Metformin is a prescription drug used in treating type-2 diabetes by reducing blood glucose (sugar) levels. It belongs to a class of drugs known as biguanides and works by reducing glucose production in the liver and increasing insulin sensitivity in the body. Metformin is based on the active pharmaceutical ingredient (API) – metformin hydrochloride, which is commonly used in its salt form. Metformin is available in the form of extended-release tablets, immediate-release tablets and oral solution. It is often prescribed as a first-line treatment for type 2 diabetes, where diet and lifestyle changes do not have a significant impact.
Diabetes worsens over time, but taking care of your lifestyle can help you avoid taking more medication. A study by the National Institutes of Health revealed that patients in the lifestyle intervention group who followed a low-calorie, low-fat diet combined with 150 minutes of moderate-intensity exercise per week saw a 67% reduction in their risk of developing type 2 diabetes.

Therefore, it is important to consult a healthcare provider who can determine the appropriate Metformin
dosage for diabetes as per the patient’s needs.

Metformin 1000 mg or any other dosage of the drug can interact with certain medications and substances, which can increase the risk of side effects. Here are some of the interactions of metformin:
NIH research suggests that excessive alcohol consumption may contribute to the development of lactic acidosis and hypoglycemia when combined with metformin, a rare but serious side effect of the medication.
Taking metformin with other diabetes medications that lower blood sugar, such as insulin or sulfonylureas, can increase the risk of hypoglycemia (low blood sugar).
As mentioned earlier, metformin can interfere with imaging tests that use contrast dye. It is generally recommended to stop taking metformin before these tests and wait for 48 hours before resuming the medication.
Some blood pressure medications, such as ACE inhibitors and angiotensin receptor blockers (ARBs), can decrease the effectiveness of metformin.
Vitamin B12 supplements can help prevent vitamin B12 deficiency caused by metformin, but they can also decrease the effectiveness of the medication.
Some antibiotics, such as ciprofloxacin, can increase the risk of hypoglycemia when taken with metformin. Also, consuming Metformin along with Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, combiflam and naproxen, can increase the risk of lactic acidosis.
It is important to tell your healthcare provider about all the medications and supplements you are taking
before starting metformin or any other medication.

Although generally safe and effective, certain individuals should refrain from taking metformin. Those with serious kidney or liver conditions may struggle to process the medication, leading to an increased risk of toxicity.

A healthcare provider will recommend the most suitable alternative to metformin based on factors like a patient's health status, blood sugar control, and any existing medical conditions.
Metformin is a medication that is often recommended as the preferred treatment for type-2 diabetes due to its many benefits. Metformin primarily functions by reducing the blood sugar levels, which is done by limiting the glucose released by the liver. Additionally, it improves the body's ability to utilize insulin, further assisting in the regulation of blood sugar levels.
Unlike other medications used to treat diabetes, Metformin is less likely to cause low blood sugar and may even help with weight loss. Studies have also shown that Metformin can help reduce the risk of heart disease and overall mortality in people with type-2 diabetes. Moreover, Metformin is an inexpensive medication that can be used safely as the first-line treatment for type-2 diabetes.
It is advised to eat a healthy, balanced diet that contains complex carbs, such as whole grains and vegetables, while limiting simple sugars and processed carbohydrates when using Metformin. This aids in controlling blood sugar levels and avoiding glucose spikes. Furthermore, it’s highly recommended to avoid excessive alcohol consumption, which when combined with Metformin raises the risk of lactic acidosis. To ensure that their diabetes is managed as effectively as possible, patients should talk to their healthcare professional about their dietary requirements and limits.
If you missed your dose of Metformin, immediately take it when you recall. However, if it's almost time for the next dose, you can take it and skip the missed one.
