- start tab 7-14d prior to anticipated quit date


What is Varenicline MOA?

Partial agonist that binds selectively to a4b2 nicotinic Ach receptor with GREATER affinity than nicotine

- blocks nicotine from binding
- stimulates receptor but lesser degree --> still have DA release to reinforce smoking to relieve craving/withdrawal sxs


How would you describe to the patient how to use Varenicline?

Start 1 week before quit date

Plus behavior support/counseling

Longer lead-in time (starting more than 1wk prior) has shown more improved 24wk cessation rates


Varenicline Clinical Pearls

1. use for pt who have never attempted cessation AND those who have
2. pt needs MOTIVATION to quit
3. can use for up to 24wk
4. Not allowed by pilots, truckers, bus drivers, air traffic controllers**
5. C.I. in preg/breastfeeding
6. No taper required


Varenicline drug Interactions

- minimally metabolized = minimal med interactions

** w/ETOH = increased intox, aggressive behavior, amnesia


Varenicline ADRs

- dd Nausea (becomes less severe w/continued use)
- insomnia, abn dreams


What was the original BBW on Varenicline? (now removed)

Neuropsychiatric sxs and exacerbations of pre-existing psych illness (e.g. agitation, hostility, depressed mood, suicidal ideation)

Stop varenicline if serious mood or behavioral changes

Increased incidence of LBW

Associated w/peri and post-natal complications
