Wondering what Metformin costs? Explore average prices, differences between ER and IR forms, and how Metformin may be included in licensed healthcare provider-guided MedKits on the Eden platform.

Key takeaways
  • Metformin is one of the most affordable prescription medications available, with generic versions costing under $10/month in most U.S. pharmacies.
  • The extended-release version (Metformin ER) may cost slightly more but is often preferred for its tolerability.
  • Metformin ER may be included in MedKits guided by licensed healthcare providers on the Eden platform, with no extra charge for dosage changes or titration over time.
  • Flat-rate pricing on the Eden platform includes a licensed healthcare provider evaluation, prescription fulfillment, and delivery, starting at $150/quarter.

What Affects the Price of Metformin?

Metformin is a generic drug, which means multiple manufacturers may produce it at low cost. That said, price can vary based on:

  • Immediate-release (IR) vs. Extended-release (ER) formulations
  • Dose (500 mg vs. 1000 mg)
  • Quantity (30 vs. 90 tablets)
  • Pharmacy markup or insurance plan contracts

For example:

  • Metformin IR 500 mg (30-day supply): $4–$10
  • Metformin ER 500 mg (30-day supply): $10–$25
  • Metformin ER 1000 mg (30-day supply): $15–$35

Prices may be lower at warehouse pharmacies (like Costco) or through discount cards such as GoodRx, but vary by region.

Why Some People Prefer Metformin ER

Metformin ER is designed to release the active ingredient slowly, which may lead to:

  • Fewer GI side effects for some individuals
  • Once-daily dosing
  • May be better tolerated by individuals new to Metformin

Licensed healthcare providers on the Eden platform may initiate treatment with Metformin ER 500 mg and adjust as clinically appropriate.

Eden’s Pricing: What’s Included

Instead of buying Metformin separately and arranging your own pharmacy, upon eligibility, the Eden platform facilitates access to:

  • Clinical intake + licensed healthcare provider consultation
  • Ongoing access to dosage adjustments
  • Free home delivery
  • Monthly or quarterly refills based on your treatment plan

This includes licensed healthcare provider guidance and medication management with transparent, flat-rate pricing—no insurance billing, and no additional pharmacy service fees beyond what's included in your plan.

Can Insurance Cover It?

Yes—Many insurance plans cover generic Metformin, but it’s not always the most cost-effective option. Some retail pharmacies may offer pricing lower than an insurance copay for those paying cash, especially when brand-name versions aren’t required.

The Eden platform does not work with insurance and does not submit insurance claims. Instead, it operates as a direct-to-consumer, cash-pay service. All costs—including licensed healthcare provider consultations, care plan support, and medication dispensing through partner pharmacies—are bundled into a flat-rate fee.

Some individuals experience fewer gastrointestinal side effects with the extended-release version of Metformin, particularly when starting treatment. Licensed healthcare providers on the Eden platform may recommend Metformin ER based on clinical judgment and a person’s specific needs or tolerability.
