Uses
This
medication is used in combination with a stop-
smoking program (e.g., support group,
counseling) to help you
quit smoking.
Bupropion can decrease your
nicotine withdrawal symptoms (e.g., irritability,
anxiety, restlessness) and your urge to smoke. Quitting
smoking decreases your risk of
heart and
lung disease, as well as
cancer.
This medication belongs to a class of
medications known as
antidepressants. It is not known exactly how bupropion works to reduce
smoking urges. It may work by restoring the balance of certain natural chemicals (neurotransmitters) in the
brain.
Discuss the risks and benefits of this medication, as well as other ways to
quit smoking (such as nicotine replacement treatment), with your doctor.
How to use Zyban
Read the
Medication Guide and, if available, the Patient Information Leaflet provided by your
pharmacist before you start using
bupropion and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.
Take this medication by
mouth, usually twice daily with or without food. If
stomachupset occurs, take with food. It is important to take your doses at least 8 hours apart or as directed by your doctor to decrease your risk of
seizure.
You may have
trouble sleeping when you start taking this drug.
Do not take your evening dose too close to
bedtime.
Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects, including
seizures. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
Your dosage is based on your medical condition and response to therapy. Your dose may be slowly increased to limit side effects. Do not take more or less medication than prescribed. Do not take more than 150 milligrams in a single dose. Do not take more than 300 milligrams per day. Taking more than the recommended dose of this medication may increase your risk of having a seizure.
It is recommended that you do not try to
quit smoking until you have been taking bupropion for 1 week so that the drug can reach a high enough level in your
blood. Set a date for quitting, and
stop smoking sometime in the second week of taking the drug.
If necessary, this medication may be combined with nicotine patches or gum to help you
quit smoking. Ask your doctor for more information. The combination of nicotine and this medication may increase your
blood pressure. Your doctor may need to monitor your
blood pressure closely. Do not smoke at any time if using any nicotine products with this drug. Too much nicotine can cause serious side effects.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day.
Tell your doctor if you are not able to
stop smoking after 7 to 12 weeks on this medication.
