Methadone
Methadone was first
synthesized during WWII by a German company, I.G. Farben; for use as a
painkiller on the battlefield. Being a synthetic opiate meant that there was no
need to rely on a supply of poppies for use in pain relief.
After the war the factory
where Methadone had been invented fell under American control and the first
clinical trials began in 1947. At first doctors thought Methadone would be a
revolutionary painkiller but by the early 1950s it was hardly being used at
all. In 1968 Drs Marie Nyswander and Vincent Dole, in America, were
looking for drugs to help opiate users when they read about methadone in the
medical literature. They found it helped their patients stop using opiates and
that tolerance was slow to develop - methadone maintenance treatment was
born. Methadone is a narcotic analgesic or a narcotic painkiller.
Methadone like other opiates
is addictive. The withdrawals from methadone can be worse but on the other hand
it doesn’t give a high like that of opiates, so people tend not to crave it as
much as they crave opiates.
Prescribed methadone can
provide a useful stage to get used to life without the buzz. It also has the
advantages of being:
Methadone treatment
accompanied by counseling and other forms of help is highly effective. This
means that for people who can’t stop taking opiates it is often much the lesser
of two evils and can be the basis on which to start to build a life away from
opiate use.
Methadone programmes have
essentially come about to reduce the harm that illegal opiate use has had upon
society. It is not a cure, but it can provide an opportunity for people to
get their lives stabilized.
The ideal dose at the start of
methadone treatment is one that:
-
Stops you suffering from
bad withdrawals
-
Doesn’t give you a bigger
habit
-
Is enough to get you
adjusted to taking methadone instead of other drugs
-
Removes physical craving
without getting you stoned
-
Provides stability
If you think methadone might
work for you, you will need to be assessed at the local A&D service in
Christchurch it
is at the Community Alcohol and Drug Service on 258 Armagh
St.
If you are successful at
getting on a programme you will have to prepare for a lifestyle change. You will
be required to consume your dose everyday at a pharmacy which, over time, will
place severe restrictions on your movements. Takeaways can be granted if certain
conditions are met, but this varies from region to region and you should examine
the criteria from the clinic in your area. Most places will reward good behavior
with takeaways ie. The more that you can show methadone is working for you, the
more relaxed the takeaway regime. However, most clinics do not allow more than 4
takeaways per week, so you can expect to pick-up from your pharmacy a minimum of
3 times a week.
You will be required to see a
doctor every month, and the case-manager assigned to you will also be present.
This will take place at a specialist clinic but later on in your treatment you
may get the option of having your own GP prescribe your methadone. You should
also expect to submit several urines per year usually this is done to monitor
the use of other opiates, but some clinics choose to monitor all substances that
one may consume. Once you are on methadone, your name will be on the books and
many aspects of your life that were previously private will no longer be so. In
short, you should be prepared for intrusions into some very personal
matters.
Methadone is NOT intended
for injection. It is an orally administered substance. When injected,
common side effects include local irritation with redness and extensive swelling
in the hands.
When methadone is taken
orally, the peak is about 70% as great and occurs after 4 hours. The duration of
action after oral administration is around 24-48 hours. Intravenously injected
methadone peaks almost immediately, and the duration of action is
lessened accordingly, around 12-24 hours.
Injecting methadone means it
metabolises much quicker and withdrawals will kick in well before the 24/36
hours of comfort that oral methadone can provide.
Oral methadone binds to the
cells in the liver, lungs and fat before moving into your bloodstream. It takes
three days to build up in your system, so injecting results in you feeling
unstable more often.
Due to the large amount of
particle-loaded fluids being injected, your liver and kidneys especially start
to take the toll and start failing. This is especially bad if you’re an
alcoholic, have Hep C or Hep B, as there is a much greater risk of damage to
these organs.
