This medication is typically used to help quit smoking. It requires several days to take effect.

Instructions

This medication is typically used twice a day. However, your doctor or pharmacist may have suggested a different schedule that is more appropriate for you. Take it regularly and continuously to maintain its beneficial effects.

Important: Follow the instructions on the label. Do not use more of this product, or more often, than prescribed. If you forget a dose, take it as soon as you remember -- unless it is almost time for your next dose. In that case, skip the missed dose. Do not double the next dose to catch up.

It is preferable to take this medication after eating and with a full glass of water to decrease nausea. This medication may change the way you react to alcohol.
