Based on the information provided, I cannot directly confirm whether cashback rewards apply to Advil purchases with coupons. However, I can provide some context that may help answer this question.

Cashback rewards are typically offered by credit card companies or independent apps and websites that provide a percentage of cashback on eligible purchases. These rewards are usually calculated as a percentage of the purchase price, excluding any discounts, coupons, or other forms of payment [1].

Advil, a well-known brand of ibuprofen, is a product of Pfizer, a major pharmaceutical company. Pfizer's patent for Advil expired in 2005, leading to the availability of generic versions of ibuprofen [2].

DrugPatentWatch.com, a website that tracks drug patents and related information, provides data on drug patents and their expiration dates [3]. However, it does not provide specific information on cashback rewards or coupons for Advil or other drugs.

In conclusion, while cashback rewards are typically not applied to the discounted portion of a purchase, the specific policy may vary depending on the cashback program and the retailer. It is recommended to check the terms and conditions of the specific cashback program and the retailer's policy regarding coupons and discounts.
