Usage
Metformin is available in different forms, including liquid, regular tablets, and extended-release (long-acting) tablets, all designed for oral administration. The liquid form is typically taken once or twice a day alongside meals. Regular tablets are usually taken two to three times daily with meals, while extended-release tablets are taken once a day during the evening meal.
To ensure consistent and effective use of metformin, it's essential to take it at approximately the same time each day. It's crucial to adhere to the instructions on your prescription label meticulously. If there are any aspects of the directions that you find unclear, do not hesitate to seek clarification from your doctor or pharmacist.
Metformin should be taken precisely as prescribed by your healthcare provider. It's vital not to deviate from the prescribed dosage by taking more or less of the medication or increasing the frequency of administration. When consuming metformin extended-release tablets, they should be swallowed whole without breaking, chewing, or crushing them.
Your doctor may initiate your treatment with a low metformin dose, gradually increasing it, typically not more frequently than once every 1 to 2 weeks. Close monitoring of your blood sugar levels is necessary to assess the effectiveness of metformin in managing your diabetes.
It's important to recognize that metformin helps control diabetes but does not offer a cure. Therefore, even if you are feeling well, it is essential to continue taking metformin as prescribed. Do not discontinue the medication without consulting your doctor, as they will guide the best course of action.
If you require additional information about metformin, you can request the manufacturer's patient information sheet from your pharmacist or doctor.

| Important Warning |
Important Warning
Metformin may, although rarely, lead to a severe and life-threatening condition known as lactic acidosis. It is crucial to inform your doctor if you have kidney disease, as they may advise against the use of metformin in such cases. Additionally, share with your doctor if you are over 65 years old and have a history of a heart attack, stroke, diabetic ketoacidosis (a condition characterized by dangerously high blood sugar levels requiring emergency medical treatment), coma, or heart or liver disease. The concurrent use of specific medications with metformin may heighten the risk of lactic acidosis. It's essential to notify your doctor if you are taking medications such as acetazolamide (Diamox), dichlorphenamide (Keveyis), methazolamide, topiramate (Topamax, part of Qsymia), or zonisamide (Zonegran).
Moreover, if you have recently experienced or developed certain conditions during treatment, inform your doctor promptly. These conditions include severe infections, intense diarrhea, vomiting, fever, or significantly reduced fluid intake for any reason. Your doctor may recommend discontinuing metformin until your recovery is complete.
Should you require surgery, including dental procedures or significant medical interventions, communicate to the healthcare provider that you are currently taking metformin. Additionally, mention if you are planning to undergo an x-ray procedure involving the injection of contrast dye, especially if you have a history of alcohol consumption, including binge drinking, or liver disease, or heart failure. In some cases, it may be necessary to pause metformin before the procedure and wait for 48 hours before resuming treatment. Your doctor will provide precise instructions regarding when to discontinue and restart metformin.
If you experience any of the following symptoms, cease taking metformin and promptly contact your doctor: extreme fatigue, weakness, or discomfort; nausea; vomiting; abdominal pain; reduced appetite; rapid and deep breathing or shortness of breath; dizziness; lightheadedness; rapid or slow heartbeat; skin flushing; muscle pain; or a sensation of coldness, particularly in your hands or feet.
Furthermore, if you consume alcohol regularly or engage in occasional binge drinking, discuss this with your doctor. Alcohol consumption can heighten the risk of lactic acidosis and potentially lead to fluctuations in blood sugar levels. Seek your doctor's guidance on the safe amount of alcohol to consume while taking metformin.
Lastly, make sure to attend all scheduled appointments with your doctor and for laboratory tests. These assessments are essential for monitoring your kidney function and how your body responds to metformin. It's essential to have a conversation with your doctor about the potential risks associated with metformin therapy.
