Final answer:
Tylenol #3 contains 30 milligrams of codeine per tablet, along with 300 milligrams of acetaminophen. Codeine can be used for minor pain relief but has potential for abuse and serious side effects.
Step-by-step explanation:
The amount of codeine found in Tylenol #3 is typically 30 milligrams per tablet. Additionally, each Tylenol #3 tablet contains 300 milligrams of acetaminophen. Codeine is a relatively low potency opioid that is often prescribed for minor pain. It's available over-the-counter in some countries, but like all opioids, it has potential for abuse. Adverse effects of codeine, especially in children, include breathing problems and other serious side effects which led to an FDA warning in 2015. For pain relief, opioids like oxycodone and hydrocodone are used for more severe pain.
