Product contextClinical information,
Clinical information,
with clear sources.
The treating clinician determines suitability and prescribing. Product-specific labeling and pharmacy guidance remain essential.
Metformin extended-release labeling describes use alongside diet and exercise to improve blood sugar control in adults with type 2 diabetes. Its inclusion in this catalog does not establish a weight-loss indication. DailyMed: metformin ER labeling
Review kidney function and product-specific precautions.
Metformin carries a serious lactic-acidosis warning. The clinician should review kidney function, other medicines, alcohol use and planned contrast imaging or procedures. Vitamin B12 monitoring may also be relevant. MedlinePlus: metformin precautions
ER identifies an extended-release preparation. Confirm the exact product and administration instructions with the pharmacist; do not infer substitution or handling instructions from the strength alone.

Useful answers
Metformin ordering FAQs.
What your team needs to know about access, product options and ordering.
Contact & supportWhich metformin product is listed?
The supplied catalog contains one entry: Metformin HCl ER Tablet 500 mg, listed by Optimal. Confirm the exact manufacturer, current product and labeling with the pharmacy.
What does ER mean?
ER means extended release. Review the exact formulation and product-specific instructions with the pharmacy; the strength alone does not establish interchangeability with another preparation.
Is the listed strength a dosing recommendation?
No. The 500 mg value identifies the listed tablet strength. The treating clinician determines whether metformin is appropriate and what prescription is required.
Does this page present metformin as an approved weight-loss medicine?
No. The catalog places this listing in Medical Weight Management. Metformin ER labeling describes blood sugar control in type 2 diabetes; catalog placement does not establish a weight-loss indication.
Is package quantity specified?
The source listing does not provide a package quantity. Review the exact quantity, manufacturer and dispensing details in your approved account or with the responsible pharmacy.
Can my clinic review pricing online?
Approved clinic accounts can review current products, pharmacy information and account pricing. New practices can request clinic access to begin account review.
Can patients buy directly from this page?
Pricing and ordering are restricted to verified, approved clinic accounts. Patients should contact their treating clinician about prescriptions and treatment.
What should my team check before reordering?
Review the current ER preparation, strength, manufacturer, package quantity, pharmacy availability and prescription requirements. Previous purchases do not replace review of the current product.
