Uses For Zyban

Bupropion is used to treat mental depression. It is also used as part of a support program to help people stop smoking. This medicine may also be used to prevent depression in patients with seasonal affective disorder, which is sometimes called winter depression.

Bupropion is sold under different brand names for different uses. If you are already taking medicine for mental depression or to help you stop smoking, discuss this with your doctor before taking bupropion. It is very important that you receive only one prescription for bupropion at a time.

This medicine is available only with your doctor's prescription.

Before Using Zyban

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of bupropion in the pediatric population. Studies with other medicines used for depression have shown that some children, teenagers, and young adults think about suicide or attempt suicide when taking these medicines. Because of this toxicity, use in children is not recommended.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of bupropion in the elderly. However, elderly patients may be more sensitive to the effects of this medicine than younger adults, and are more likely to have age-related kidney or liver problems, which may require caution and an adjustment in the dose for patients receiving bupropion.

Use bupropion only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so, may increase the chance of side effects.

This medicine should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

To lessen stomach upset, this medicine may be taken with food, unless your doctor has told you to take it on an empty stomach.

If you are taking Zyban® tablets to help you stop smoking, you may continue to smoke for about 1 week after you start using this medicine.

Precautions While Using Zyban

Your doctor will check your progress at regular visits, especially during the first few months that you take this medicine. The amount of bupropion you take may have to be adjusted to meet the needs of your condition and to help avoid unwanted effects.

Do not take bupropion with or within 14 days of taking a drug with monoamine oxidase inhibitor (MAOI) activity (e.g., isocarboxazid [Marplan®], phenelzine [Nardil®], procarbazine [Matulane®], selegiline [Eldepryl®], or tranylcypromine [Parnate®]). Do not take an MAO inhibitor within 14 days of taking bupropion. If you do, you might have convulsions (seizures).

Your blood pressure might get too high while you are using this medicine. This may cause headaches, blurred vision, and other symptoms. You might need to measure your blood pressure at home. If you think your blood pressure is getting too high, call your doctor right away.

Bupropion may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Make sure the doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. If you or your caregiver notice any of these side effects, tell your doctor right away.

Serious skin reactions can occur with this medicine. Check with your doctor right away if you have blistering, peeling, or loosening of the skin; red skin lesions; severe acne or skin rash; sores or ulcers on the skin; or fever or chills while you are using this medicine.

Drinking alcoholic beverages should be limited or avoided, if possible, while taking bupropion. This will help prevent seizures.

Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert and clearheaded.

Do not stop taking this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. This is to decrease the chance of having side effects such as agitation, anxiety, dizziness, a feeling of constant movement of self or surroundings, headache, increased sweating, nausea, trembling or shaking, trouble with sleeping or walking, or unusual tiredness when you stop the medicine.

Check with your doctor right away if you have pain or tenderness in the upper stomach; pale stools; dark urine; loss of appetite; nausea; unusual tiredness or weakness; or yellow eyes or skin. These could be symptoms of a serious liver problem.
