Many of the side effects occur within the first 3 to 4 weeks after starting treatment. Initially there may be slight irritation of the throat and increase of saliva. Excessive swallowing of saliva containing nicotine may cause hiccups.
Those with a tendency to indigestion may suffer initially from indigestion or heartburn. Gentler sucking of the lozenge may overcome these effects.
Those who smoked but did not inhale may experience nausea, faintness and headache.
Side effects such as dizziness and headache and insomnia may be experienced as nicotine intake is lowered.
Other side effects may include wind and dry mouth. Less common are palpitations and a change in heart rhythm. Cold sores have been reported but it is unclear whether this is due to the lozenge. Tell the physician or pharmacist if the patient noticed any other effect that might be caused by using the lozenge.
