unsuccessful attempts; it’s rare to succeed on your first try.
Both counseling and medications have been shown to help
smokers quit. Some medications provide nicotine to help
reduce cravings and limit withdrawal symptoms, which include
irritability and anxiety. These medications are available over the
counter in the form of patches, gum and lozenges.
Prescription medications such as bupropion (Zyban or
Wellbutrin) and varenicline (Chantix) are also used to support
smokers’ attempts to stop. Neither these medications nor the
nicotine-replacement therapies have been tested in the context
of diving. But as with other medications, it is a good idea to take
any drug for a significant period (30 days, for example) before
diving with it. This helps minimize the risk of unexpected
side effects occurring for the first time underwater; it also
ensures the dosage adequately treats the symptoms of nicotine
withdrawal. Serious side effects with bupropion and varenicline
are not common, but they are possible.
If you experience any unusual symptoms during a dive,
end the dive and discuss them with your doctor before diving
again. The doctor may be able to work with you to find a
more suitable medication.
