Advil is a brand of ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation. According to Drug Patent Watch [1], the patent for Advil expired in 2001, which means that there are now many generic versions of ibuprofen available at a lower cost. However, Advil still offers coupons and discounts on their website [2], which can help to reduce the cost of their brand-name product.

GoodRx [3] is a website that compares prices for prescription drugs at different pharmacies. According to their website, the average retail price for 90 tablets of 200mg ibuprofen is around $8. However, with a GoodRx coupon, the price can be reduced to as low as $4 at some pharmacies. It is important to note that the price of ibuprofen can vary depending on the dosage, quantity, and location.

In conclusion, the amount that can be saved with Advil coupons depends on the specific coupon and the price of ibuprofen at the pharmacy. However, it is important to consider that there are many generic versions of ibuprofen available at a lower cost than the brand-name product. Consumers can use websites like GoodRx to compare prices and find the best deal for their needs.
