Dobupal is an antidepressant that belongs to a group of medications called serotonin and norepinephrine reuptake inhibitors (SNRIs). This group of medications is used to treat depression and other conditions such as anxiety disorders. The exact mechanism of how antidepressants work is not fully understood, but they may help increase levels of serotonin and norepinephrine in the brain.

Dobupal is a treatment for adults with depression. Properly treating depressive disorders is important to help you feel better. If left untreated, your condition may not go away or may worsen and become more difficult to treat.

Do not take Dobupal

• If you are allergic to venlafaxine or any of the other ingredients in this medication (listed in section 6).
• If you are also taking or have taken in the last 14 days any medication known as an irreversible monoamine oxidase inhibitor (IMAO), used to treat depression or Parkinson's disease. Taking an IMAO irreversible with Dobupal may cause severe or potentially fatal side effects. You must also wait at least 7 days after stopping Dobupal before taking any IMAO (see also the section "Use of other medications" and the information in that section on "Serotonin Syndrome").

Warnings and precautions

Consult your doctor or pharmacist before starting to take Dobupal:

• If you are taking other medications that, when taken with Dobupal, may increase the risk of developing serotonin syndrome (see section "Taking Dobupal with other medications").
• If you have eye problems, such as certain types of glaucoma (increased eye pressure).
• If you have a history of high blood pressure.
• If you have a history of heart problems.
• If you have been informed that your heart rhythm is altered.
• If you have a history of seizures (convulsions).
• If you have a history of low sodium levels in the blood (hyponatremia).
• If you have a history of bleeding disorders (tendency to develop petechiae or tendency to bleed easily), or if you are pregnant (see section Pregnancy, breastfeeding, and fertility), or if you are taking other medications that may increase the risk of bleeding, such as warfarin (used to prevent blood clots).
• If you have a history of mania or bipolar disorder (feeling overexcited or euphoric).
• If you have a history of aggressive behavior.

Dobupal may cause restlessness or difficulty sitting or staying still during the first few weeks of treatment. You should consult your doctor if this occurs.

Some medications in the group to which Dobupal belongs (called ISRS/IRSN) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms persist after stopping treatment.

Do not drink alcohol during treatment with Dobupal, as it may cause extreme fatigue and unconsciousness. Taking it with certain medications and/or alcohol may worsen symptoms of depression and other conditions, such as anxiety disorders.

Thoughts of suicide and worsening of depression or anxiety disorder

If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or committing suicide. These thoughts may increase when starting to take antidepressants, as all these medications take time to work, usually two weeks or more. These thoughts may also occur when your dose is reduced or during the interruption of treatment with Dobupal.

It is more likely to happen:

• If you have had previous thoughts of suicide or self-harm.
• If you are a young adult. Clinical trial information has shown an increased risk of suicidal behavior in young adults (less than 25 years old) with psychiatric disorders treated with antidepressants.

Immediately contact your doctor or go to the nearest hospital emergency room if you have thoughts of harming yourself or committing suicide at any time.

You may find it helpful to tell a close family member or friend that you are depressed or have an anxiety disorder, 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.

Dry mouth

Dry mouth has been reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay (caries). Therefore, you should take good care of your dental hygiene.

Diabetes

Your blood glucose levels may be affected by Dobupal. Therefore, your diabetes medication doses may need to be adjusted.

Children and adolescents

Dobupal should not be used normally in the treatment of children and adolescents under 18 years old. Additionally, you should know that in patients under 18 years old, there is a higher risk of adverse effects such as suicidal thoughts, suicidal attempts, and hostility (predominantly aggression, confrontational behavior, and irritability) when taking this type of medication. However, your doctor may prescribe this medication to patients under 18 years old when they decide what is best for the patient. If your doctor has prescribed this medication to a patient under 18 years old and you want to discuss this decision, please return to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen in these patients under 18 years old while taking Dobupal. Furthermore, the long-term safety in relation to growth, maturation, and cognitive and behavioral development has not been demonstrated.

Taking Dobupal with other medications

Inform your doctor or pharmacist if you are using or have used recently or may need to use any other medication. Your doctor must decide if you can take Dobupal with other medications.

Do not start or stop taking any medication, including those sold without a prescription, natural remedies, and herbal products, before checking with your doctor or pharmacist.

• Irreversible monoamine oxidase inhibitors used to treat depression or Parkinson's diseaseshould not be taken with Dobupal. Tell your doctor if you have taken any of these medications in the last 14 days. (IMAO: See section "What you need to know before starting to take Dobupal")

• Serotonin syndrome:

A potentially fatal state, or reactions similar to the Neuroleptic Malignant Syndrome (NMS) (see section "Possible side effects") may occur with treatment with venlafaxine, particularly when taken with other medications. Examples of these medications include:

• Triptans (used for migraines)
• Other medications for treating depression, such as ISRN, ISRS, tricyclic antidepressants, or medications containing lithium
• Medications containing amphetamines (used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity)
• Medications containing the antibiotic linezolid (used to treat infections)
• Medications containing moclobemide, an IMAO (used to treat depression)
• Medications containing sibutramine (used for weight loss)
• Medications containing opioids (e.g., buprenorphine, tramadol, fentanyl, tapentadol, pethidine, or pentazocine) (used to treat severe pain)
• Medications containing dextromethorphan (used to treat cough)
• Medications containing methadone (used to treat opioid addiction or to treat severe pain)
• Medications containing methylene blue (used to treat high levels of methemoglobin in the blood)
• Products containing St. John's Wort (also known as "Hypericum perforatum", a natural or herbal remedy used to treat mild depression)
• Products containing tryptophan (used for problems such as sleep and depression)
• Antipsychotics (used to treat a disorder with symptoms such as hearing, seeing, or feeling things that do not exist, false beliefs, unusual suspicion, unclear thinking, and tendency to withdraw)

The signs and symptoms of serotonin syndrome may include a combination of the following:

Restlessness, hallucinations, loss of coordination, rapid heartbeat, increased body temperature, rapid changes in blood pressure, hyperactive reflexes, diarrhea, coma, nausea, and vomiting.

In its most severe form, serotonin syndrome may resemble Neuroleptic Malignant Syndrome (NMS). The signs and symptoms of NMS may include a combination of fever, rapid heartbeat, sweating, severe muscle rigidity, confusion, and increased muscle enzymes (determined by a blood test).

Immediately inform your doctor or go to the nearest hospital emergency room if you think you are experiencing serotonin syndrome.

Inform your doctor if you are taking medications that may affect your heart rhythm.

Examples of these medications include:

• Antiarrhythmics such as quinidine, amiodarone, sotalol, or dofetilide (used to treat abnormal heart rhythm)
• Antipsychotics such as thioridazine (see also "Serotonin syndrome" above)
• Antibiotics such as erythromycin or moxifloxacin (used to treat bacterial infections)
• Antihistamines (used to treat allergies)

The following medications may interact with Dobupal and should be used with caution. It is especially important to mention to your doctor or pharmacist if you are taking medications that contain:

• Ketoconazole (an antifungal medication)
• Haloperidol or risperidone (for treating psychiatric disorders)
• Metoprolol (a beta-blocker for treating high blood pressure and heart problems)

Taking Dobupal with food, drinks, and alcohol

Dobupal should be taken with food (see section 3 "How to take Dobupal")

Do not drink alcohol during treatment with Dobupal. Taking it with alcohol may cause extreme fatigue and unconsciousness, and worsen symptoms of depression and other conditions, such as anxiety disorders.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication. You should only take Dobupal after discussing the possible benefits and risks for the unborn child with your doctor.

If you take Dobupal in the final stages of pregnancy, there may be a higher risk of excessive vaginal bleeding after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Dobupal so they can advise you. When taken during pregnancy, similar medications (ISRS) may increase the risk of a severe condition in newborns, called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe faster and turn blue. These symptoms usually start within the first 24 hours after the baby's birth. If this happens to your baby, you should immediately contact your midwife and/or doctor.

If you are taking this medication during pregnancy, in addition to breathing problems, other symptoms that your baby may have when born are feeding problems. If your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife, who can advise you.

Dobupal passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss the case with your doctor, and they will decide whether you should stop breastfeeding or stop taking this medication.

Driving and operating machinery

Do not drive or operate tools or machines until you know how this medication affects you.
