Suboxone vs. MS Contin

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Buprenorphine/naloxone (Suboxone, Zubsolv, Bunavail) and morphine (MS Contin, Kadian) are both opioid medications, but they serve different purposes and have distinct characteristics. Buprenorphine/naloxone is a combination medication used to treat opioid dependence, while morphine is primarily used to relieve pain when non-opioid medications are not effective. Buprenorphine/naloxone works by partially activating opioid receptors and blocking the effects of other opioids, which helps manage cravings and withdrawal symptoms. In contrast, morphine fully activates opioid receptors to reduce pain. Buprenorphine/naloxone is available in sublingual and buccal forms, whereas morphine can be taken orally, rectally, or via IV. Both medications carry risks of misuse and dependency, but buprenorphine/naloxone is a Schedule III controlled substance, while morphine is a Schedule II controlled substance, indicating a higher potential for abuse. Additionally, buprenorphine/naloxone is often used in combination with counseling and mental health support to treat opioid use disorder, whereas morphine is typically prescribed for pain management alone.

Summary for Suboxone

Prescription only

Suboxone tablets (buprenorphine / naloxone) are used for the maintenance treatment of opioid use disorder (OUD) in adults. This medication-assisted treatment is given along with counseling and social and emotional support. It contains two active ingredients: buprenorphine is a partial opioid agonist, and naloxone is an opioid antagonist. The tablets are taken sublingually once per day (they're placed under the tongue where they dissolve). The dosage depends on each person's situation. Side effects include headache, pain, and nausea. It's a controlled substance because it has a risk of being addictive and being misused.

Note: The Suboxone brand name for the sublingual tablets is discontinued, but there are generic versions available. Buprenorphine/naloxone sublingual tablets are also available under the brand name Zubsolv.
