Nicotine mouth spray is available as:

  • Nicorette® Quickmist 1 mg per spray (each mouth spray contains at least 150 sprays)
  • It comes in a fresh mint or cool berry flavour.


  • Use 1–2 sprays in the mouth when the urge to smoke occurs or to prevent cravings.
  • Maximum dose: Do Not Use More Than 4 sprays/hour for 16 hours OR 64 sprays/day.

  • Before using for the first time, prime the pump by pressing the top firmly into a tissue until a fine mist appears. If you don’t use the spray for a couple of days, you may need to repeat this step.
  • Press the top of the dispenser to release one spray into your mouth (either under your tounge or on the inside of your cheek)
  • Wait a few seconds before swallowing.
  • Using two NRT products, such as a combination of patches and mouth spray, is more effective than using one.

Here are some things to know when you're using the mouth spray. Other things may be important as well, so ask your healthcare provider what you should know about.

If you have oesophagitis, gastritis, or peptic ulcers, using swallowed NRT can worsen these conditions. Let your doctor know if you have any worsening symptoms.

Like all medicines, NRT can cause side effects, although not everyone gets them and serious side effects are very rare. Side effects may be similar to smoking withdrawal symptoms which should disappear within 4 weeks. Often side effects improve as your body gets used to the new medicine.
