  14. All NRTs are not the same

  15. Use an adequate dose • Dose should be sufficient to control withdrawal symptoms and cravings • If in doubt, use more – higher doses are safe • Heavier smokers and faster nicotine metabolisers (women) need larger doses eg 2 patches + oral NRT • 4mg gum and lozenges if TTFC <30mins

  16. Nicotine patch • Full strength patch if ≥ 10 cigs per day • Apply to clean, dry, hairless skin on upper back, chest or arm • Rotate site daily • Side effects: • skin rash • disturbed sleep and vivid dreams • Stead LF. NRT for smoking cessation. Cochrane 2012
