How long do I have to be in withdrawal before starting Suboxone?

Buprenorphine/naloxone (Suboxone) should be taken when the body has already started to feel withdrawal symptoms. When taken at the appropriate time,  Buprenorphine/naloxone (Suboxone) should make you feel BETTER (not worse!). 

When you should take Buprenorphine/naloxone (Suboxone) depends on your level of tolerance (how much your body has become “used” to having opioids) and the specific substance and dose you have been taking. 

In general, patients should wait the following number of hours after taking their last opioid before starting their buprenorphine/naloxone (Suboxone) induction:

  • 12-24 hours after their last dose of short-acting opioids (heroin, hydrocodone/Vicodin, oxycodone-immediate release/Percocet, hydromorphone/Dilaudid);
  • 24 hours after their last dose of intermediate-acting opioids (oxycodone-sustained release--Oxycontin or morphine-sustained release--MS Contin);
  • 36 hours after their last dose of methadone
  • 48-72 hours after their last dose of long-acting opioids (Note: since fentanyl’s metabolite, norfentanyl, lasts a long time in the body, it is recommended that patients experience significant withdrawal symptoms before starting Buprenorphine/naloxone (Suboxone))

A good rule of thumb to make sure you experience the appropriate amount of withdrawal before starting Buprenorphine/naloxone (Suboxone) is to make sure you have AT LEAST 3 symptoms of withdrawal AND you feel pretty uncomfortable:

  • Twitching, tremors, or shaking
  • Enlarged pupils
  • Bad chills or sweating
  • Heavy yawning
  • Joint and bone aches
  • Runny nose, tears in your eyes
  • Goose flesh (or goose bumps)
  • Cramps, nausea, vomiting or diarrhea m Anxious or irritable

A final good rule of thumb is to wait until you feel pretty uncomfortable in your withdrawal and THEN wait an additional 1-hour (set an alarm clock!) before taking Buprenorphine/naloxone (Suboxone).

At Bicycle Health, we provide patients with a home-induction handout that will walk you through your withdrawal symptoms so you take Buprenorphine/naloxone (Suboxone) at the appropriate time. We also provide clinical support specialists who are available 24/7 by phone to answer questions and provide support during patients’ home induction.
