Buckley's cough syrup can be found at Rite-Aid and Eckerd pharmacies, according to the company's website. It is also available from many online retailers, such as Amazon. Buckley's cough syrup is an over-the-counter remedy that is popular in Canada, and it is also available in select stores in the United States.
Many of Buckley's products contain acetaminophen. This is the same medication found in Tylenol and Children's Tylenol. Acetaminophen is used to treat pain and fever, but it is dangerous when taken in high doses, especially for children. In some cases, acetaminophen poisoning causes liver failure, coma or death. For this reason, it is important to avoid mixing multiple medications that contain acetaminophen.
