Buprenorphine-naloxone

Opioids and strong painkillers

Also known as Suboxone

This is medication for opioid use disorder — real, evidence-based treatment, not "replacing one addiction with another." The buprenorphine eases cravings and withdrawal by partly activating the same receptors opioids do, but with a built-in ceiling that makes dangerous slowed breathing much less likely; the naloxone is there to discourage misuse. Taken daily, it lets your brain and your life stabilize, and it dramatically lowers the risk of overdose death. Staying on it as long as it helps is a success, not a failure.

How to take it

When

Usually once a day, exactly as your prescriber directs. One critical rule at the start: beginning it too soon after other opioids triggers sudden, intense withdrawal — follow your start-up instructions to the letter, including how long to wait.

How to take it

Place the film or tablet under your tongue and let it dissolve completely — don't chew it, don't swallow it whole, and don't eat, drink, or smoke while it's dissolving, or you'll lose much of the dose.

Avoid

Don't mix with alcohol, benzodiazepines (like Xanax or Klonopin), or other sedatives — that combination can still slow your breathing dangerously, even with buprenorphine's safety ceiling. Don't drive until you know how it affects you. And don't stop taking it without your prescriber — stopping raises your overdose risk sharply.

Keep it safe

Lock it away from children — a single dose can be fatal to a child. Never share it, and return leftovers to a pharmacy take-back. It's still smart to keep naloxone (Narcan) at home; it's available without a prescription. If you're pregnant, don't stop on your own — talk to your doctor, because treatment during pregnancy is usually safer than stopping.

Missed a dose?

If you miss a dose, take it as soon as you remember, then get back to your regular schedule. Never take a double dose to catch up.

Common side effects

Headache
Constipation — stay ahead of it with fluids and fiber, and ask about a stool softener
Sweating
Trouble sleeping
Numbness, tingling, or redness in your mouth where it dissolves

Call a doctor if

Very slow or shallow breathing, extreme drowsiness, or someone who can't be woken — especially if alcohol or sedatives are involved — give naloxone if available and call 911 immediately
A child has taken any amount — call 911 right away; even one dose can be fatal to a child
Yellowing skin or eyes, dark urine, or pain in your upper right belly — possible liver trouble; call your doctor now
Hives or swelling of your face, lips, or throat — call 911 if breathing is affected
Fainting, severe dizziness, or a pounding, irregular heartbeat — get medical help
