Zyban Oral Warnings

Bupropion is an antidepressant used to treat a variety of conditions, including depression, other mental/mood disorders, and smoking cessation. Antidepressants can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people who take antidepressants for any condition may experience new or worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. Therefore, it is very important to talk with the doctor about the risks and benefits of antidepressant medication, even if treatment is not for a mental/mood condition.

Tell the doctor immediately if you notice new or worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed. If you are using bupropion to quit smoking, stop taking bupropion and contact your doctor immediately if you experience any of the symptoms listed above.

Zyban Oral Uses

This medication is used to treat depression. It can improve your mood and feelings of well-being. It works by helping to restore the balance of natural chemicals (neurotransmitters) in your brain.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

Bupropion may be used to treat attention-deficit hyperactivity disorder (ADHD), or to help people quit smoking by decreasing cravings and nicotine withdrawal effects. It may also be used in combination with other mood stabilizers to treat bipolar disorder (depressive phase).

How to use Zyban Oral

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 nausea occurs, you may take this drug 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 having a seizure.

This medication must be swallowed whole. Do not crush, chew or break the tablets. Doing so will destroy the slow release of the drug and may increase your risk of side effects, including seizures.

You may have trouble sleeping when you start taking bupropion. Do not take your evening dose too close to bedtime. Let your doctor know if sleeplessness becomes a problem.

Your dosage is based on your medical condition and response to therapy. Your dose should be slowly increased to limit side effects such as sleeplessness and decrease the risk of seizures.

Do not take more or less medication than prescribed. Taking more than the recommended dose will increase your risk of having a seizure. The usual maximum dose is 300-400 milligrams per day (maximum single dose 150-200 milligrams).

Do not stop taking this medication without notifying your doctor. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.

It may take 4 weeks or more before the full effects of this medication are noticed. Talk to your doctor if your condition persists or worsens.

Zyban Oral Side Effects

See also the Warning section.

Dry mouth, sore throat, nausea, vomiting, stomach/abdominal pain, flushing, headache, loss of appetite, constipation, trouble sleeping, increased sweating, strange taste in mouth, muscle/joint aches, dizziness, or blurred vision may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur: fainting, chest pain, fast heartbeat, severe headache, uncontrolled movements (tremor), unusual weight loss or gain, ringing in the ears, mental/mood changes (e.g., agitation, anxiety, hallucinations, nervousness, confusion, restlessness).

Tell your doctor immediately if any of these rare but very serious side effects occur: muscle pain/tenderness/weakness, change in the amount of urine.

This drug may rarely cause seizures. Seek immediate medical attention if you have a seizure while taking bupropion. If you have a seizure while taking bupropion, you should not take this drug again.

A severe allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a severe allergic reaction include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

An empty tablet shell may appear in your stool. This is harmless.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Promptly report any such symptoms to the doctor. However, do not stop taking this medication unless your doctor directs you to do so.

Bupropion passes into breast milk. Because of the potential risk to the infant, breast-feeding is not recommended while using this drug.
