Which is a second-line medication for nicotine dependence?

• A. Clonidine
• B. NRT
• C. Bupropion SR
• D. Varenicline

Answer: (A)

Second-line pharmacotherapy is used when first-line options aren’t suitable or haven’t worked. Clonidine fits this category for nicotine dependence because it isn’t specifically approved as a quitting aid like nicotine replacement therapy, bupropion SR, or varenicline, which have strong trial data and official indications for smoking cessation. Clonidine helps with withdrawal by dampening central sympathetic activity, which can reduce withdrawal symptoms and cravings. It’s useful as an adjunct or after failure or intolerance of first-line therapies, but it carries risks such as sedation, dizziness, and low blood pressure, so it isn’t a first-choice option.
