Before taking Nicotine Gum (Nicorette®; Nicotinell®), what precautions must I follow?

​You should stop smoking once you start to use NRT. Smoking and using NRT at the same time may increase the risk of adverse effects from the additive effects of nicotine in your body.
If you continue to feel the urge to smoke or experience severe nicotine withdrawal symptoms even after using the NRT gums, please inform your healthcare professional as you may need other types of NRT.
Inform your healthcare professional if:
● You are pregnant, planning to become pregnant, or breastfeeding.
● You recently had a heart attack or stroke.
● You have active peptic ulcer disease.
● You are using dentures.
● You have any other medical conditions.
● You are taking any other medications, including supplements, traditional medications and herbal remedies.
● You are less than 18 years old.

What food or medicine must I avoid when I take Nicotine Gum (Nicorette®; Nicotinell®)?

​● Avoid coffee, tea, juices, acidic and fizzy drinks 15 minutes before and during use of nicotine gum as this may reduce nicotine absorption.
● Nicotine may reduce the effect of certain medications. When NRT dose is reduced or stopped, adjustments to these medications may be necessary.
● These medications include:
        o Benzodiazepines (e.g. diazepam, lorazepam)
        o Insulin
        o Beta-blocker (e.g. bisoprolol, atenolol)
        o Opioid painkillers (e.g. codeine)
● Inform your doctor or pharmacist about other medications – including over-the-counter medications, supplements and traditional/herbal remedies – that you are currently taking as they may affect the way you benefit from NRT.
