1. What Bupropion Sandoz is and what it is used for
Bupropion Sandoz is a medicine used to treat depression. It works on certain substances in the brain called noradrenaline and dopamine, which are related to depression.
2. What you need to know before taking Bupropion Sandoz
Do not take Bupropion Sandoz:
-
if you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6),
-
if you are taking other medicines containing bupropion,
-
if you have been diagnosed with epilepsy or have a history of seizures,
-
if you have a brain tumor,
-
if you have undergone alcohol withdrawal treatment or withdrawal from any medication associated with withdrawal risk, particularly:
-
medicines to calm, induce sleep, or relax muscles with active substance names ending in "azepam",
-
or similar sedatives,
-
if you have a severe, long-standing liver disease characterized by degeneration and thickening of liver tissue,
-
if you have an eating disorder or have had one, such as bulimia or anorexia nervosa,
-
if you have taken or have been taking other antidepressant medicines called monoamine oxidase inhibitors (MAOIs).
At least 14 days must pass between stopping certain monoamine oxidase inhibitors (called irreversible MAOIs) and starting treatment with bupropion. For some monoamine oxidase inhibitors (called reversible inhibitors), a 24-hour interval is considered sufficient. If in doubt, consult your doctor.
Warnings and precautions
Talk to your doctor before starting bupropion if:
- you regularly drink large amounts of alcohol.
- See previous section “Do not take Bupropion Sandoz” if you have undergone abrupt alcohol withdrawal.
- you have diabetes being treated with insulin or oral tablets,
- you have suffered a serious head injury or have a history of head trauma. Bupropion has been shown to cause seizures (convulsions) in 1 out of every 1000 people. This side effect is more likely in individuals in the groups mentioned above. If you have a seizure during treatment, you must stop taking bupropion. Do not take further doses and consult your doctor.
- you suffer from mood swings (bipolar disorder) or mental health problems, as bupropion could trigger an episode of this condition. Before treatment, patients should be monitored due to the risk of disorders involving episodes of elevated or agitated mood.
Before treatment, patients should be monitored due to the risk of disorders involving episodes of elevated or agitated mood.
- you are taking other antidepressant medicines, as using these together with bupropion may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Bupropion Sandoz” in this section),
- you have mild to moderate kidney or liver dysfunction.
Patients with hepatic or renal dysfunction will be monitored by the doctor for possible side effects. Do not use bupropion if you have the severe liver disease listed in the sixth point under "Do not take Bupropion Sandoz".
- you require a urine test.
Inform your doctor that you are taking bupropion, as it may interfere with urine tests used to detect other drugs.
- you have a condition called Brugada syndrome (a rare inherited condition affecting heart rhythm) or if there has been cardiac arrest or sudden death in your family.
Serious skin reactions
Serious skin reactions have been reported with bupropion, such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). Stop using bupropion and seek immediate medical attention if you notice any symptoms related to these serious skin reactions described in section 4.
If any of the above situations apply to you, talk to your doctor again before taking bupropion. Your doctor may decide to monitor you more closely or recommend an alternative treatment.
A baseline blood pressure measurement should be obtained at the start of treatment and monitored thereafter, especially in patients with pre-existing hypertension.
Bupropion has been observed to cause seizures. This adverse effect is more likely to occur in people:
- affected by a condition listed in the first three points under "Warnings and precautions" in section 2, or
- taking a medicine listed in the second of the twelve points under "Other medicines and Bupropion Sandoz" in section 2.
Risk factors should be assessed in all patients. Stop taking Bupropion Sandoz and inform your doctor if you experience seizures during treatment.
Thoughts of self-harm or suicide are associated with depression. These may increase at the beginning of treatment with antidepressant medicines, as they take time to work—usually about two weeks, but sometimes longer.
You are more likely to experience this if:
- you have previously had such thoughts,
- you are a young adult.
Studies have shown an increased risk of suicidal behavior in psychiatric patients under 25 years of age who are being treated with antidepressants.
If you have thoughts of harming yourself or suicide at any time, contact your doctor or go to hospital immediately. Talk to a close family member or friend about your depression and ask them to read this leaflet. Ask them to inform you if they think your depression is worsening or if there are changes in your behavior.
Children under 18 years
Bupropion is not recommended for this age group. In children, there is an increased risk of suicidal thoughts and attempts when treated with antidepressants.
Other medicines and Bupropion Sandoz
Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
The following medicines may affect or may be affected by bupropion, although the list is not complete. Inform your doctor if you are taking any of these medicines so your treatment can be adjusted if necessary:

If any of these situations apply, speak to your doctor immediately before taking bupropion. Your doctor will evaluate the benefits and risks of taking bupropion.
Taking Bupropion Sandoz with alcohol
Alcohol consumption (beer, wine, or spirits) is not recommended while taking bupropion. Alcohol may affect how bupropion works, and when used together, it may rarely affect your nerves or mental state. Some people report being more sensitive to alcohol while taking bupropion.
If you currently consume large amounts of alcohol, do not stop abruptly, as you may be at risk of experiencing a seizure.
Talk to your doctor about alcohol use and abstinence before taking bupropion.
Pregnancy and breastfeeding
Do not take bupropion if you are pregnant, think you may be pregnant, or plan to become pregnant unless prescribed by your doctor. Consult your doctor or pharmacist before using this medicine. Some studies have reported an increased risk of birth defects, particularly heart defects, in babies whose mothers took bupropion during pregnancy. It is not known whether this is due to bupropion use.
Components of bupropion may pass into breast milk. Consult your doctor or pharmacist if you are breastfeeding before taking bupropion.
Driving and using machines
Exercise caution before driving or operating machinery until you are fully certain that bupropion does not negatively affect your ability.
If bupropion causes dizziness or fainting, do not drive or operate tools or machinery.
Bupropion Sandoz contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet; this is essentially “sodium-free”.
3. How to take Bupropion Sandoz
Follow exactly the instructions for using this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.
The recommended dose is:
One 150 mg tablet once daily.
Your doctor may increase the dose to 300 mg once daily if your depression does not improve after several weeks.
Patients with renal or hepatic impairment
The recommended dose is one 150 mg tablet once daily if you have mild to moderate renal or hepatic impairment.
Do not use bupropion if you have severe liver disease as stated in point six "Do not take Bupropion Sandoz" in section 2.
Method of administration
Take the tablets whole, in the morning with a glass of water. The tablets may be taken with or without food. Do not take bupropion more than once a day.

Do not chew, crush, or divide the tablets, because doing so may lead to overdose, as the medicine would be released too quickly into your body. This increases the risk of adverse effects, including seizures (convulsions).
The tablet is film-coated to release the medicine slowly into your body. Occasionally, you may notice a tablet-like shell in your stools. This is the empty film coating that has passed through your body.
Duration of treatment
Your doctor will determine how long you should take bupropion.
It may take several weeks or months before you start to feel better or achieve the full effect. Speak regularly with your doctor about your symptoms to determine how long you should continue treatment.
Even if you start to feel better, your doctor may recommend continuing treatment with bupropion to prevent the return of depressive symptoms.
If you take more Bupropion Sandoz than you should
If you take more tablets than prescribed, contact your doctor immediately or go to the nearest hospital, as this may increase the risk of experiencing epileptic seizures or convulsions.
You may also contact your pharmacist immediately or call the Toxicology Information Service at: 91 562 04 20, indicating the medicine and the amount ingested.
If you forget to take Bupropion Sandoz
If you miss a dose, wait and take the next dose at the usual time. Do not take a double dose to make up for a missed dose.
If you stop taking Bupropion Sandoz
Do not stop treatment with bupropion or reduce the dose without approval from your doctor.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
4. Possible adverse effects
Like all medicines, this medicine can cause adverse effects, although not everyone will experience them.
Serious adverse effects
Inform your doctor immediately if you experience any of the following adverse effects.
Seizures or convulsions
Approximately 1 in every 1,000 people taking bupropion is at risk of having a seizure (a fit or convulsion). This risk is higher if you take more tablets than you should, if you are taking certain other medicines, or if you have a higher than usual risk of seizures. If you have any doubts, ask your doctor.
Consult your doctor if you have a seizure. Do not take any more tablets.
