February 2013: An update from the FDA added a “black box warning” to the drug label of codeine and codeine-containing preparations. The warning advises health care professionals “to prescribe an alternative analgesic [to codeine] for postoperative pain control in children undergoing tonsillectomy and/or adenoidectomy.
The enzyme activity for an individual is the sum of activity from each parent’s allele. More than 70 different alleles have been identified, with individuals inheriting 1 allele from each parent. The level of enzyme activity from each allele has been broadly classified according to the following scheme: normal function = 1, reduced function = 0.5, and no function = 0. On the basis of these additive scores, individuals can be classified as extensive (score of 1–2), intermediate (0.5), or poor (0) metabolizers.
Doctors are writing fewer pediatric prescriptions for codeine, following a 2013 warning from the F.D.A. to avoid the drug after tonsil or adenoid surgery. In 2014 The use of tramadol was linked to three deaths and six cases of respiratory troubles in children under 18 between January 1969 and March 2016.
The problem with both codeine and tramadol is that some people are “ultrarapid metabolizers” whose livers metabolize the drugs much too quickly, causing dangerously high levels of opioids to build up, said Dr. Douglas Throckmorton, the deputy director for regulatory programs at the F.D.A.’s Center for Drug Evaluation and Research. No test can identify who might metabolize the drug too quickly, and that is why the agency issued blanket warnings for children by age.
“We can’t forbid prescribers from using their own clinical judgment to prescribe a product to anyone,” said Sarah Peddicord, a spokeswoman for the F.D.A.
Products containing codeine or tramadol will now carry a "Contraindication" for children under the age of 12, which is the FDA's strongest warning. The agency cited In 2016, the American Academy of Pediatrics issued a policy statement that advised against the use of codeine in all children. The agency.
Throckmorton added in a media briefing that there is no way to know which children are “rapid metabolizers,” because it is genetically determined and varies by racial and ethnic group.
There is also a strengthened "Warning" advising against the use of these products among breastfeeding mothers, as it may cause serious harm to their infants. The FDA also added a new "Warning" advising against the use of products with codeine and tramadol in children ages 12 to 18 who are obese or have obstructive sleep apnea or serious lung disease.

October 20, 2016. By Rachael Zimlich, RN. The American Academy of Pediatrics (AAP) is no longer recommending codeine use in children because it can be either Health Organization (WHO) and the FDA have recently issued “stern warnings” about adverse effects stemming from codeine use in children, Tobias says.

On the other end of the spectrum, observations of ultrarapid metabolism were later found in patients of African/Ethiopian, Middle Eastern, and African American heritages. Variation in codeine metabolism was first recognized as a result of poor efficacy, mainly in individuals of northern European Caucasian descent.
Many hospitals have already removed codeine from their formularies for children, and the US Food and Drug Administration (FDA) is slowly moving toward a full ban, proposing a strong recommendation against pediatric use of the medication in late 2015.

Joseph D Tobias, MD, chief of Anesthesiology and Pain Medicine at Nationwide Children’s Hospital, professor of Anesthesiology and Pediatrics at The Ohio State University in Columbus, and lead author of the AAP’s recommendation, says he hopes to alert physicians to the potential dangers—including mortality—related to the genomic variation in codeine metabolism.
Its analgesic effects are produced when the codeine is metabolized by the liver into morphine, but Tobias says there is substantial genetic variability in the hepatic enzyme that guides this process, causing a wide variation in patient response ranging from no effect to high sensitivity.
The FDA issued its strongest level of drug warnings concerning children's usage of the opioid pain-relievers codeine and tramadol.
However, please know that our decision today was made based on the latest evidence and with this goal in mind: keeping our kids safe,” said Dr. Douglas Throckmorton, the FDA’s deputy center director for regulatory programs, in a written statement. “We understand that there are limited options when it comes to treating pain or cough in children, and that these changes may raise some questions for health care providers and parents.
