Definition of Limited Nurse Prescribing (LNP): The administration of Nicotine Replacement
Therapy, which is a non prescription medicine (that can be freely purchased across the counter of a
pharmacy), without a doctor‟s prescription, for specified patients following stated limitations (see
below).
Principles
Abstinence from tobacco results in a very well defined tobacco withdrawal syndrome, which
includes a range of mood and physiological symptoms. Nicotine has a short half-life
(approximately 2 hours) and it is not uncommon for symptoms to appear in this timeframe.
NRT is an effective smoking cessation aid, and works primarily by reducing the severity of
urges to smoke (craving) and other tobacco withdrawal symptoms. It is therefore an
appropriate treatment for the management of these symptoms, even if the patient does not
wish to quit smoking long-term.
Nicotine should be offered to all inpatients who currently smoke,
or who have been smokefree for less than 30 days

Patient Group
Patients who:
Smoke and would not otherwise be able to
remain smokefree and/or are suffering from
nicotine withdrawal.
Are aged 18 years or over (NRT can be
administered to people aged 12 -17 yrs 1, with
a prescription from the medical team).
Have given verbal consent.
Inpatients identified as current
smokers should be offered
appropriate NRT, whether or
not they wish to quit long term.
This should enable them to be
more comfortably smokefree
during their hospital stay. This
may be crucial, especially for
those admitted with cardiorespiratory illness and/or
needing oxygen treatment.
Contraindications
Do not use patches with people who have an allergy to sticking plaster
Precautions
(note that these are not contraindications)
In general, any risk of using NRT would be expected to be less than the risk of
continued smoking.
NRT typically delivers less nicotine then smoking and less rapidly. More importantly, it does
provide the many other hazardous substances found in tobacco smoke.4,5 However in the
following patients, nurses should obtain agreement from a consultant or registrar before
administering NRT.
Patients who have suffered a serious cardiovascular event (eg MI) or stroke within in
the previous two weeks or with poorly controlled cardiovascular disease (see note 1)
Patients with unstable or worsening angina pectoris
Patients with serious cardiac arrhythmias
Patients on medications known to be affected by NRT e.g. theophylline
Patients undergoing skin flap surgical procedures (see note 2)
If these patients indicate that they are likely to continue to smoke, NRT lozenges or gum
(intermittent supply) is the preferred option.
Note 1: NRT has not been found to increase the risk of acute MI, stroke or sudden death.6
NRT can be used in patients post-MI once their blood pressure and heart rate have
stabilised
Note 2: There is evidence to show that tobacco use impairs wound healing.9 Nicotine may
play a role in this and so it is advisable that patients are tobacco free and nicotine free
before surgery. However, when a patient is still smoking, NRT presents less risk than
continued smoking

Mental Health Patients
Smoking stimulates the metabolism of clozapine and olanzapine. When a patient on these
medicines gives up smoking, their blood concentrations of either clozapine or olanzapine will
increase over the next two to four weeks. They can be given NRT, but ensure that the
consulting psychiatrist is aware that the patient has stopped smoking, as the dosage of these
drugs may need to be reduced.
NRT for Pregnant & Women who are breast-feeding
Although using nicotine products during pregnancy is not without risk, the main benefit of
using NRT is the removal of all other toxins contained in tobacco smoke. Furthermore, NRT
typically provides far less nicotine then tobacco smoke. Current expert opinion is that NRT
can be considered safe to use in pregnancy following an assessment of the risks and
benefits.4,7 In general, nicotine products such as lozenges, should be used in preference to
patches , as they deliver a lower total daily nicotine dose then patches4, and the supply is
intermittent. If patches are used, they should be removed overnight.
Regarding breast-feeding and NRT use, nicotine freely passes in and out of breast milk
depending on the concentration of nicotine in maternal blood (which is, in turn, affected by
cigarette consumption, frequency of breast-feeding and time between smoking and breastfeeding).4 Due to the relatively low oral availability of nicotine,8 it is unlikely that this very
low level of exposure is harmful to the infant.7 The importance of continuing to breast-feed,
regardless of smoking status, should be stressed.
Women in labour should be encouraged to take NRT only if smoking is the alternative.
The Smokechange service is able to provide support for pregnant or recently
birthed women, either in hospital or at home – call them on 0800 226 242

Who should not be prescribed NRT without consulting the doctor
Assessing Dependence
Ask two questions:How many cigarettes do you smoke per day?
How soon after waking do you smoke or wish to smoke your first cigarette?
Patients who smoke within 30 minutes of waking are considered highly dependent.2
Nicotine Replacement Therapy Self Learning Package
Page 7
Be aware that:People tend to under-report the number of cigarettes they smoke each day
People who have only recently cut down are likely to compensate by inhaling the
smoke from the fewer cigarettes more deeply
Dosage/ What Dose to Provide?
Cigarette
consumption
More than
10/day
Recommended NRT dose
Nicotine patch 21mg/24 hours + nicotine gum OR lozenge for PRN use
Dose depends on time to first cigarette:
- if <30 minutes after waking use 4mg gum OR 2mg lozenges
- if >30 minutes after waking use 2mg gum OR 1mg lozenges
Less than
10/day
Nicotine gum OR lozenge for PRN use
Dose depends on time to first cigarette:
- if <30 minutes after waking use 4mg gum OR 2mg lozenges
- if >30 minutes after waking use 2mg gum OR 1mg lozenges
If nil by mouth or does not tolerate gum or lozenges use a nicotine patch
14mg/day and if necessary titrate up to 21mg/day
A patient can use as much NRT as it takes for them to feel comfortable. In the rare case
that a patient is gets too much nicotine, they will begin to feel nauseous. If this happens,
try the medium strength (14mg) patch or suggest using fewer lozenges / gum.
Note:These recommended dosages are very conservative
Under-dosage causes failure of the drug to prevent nicotine cravings – many
smokers need more NRT than the guidelines recommend.
Combination Therapy
Many smokers are best cared for by providing combination therapy (patches +
lozenges /gum) which are safe and shown to be more effective then single products
alone. 3
Patches offer a sustained amount of nicotine during the day, with the lozenge / gum
being used „when necessary (ie PRN) to treat break-through cravings.
Lozenges and gum release nicotine more quickly then patches.
Young People (12 – 17years)
For young people who smoke more than 10/day – same as above
For those who smoke fewer than 10/day, offer low strength lozenge (1mg) or gum
(2mg) initially. Monitor after 24 hours and if cravings not controlled, increase the
dosage
Consult relevant parental consent guidelines before administering NRT to patients 1215 years

NRT Products Available within the CDHB
NRT patches (21mg and 14mg), lozenges (2mg and 1mg), gum (4mg and 2mg) and
inhalers can be accessed from the CDHB Hospital pharmacies. Detailed information
about how to use all of these products is found in the Clinical Pharmacological Bulletin:
NRT – managing inpatient nicotine dependence (intranet, clinical pharmacy department,
bulletins, 2010).
Ward Stock will most often include only 3 products - 21mg patches and both 1mg and 2mg
lozenges – as these products alone or in combination will address the immediate needs of
almost all patients
Product Dosage
Use
Patches
21mg/24h
Apply to clean, non-hairy, dry and unbroken
skin. Apply new patches to fresh skin site
daily. Do not use old site for 3 days. Some
redness may occur at site of placement.
Lozenges
1mg, 2mg
Apply 1 patch daily. Leave patch on for
24hours.
Initial onset can take 1-2 hours,
reaching peak concentration in 6-12
hours.
Suck one lozenge every 1-2 hours.
Usual dose 8-12 / day. Maximum of
25 (1mg) and 15 (2mg) lozenges /day.
When used in combination with
patches, lozenges should be sucked
only if there are break through
cravings (ie PRN use).
*Gum
2mg or
4mg
Chew and park 1 piece slowly for
30min. Usual dose 8-12/day.
Maximum of 25 (2mg) or 15 (4mg)
pieces/day.
Time to peak concentrations: ~2030min.
Inhaler
10mg
Dose usually 6-12 inhaler cartridges
daily.
Time to peak concentrations: ~15min
Use in combination with nicotine
patch: use 14mg/24h patch with 4-5
inhaler cartridges daily (max 12/day)
When urge to smoke is felt, suck the lozenge
until taste becomes strong, then park (tuck
between the cheek and gum). Repeat when
taste dissipates (each lozenge should last for
around 30 minutes).
When urge to smoke is felt, chew 1 piece of
gum until taste becomes strong: rest gum
between the cheek and gum, chew again
when taste fades; continue for 30min.
Mild adverse effects include hiccups, upset
stomach.
Use whenever there is an urge to smoke. Use
approx 6 cartridges for smokers of < 24
cigarettes/day and up to 12 cartridges for >40
cigarettes/day. Adverse effects include
mouth/throat irritation and cough which
usually resolve with continued use.

Monitoring
Craving / Urges to Smoke
All people commenced on NRT should be monitored
to assess how they are feeling in terms of urges to
smoke.
Approximately 24 hours after starting NRT, ask:
How often have you felt the urge to smoke in
the past 24 hours?
How strong have those urges been?
If experiencing a lot of urges to smoke or if urges
are strong, ask if patient would like to increase
dosage or try combined therapy (patch +lozenge,
even patch + patch for very heavily addicted
smokers). The aim of these questions is to assess
patient‟s tolerance and comfort level, with the
overall goal of keeping the patient comfortably
Smokefree
When monitoring
effectiveness of NRT it can
be useful to offer the
patient a 1 – 5 scale to
describe their intensity of
nicotine craving. 1
representing ‘totally fine
without smoking’ and 5
representing ‘I’d kill for a
smoke’. Anything 3 or up
requires additional NRT.
Symptoms of Overdose
Nicotine overdose, from NRT, in smokers is unlikely to occur. Smokers are used to large
quantities of nicotine from their tobacco smoke. It is far more common to underdose
smokers with NRT
Symptoms of nicotine overdose include nausea, vomiting, salivation, abdominal pain,
diarrhoea and sweating. Reduce dosage if these symptoms are experienced.

3
A progress note is entered into the patient‟s clinical notes detailing the
findings of assessment outlined in no‟s. 1-2 above. This progress note will
be signed and dated by the Registered Nurse making the assessment.
4
If the patients‟ smoking status fits the criteria, a Registered Nurse may
administer appropriate Nicotine Replacement Therapy (The RN must have
completed the online ABC training for health professionals). Only
medicines listed and within the ranges shown are permitted to be
administered.
All administration of Nicotine Replacement Therapy is to be accurately
entered on the medication chart (QMR0004), signed by the Nurse and
with the abbreviation RN added and the surname printed in block capitals
(Patches should be entered under the regular medications and lozenges,
inhalers and gum entered under the PRN section).
• All administration is recorded in clinical notes.
• The effects of medication and any adverse reaction are to be recorded
appropriately.
• The medical officer is to be contacted if Nicotine Replacement Therapy
is ineffective or an adverse reaction occurs.
• Provide the patient with the Smokefree Quit Pack
5
The following limitations are to be observed:
• NRT administered and documented on the QMR0004, (When possible
initial consultation with medical staff regarding administration should be
considered).
• Only for administration to persons aged 18 years and above, unless
prescribed by medical staff.
