Lactic acidosis is a dangerous, potentially fatal disease that metformin may occasionally cause. In case you have kidney illness, let your doctor know. Most likely, your doctor will advise against taking metformin. Additionally, let your doctor know if you are over 65 years old, have ever experienced a heart attack, stroke, diabetic ketoacidosis (a condition in which the blood sugar level is so high that it requires immediate medical attention), a coma, or liver or heart illness. Lactic acidosis risk may be raised while taking metformin along with specific other drugs. Inform your physician if you are taking any of the following medications: acetazolamide (Diamox), dichlorphenamide (Keveyis), methazolamide, topiramate (Topamax, in Qsymia), or zonisamide (Zonegran).

If you have recently experienced any of the following issues, or if you develop them while receiving medication, let your doctor know: a major infection; extreme diarrhoea, vomiting, or fever; or if you are drinking much less fluid than normal for any reason. Metformin usage may need to be suspended until your recovery.

Inform the surgeon that you are taking metformin before having any type of major surgery, including dental surgery. Additionally, inform your doctor if you want to undergo any x-ray technique involving the injection of dye, particularly if you currently or previously consume substantial amounts of alcohol, have liver disease, or are currently experiencing heart failure. Before the procedure, you might need to stop taking metformin and wait 48 hours before starting it again. When you should stop taking metformin and when you should resume taking it, your doctor will specify.

Call your doctor right away and stop taking metformin if you have any of the following signs: excessive fatigue, weakness, or discomfort; nausea; vomiting; stomach pain; loss of appetite; rapid, deep breathing; fainting; fast or slow heartbeat; flushing of the skin; pain in the muscles; or feeling cold, particularly in the hands or feet.

If you frequently consume substantial amounts of alcohol in a short period of time or occasionally do so, let your doctor know (binge drinking). Alcohol consumption raises your risk of lactic acidosis and may lower blood sugar levels. How much alcohol is safe to consume while taking metformin should be discussed with your doctor.

Keep all of your appointments with your physician and the lab. In order to monitor your kidney function and how your body is responding to metformin, your doctor will prescribe a number of tests both before and throughout therapy. Discuss the potential risks of taking metformin with your doctor.

Type 2 diabetes is treated with metformin alone or in combination with other drugs, such as insulin (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Metformin belongs to the biguanide drug class. The level of glucose (sugar) in your blood can be managed with the aid of metformin. Both the quantity of glucose your liver produces and the amount you absorb from food are reduced. Metformin also improves the way your body reacts to insulin, a hormone that naturally regulates blood sugar levels.Type 1 diabetes is not treated with metformin (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood).

People with diabetes and high blood sugar over time may experience serious or fatal complications, such as heart disease, stroke, kidney issues, nerve damage, and vision issues. It may be possible to control your diabetes and enhance your health by taking medication(s), making lifestyle changes (such as diet, exercise, and quitting smoking), and monitoring your blood sugar frequently. This treatment may also lower your risk of heart attack, stroke, kidney failure, nerve damage (resulting in numb, cold legs or feet and diminished sex capacity in both men and women), eye issues, such as changes in eyesight or blindness, or gum disease, which are all symptoms of diabetes. The optimal strategy to manage your diabetes will be discussed with you by your doctor and other healthcare professionals.

The oral forms of metformin include liquid, tablet, and extended-release (long-acting) tablet. One or two times each day, the drink is typically consumed with meals. Two or three times a day, the standard tablet is typically taken with meals. The extended-release tablet is often taken with dinner once a day. Take metformin at roughly the same time(s) each day to make it easier for you to remember to take it. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the metformin directions exactly. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not split, chew, or crush the extended-release metformin tablets; instead, swallow them whole.

Your doctor might prescribe you a modest dose of metformin to start, and then gradually raise it once every 1-2 weeks or so. To determine how effectively metformin is working, your doctor will need to closely monitor your blood sugar levels.

Diabetes is not cured by metformin, although it can be managed. Even if you feel good, keep taking metformin. Without consulting your doctor, do not discontinue taking metformin.
