Codeine is an opiate drug that can be lethal when taken in very high doses, or when mixed with other drugs, including other opioids, benzodiazepines, or alcohol.
Codeine is commonly prescribed to treat pain. Taking it in any way other than prescribed can be a risk of overdose.
According to the U.S. Food and Drug Administration (FDA), the lethal dose of codeine is 0.5 to 1 gram, or 500 to 1000 milligrams (mg).
Determining The Lethal Dose Of Codeine
Codeine can begin to have toxic effects after 240 mg in the average person. Toxicity, also known as overdose or drug poisoning, can be lethal or non-lethal and may have lasting effects on health.
Codeine is prescribed in the following dosage amounts in tablet form:
- 15 mg
- 30 mg

Codeine is listed as an ingredient in several medications, including Tylenol with codeine, and prescription cough syrups.
