TYLENOL WITH CODEINE #3
Tylenol with Codeine T3s, formally known as Tylenol with Codeine #3, is a commonly prescribed pain killer with the intended use of relieving mild to moderate pain. It is made of acetaminophen, the narcotic pain reliever called codeine, and sometimes caffeine.
Tylenol with Codeine T3s are administered orally, usually as a white, round pill, although liquid forms are also available. The recommended single adult dosage contains about 30 mg of codeine and 300 mg of acetaminophen. Depending on the country that dispenses the drug, caffeine may or may not be included, as there is 15mg in Canadian doses and none in American doses. In Canada, medication containing more than 8mg of codeine must be prescribed by a doctor, while higher codeine containing drugs can be obtained over the counter in the UK.
The way in which T3s affect the body is interesting, as the acetaminophen component of this drug is Tylenol and works as an analgesic/pain killer and antipyretic/fever reducer. Acetaminophen is considered a non-opioid drug that reduces peripheral pain through inhibiting the enzyme cyclooxygenase (COX). Although the exact mechanism is still being studied, it is hypothesized that through this inhibition, there is a reduction of the pain generating substance called prostaglandins. The fever reducing component of acetaminophen works by acting on the hormone regulator in the brain called the hypothalamus. The other component of T3s, codeine, is an opioid agonist and although now produced synthetically, is originally derived from the naturally occurring opium poppy plant. In the liver, codeine is partially converted into morphine, which blocks opioid pain receptors in the spinal cord and brain. Codeine is also commonly used as a cough suppressant.
