The nicotine lozenge comes in the form of a hard candy, and releases nicotine as it slowly dissolves in the mouth. The lozenge is available in 2mg or 4mg doses. One lozenge is one dose, and maximum dosage should not exceed 20 lozenges per day. The lozenge is to be used over 12 weeks, and eventually, the user will consumer fewer and fewer lozenges until he or she is completely nicotine free.
Each lozenge will last about 20 to 30 minutes, and nicotine will continue to leach through the lining of the mouth for a short time after the lozenge has dissolved. The most common side effects of lozenge use are soreness of the teeth and gums, indigestion, and throat irritation.
