Overview
Codeine is used to manage mild to moderate pain , where treatment with an opioid is appropriate, and when other pain treatments such as non-opioid pain medicines do not treat your pain well enough or you cannot tolerate them. Codeine is an opioid and considered a strong prescription pain medicine . It also has cough-suppressing (anti-tussive) properties. Codeine is available as one of 2 salts: codeine or codeine phosphate: Codeine phosphate is highly water-soluble and used in oral liquids, tablets, and injections Codeine sulfate is less soluble and primarily used in tablet form Codeine sulfate tablets are the only single-ingredient codeine still available in the United States . An opioid pain medicine that can put you at risk for overdose and death . Even if you take your dose correctly as prescribed, you are at risk for opioid addiction, abuse, and misuse that can lead to death. Codeine is available in combination with several other ingredients, including acetaminophen , guaifenesin , promethazine , and pseudoephedrine. In products containing guaifenesin, promethazine, or pseudoephedrine, codeine is included specifically for its cough-suppressing properties. Codeine falls under three different Schedule classifications depending on the product and how much codeine it contains. Single-ingredient codeine sulfate tablets are Schedule II . Combination products that contain less than 90 mg of codeine per dosage unit (such as acetaminophen with codeine ) are Schedule III Combination cough preparations containing not more than 200 milligrams of codeine per 100 milliliters, such as codeine and guaifenesin , are Schedule V (although some states have reclassified these as Schedule III ). Codeine has been used for over 100 years and has been classified as generally recognized as safe (GRAS) since 1950. On July 16, 2009, single-ingredient, prescription-only codeine tablets received FDA approval via a new drug application (NDA).
