bupropion extended release
How does this medication work? What will it do for me?
Bupropion belongs to the family of medications known as antidepressants. It is used to treat major depression and to prevent autumn-winter seasonal depression. It is believed to work by affecting the balance of noradrenaline and dopamine, chemicals that occur naturally in the brain and affect mood.
For the treatment of depression, the full effects of the medication may not be seen until after several weeks of treatment.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Drowsiness/reduced alertness: Bupropion may affect the mental or physical abilities needed to drive or operate machinery. Avoid driving, operating machinery, or performing other hazardous tasks until you have determined how this medication affects you.
Glaucoma: This medication may cause the symptoms of glaucoma (increased pressure in the eye) to become worse. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Report any changes in vision to your doctor as soon as possible while you are taking this medication.
Heart disease: It is not known whether bupropion is safe for use by people with a recent history of heart attack or unstable heart disease. Bupropion may cause increases in blood pressure. If you have heart problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Identical medications: Wellbutrin® XL, Wellbutrin® SR, Zyban®, and several other medications contain the same active ingredient (bupropion). If you are taking one of these medications, do not take the other or any other product containing bupropion, as the risk of seizures increases with an increased dosage. To reduce the risk of seizures, the total daily dose of this medication should not be greater than 300 mg.
Kidney function: Bupropion is removed from the body by the kidneys. Decreased kidney function can cause this medication to build up in the body, causing side effects. If you have kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Bupropion is removed from the body by the liver. Decreased liver function can cause this medication to build up in the body, causing side effects. If you have liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
This medication may also cause a decrease in liver function. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Seizure risk: This medication may increase the risk of seizures. If you are at risk of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Things which increase the risk of seizures include:
- addiction to cocaine, stimulants (e.g., amphetamines), or opiates (e.g., morphine, codeine, oxycodone)
- diabetes treated with oral medications or insulin
- excessive alcohol use
- history of head trauma or seizures (including epilepsy)
- severe liver problems
- tumours of the brain or spinal cord
- use of other medications that make seizures more likely (e.g., antipsychotics, antidepressants, lithium, theophylline, steroids)
- use of over-the-counter stimulants or appetite suppressants
Stopping the medication: Stopping this medication suddenly may lead to side effects. If you are thinking of stopping the medication, check with your doctor first.
Serotonin syndrome: Severe reactions are possible when bupropion is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors, other medications used to treat depression. Similar effects occur when too much bupropion is taken or is allowed to build up in the body. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, and changes in mental state including delirium and agitation. These reactions should be treated as a medical emergency and immediate medical treatment should be obtained as coma and death are possible.
Suicidal or agitated behaviour, or other behaviour changes: Especially in the first few weeks or when doses are changed, a small number of people may feel worse instead of better when taking this medication. People may feel agitated (restless, anxious, aggressive, emotional, and feeling not like themselves), or they may want to hurt themselves or others. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. Your doctor will monitor you closely for these side effects while you are taking this medication.
Pregnancy: This medication should not be taken during pregnancy unless the benefits outweigh the risks. It has been reported that babies born to pregnant women who have taken medications of this kind during pregnancy may be adversely affected. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: Bupropion passes into breast milk. Because this medication presents risks to breast-feeding infants, a decision should be made whether to discontinue breast-feeding or to discontinue bupropion, taking into account the importance of the medication to the mother. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using bupropion have not been established for children and adolescents under 18 years of age. The use of this medication in children under 18 may cause behavioural and emotional changes, such as suicidal thoughts and behaviour.
Seniors: Because this medication is removed from the body by the kidneys and liver, seniors may be at an increased risk of side effects, including seizures, if they use this medication. If you are over 65, discuss with your doctor whether any special monitoring is required.
