Fortamet (Metformin) Extended-Release Tablets: Prices, Strengths, and Package Options

Fortamet is a brand-name oral extended-release tablet containing metformin, a biguanide medicine used for type 2 diabetes. We carry Fortamet tablets in four strengths - 250 mg, 500 mg, 850 mg, and 1,000 mg - and offer several package sizes for each strength. The practical choice is therefore which strength your prescriber has specified and how many tablets to order at once. This guide walks through those options, explains how package size affects unit value, and covers the practical, safety, and ordering details associated with choosing an exact package.

Price and Choice Overview

Every Fortamet order starts with two decisions: strength and quantity. We list 250 mg tablets in packages of 60, 120, and 180, while the 500 mg, 850 mg, and 1,000 mg strengths are available in packages of 90, 180, 270, and 360 tablets. The package comparison should begin only after you have confirmed the prescribed strength; a lower unit price does not make a different strength medically interchangeable.

Because treatment for type 2 diabetes is often ongoing, package quantity can affect both total cost and price per tablet. It can also determine how often you need to reorder and how much medicine you must store. A useful comparison therefore considers the full package price, unit value, prescribed tablet count, expected duration of supply, and expiration date rather than focusing on one figure alone.

Available Packages and Unit Value

Choosing a larger package may lower the price per tablet, but the right quantity still depends on the strength your prescriber has selected and how much medicine you can reasonably use before its expiration date. The comparison below presents the exact package prices, unit values, and relative savings for the 250 mg strength so you can see how quantity affects cost before deciding what to order.

For 250 mg tablets, the available quantities are 60, 120, and 180. This range lets you compare a smaller initial outlay with the potential unit value of a larger package. If your dose may change soon, a smaller quantity may limit the number of tablets left over after a new prescription is issued. If your regimen is stable, a larger package may reduce how often you need to reorder. That decision should be based on your prescribed treatment and expected use, not savings alone.

The 500 mg, 850 mg, and 1,000 mg strengths each come in packages of 90, 180, 270, and 360 tablets. These quantities offer several supply-planning choices, but package size does not determine the daily dose or dosing frequency. To estimate how long a package may last, divide its tablet count by the exact number of tablets your prescription instructs you to take each day. Allow for any planned follow-up at which the dose might be reassessed.

Strength, Form, and Quantity Decisions

Metformin dosing is individualized and may be increased gradually to improve glucose control while limiting gastrointestinal effects. The offered strengths provide different prescribed-dose and package options, but their availability does not establish which dose is appropriate for a particular person. Our current Fortamet choices are:

• 250 mg - available in packages of 60, 120, and 180 tablets.
• 500 mg - available in packages of 90, 180, 270, and 360 tablets.
• 850 mg - available in packages of 90, 180, 270, and 360 tablets.
• 1,000 mg - available in packages of 90, 180, 270, and 360 tablets.

Fortamet is an extended-release product, so its administration differs from that of immediate-release metformin. It is generally taken once daily with the evening meal, although the prescription and product directions supplied for the individual patient should control. The tablets should be swallowed whole rather than crushed, cut, or chewed because damaging an extended-release tablet can alter how the medicine is released.

When choosing a quantity, use the prescribed daily tablet count to estimate the planned supply. Do not combine tablets or substitute one strength for another unless a prescriber or pharmacist has confirmed the change. Two tablets with a lower listed strength may equal the same total number of milligrams as one higher-strength tablet, but that arithmetic alone does not establish that the products, release behavior, or directions are interchangeable.

Fortamet, Generic Metformin, and Other Diabetes Medicines

Fortamet contains metformin, the same active ingredient used in other metformin products, but the formulation matters. Immediate-release and extended-release tablets can have different administration schedules, dose limits, tablet-release systems, and tolerability. A prescription written for a specific extended-release product should not be changed to an immediate-release product solely because the active ingredient has the same name.

If you want to review the active ingredient under its generic name, our metformin page provides additional context. Readers comparing broader treatment approaches may also browse our Diabetes section. DPP-4 inhibitors, SGLT2 inhibitors, sulfonylureas, GLP-1 receptor agonists, and insulin work differently from metformin and may be used instead of or alongside it, depending on glucose targets, kidney and cardiovascular health, tolerability, and a prescriber's treatment plan.

Established Use and Product Role

Metformin is an established oral medicine for improving glycemic control in adults with type 2 diabetes and is frequently used alone or with other glucose-lowering therapy. It lowers blood glucose without directly stimulating insulin release, which helps explain why metformin alone has a relatively low risk of hypoglycemia. It is not a treatment for type 1 diabetes or diabetic ketoacidosis.

Pediatric labeling depends on the formulation. Although certain immediate-release metformin tablets have established use in children age 10 and older, safety and effectiveness have not been established for Fortamet. The pediatric status of an immediate-release tablet should not be applied automatically to this extended-release product.

Medicine is only one part of type 2 diabetes management. Nutrition, physical activity, glucose monitoring, laboratory follow-up, and management of blood pressure and lipids may all remain important. A package decision should fit into that broader care plan rather than being treated as a substitute for follow-up.

How Does Fortamet Work, and How Should It Be Taken?

Metformin lowers blood glucose mainly by reducing glucose production in the liver and improving the body's sensitivity to insulin. It also has effects on glucose handling in the intestine. It does not stimulate pancreatic insulin release, so hypoglycemia is uncommon when it is used alone. Low blood sugar becomes more likely when metformin is combined with insulin or an insulin secretagogue such as a sulfonylurea.

Fortamet is generally taken once daily with the evening meal. Taking it with food can help reduce nausea, diarrhea, abdominal discomfort, and other gastrointestinal effects that are common when metformin is started or its dose is increased. Improvements in glucose readings develop with regular use over days, while the full effect of a dose adjustment is assessed through ongoing glucose measurements and follow-up rather than the response to a single tablet.

Take only the prescribed dose, and swallow each extended-release tablet whole. If a dose is missed, follow the instructions from your prescriber or pharmacist rather than doubling the next dose. A tablet-like soft mass may occasionally appear in the stool after the medicine has been released; this can be associated with the extended-release delivery system and does not necessarily mean the dose was not absorbed. Ask a pharmacist or prescriber if this occurs repeatedly or if glucose control changes.

Storage and Practical Handling

• Store Fortamet tablets at 68°F to 77°F, with brief excursions between 59°F and 86°F permitted.
• Keep the container tightly closed and protect the tablets from moisture.
• Leave tablets in their appropriate container and keep them out of reach of children and pets.
• Check the expiration date printed on the package, and choose a quantity you expect to use before that date.
• Match the ordered quantity to the prescribed daily tablet count so the supply aligns with planned follow-up and reordering.

What Safety Considerations Should You Know Before Ordering?

Metformin carries a boxed warning for lactic acidosis, a rare but serious medical emergency. Important risk factors include kidney impairment, age 65 or older, certain contrast-imaging procedures, surgery or restricted food and fluid intake, hypoxic states such as acute heart failure, excessive alcohol intake, liver impairment, and use of certain interacting medicines. Symptoms can include severe weakness, unusual muscle pain, trouble breathing, increasing sleepiness, abdominal discomfort, dizziness, or feeling cold. Urgent medical assessment is required if lactic acidosis is suspected.

Kidney function should be assessed before treatment and at least annually, or more often when the risk of renal impairment is higher. Metformin is contraindicated when eGFR is below 30 mL/min/1.73 m². Starting treatment is generally not recommended when eGFR is between 30 and 45 mL/min/1.73 m², and an existing regimen requires reassessment if kidney function declines.

Long-term metformin use can reduce vitamin B12 levels. Periodic blood counts and vitamin B12 monitoring may be appropriate, particularly when anemia, numbness, tingling, weakness, or other symptoms of deficiency develop. Blood glucose and HbA1c are also monitored to assess effectiveness and guide dose or treatment changes.

• Pregnancy: available human data are limited, while poorly controlled diabetes itself poses maternal and fetal risks. Continuing metformin or using another regimen is an individualized prescriber decision.
• Breastfeeding: metformin is present in human milk. Its benefits, the mother's clinical need, and possible infant effects should be reviewed with a clinician.
• Children: safety and effectiveness have not been established for Fortamet, even though some immediate-release metformin products have pediatric indications.
• Driving: metformin alone rarely causes hypoglycemia, but combining it with insulin or an insulin secretagogue can cause low blood sugar and impair alertness.
• Allergies: Fortamet must not be used by someone with known hypersensitivity to metformin or any component of the tablet.

Iodinated contrast used for some imaging procedures may require metformin to be stopped temporarily in patients with specified kidney-function or other risk factors. Kidney function is generally reevaluated after the procedure before treatment is restarted. Carbonic anhydrase inhibitors, including topiramate, may increase the risk of acidosis. Medicines that reduce metformin clearance, drugs that affect kidney function, and heavy alcohol use can also increase risk. Insulin and sulfonylureas may require dose review because of hypoglycemia. Provide a prescriber or pharmacist with a complete list of prescription medicines, over-the-counter products, and supplements.

Do You Need a Prescription to Order Fortamet in the US?

Metformin is authorized for human medicinal use in the United States, and Fortamet tablets are classified as prescription-only medicine under US regulation. That classification describes the medicine's legal status. Our product-specific requirement for accepting an order is not stated in the available ordering information, so contact our support team before ordering to confirm what documentation our ordering policy requires.

Our pharmacist-supported team is available 24/7 by email, online chat, and phone. We can help clarify the strength and package options shown on the page and explain our ordering process. Questions about whether Fortamet is clinically suitable, what dose to use, or whether another formulation should replace it require review by the prescribing clinician.

Ordering, Delivery, and Receiving Your Order

At checkout, review the exact strength and package quantity selected from the available options. A 250 mg package has different quantity choices from the other offered strengths, so checking both fields helps prevent an avoidable selection error. After we accept an order under our ordering policy, our team prepares and dispatches it for delivery.

• Confirm the product name, extended-release form, strength, and package quantity before finalizing the order.
• Use an accurate delivery address and ZIP code so the order can be routed correctly.
• Contact us by email, online chat, or phone if the displayed option does not match the prescription.
• A pharmacist is available to answer product and order-related questions.
• Orders are packed and dispatched by our team for delivery to the address provided.

When the package arrives, verify the label, tablet strength, quantity, and expiration date before use. Keep the medicine in suitable storage conditions and contact our support team promptly if the delivered package does not match the order. If you reorder regularly, track the number of tablets remaining and allow time for order processing and delivery so you do not run out between shipments.

Value-Based Decision Summary

Choosing a Fortamet package comes down to matching three things: the extended-release strength your prescriber has specified, a quantity that fits the planned supply and storage timeline, and a package size that provides reasonable unit value without leaving tablets unused after a dose change or expiration. The largest package is not automatically the best choice, particularly during titration or when treatment is due for review.

Use the package comparison above to assess the 60-, 120-, and 180-tablet options for the 250 mg strength. For 500 mg, 850 mg, and 1,000 mg tablets, compare the available quantities of 90, 180, 270, and 360. Confirm the formulation and prescribed strength first, estimate the supply from the daily tablet count, and then compare package value. Our support team can clarify the options and our ordering process before you complete your order.
