Is codeine sulfate a controlled substance?
Yes. Codeine sulfate is a Schedule II (C-II) controlled substance under federal law, reflecting its opioid abuse and dependence potential.
What is codeine sulfate used for?
Single-entity codeine sulfate is FDA-approved for the management of mild to moderate pain in adults, when an opioid is an appropriate treatment and other options aren't adequate. It is not labeled as a cough treatment on its own.
How long does codeine sulfate stay in your system?
How long codeine sulfate stays in your system varies from person to person, depending on factors like dose, how often it's taken, and individual metabolism and kidney/liver function. Ask your prescriber or pharmacist for guidance specific to your situation.
What is the difference between codeine sulfate and codeine phosphate?
Both are salt forms of the same active opioid, codeine, and the choice between them mainly affects the formulation (for example, solubility) rather than creating a different drug. Codeine sulfate is the salt form used in the tablets and oral solution covered on this page; check your specific prescription label to confirm which salt form you've been prescribed.
Can you take codeine sulfate for a cough?
Single-entity codeine sulfate (the product covered on this page) is FDA-approved for pain, not for cough.

What Is Codeine Sulfate?

Codeine sulfate is an opioid agonist analgesic approved by the FDA for the management of mild to moderate pain in adults, in situations where an opioid is appropriate and other treatment options are not adequate. It's dosed as needed, typically every 4 hours, up to a maximum set by your prescriber. Codeine sulfate was historically combined with acetaminophen in products marketed as Tylenol with Codeine, but the single-ingredient (single-entity) codeine sulfate tablets and oral solution covered on this page are labeled specifically for pain, not for cough.

Codeine Sulfate Cost Without Insurance

Because codeine sulfate is generic-only, there's no manufacturer savings card to check — but that also means pharmacies price it independently, and cash prices can differ a lot by location and by pharmacy chain. As a Schedule II controlled substance, not every pharmacy stocks it in the same quantities, which is another reason prices and availability are worth comparing before you go. Rather than guessing, enter your ZIP code above and Rx.com will show you how nearby pharmacies compare, so you can choose the one that works best for your prescription.

Codeine Sulfate vs. Other Opioid Pain Medications

Codeine sulfate is one of several opioid options a prescriber may consider for pain that doesn't respond well to non-opioid treatment. Depending on the type and severity of pain, a provider might instead consider tramadol, hydrocodone/acetaminophen, oxycodone, or morphine sulfate, or a combination product like acetaminophen with codeine. Every opioid carries its own dosing, interaction, and safety profile, so switching between them is a decision for you and your prescriber, not something to do on your own.

Codeine Sulfate Safety Information

Codeine sulfate carries FDA boxed warnings for the risk of addiction, abuse, and misuse even when taken as prescribed; life-threatening respiratory depression, which is highest when starting the medication or increasing the dose; the danger of accidental ingestion by children; and neonatal opioid withdrawal syndrome if used for a prolonged period during pregnancy. Taking codeine sulfate together with benzodiazepines or other central nervous system depressants can increase the risk of severe or fatal respiratory depression. It is contraindicated in children under 12 and in patients under 18 who have had a tonsillectomy or adenoidectomy, and it is not for use in significant respiratory depression, acute or severe asthma, known or suspected bowel obstruction, or in nursing mothers. These particular restrictions exist because some people are genetically "ultra-rapid metabolizers" who convert codeine to morphine in the body faster and more extensively than usual; in those individuals, even a normal dose of codeine can raise morphine levels to a life-threatening or fatal degree, which is the specific concern behind the pediatric and breastfeeding restrictions. Codeine sulfate is subject to an FDA-required Risk Evaluation and Mitigation Strategy (REMS) for opioid analgesics. This is general information, not medical advice — talk with your prescriber or pharmacist about whether codeine sulfate is right for you.
