1. What is Bupropion SUN and what is it used for

Bupropion is a medicine prescribed by your doctor to treat depression. It is thought to work on certain substances in the brain called noradrenalineand dopamine.

2. What you need to know before you take Bupropion SUN

• If you are taking other medicines containing bupropion
• If you have been diagnosed with epilepsy or have a history of seizures
• If you have, or have had, any eating disorder (e.g. bulimia or anorexia nervosa)
• If you have a brain tumor
• If you are taking large amounts of alcohol and have started, or are about to start, alcohol withdrawal
• If you have severe liver disease
• If you have stopped taking sedatives, or are about to stop taking them while taking bupropion (see also section 2 "Do not take Bupropion SUN")
• If you are taking or have taken in the last two weeks other medicines for depression called monoamine oxidase inhibitors(MAOIs)

If you are in any of these situations, tell your doctor immediately and do not take bupropion.

Warnings and precautions

Consult your doctor or pharmacist before starting to take bupropion.

Brugada Syndrome

If you have a condition called Brugada Syndrome (a rare inherited condition that affects the heart rhythm) or if there has been a cardiac arrest or sudden death in your family.

Children and adolescents

Bupropion is not recommended for the treatment of children under 18 years of age.

In patients under 18 years, there is an increased risk of suicidal thoughts and attempts when treated with antidepressants.

Adults

Tell your doctor before starting to take bupropion:

• If you regularly drink a lot of alcohol
• If you have diabetes that is being treated with insulin or oral tablets
• If you have had a severe head injury or have had a head trauma in the past.

It has been observed that bupropion can cause seizures (convulsions) in approximately 1 in 1,000 people. This side effect is more likely to occur in people who are in the situations mentioned above. If you have a seizure while taking bupropion, stop treatment. Do not take it again and visit your doctor.

• If you have bipolar disorder (very pronounced mood swings), bupropion may cause episodes of this illness
• If you are taking other medicines for depression, the use of these medicines together with bupropion may cause serotonin syndrome, a potentially life-threatening condition (see "Other medicines and Bupropion SUN" in this section)
• If you have any liver or kidney disease, the likelihood of suffering from side effects is higher

If you are in any of these situations, consult your doctor before taking bupropion, who may decide to monitor you more closely or recommend another treatment.

Suicidal thoughts and worsening of your depression

If you are depressed, you may sometimes have thoughts of harming yourself or suicide. These can increase at the start of treatment with antidepressants, as all these medicines take time to work, which is usually a few weeks, but sometimes can be longer.

This is more likely to happen:

• If you have previously had thoughts of suicide or self-harm
• If you are a young adult. There is information from clinical trials that shows an increased risk of suicidal behavior in adults under 25 with psychiatric disorders who were being treated with some antidepressants.

If you have thoughts of self-harm or suicide at any time, consult your doctor or go to the hospital immediately.

It may be helpful for you to explain to a family member or close friendthat you are depressed or have anxiety disorders, and ask them to read this leaflet. You can also ask them to tell you if they think your depression or anxiety is getting worse, or if they are concerned about changes in your behavior.

Other medicines and Bupropion SUN

Stop treatment with bupropion and inform your doctor if you are taking or have taken antidepressant medicines called monoamine oxidase inhibitors(MAOIs) during the last two weeks (see also section 2 "Do not take Bupropion SUN").

Tell your doctor or pharmacist that you are using, have recently used, or might use any other medicines, including those obtained without a prescription. The doctor may change the dose of bupropion or suggest a change in the other medicines.

Some medicines interact with bupropion. Some of them can increase the likelihood of having seizures or convulsions, and others can increase the risk of having other side effects. The following are some examples, although the list is not complete.

May increase the possibility of having seizures

• if you take other medicines for depression or other mental illnesses
• if you take theophylline used to treat asthma or other lung diseases
• if you take tramadol, a strong pain reliever
• if you have been taking sedatives, or if you are going to stop taking them while taking bupropion (see also section 2 "Do not take Bupropion SUN")
• if you take medicines to treat malaria (such as mefloquine or chloroquine)
• if you take stimulants or other medicines to control your weight or appetite
• if you use corticosteroids (by mouth or by injection)
• if you use antibiotics called quinolones
• if you use certain antihistamines that can cause drowsiness
• if you use medicines to treat diabetes.

If you are in any of these situations, inform your doctor immediately before taking bupropion. Your doctor will assess the risks and benefits of taking this medicine.

May increase the possibility of having other side effects

• if you take other medicines for depression (amitriptyline, fluoxetine, paroxetine, citalopram, escitalopram, venlafaxine, dosulepin, desipramine, or imipramine) or other mental illnesses (clozapine, risperidone, thioridazine, or olanzapine). Bupropion may interact with some medicines used to treat depression and may experience changes in mental status (e.g., agitation, hallucinations, coma) and other side effects such as body temperature above 38°C, increased heart rate, unstable blood pressure, exaggerated reflexes, muscle stiffness, lack of coordination, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea)
• if you take antiparkinsonian medicines (levodopa, amantadine, or orphenadrine)

• if you take medicines that affect your body's ability to eliminate bupropion (carbamazepine, phenytoin, valproate)

• if you take some medicines used to treat cancer (such as cyclophosphamide or ifosfamide)

?

• if you take any beta-blocker medicine (metoprolol)
• if you take medicines to treat heart rhythm disorders (propafenone, flecainide)

?

If you are in any of these situations, inform your doctor immediately before taking bupropion.

Bupropion SUN may be less effective

• if you take ritonavir or efavirenz, medicines to treat HIV (AIDS) infection.

Tell your doctor if you are taking any of these medicines. Your doctor will check if bupropion is working properly in you. It may be necessary to increase the dose or change to another treatment for your depression. Do not increase the dose of bupropion unless your doctor advises you to, as this can increase the risk of having side effects, including seizures.

Bupropion SUN may make other medicines less effective

• If you take tamoxifen used to treat cancer.

Tell your doctor if you are in this situation. It may be necessary to change your treatment for depression.

• If you take digoxin for your heart.

Tell your doctor if you are in this situation. The doctor may consider adjusting the dose of digoxin.

Using Bupropion SUN and alcohol

Alcohol can affect how bupropion works and, when taken together, can rarely affect your nerves or mental state. Some people have noticed that they are more sensitive to alcohol during treatment with bupropion. The doctor may recommend that you do not drink alcohol (beer, wine, spirits) or that you drink very small amounts while taking bupropion. If you currently drink a lot of alcohol, do not stop suddenly, as you may be at risk of having a seizure.

Consult your doctor about alcohol consumptionbefore starting treatment with bupropion.

Effect on urine tests

Bupropion may interfere with some urine tests used to detect other medicines or substances. If you need a urine test, tell your doctor or hospital that you are taking bupropion.

Pregnancy and breastfeeding

Do not take bupropion if you are pregnant, think you may be pregnant, or plan to become pregnant unless your doctor prescribes it. Consult your doctor or pharmacist before using this medicine. Some studies, not all, have reported an increased risk of birth defects, particularly heart defects, in babies whose mothers were taking bupropion. It is not known if this is due to the use of bupropion.

The components of Bupropion may pass into breast milk. Consult your doctor or pharmacist before taking Bupropion.

Driving and using machines

Do not drive or use tools or machines if bupropion makes you feel dizzy or drowsy.

3. How to take Bupropion SUN

Follow exactly the administration instructions of this medicine given by your doctor or pharmacist. The recommended doses are included below, but your doctor will advise you on the dose that is right for you. If in doubt, consult your doctor or pharmacist again.

It may take some time before you start to feel better.The medicine takes time to work fully, which can be weeks or months. When you start to feel better, your doctor may advise you to continue treatment with bupropion to prevent depression from coming back.

What dose to take

The usual recommended dose in adults is one 150 mg tablet per day.

If after several weeks you do not start to feel better, your doctor may increase the dose to 300 mg per day.

Take the bupropion tablets in the morning. Do not take bupropion more than once a day.

The tablet is covered by a film that slowly releases the medicine in your body. Sometimes you may notice that a kind of tablet appears in your stool. This is the empty coating that has passed through your intestine.

Swallow the tablets whole. Do not chew, crush, or divide them, as this can lead to an overdose due to the rapid release of the medicine in your body, increasing the likelihood of having side effects, including seizures.

Some people may maintain a dose of one 150 mg tablet per day throughout treatment. Your doctor may prescribe this dose in patients with liver or kidney problems.

Duration of treatment

Consult your doctor, who will indicate the duration of treatment with bupropion in agreement with you. It may take several weeks or months before you notice any improvement. Keep your doctor informed about your symptoms regularly so that they can decide on the duration of treatment. Although you may start to feel better, your doctor may recommend continuing treatment with bupropion to prevent the symptoms of depression from coming back.
