Check the coupon’s source. Reputable pharmaceutical websites, manufacturer sites like those of Pfizer (or their distributors), or patient assistance programs are reliable sources. Avoid coupons from unknown or suspicious websites.
Examine the coupon’s details carefully. Verify the medication name (Mestinon 180 mg) and dosage are clearly stated. Confirm the expiration date. A valid coupon will have a clear expiration date, not an open-ended timeframe. Note any restrictions on use; some coupons may limit use to specific pharmacies or patients meeting certain criteria.
Look for a unique coupon code or identification number. Legitimate coupons often include a unique alphanumeric code for verification by your pharmacy. Missing this is a red flag.
Contact your pharmacy. Before using any coupon, confirm its validity with your pharmacist. Pharmacies have systems to verify legitimate manufacturer coupons and patient assistance program offers.
Be wary of coupons promising unrealistically low prices or significant discounts. Extremely low prices are often indicative of fraudulent coupons. Use common sense when evaluating the offer.
Report suspicious coupons. If you encounter a coupon you believe to be fraudulent, report it to your pharmacy and the appropriate authorities, such as the state’s board of pharmacy or the Federal Trade Commission.
