It's best to take metformin tablets with, or just after, your evening meal to reduce the chance of getting side effects. Swallow your metformin tablets whole with a drink of water. Do not chew them. If you're taking metformin sachets, pour the powder into a glass and add water (about 150ml).
Metformin should be taken with meals to help reduce stomach or bowel side effects that may occur during the first few weeks of treatment. Swallow the tablet or extended-release tablet whole with a full glass of water. Do not crush, break, or chew it.
As much as possible, avoid white bread, white rice, white pasta, candy, soda, desserts, and snacks like chips or crackers. Eating foods that can spike your blood sugar will not necessarily make the metformin not work, however, it will increase the burden it has to work against.
It could be that you are not following dietary guidelines, have stopped exercising, or have gained excessive weight. Or, it could be that you're not taking the drug as prescribed. Whatever the reason, the very first indication that metformin is not working is when your blood glucose levels are high.
Extended-release metformin is taken once a day and should be taken at night, with dinner.
The average weight loss in the group that received metformin was 5.8 kg (12.8 lbs) ±7 kg (± 15 lbs). Untreated controls gained 0.8 kg (1.8 lbs) ± 3.5 kg (± 7.7 lbs) on average. Patients with severe insulin resistance lost significantly more weight as compared to insulin sensitive patients.
It's best to avoid saturated fats, excess alcohol consumption, too much sodium, refined carbohydrates, and processed and added sugars while taking it. Aim for a diet full of whole, unprocessed foods including fruits, vegetables, healthy fats, fiber, lean protein, and lower-fat dairy.
When you eat sugar and metformin, your body will have to work harder to lower your blood sugars. Check out ingredient labels to determine how much sugar is lurking in your cereal, pasta, or other food. Talk to your healthcare provider and consider consulting a nutritionist or dietician if you still have diet questions.
Metformin helps lower how much sugar gets absorbed through your intestines, which means that less sugar makes it to your bloodstream.
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%.
Another study, published in May 2020 in the journal Diabetes Care, found that when participants increased their metformin dose by 1,000 mg or more, they lost significantly more weight than those who didn't change their metformin dose or decrease their dose.
Is metformin safe? Recent research has also demonstrated that a low dose of metformin (1000-1500mg/day) can promote weight loss in non-diabetic individuals.
Metformin dosage for weight loss
After titration, the maintenance dose of immediate-release metformin is 2000 mg/day in divided doses. Divided doses should be taken with meals, typically twice per day (for example, with breakfast and dinner). The maximum dose is 2550 mg/day.
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.
The use of metformin by non-diabetics stems from some evidence that metformin can decrease inflammation, protect against cardiovascular disease and cognitive impairment, minimize cancer risk and progression, and prolong life.
Taking metformin can cause vitamin B12 deficiency if you take it for a long time. This can make you feel very tired, breathless and faint, so your doctor may check the vitamin B12 level in your blood. If your vitamin B12 levels become too low, vitamin B12 supplements will help.
Numerous research groups have reported that metformin has beneficial effects on a variety of inflammatory skin disorders including psoriasis, acanthosis nigricans, acne, hidradenitis suppurativa, and allergic contact dermatitis.
Why is metformin called the miracle drug? Metformin has been referred to as a miracle drug due to its relatively low cost, minimal risks, and ability to ward off diabetes and potentially some effects of ageing.
Some simple and refined carbohydrates
Metformin helps limit blood glucose levels. Simple and refined carbs boost those blood sugar levels, which can increase weight gain and cause metformin not to work as well as it should.
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.
Metformin reaches the highest concentration in the blood (peak concentration) 1-3 hours after taking the pill. The half-life of metformin is 2-6 hours. Half-life of a drug is the time it takes for the concentration of a drug to be reduced by 50%. However, the half-life may take up to 14 hours.
