Kirkland Signature Quit4 is a nicotine replacement therapy gum designed to help adults quit smoking. Each piece contains 4mg of nicotine polacrilex, formulated for individuals who smoke their first cigarette within 30 minutes of waking up. This package contains 380 pieces total, packaged as two boxes of 190 pieces each in original flavor.

The gum works by reducing withdrawal symptoms and nicotine cravings associated with quitting smoking. Users chew slowly until a peppery tingle occurs, then park the gum between cheek and gum, repeating this chew-and-park cycle for approximately 30 minutes per piece. The recommended 12-week program starts with one piece every 1-2 hours during weeks 1-6, gradually reducing frequency to every 2-4 hours during weeks 7-9, and every 4-8 hours during weeks 10-12. Maximum daily use is 24 pieces.

Active ingredient is nicotine polacrilex 4mg per piece. Inactive ingredients include acesulfame potassium, calcium carbonate, carnauba wax, D&C yellow no. 10, flavors, gum base, sodium bicarbonate, sodium carbonate anhydrous, sorbitol, and talc. Users should avoid eating or drinking 15 minutes before and during use. Consult a healthcare provider before use if pregnant, breastfeeding, or have heart disease, high blood pressure, stomach ulcers, diabetes, or seizure history.
