Advil is a popular over-the-counter pain reliever medication that contains ibuprofen. According to Drug Patent Watch [1], the patent for Advil expired in 1984, which means that the drug can be produced by other companies as a generic medication. This increased competition can lead to lower prices and more frequent coupons and discounts.

The Advil website [2] offers occasional coupons and offers for their products. As of September 2021, there are currently no coupons available on their website. However, customers can sign up for their newsletter to receive updates on future promotions and coupons.

SingleCare [3] is a prescription savings service that partners with pharmacies to provide discounts on prescription medications, including Advil. The website offers a coupon for Advil that can be used at participating pharmacies. The availability of this coupon may vary, so it is best to check the website periodically for updates.

In conclusion, while there is no set schedule for Advil coupons, they are available occasionally on the Advil website and through prescription savings services like SingleCare. It is best to check these sources periodically for updates on promotions and discounts.
