Quick Answer
The two main types of metformin medication are Immediate-Release (IR) and Extended-Release (ER/XR/SR). Metformin usually comes in dosages of 500mg, 850mg, and 1000mg. Tablet sizes vary significantly by manufacturer and strength; the 1000mg pills are the largest, while 500mg pills are the smallest. If you struggle with swallowing large pills, you can ask your pharmacist for specific generic brands that manufacture smaller metformin tablets or inquire about liquid formulations.
What Are the Two Types of Metformin?
When investigating what are the two types of metformin, the medical community distinguishes primarily between the rate at which the active ingredient enters your bloodstream. The different forms of metformin are specifically engineered to cater to different digestive tolerances and dosing schedules.
Immediate-Release (IR) Tablets
This is the standard metformin formulation. It dissolves quickly in the stomach, providing a rapid dose of the medication. Because of this quick absorption, a standard metformin frequency requires it to be typically taken two to three times a day with meals. The rapid release is more likely to cause temporary gastrointestinal side effects.
Extended-Release (ER) Tablets
Also known as XR, SR, or depot versions, types of metformin extended release tablets dissolve slowly over time. This gradual absorption significantly reduces stomach upset. There are actually 3 different formulations of metformin ER depending on the osmotic or polymer matrix used by the generic manufacturer. They are usually taken once a day with the evening meal.
Dosages and Metformin Tablet Size Comparison
A common concern among diabetic patients is pill size. Metformin comes in what dosages? Metformin usually comes as 500mg, 850mg, or 1000mg tablets. The size difference between metformin 500 vs 1000 is highly noticeable; the 1000mg tablets are significantly larger and are often scored down the middle so they can be split easily.
Is all metformin the same size? No. The different numbers on metformin pills indicate the manufacturer, lot, and strength. For example, some brands manufacture smaller metformin tablets by utilizing a more compact powder density, although they deliver the exact same amount of active ingredient. If you are looking for which metformin tablet is the smallest one, certain generic manufacturers produce a more oval-shaped, film-coated 500mg IR pill that is much easier to swallow.
Metformin Tablet Visual Aids
When examining pictures of immediate release and extended release metformin pills side-by-side, the ER tablets generally have a thicker profile due to the polymer matrix required for the slow-release mechanism. The metformin depot versus regular tablet visual distinction is primarily found in this thickness and the specific imprint code etched on the pill’s surface.
FAQ: Frequently Asked Questions
Are there different forms of metformin?
Yes, there are two primary forms: immediate-release (IR) and extended-release (ER). Within these categories, there are various generic manufacturers that produce different tablet shapes, sizes, and liquid oral solutions.

Yes. The 500mg dosage is naturally the smallest. If you have trouble swallowing, you can ask your pharmacist for a specific generic brand that manufactures a more compact pill, or request a liquid formulation.
How do I know what type of metformin I am taking?
