Factors Affecting Price
- Pharmacy: Prices vary widely between pharmacies. Compare prices at multiple local pharmacies and online pharmacies. Insurance Coverage: Your insurance plan’s formulary and copay will greatly influence your out-of-pocket cost. Check your plan’s details. Dosage and Quantity: Higher dosages and larger quantities usually mean a higher price, regardless of whether it’s generic or brand-name. Manufacturer: While generics are typically very similar in price, slight variations can exist between manufacturers.
Savings Strategies
Use a prescription discount card: Many cards offer discounts on both generic and brand-name medications. Explore mail-order pharmacies: Mail-order pharmacies often offer lower prices for larger quantities of medication. Ask your doctor about samples: Your doctor might have samples available, especially if you’re starting a new prescription. Consider a 90-day supply: Purchasing a 90-day supply can sometimes reduce the per-pill cost.
Example Price Differences
While exact pricing fluctuates, a 30-day supply of generic metformin ER might cost between $10 and $40, while the brand-name equivalent could cost anywhere from $50 to $150 or more. These are estimates and can vary greatly.
Recommendation
Unless your doctor specifically recommends otherwise, opting for generic metformin ER will almost always result in substantial savings without compromising medication efficacy. Always compare prices and explore available cost-saving options.
