What you’ll learn
If you missed a dose of Suboxone®, or you’re worried you might, we’ll explain what actually happens in your body when you miss a dose, whether it’s ever okay to take an extra dose to catch up, and exactly how to get back on your normal schedule.
You missed a dose, and now you’re wondering what happens next. First things first: take a breath. This happens to plenty of people who take Suboxone® strips, and there’s a clear way to get back on track without derailing your recovery.
What actually happens when you miss a dose
Suboxone stays in your body a long time, so one missed dose usually won’t throw everything off. The medication’s active ingredient, buprenorphine, leaves the body slowly. It has an average elimination half-life of 24 to 42 hours, meaning your body needs that long to clear out about half of one dose.
That’s why a modest amount of buprenorphine is often still in your system a full day or two after you take it, sometimes longer, depending on your dose, metabolism, and how long you’ve been on treatment. Those same factors determine how long Suboxone stays in your system overall, including how long it can show up on a drug test.
How soon could you feel Suboxone withdrawal symptoms?
Catching a single missed dose the same day usually won’t cause any withdrawal symptoms. If it’s been longer than that, some people notice restlessness, sweating, anxiety, or a return of cravings, roughly a day to two days after the missed dose.
Even if you don’t notice anything, it’s always worth telling your QuickMD doctor that you missed a dose at your next visit. It helps us keep your plan on track and catch a pattern early if this turns out to be more than a one-time thing.
If it’s been longer than a day or two, withdrawal can move through a few distinct stages, each with its own rough timeline.
Should you take an extra dose of Suboxone to catch up?
No. You should never take an extra dose of Suboxone to make up for one you missed. Taking two doses close together raises your risk of excessive sedation. The risk gets even more serious if you add alcohol or other sedating substances, since the combination can dangerously slow your breathing.
There’s a second, less obvious risk. If you missed your dose more than a day ago and used another opioid to get through the discomfort, taking your next Suboxone dose too soon afterward can trigger precipitated withdrawal, a sudden, severe withdrawal reaction.
This happens because buprenorphine attaches very strongly to the same spots in the brain and body that opioids act on and can displace an opioid that’s already there. That’s why treatment has to be timed carefully, and why doctors wait for clear signs of withdrawal before starting or restarting Suboxone at all.
How to safely get back on schedule
If you miss a single dose, take your next dose at your regular scheduled time. There’s no need to make up the missed dose or take extra medication.
If you’ve missed several days but haven’t returned to opioid use, you can generally restart your regular dose. If you’re experiencing withdrawal, your regular dose will likely help relieve those symptoms. If you haven’t experienced significant withdrawal after several days without Suboxone, continue your regular dose and talk with your QuickMD doctor at your next appointment. You may be able to lower your dose.
If you returned to opioid use while you were without Suboxone, restarting is different. You’ll generally need to wait until you’re experiencing at least moderate opioid withdrawal before taking Suboxone again. Book a visit with your doctor if you need help determining when or how to restart.
In any of these situations, let your doctor know what happened at your next appointment. They can determine whether your Suboxone dose should stay the same or be adjusted.
When to book an appointment or contact support
You don’t need to contact our Support Team every time you miss a dose. In many cases, you can simply get back on your regular medication schedule and discuss what happened with your QuickMD doctor at your next appointment.
You should book a visit with your QuickMD doctor if:
- You’re experiencing withdrawal symptoms and have concerns about restarting your medication
- You returned to opioid or other substance use while you were without Suboxone
- You used another substance to manage withdrawal or get through the gap
- You have questions or concerns about whether your dose needs to change
If you’re feeling unsure about what to do, contact our Support Team. They can help point you toward the right next step.
Building a routine so it doesn’t happen again
Taking your Suboxone consistently can help you stay on track with treatment. A few simple habits can make it easier to remember your dose:
- Set a daily alarm for your dose time
- Pair it with something you already do every day, like brushing your teeth or making coffee
- Plan ahead to make sure you have your medication with you when you travel
Frequently asked questions about missed Suboxone doses
What if I run out of Suboxone and cannot get a refill right away?
If you’re running low on Suboxone because your medication was lost or you’ve taken more than prescribed, book an appointment with a QuickMD doctor as soon as you can. Your doctor can talk through what happened and help determine the next step, including whether another prescription is appropriate. You can also read how to get an emergency Suboxone refill to learn more.
Can I take my next dose a few hours early instead of waiting for a missed one?
Generally, yes. Taking a dose a few hours early is different from skipping one and doubling up later, and it doesn’t carry the same risk. Sticking close to your regular schedule is still best, so talk to your QuickMD doctor if you find yourself adjusting the timing often.
Does missing doses make it more dangerous if I go back to using?
Missing one dose isn’t the same as stopping treatment. The risk increases when treatment is stopped or opioid use resumes. One study found that about 5% of people treated with buprenorphine for 6 to 18 months experienced an opioid overdose requiring medical care within 6 months of stopping. Another found that staying in treatment longer was linked to a lower risk of overdose.
Will a missed dose show up on a drug test?
A standard test looking for buprenorphine or naloxone specifically would still likely detect it, since both stay in your system well past a single missed day. A missed dose on its own doesn’t change what a drug test shows for these two medications.
