Cytisine works by reducing the urge to smoke.  It attaches to some of the same nerve receptors in the brain as nicotine. This leads to fewer nicotine withdrawal symptoms and lessens the feeling of satisfaction from nicotine.

Do not take cytisine if you have uncontrolled high blood pressure or atherosclerosis.

Check with your healthcare provider if you have high blood pressure or any heart conditions before use.
