Do not smoke during treatment with the nicotine inhaler because of the risk of nicotine overdose.
Do not use the nicotine inhaler for longer than 6 months if you have stopped smoking because continuing use of nicotine in any form can be harmful and addictive.
Nicotine should not be used in pregnancy. If there is a possibility you might become pregnant, you may want to use some type of birth control. If you think you may have become pregnant, stop taking this medicine immediately and check with your doctor.
Nicotine products must be kept out of the reach of children and pets. Even used nicotine inhaler cartridges contain enough nicotine to cause serious harm in children. If a child chews on or swallows a cartridge, contact your doctor or poison control center at once.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
