if you have serious breathing problems
if you have serious problems with your liver
if you are intoxicated due to alcohol or have trembling, sweating, anxiety, confusion, or hallucinations caused by alcohol.
if you are taking naltrexone or nalmefene for the treatment of alcohol or opioid dependence.
asthma or other breathing problems
problems with your liver such as hepatitis
low blood pressure
recently suffered a head injury or brain disease
a urinary disorder (especially linked to enlarged prostrate in men)
any kidney disease
thyroid problems
adrenocortical disorder (e.g. Addison’s disease)
depression or other conditions that are treated with antidepressants. The use of these medicines together with Suboxone can lead to serotonin syndrome, a potentially life-threatening condition (see ‘’Other medicines and Suboxone’’).
An emergency unit should be contacted immediately in case of accidental ingestion or suspicion of ingestion.
You may be more closely monitored by your doctor if you are over the age of 65.
This medicine can be a target for people who abuse prescription medicines and should be kept
in a safe place to protect it from theft (see section 5). Do not give this medicine to anyone else. It can cause death or otherwise harm them.
Some people have died from respiratory failure (inability to breathe) because they misused buprenorphine or have taken it in combination with other central nervous system depressants, such as alcohol, benzodiazepines (tranquilisers), or other opioids.
This medicine may cause severe, possibly fatal, respiratory depression (reduced ability to breathe) in children and non-dependent people who accidentally or deliberately take it.
Suboxone can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.
This medicine can cause dependence.
This medicine can cause opioid withdrawal symptoms if you take it too soon after taking opioids. You should leave at least 6 hours after you use a short-acting opioid (e.g. morphine, heroin) or at least 24 hours after you use a long-acting opioid such as methadone.
This medicine can also cause withdrawal symptoms if you stop taking it abruptly. See section 3 ‘stopping treatment’.
Liver damage has been reported after taking Suboxone, especially when the medicine is misused. This could also be due to viral infections (e.g. chronic hepatitis C), alcohol abuse, anorexia or use of other medicines with the ability to harm your liver (see section 4). Regular blood tests may be conducted by your doctor to monitor the condition of your liver. Tell your doctor if you have any liver problems before you start treatment with Suboxone.
This medicine may cause your blood pressure to drop suddenly, causing you to feel dizzy if you get up too quickly from sitting or lying down.
This medicine may mask pain symptoms that could assist in the diagnosis of some diseases. You must tell your doctor that you take this medicine.
Tell your doctor if you are taking, have recently taken or might take any other medicines.
Some medicines may increase the side effects of Suboxone, these can be serious. Do not take any other medicines whilst taking Suboxone without first talking to your doctor, especially:
‐ Other opioid containing medicines such as methadone, certain painkillers and cough suppressants
‐ Antidepressants (used to treat depression) such as isocarboxazid, phenelzine, selegiline, tranylcypromine and valproate may increase the effects of this medicine.
‐ Sedative Hı receptor antagonists (used to treat allergic reactions) such as diphenhydramine and chlorphenamine.
‐ Barbiturates (used to cause sleep or sedation) such as phenobarbital, secobarbital
‐ Tranquilisers (used to cause sleep or sedation) such as chloral hydrate.
Clonidine (used to treat high blood pressure) may extend the effects of this medicine.
Anti-retrovirals (used to treat HIV) such as ritonavir, nelfinavir, indinavir may increase the effects of this medicine.
Some antifungal agents (used to treat fungal infections) such as ketoconazole, itraconazole, certain antibiotics, may extend the effects of this medicine.
Some medicines may decrease the effect of Suboxone. These include medicines used to treat epilepsy (such as carbamazepine and phenytoin), and medicines used to treat tuberculosis (rifampicin).
Naltrexone and nalmefene (medicines used to treat addictive disorders) may prevent the therapeutic effects of Suboxone. They should not be taken at the same time as Suboxone treatment because you may experience a sudden onset of prolonged and intense withdrawal.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. The risks of using Suboxone in pregnant women are not known. Your doctor will decide if your treatment should be continued with an alternative medicine.
When taken during pregnancy, particularly late pregnancy, medicines like Suboxone may cause drug withdrawal symptoms including problems with breathing in your newborn baby. This may appear several days after birth.

Your doctor will determine the best dose for you. During your treatment, the doctor may adjust the dose, depending upon your response to treatment.
The recommended starting dose for adults and adolescents over the age of 15 years is usually two Suboxone 2 mg/0.5 mg sublingual tablets.
This dose may be repeated to twice on day 1 depending on your needs.
You should be aware of the clear signs of withdrawal before taking your first dose of Suboxone. Your doctor will tell you when to take your first dose.
Starting treatment of Suboxone whilst dependent on heroin
If you are dependent upon heroin or a short acting opioid, your first dose should be taken when signs of withdrawal appear, at least 6 hours after you last used opioids.
Starting treatment of Suboxone whilst dependent on methadone
If you have been taking methadone or a long acting opioid, the dose of methadone should ideally be reduced to below 30 mg/day before beginning Suboxone therapy. The first dose of Suboxone should be taken when signs of withdrawal appear, and at least 24 hours after you last used methadone.
Take the dose once a day by placing the tablets under the tongue.
Keep the tablets in place under the tongue until they have completely dissolved. This may take 5-10 minutes.
Do not chew or swallow the tablets, as the medicine will not work and you may get withdrawal symptoms.

During the days after you start treatment, your doctor may increase the dose of Suboxone you take according to your needs. If you think that the effect of Suboxone is too strong or too weak, talk to your doctor or pharmacist. The maximum daily dose is 24 mg buprenorphine.
After a time of successful treatment, you may agree with your doctor to reduce the dose gradually to a lower maintenance dose.
Depending on your condition, the dose of Suboxone may continue to be reduced under careful medical supervision, until eventually it may be stopped.
Do not change the treatment in any way or stop treatment without the agreement of the doctor who is treating you.
If you or someone else takes too much of this medicine, you must go or be taken immediately to an emergency centre or hospital for treatment as overdose with Suboxone may cause serious and life- threatening breathing problems.
