Nicotine Replacement Therapy (NRT)
Nicotine Replacement Therapy (NRT) is
available
at
prescription cost
(or free if you are exempt) via our Stop Smoking Advisers. Call us on
0845 27 07 222 for more information.
NRT
has been shown to
double your chances of stopping smoking. It is not a
magic cure. NRT does not completely replace the amount of nicotine you
would receive when you smoke, but gives you a reduced amount. This means
you might still experience withdrawal symptoms but these will be less
than if you quit 'cold turkey' (without any product or aid).
Nothing will help you give up smoking if you are not
determined to do it
and half hearted attempts generally do not succeed. Only
you can do it!
The reason some people do not benefit from using NRT is that they may
not have used it properly or in insufficient quantities. It is very
unusual for people to become addicted to NRT products.
Caution: Persons with a serious medical condition such as heart
disease, diabetes, thyroid disease, peptic ulcers or skin problems
should consult with a doctor before using NRT.
Nicotine Gum
This is available in two strengths:
2mg and 4mg and in
several flavours.
The 4mg gum is better for more dependant smokers usually smoking more
than 20 a day. The gum allows
good control of the dose of nicotine
because a piece can be chewed whenever the need for more nicotine
arises. A chew-rest-chew technique should be used so that the nicotine
is absorbed through the mouth lining and is not swallowed. Hold the gum
between the cheek and the gum between chewing. When the taste fades, it should be chewed again and then
parked. Any swallowed nicotine is wasted as it is not absorbed when
digested. Gum should be used for 3 months and then gradually reduced by
switching to sugar free gum or reducing the number of pieces chewed.
Most smokers will use 10-15 pieces of gum per day. The gum can taste
unpleasant at first although people do get used to the taste of it. The
gum can cause mouth ulcers and indigestion.
Patch
The patch delivers a measured dose of nicotine through the skin. They
are available as 16 hour and 24 hour versions in varying doses. The
patch is
very discreet and
easy to use, being put on each morning and
with the 16 hour patch, taken off at night. High dose patches have been
shown to be more
effective than low dose patches for smokers of more
than 15 cigarettes a day. If sleep disturbances occur with the 24 hour
patch, try switching to a 16 hour patch. Patches should be applied to
clean, dry non-hairy skin - the upper arm or trunk are most commonly
used. Use a different site each day to minimise any irritation. It can
take up to 2 hours after applying the patch before the full dose is
received. Some people find that taking gum or lozenge to supplement the
patch more effective. At present, labelling on NRT products restricts
usage to just one product. However there is little scientific evidence to
support this.
Nasal
Spray
This is the strongest form of NRT available and is generally recommended
for more dependent, heavier smokers. This is the most rapid form of
nicotine delivery available and the nicotine is absorbed through the
permeable membrane of the nose.
The spray is a bottle of nicotine solution that delivers a dose of
nicotine in a spray when the top is pressed down. Again it allows
good
control of the dose. It can be difficult to
use, causing sore nose, runny eyes sneezing and be generally unpleasant,
although people who persevere soon get used to it and are able to
tolerate it.
Inhalator
This is a plastic mouthpiece with a supply of replaceable nicotine
cartridges that fit inside it. The nicotine is absorbed in the mouth and
throat, not the lungs. It is
useful
for smokers who like the ritual of smoking and allows
control over the dose.
It takes about 20 sucks on the inhalator to get the same amount of
nicotine to 1 puff of a cigarette. Some people describe the taste as
unpleasant but it doesn't take long to get used to it.
Sublingual
tablet / microtab
This is a small tablet which is placed under the tongue where it
dissolves over a period of about 30 minutes. It is not chewed, sucked or
swallowed. It is
discreet
and
flexible
and similar to the gum, gives
good control over the dose of nicotine. Once again this is not a
pleasant taste and can cause mouth ulcers and indigestion.
Lozenge
The lozenge is
like a sweet and should be sucked slowly.
The nicotine is
absorbed through the lining of the mouth, in the same way as the gum and
microtab, and is also available in two main doses - 2mg and 4mg.
The lozenge will dissolve completely after approximately 30 minutes. It offers
good control over
nicotine dose. This also can taste unpleasant, cause mouth ulcers and
cause indigestion.
Non-nicotine cessation aids
Zyban
(Bupropion)
This was originally marketed as an anti-depressant in America. It was
found that people were giving up smoking as a result of taking this
drug. It is not understood how it works but it
blocks the
neurotransmitters that make smoking pleasurable. In the UK, this product
is only available on prescription and only suitable for a limited number
of people. There are also a number of side effects, which your GP should
explain to you.
Champix (Varenicline)
Champix tablets contain the active ingredient Varenicline, which is a
medicine used to help people who are addicted to nicotine to give up
smoking. Varenicline works by stimulating the nicotinic receptors in the
brain. This produces an effect that
relieves the craving
and withdrawal symptoms you can get when you stop smoking. At the same
time, Varenicline blocks nicotine from acting on the receptors. This
prevents any nicotine inhaled in tobacco smoke from having a rewarding
and enjoyable effect.
In the UK, this product is only available on prescription. There are also a number of side effects, which your GP should
explain to you.
Glucose
Tablets
These are the normal energy sweets you can buy over the counter in your
local Pharmacy. There is considerable research being carried out on the
effects of taking glucose to minimise the cravings for cigarettes. It is
thought that the brain can be confused by the effect of feeling hungry
and the craving for a smoke. So taking a glucose tablet to give an
energy boost fools the brain into thinking it has been
satisfied, thus
the craving is diminished. It has been found that people who take
glucose tablets/sweets tend
not to put on so much weight on stopping
smoking.
Nicobrevin
Capsules of menthyl valerate (a mild sedative), quinine (a mild appetite
suppressant), camphor and eucalyptus (to reduce mucus secretion and
accumulation).
Available without prescription. There is no evidence for
long-term success. Not to be used in pregnancy.
Herbal
Cigarettes
These contain no nicotine but do contain tar and produce carbon
monoxide.
Tar is the most cancer causing property
of the cigarette and carbon monoxide is the poison that kills people.
Hence they are not a safe alternative to replace normal cigarettes.
Using these to cut down and give up gradually is not a proven way of
giving up smoking.
Cutting
down
gradually
Evidence shows that cutting down before giving up smoking can be
counter productive.
The few cigarettes that are smoked become very important and are smoked
in such a way as to maintain the same levels of nicotine as before the
person had cut down. People who cut down usually gradually often sneak
back up to their old levels of smoking. |
