4.2 Posology and method of administration
The patient should make every effort to stop smoking completely during treatment with Nicorette QuickMist.
Behavioural therapy, advice and support will normally improve the success rate.
Directions for use
If you are using Nicorette QuickMist for the first time or if you have not used the spray for 2 days, you must first prime the spray pump.
Priming
1. Point the spray safely away from you and any other adults, children or pets that are near you.
2. Press the top of the QuickMist with your index finger 3 times until a fine spray appears.
Note: priming reduces the number of sprays you may get from Nicorette QuickMist.
After priming, point the spray nozzle as close to the open mouth as possible. Press the top of the dispenser and release one spray into your mouth, avoiding the lips. Do not inhale while spraying to avoid getting spray down your throat. For best results, do not swallow for a few seconds after spraying.
The patient should not eat or drink when administering the oromucosal spray.
Care should be taken not to spray the eyes whilst administering the mouth spray.
Adults and Children over 12 years of age
Use 1 or 2 sprays when cigarettes normally would have been smoked or if cravings emerge. If after the first spray cravings are not controlled within a few minutes, a second spray should be used. If 2 sprays are required, future doses may be delivered as 2 consecutive sprays.
Most smokers will require 1-2 sprays every 30 minutes to 1 hour.
You may use up to 4 sprays per hour. Do not exceed 2 sprays per dosing episode and
64 sprays (4 sprays per hour over 16 hours) in any 24-hour period.
Each mouthspray contains at least 150 sprays.
Nicorette QuickMist should be used whenever the urge to smoke is felt or to prevent cravings in situations where these are likely to occur.
Smokers willing or able to stop smoking immediately should initially replace all their cigarettes with the Nicorette QuickMist and as soon as they are able, reduce the number of sprays used until they have stopped completely.
Smokers aiming to reduce cigarettes should use the Mouthspray, as needed, between smoking episodes to prolong smoke-free intervals and with the intention to reduce smoking as much as possible.
As soon as they are ready smokers should aim to quit smoking completely.
When making a quit attempt behavioural therapy, advice and support will normally improve the success rate. Those who have quit smoking, but are having difficulty discontinuing their Mouthspray are recommended to contact their pharmacist or doctor for advice.
So it's perfectly OK for a 12 year old to inhale 64mg of Nicotine every day? As long as big pharma is getting paid!!!
