Some lozenge users experience soreness in the gums and teeth, irritated throat tissue, hiccups and heartburn/indigestion. These symptoms usually become more tolerable over time. The most common side effects of lozenge use are soreness of the teeth and gums, indigestion, and irritated throat. These side effects are usually short-lived and are less likely with use as directed. Do not bite into or chew the lozenge, as this will cause more nicotine to be swallowed quickly and result in indigestion and/or heartburn. Check with your doctor if you take prescription medicine for depression, asthma, diabetes or other conditions; your medications may need to be adjusted as you quit. Also, consult your doctor if you are pregnant or breastfeeding.
