Table of Contents
What is Metformin?
- Metformin is an FDA-approved oral medication for managing Type 2 Diabetes.
- It is also commonly prescribed off-label for other uses, including:
- Diabetes prevention
- Polycystic ovarian syndrome
- Weight loss
How does it work?
- Metformin works in a few different ways:
- It reduces the amount of glucose your liver makes.
- It improves your insulin sensitivity.
- It decreases the amount of sugar (glucose) your body absorbs.
- Metformin can also increase the availability of satiety hormones. This can reduce appetite and cravings, resulting in modest weight loss.
How to use
- Metformin is a tablet that is taken by mouth. It is recommended to take Metformin with or right after a meal to minimize side effects.
Dosing
- Metformin is available in immediate-release and extended-release tablets. The typical starting dose is 500 mg.
- Your doctor will customize dosing based on various factors and will likely increase your dose over time.
If you miss a dose
- Skip the missed dose and take your next dose as scheduled unless your doctor says otherwise.
- Do not take two doses at the same time or extra doses.
Important Safety Information
Risks
- Metformin is considered a relatively safe drug. However, you should not take Metformin if:
- You have severe kidney disease
- You are severely dehydrated
- You are about to undergo surgery
- You just had a CT scan or MRI with intravenous contrast dye
Long-term use of metformin may reduce your body’s ability to absorb vitamin B12.
Side effects
- Common side effects include: nausea/vomiting, diarrhea, excess gas, bloating, abdominal pain, indigestion, and metallic taste. If any of these side effects are persistent, contact your doctor.
- Serious but rare adverse reactions may include: persistent vomiting or abdominal discomfort, worsening of kidney problems, liver injury, or lactic acidosis.
- For women: Metformin shouldn’t be used for weight loss if you are pregnant, planning to become pregnant, or are currently breastfeeding.
What to know about off-label use
- Metformin has been prescribed to you off-label. This means that the drug is not FDA-approved for weight loss, but it is commonly used for weight loss.
- Off-label prescribing is very common and offers the advantages of better pricing, more flexible dosing, and the ability to customize a medication to better fit your needs.
- When using a medication off-label, we may require closer monitoring and more frequent contact so we can monitor side effects or drug interactions.
