4.10.2 Nicotine dependence

First Line
Second Line
Specialist
Hospital Only

To optimise the results from smoking cessation programmes it is advised that patients access motivational support from specialist services.

Refer all people who smoke to a smoking cessation service for behavioural support and pharmacotherapy. Some local community pharmacies and GP practices may offer a level 2 service. Level 3 services can be accessed via:

NICE NG209: Tobacco: preventing uptake, promoting quitting and treating dependence covers support to stop smoking for everyone aged 12 and over, and help to reduce people's harm from smoking if they are not ready to stop in one go.

NG209 also includes advice regarding nicotine-containing e-cigarettes and vaping. At the time of writing, these products are not prescribable on the NHS but can be purchased, and may be available from some specialist smoking cessation services.

MHRA Drug Safety Update (November 2023): E-cigarette use or vaping: reminder to remain vigilant for suspected adverse reactions and safety concerns and report them to the Yellow Card scheme:

  • Document use of e-cigarette products (’vapes’ or ‘vaping’) in the medical records for all patients when taking a medical history. Refer to the safety update for information to record.
  • Advise patients to be vigilant about suspected adverse reactions that occur after the use of e-cigarettes and e-liquids, and to purchase and use legally compliant (‘notified’) e-cigarette and e-liquid products. Refer to the safety update for advice to give to patients on checking whether products are legally compliant.
  • Report suspected adverse reactions or safety concerns to the Yellow Card Scheme.

For training resources refer to the National Centre for Smoking Cessation and Training (NCSCT) standard for training in smoking cessation treatments.

Nicotine dependence may be assessed with the Fagerström Test or the shorter Heaviness of Smoking Index (see here).

Stopping smoking in one go is the best approach, however if someone does not want, or is not ready, to stop smoking in one go, a harm reduction approach (e.g. cutting down before stopping, smoking reduction, or temporarily not smoking) may be appropriate.

Drug interactions with smoking

Tobacco smoke can induce liver enzymes, affecting drug metabolism. Some medicines may need dose adjustment or monitoring if a person stops or starts smoking.

Monitor people's use of prescribed medicines that are affected by smoking (or stopping smoking) for efficacy and adverse effects. Medicines that are affected include: clozapine, olanzapine, theophylline and warfarin. For more information, refer to the BNF, individual product SmPCs and:

Pregnancy and breastfeeding

Do not offer cytisine (cytisinicline), varenicline or bupropion to pregnant or breastfeeding women.

Consider NRT at the earliest opportunity in pregnancy and continue to provide it after pregnancy if the woman needs it to prevent a relapse to smoking, including if the pregnancy does not continue.

Advise pregnant women who are using nicotine patches to remove them before going to bed.

To optimise the results from smoking cessation programmes it is advised that patients access motivational support from specialist services.

Refer all people who smoke to a smoking cessation service for behavioural support and pharmacotherapy. Some local community pharmacies and GP practices may offer a level 2 service. Level 3 services can be accessed via:

Most smoking-related health problems are caused by other components in tobacco smoke, not by the nicotine. Any risks from using NRT are much lower than those of smoking. Nicotine levels in NRT are much lower than in tobacco, and the way these products deliver nicotine makes them considerably less addictive than smoking.

Agree a quit date (unless the person is adopting a harm reduction approach) and ensure the person has NRT ready to start the day before the quit date. In most cases NRT may be provided for up to 12 weeks, however there may be circumstances in which an individual would benefit from extended use e.g. pregnant women, people using a harm reduction method, or those who are very close to achieving a quit and whose attempt might be threatened by withdrawal of NRT. Appropriate intervals for prescribing will depend on the individual’s circumstances but are likely to be every two weeks during the first month; this may be extended to 4-weekly supplies for the rest of the quit attempt.

The person may be supported with ongoing NRT and behavioural support by a stop smoking advisor if accessing smoking cessation services.

Alternatives to long-term NRT provision include consideration of nicotine-containing e-cigarettes or vapes. At the time of writing, these products are not prescribable on the NHS but can be purchased, and may be available from some specialist smoking cessation services. Specialist smoking cessation services may be able to provide individual advice and support.

  • Report suspected adverse reactions or safety concerns to the Yellow Card Scheme.

Long-acting NRT

Advise people that use of a combination of short-acting and long-acting NRT alongside behavioural support, are more likely to result in them successfully stopping smoking.

Patches should be applied to dry non-hairy skin. The site of application should be rotated, avoiding the same area for several days.

16-hour transdermal patches

The 16-hour patches may help avoid vivid dreams and sleep disturbance, which may be associated with the 24-hour patches. They are also the preferred option for pregnant women.

Dose

  • Apply one patch each morning for 16 hours and remove the patch before going to bed. A new patch is applied to a different site the following morning.
24-hour transdermal patches

Pregnant women who are using nicotine patches should remove them before going to bed; 16-hour patches (above) are therefore preferred for these women.

Refer all people who smoke to a smoking cessation service for behavioural support and pharmacotherapy. Some local community pharmacies and GP practices may offer a level 2 service. Level 3 services can be accessed via:

Do not offer cytisine (cytisinicline), varenicline or bupropion to pregnant or breastfeeding women

Cytisine (Cytisinicline)
  • Tablets 1.5mg (£115.00 = 100 tablets)

Indications

  • Smoking cessation in adults, as part of a programme of behavioural support

Dose

  • Adults aged 18-65 years:
    • Cytisine is taken in a reducing regimen over 25 days (see table below); the NCSCT has produced a helpful dosing guide. Smoking should be stopped no later than on the 5th day of treatment.
    • Not recommended in patients with any degree of renal or hepatic impairment due to lack of clinical experience.

Notes

  1. Do not offer cytisine to pregnant or breastfeeding women, people under 18 or over 65 years of age, or those with unstable angina, history of recent myocardial infarction, clinically significant arrhythmias or who have had a recent stroke (refer to SmPC for additional information).
  2. Women of childbearing potential must use highly effective contraception during treatment; women using systemically acting hormonal contraceptives should add a second barrier method (see note b)
    1. Specialist smoking cessation services should ensure that highly effective contraception is in place and that the GP is informed of this when recommending cytisine.
    2. The effect of cytisine on hormonal contraception is unknown. Additional barrier methods should be used when women are using systemically acting hormonal contraceptives, including combined hormonal methods (i.e. combined oral contraceptive pills, vaginal ring, and patch), progestogen-only pills (POP), depot medroxyprogesterone acetate injection, and contraceptive progestogen implants.
  3. Interactions: Cytisine should not be used with anti-tuberculosis drugs.
  4. Smoking (or use of other products containing nicotine) should not be continued during treatment as this may aggravate adverse reactions. In case of treatment failure, the treatment should be discontinued and may be resumed after 2 to 3 months.
  5. Cytisine should normally be prescribed only as part of a programme of behavioural support.
Days of treatmentRecommended cytisine doseMax daily dose of cytisine
Day 1 to day 31 tablet every 2 hours6 tablets (9mg)
Day 4 to day 121 tablet every 2.5 hours5 tablets (7.5mg)
Day 13 to day 161 tablet every 3 hours4 tablets (6mg)
Day 17 to day 201 tablet every 5 hours3 tablets (94.5mg)
Day 21 to day 251 or 2 tablets per day2 tablets (3mg)
Varenicline
  • Tablets 500micrograms, 1mg (£23.21= 28 tablets)

Indications

  • Smoking cessation in adults, as part of a programme of behavioural support

Dose

  • Initially 500micrograms once daily for 3 days, increased to 500micrograms twice daily for 4 days, then 1mg twice daily for 11 weeks.
    • Dose may be reduced if not tolerated to 500micrograms twice daily.
    • Usually started 1–2 weeks before target stop date but can be started up to a maximum of 5 weeks before target stop date (see also note 2).
    • 12-week course can be repeated in abstinent individuals to reduce risk of relapse.
  • Hepatic impairment: No dosage adjustment necessary
  • Renal Impairment:
    • Mild or moderate impairment (CrCl ≥30 to ≤80mL/min): No dosage adjustment necessary
    • Severe impairment (CrCl <30mL/minute): initial dose 500micrograms once daily, increased after 3 days to 1 mg once daily

Notes

  1. Do not offer varenicline to pregnant or breastfeeding women, or to people under 18 years of age.
  2. A gradual approach to quitting smoking with varenicline may be considered for patients who are not able or willing to quit abruptly. Patients should reduce smoking during the first 12 weeks of treatment and quit by the end of that treatment period. Patients should then continue taking varenicline for an additional 12 weeks for a total of 24 weeks of treatment.
  3. NICE TA123: Varenicline is recommended within its licensed indications as an option for smokers who have expressed a desire to quit smoking (July 2007).
    1. Varenicline should normally be prescribed only as part of a programme of behavioural support.
Bupropion
  • Modified-release tablets 150mg (£41.76 = 60 tablets)

Indications

  • An aid to smoking cessation in combination with motivational support in nicotine-dependent patients

Dose

  • Start 1–2 weeks before target stop date, initially 150mg daily for 6 days then 150mg twice daily; period of treatment 7–9 weeks; discontinue if abstinence not achieved at 7 weeks; consider maximum 150mg daily in patients with risk factors for seizures and the elderly

Notes

  1. Do not offer bupropion to pregnant or breastfeeding women, or people under 18.
  2. Bupropion has been associated with seizures (see note 5 below), which occur in around 1 in 1,000 patients treated (0.1%).
  3. Insomnia is a very common adverse event which can be reduced by avoiding bedtime doses of bupropion (provided there is at least 8 hours between doses).
  4. Patients should exercise caution before driving until they know whether bupropion affects their ability to drive.
  5. Bupropion is contra-indicated in patients with a history of seizures or of eating disorders, a history of bipolar disorder, a CNS tumour, or who are experiencing acute symptoms of alcohol or benzodiazepine withdrawal. Bupropion should not be prescribed to patients with other risk factors for seizures unless the potential benefit of smoking cessation clearly outweighs the risk. Factors that increase the risk of seizures include concomitant administration of drugs that can lower the seizure threshold (e.g. antidepressants, antimalarials (such as mefloquine and chloroquine), antipsychotics, quinolones, sedating antihistamines, systemic corticosteroids, theophylline, and tramadol), alcohol abuse, history of head trauma, diabetes, and use of stimulants and anorectics.
  6. MHRA Drug Safety Update (November 2020): Bupropion (Zyban): risk of serotonin syndrome with use with other serotonergic drugs
    1. Cases of serotonin syndrome have been reported in association with bupropion and co-administration with serotonergic drugs, for example
      1. selective serotonin reuptake inhibitors (SSRIs)
      2. serotonin norepinephrine re-uptake inhibitors (SNRIs).
    2. If concomitant prescribing with other serotonergic drugs is clinically warranted:
      1. do not exceed the recommended dose
      2. remind patients of the milder symptoms of serotonin syndrome at initiation of treatment and at any change of dose and the importance of seeking medical advice if they occur
      3. if serotonin syndrome is suspected, either decrease the dose of bupropion or withdraw therapy depending on the severity of the symptoms.
    3. Advice to give to patients:
      1. if you are told you may be at risk of serotonin syndrome, be aware of symptoms, including mild signs such as nausea, vomiting, and diarrhoea or increased heart rate and agitation (see Drug Safety Update for full list) and talk to your prescriber if you experience these
      2. never exceed the prescribed dose of bupropion.
