Tylenol with Codeine: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions
What Is Tylenol with Codeine?
Tylenol with Codeine is a prescription pain-relief medication that combines acetaminophen (paracetamol) with codeine, an opioid analgesic. The combination is used to treat mild to moderately severe pain when non-opioid pain medicines alone are not effective or appropriate.
Depending on the formulation and country, Tylenol with Codeine may contain different amounts of codeine, including:
- Tylenol with Codeine No. 2 – Acetaminophen 300 mg / Codeine 15 mg
- Tylenol with Codeine No. 3 – Acetaminophen 300 mg / Codeine 30 mg
- Tylenol with Codeine No. 4 – Acetaminophen 300 mg / Codeine 60 mg
The exact formulation available varies by country.
How Tylenol with Codeine Works

Tylenol with Codeine provides pain relief through two different mechanisms:
- Acetaminophen (Paracetamol) helps reduce pain and fever by acting on the central nervous system.
- Codeine is an opioid that is converted by the body into morphine in some individuals, helping reduce the perception of pain.
Together, these ingredients provide greater pain relief than acetaminophen alone for some types of pain.
