- one 500mg tablet with or after breakfast and your evening meal for at least 1 week, then
- one 500mg tablet with or after breakfast, lunch and your evening meal
If you find you cannot tolerate the side effects of standard-release metformin, your doctor may suggest switching to slow-release tablets.
Metformin Use In Childhood And Adolescence
Type 2 diabetes mellitus has dramatically increased in children and adolescents worldwide to the extent that has been labeled an epidemic . Before 1990, it was a rare condition in the pediatric population by 1999, the incidence varied from 8% to 45%, depending on geographic location, and was disproportionally represented among minority groups . There are few studies of metformin use in the pediatric population. Most of them are of short duration and heterogeneous designs.
The beneficial role of metformin in young patients with type 2 diabetes has been demonstrated in a randomized, controlled trial which showed a significant decrease in fasting blood glucose, HbA1c, weight, and total cholesterol. The most frequently reported adverse events were abdominal pain, diarrhea, nausea/vomiting, and headaches. There were no cases of clinical hypoglycemia, lactic acidosis, or clinically significant changes in physical examinations . When compared to glimepiride , metformin lowered HbA1c to < 7%, similar to glimepiride, but was associated with significantly less weight gain. A total of 42.4% and 48.1% of subjects in the glimepiride and metformin groups, respectively, in the intent-to-treat population achieved A1C levels of < 7.0% at week 24 .

Signs Metformin Is Not Working
If your blood sugar is elevated due to a large meal or because of a stressful day, you don’t need to be alarmed. However, if you notice a pattern of high blood sugars it may mean that you need a change in your treatment plan. Elevated blood sugar levels for several days without explanation can be a sign that your metformin is no longer working or that your dose needs to be changed.
Type 2 diabetes is a progressive disease and, in some people, maintenance of blood sugar control with one drug is often possible for only a few years. After that time, you may need additional medicine.
Your blood sugars can also be impacted by:
Perhaps you have been taking metformin for a while but haven’t improved your diet or you stopped exercising. These changes can impact your blood sugar, so it’s important to always work on any behavioral or lifestyle changes that can improve them.

How Does Metformin Help Treat Type 2 Diabetes
Metformin is a prescription medication that is used to treat type 2 diabetes. It helps to control blood sugar by decreasing the amount of sugar that is produced in the liver, increasing the sensitivity of insulin receptors and limiting the amount of sugar that is absorbed by the body from food. It may be combined with other treatments like insulin. This medication is used in conjunction with exercise and diet.

Metformin For Type 1 Diabetes
Metformin is not formally approved for use in type 1 diabetes, but its sometimes prescribed off-label, especially for patients with obesity or overweight, or those that have issues with insulin resistance.
Many doctors have assumed that metformin would enhance glucose control in patients with type 1 for the same reasons that it works in patients with type 2. Clinical evidence, however, has been mixed, with some trials showing good results and others indicating no benefit for glycemic management. The drug may result in modest improvements in LDL-cholesterol, weight, and kidney function.

Metformin In The Management Of Adult Diabetic Patients
Current guidelines from the American Diabetes Association/European Association for the Study of Diabetes and the American Association of Clinical Endocrinologists/American College of Endocrinology recommend early initiation of metformin as a first-line drug for monotherapy and combination therapy for patients with T2DM. This recommendation is based primarily on metformins glucose-lowering effects, relatively low cost, and generally low level of side effects, including the absence of weight gain .
Metformins first-line position was strengthened by the United Kingdom Prospective Diabetes Study observation that the metformin-treated group had risk reductions of 32% for any diabetes-related endpoint, 42% for diabetes-related death , and 36% for all-cause mortality compared with the control group. The UKPDS demonstrated that metformin is as effective as sulfonylurea in controlling blood glucose levels of obese patients with type 2 diabetes mellitus . Metformin has been also been shown to be effective in normal weight patients .
Effects On Thyroid Function
Metformin decreases serum levels of thyrotropin to subnormal levels in hypothyroid patients that use levothyroxin on a regular basis . A significant decrease in TSH without reciprocal changes in any thyroid function parameter in diabetic patients had also been reported but only in hypothyroid subjects, not in euthyroid ones .
The mechanism of the drop in TSH is unclear at this time. Some of the proposed explanations for this effect are enhanced inhibitory modulation of thyroid hormones on central TSH secretion, improved thyroid reserve in patients with hypothyroidism , changes in the affinity or the number of thyroid hormone receptors, increased dopaminergic tone, or induced constituent activation of the TSH receptor .

Managing Metformin Side Effects
Some side effects go away on their own over time. There are a few ways you can ease or avoid problems:
- Ask to start at a low dose. This makes it easier for your body to adjust to the medicine.
- Take metformin with food. Itâs OK to take the medicine on an empty stomach, but having it with a meal makes it easier to handle.
- Ask about the extended-release form of metformin. Youâll take it once a day rather than twice. Because it doesnât release the drug in one burst, side effects are often milder. In one study, just 10% of people who took the extended-release form had diarrhea, compared with 53% of those who took the standard formula. Just 7% had nausea, compared with 26%. And fewer than 1% of those on extended-release metformin had to stop taking it because of side effects.
When Will I See Results
Metformin does not necessarily lead to an overnight improvement in blood sugar levels. It may take a week or two to notice improvement, and several months to experience the peak of action.
Continue to check your blood sugar as prescribed by your healthcare provider and log your results. This way, you can provide your healthcare provider valuable information regarding how your metformin dose is working for you, and they will be much better equipped to adjust your dosage in the future.

How Does Metformin Work For Prediabetes And Insulin Resistance
It is now being reported that many doctors have started to prescribe metformin for prediabetes or those with suspected insulin resistance.
Both conditions, prediabetes and insulin resistance, can be treated with metformin effectively but it is important to treat the cause instead of simply the symptoms. Thats why changing dietary patterns, adopting more physical activity throughout the day, targeting stress levels and treating any hormonal imbalances naturally should be made a priority first.
Should I Expect Immediate Results From Metformin
Results vary from person to person, but will probably take a minimum of a few days to a week to see changes. Most often people will need to gradually increase the dosage over time before they start seeing numbers come down. If you dont see any difference in a month it probably isnt having much of an effect.

Metformin Indications For Management Of Obesity Insulin Resistance And Non
Insulin resistance in obese children and adolescents should be appropriately and aggressively addressed once it is linked to known cardiovascular risks such as IGT, T2DM, dyslipidemia, and hypertension . Non-alcoholic fatty disease, a frequent cause of chronic liver disease in obese adults, is also associated with a higher risk of developing diabetes and of progression to fibrosis and cirrhosis with an increased relative risk of cardiovascular events or death . The true prevalence of NAFLD in children is underestimated. The prevalence of steatosis in obese children was estimated to be 38% in a large retrospective autopsy study .
Currently, the best supported therapy for NAFLD is gradual weight loss through exercise and nutritional support . Metformin is associated with short-term weight loss, improvement of insulin sensitivity, and decreased visceral fat . A reduction in ALT, GGT, and fatty liver incidence and severity has also been described with metformin use .
Metformin may not be as effective as behavioral interventions in reducing BMI and when compared with drugs that are licensed for obesity, its effects are moderate .
