1. What Buprenorphine 0.4mg Sublingual tablets are and what they are used for
Buprenorphine 0.4mg Sublingual tablets contain bupreorphine hydrochloride equivalent to
0.4mg buprenorphine.
Buprenorphine is one of a group of medicines used in opioid dependence. When it is used for the
treatment of patients addicted to opiate (narcotic) drugs, such as morphine and heroin, it acts as a
substitute for these drugs and therefore aids the patient in withdrawing from them over a period
of time. If treatment is stopped abruptly, withdrawal symptoms can occur.
These tablets are described as ‘sublingual’. This means that the tablet should be placed under the
tongue and kept there until fully dissolved which usually occurs within 5 to 10 minutes.

2. Before you take Buprenorphine 0.4mg Sublingual tablets
Buprenorphine 0.4mg Sublingual tablets should not be used:
● in children under the age of 16 years
● if you are allergic to buprenorphine or any of the other ingredients in this medicine
● if you have serious breathing problems
● if you have serious problems with your liver or if your doctor detects the development
of such a problem during treatment
● if you are intoxicated due to alcohol or have delirium tremens (the shakes and
hallucinations)
● if you are breast-feeding
● if you are pregnant (unless your doctor tells you to take it)
Tell your doctor if you have any of the following illnesses before treatment or develop them
during treatment as your doctor may need to reduce your dose of this medicine or you may need
extra treatment to control them.
● asthma or other breathing problems
● kidney disease
The tablets should be used exactly as prescribed by your doctor. Some people have died from
respiratory failure (inability to breathe) whilst using benzodiazepines (medicines used to treat
anxiety and sleep disorders) in combination with Buprenorphine and also when Buprenorphine
was not used according to doctor’s instructions.
Therefore whilst you are being treated with this medicine do not use benzodiazepines unless they
have been prescribed by your doctor.
Some cases of severe liver problems have occurred during treatment although they may not
necessarily have been caused by these tablets. If you develop severe fatigue, have no appetite or
if your skin or eyes look yellow tell your doctor immediately.
This medicine can cause withdrawal symptoms if you take less than four hours after you use a
narcotic (morphine, heroin or other related products).
This medicine can cause drowsiness, which may be made worse if you also drink alcohol or take
tranquillisers or anti-anxiety drugs. If you are drowsy do not drive or operate machinery.
This medicine can affect your ability to drive as it may make you sleepy or dizzy.
● Do not drive while taking this medicine until you know how it affects you.
● It is an offence to drive if this medicine affects your ability to drive.
● However, you would not be committing an offence if:
○ The medicine has been prescribed to treat a medical or dental problem and
○ You have taken it according to the instructions given by the prescriber or in the
information provided with the medicine and
○ It was not affecting your ability to drive safely.

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while
taking this medicine.
The tablets may cause your blood pressure to drop suddenly causing you to feel dizzy if you get
up too quickly from sitting or lying down.
Drug dependence may occur as a result of taking this medicine.
Athletes should be aware that this medicine may cause a positive reaction to anti-doping tests.
Are there any medicines that should not be taken at the same time as Buprenorphine 0.4mg
Sublingual tablets?
You should not use benzodiazepines (medicines used to treat anxiety and sleep disorders) whilst
you are taking this medicine unless they are prescribed by your doctor.
Strong pain killers and cough medicines containing opioid-related substances, certain antidepressants including monoamine oxidase inhibitors, sedating antihistamines, sedatives, antianxiety drugs, certain drugs for high blood pressure and antipsychotic drugs may increase the
effects of buprenorphine.
Ketoconazole a medicine used for the treatment of fungal infections can increase the effects of
Buprenorphine if both are taken at the same time. If you are taking ketoconazole or any of the
following medicines: gestodene, troleandomycin, the HIV protease inhibitors ritonavir, indinavir
and saquinavir you should tell your doctor or pharmacist as they may need to reduce your dose
of buprenorphine.
Also tell your doctor or pharmacist if you are taking any of the following medicines:
phenobarbital, carbamazapine, phenytoin, rifampicin. You will be closely monitored whilst you
are taking these medicines at the same time as buprenorphine.
Be sure to tell your doctor if you are taking a blood thinning agent called phenprocoumon.
If you are taking any other medicines you should tell your doctor or pharmacist before you begin
treatment with buprenorphine.
Do not drink alcohol or take medicines that contain alcohol whilst you are being treated with
buprenorphine. Alcohol and certain other medicines (as listed above) increases the sedative
effects of buprenorphine which can make driving or operating machinery hazardous.

3. How to take the tablets
The tablets are administered sublingually. This means that you must place the tablet under your
tongue and allow it to dissolve which will take 5 to 10 minutes. This is the only effective and

safe way the tablets should be taken. Do not chew or swallow them whole as this will make them
ineffective.
Your doctor will tell you how many 0.4mg Sublingual tablets to take and you should always
follow his advice.
Adults and children over the age of 16 years: the initial dose is from 0.8 to 4mg administered
once a day.
For drugs addicts who have not undergone withdrawal: one dose of 0.4mg Sublingual tablets
at least six hours after the last use of the opioid (narcotic) or when the first signs of craving
appear.
For patients receiving methadone: before beginning treatment your doctor should reduce your
dose of methadone to a maximum of 30mg a day.
These tablets may cause withdrawal symptoms in patients who are dependent on methadone.
During your treatment, your doctor may increase your dose to a maximum single daily dose of
32mg depending upon your response.
After a period of successful treatment, your doctor may gradually reduce your dose. Depending
on your condition your dose may continue to be reduced under careful medical supervision until
it is stopped altogether. Do not suddenly stop taking these tablets as this may cause withdrawal
symptoms.
What to do in the case of overdose
You should contact your doctor immediately.
What do to if you forget to take your tablets
You should tell your doctor and follow his or her instructions.
