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.
