What
is buprenorphine?
Buprenorphine (‘bup’, ‘B’)
is available by prescription, under the name of Subutex, as a
treatment for Opioid dependence. It has been found to be effective
in reducing the need to continue using Opioids (buprenorphine
maintenance) and also in helping people to withdraw.
Buprenorphine (pronounced bew-pre-nor-feen) has been found to
be effective in treating opiod dependence by:
· Preventing withdrawal symptoms, such as cravings for
heroin
· Blocking the effects of heroin. Using heroin will not
provide the ‘high’ that would normally be expected,
therefore it takes away one of the main reasons to use heroin.
How effective is buprenorphine?
The effectiveness of any treatment, including
for heroin or other Opioid dependency (addiction), is more likely
to be successful if it is part of a comprehensive treatment program.
Often, a range of factors contributes to an individual’s
use of drugs. Thus, it is strongly recommended that those wanting
to remain free of heroin engage in a treatment program that addresses
the physical (the body), psychological (the mind) and environmental
issues relating to the person’s drug use. This may involve
combining several treatment approaches, such as buprenorphine
maintenance, counseling, alternative or holistic therapies such
as massage and naturopathic treatment; and developing a positive
support network including peers, family and friends and support
groups.
As with any type of treatment or approach to addiction, buprenorphine
maintenance may be effective for some people but will not suit
everyone. A doctor or drug counselor who spends time assessing
the person’s specific situation and explaining different
options will recommend an approach that is appropriate for that
individual.
Advantages of buprenorphine maintenance
treatment
There are many benefits of being on buprenorphine
maintenance, when compared with continuing the use of opiates:
· Maintenance treatment holds the person stable while they
readjust their lives. The person may decide later to work towards
reducing their dose of buprenorphine until they no longer require
medical treatment.
· Using buprenorphine on its own is unlikely to result
in an overdose.
· Health problems are reduced or avoided, especially those
related to injecting, such as HIV, hepatitis B and hepatitis C
viruses, skin infections and vein problems.
· Doses are required only once a day, sometimes even less
often, because buprenorphine’s effects are long lasting.
· Buprenorphine is much cheaper than heroin.
· Staying off heroin can provide the opportunity to experience
more ‘life opportunities’, such as. Greater personal
happiness, more close and stable relationships with others, employment
and more money to buy goods for personal enjoyment.
What are the side effects?
Buprenorphine is generally well tolerated;
however, some side effects have been
Reported. The most common side effects are similar to those listed
under the section ‘Buprenorphine withdrawal’.
Related issues
Before a person commences any drug treatment
program, it is important that all the relevant information has
been explained to them by a qualified health professional and,
where appropriate, to carergivers such as family, friends etc.
This includes the length of the program, how much it costs, what
other supports are included or recommended, all the risks and
side effects, and any other health issues to consider. When deciding
on the suitability of buprenorphine maintenance, the following
issues should also be discussed with a health professional:
· Existing liver conditions, such as acute hepatitis
· Respiratory illnesses
· If a woman is pregnant, wanting to become pregnant or
breastfeeding (it has not been established that using buprenorphine
during pregnancy is safe)
· Buprenorphine may impair the ability to drive and operate
machinery safely, so it may not be appropriate for people in certain
occupations.
How
is buprenorphine taken?
A Subutex tablet must be placed under the
tongue and allowed to dissolve. Chewing or swallowing the tablet
will make it ineffective. Injecting Subutex is dangerous, and
can lead to severe vein damage, blood clots and other health complications.
Subutex dissolves within 2–8 minutes after placing it under
the tongue. The effects begin within 30–60 minutes of taking
the dose and peak within 2–4 hours, lasting between 4 hours
to three days, depending on the dosage.

What
is the right dosage?
The dosage of buprenorphine often varies
for each person. As a guide, doses range from 4 milligrams to
32 milligrams per day for people with heroin dependence. A health
practitioner should be informed of any side effects that are experienced,
so that the dosage can be adjusted where appropriate. When first
starting on buprenorphine maintenance, it may take a number of
days (typically from three to seven days) for the effects of buprenorphine
to become stable in the body. Continuing heroin use can make it
difficult for the person to stabilize.
Missed doses
If a person misses their buprenorphine doses
for more than five days in a row, they will need to undergo a
review by the prescribing health professional. If this occurs,
it is recommended that the person start again on a lower dose
of buprenorphine.
Using buprenorphine with other drugs
Combining the use of any drugs can increase
or alter the effects that are usually experienced from using the
individual drug. It is often difficult to predict the consequences
of combining the use of different drugs.
It is particularly important to avoid using other depressant drugs,
such as benzodiazepines (‘benzos’), e.g. Valium, with
buprenorphine. Using benzodiazepines with buprenorphine may lead
to breathing difficulties, coma or death.
Using buprenorphine with heroin or other opiates, such as methadone,
increases the chances of experiencing ongoing withdrawal symptoms.
Always check with your doctor or pharmacist before using buprenorphine
with alcohol, medicines or other drugs.
Phases of treatment
The induction phase is the medically monitored
startup of buprenorphine therapy. Buprenorphine for induction
therapy is administered when an opioid-addicted individual has
abstained from using opioids for 12–24 hours and is in the
early stages of opioid withdrawal. If the patient is not in the
early stages of withdrawal, i.e., if he or she has other opioids
in the bloodstream, then the buprenorphine dose could precipitate
acute withdrawal. Induction is typically initiated as observed
therapy in the physician’s office and may be carried out
using either Suboxone® or Subutex®, dependent upon the
physician’s judgment. As noted above, Buprenex®, the
parenteral analgesic form of buprenorphine, is not FDA-approved
for use in opioid addiction treatment.
The stabilization phase
has begun when a patient has discontinued or greatly reduced the
use of his or her drug of abuse, no longer has cravings, and is
experiencing few or no side effects. The buprenorphine dose may
need to be adjusted during the stabilization phase. Because of
the long half-life of buprenorphine it is sometimes possible to
switch patients to alternate-day dosing once stabilization has
been achieved.
The maintenance phase is
reached when the patient is doing well on a steady dose of buprenorphine
(or buprenorphine/naloxone). The length of time of the maintenance
phase is individualized for each patient and may be indefinite.
The alternative to going into (or continuing) a maintenance phase,
once stabilization has been achieved, is medically supervised
withdrawal. This takes the place of what was formerly called “detoxification.”
Buprenorphine withdrawal
Withdrawal from long-term use of buprenorphine
may produce symptoms similar to those experienced from heroin
withdrawal. However, withdrawal symptoms tend to be milder with
buprenorphine than those from methadone and other opioids.
Withdrawal symptoms vary from person to person, but may include:
· Cold- or flu-like symptoms
· Headaches
· Sweating
· Aches and pains
· Sleeping difficulties
· Nausea
· Mood swings
· Loss of appetite.
These effects usually peak in the first two to five days. Some
mild effects may last a number of weeks.
Where can I get buprenorphine and
what does it cost?
Buprenorphine may only be prescribed by a
doctor who has a permit from the Department of Human Services
(DHS). Like methadone, buprenorphine is subject to a dispensing
fee, currently about $5.00 per dose.
