause side effects in some people, but many of these are mild, and are associated with taking the medicine for the first time. Nausea and gastric distress such as stomach pain, gas, bloating, and diarrhea are somewhat common among people starting up on metformin.
Under certain conditions, too much metformin can cause lactic acidosis. The symptoms of lactic acidosis are severe and quick to appear, and usually occur when other health problems not related to the medicine are present and are very severe, such as a heart attack or kidney failure.
Recent studies have also found that metformin has a positive effect on cardiovascular protection [8,9,10,11,12]. Metformin also lowers risk factors for cardiovascular disease such as blood fats [13,14,15], body weight and blood pressure.
Conclusion: Metformin does not appear to cause or exacerbate liver injury and, indeed, is often beneficial in patients with nonalcoholic fatty liver disease. Nonalcoholic fatty liver frequently presents with transaminase elevations but should not be considered a contraindication to metformin use.
This medicine is not recommended in patients 80 years of age and older who have kidney problems.
Nausea, vomiting, stomach upset, diarrhea, gas, weakness, or a metallic taste in the mouth may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If stomach symptoms return later (after taking the same dose for several days or weeks), tell your doctor right away.
