1. WHAT BUPRENORPHINE SUBLINGUAL TABLETS ARE AND WHAT THEY ARE USED FOR

Buprenorphine belongs to a group of medicines called opioid analgesics (also known as “opiates” or “narcotics”). Opioid analgesics, such as morphine or diamorphine (heroin), are often subject to abuse, which can lead to dependence (addiction). If you are addicted to these drugs, you need a regular dose to feel “normal”. Otherwise you will develop withdrawal symptoms within a day or so of the last dose. Withdrawal symptoms include sweating, feeling hot and cold, runny eyes and nose, feeling or being sick, diarrhoea, stomach cramps, poor sleep and just feeling awful.

Buprenorphine Sublingual Tablets are used as a substitution (replacement) treatment in patients who are addicted to opioid drugs such as heroin and morphine. The tablets prevent or reduce the unpleasant withdrawal symptoms experienced when addicts stop using opioid drugs.

Treatment with Buprenorphine Sublingual Tablets may form one aspect of a specialist support programme aimed at resolving opioid addiction.

The tablets are not to be used for pain relief purposes.

Taking other medicines

Tell your doctor if you are taking or have recently taken any of the following medicines as they may interact with Buprenorphine Sublingual Tablets.

The following medicines have sedative effects (make you feel sleepy/drowsy). These effects are increased if these medicines are taken while you are being treated with buprenorphine:

  • benzodiazepines (used for treatment of anxiety or sleep disorders) e.g. diazepam and temazepam: you should not take these medicines while you are taking buprenorphine, unless prescribed by your doctor because this combination can be fatal if the correct dose is not carefully determined
  • barbiturates and other medicines used for the treatment of anxiety or sleep disorders
  • other medicines containing opioid-related medicines e.g. codeine, dihydrocodeine and morphine (used as strong painkillers and in some cough medicines),
  • medicines used for the treatment of depression, including medicines known as monoamine oxidase inhibitors (MAOIs) e.g. phenelzine
  • antihistamine medicines (used for treatment of allergy and/or hay fever) e.g. promethazine and chlorphenamine
  • medicines known as antipsychotics (used for the treatment of schizophrenia) e.g. chlorpromazine and haloperidol
  • certain medicines for the treatment of high blood pressure (antihypertensives) e.g. clonidine.

If you are taking any of the following medicines, your doctor may need to prescribe a lower dose of buprenorphine:

  • the antifungal medicine, ketoconazole
  • medicines used to treat infections caused by viruses (antiviral agents) e.g. ritonavir, saquinavir and indinavir, which are used in the treatment of HIV infections
  • oral contraceptive medicines containing gestodene
  • certain medicines called ‘macrolide antibiotics’ (used for the treatment of infections).

If you are taking any of the following medicines, your doctor may need to prescribe a higher dose of buprenorphine:

  • medicines used for the treatment of epilepsy e.g. phenobarbital, carbamazepine and phenytoin

Pregnancy and breast-feeding

Before taking these tablets, tell your doctor if you are pregnant or trying to become pregnant. If you become pregnant during treatment with buprenorphine, tell your doctor straight away.

3. HOW TO TAKE BUPRENORPHINE SUBLINGUAL TABLETS

You must place the tablet under your tongue (sublingual) and allow it to dissolve, which will take 5 to 10 minutes. This is the only way to take the tablets. Do not chew or swallow them whole, as they will not work.

Your doctor will tell you how many tablets to take and you should always follow this advice.

To avoid sudden withdrawal symptoms, treatment with Buprenorphine Sublingual Tablets should be given when there are already clear signs of withdrawal symptoms.

Adults and children over the age of 16 years: when beginning treatment the dose is between 0.8 to 4 mg, taken once a day.

For drug addicts who have not had any withdrawal treatment: one dose of Buprenorphine Sublingual Tablets should be taken at least 6 hours after the last use of the opioid (narcotic such as morphine or heroine), or when the first signs of craving appear. If you take it less than six hours after you use a narcotic you may get withdrawal symptoms.

For patients taking methadone: before beginning treatment, your doctor should reduce your dose of methadone to not more than 30 mg a day. Buprenorphine Sublingual Tablets may cause withdrawal symptoms in patients who are dependent on methadone if used within 24 hours of the last dose of methadone.

During your treatment, your doctor may increase your dose of Buprenorphine Sublingual Tablets, to a maximum single daily dose of 32mg, depending upon your response. Once you have been stable for a while, your doctor will gradually reduce your dose and it may be possible to stop it altogether. Do not suddenly stop taking the tablets, as this may cause withdrawal symptoms.

If you take more Buprenorphine Sublingual Tablets than you should

Tell your doctor immediately or contact your nearest hospital casualty department. Remember to take the pack and any remaining tablets with you.

If you forget to take Buprenorphine Sublingual Tablets

You should tell your doctor and follow their instructions. Do not take a double dose to make up for the missed dose, unless your doctor tells you to.

If you stop taking Buprenorphine Sublingual Tablets

Do not suddenly stop taking the tablets unless told to do so by your doctor, as this may cause withdrawal symptoms.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
