6. Contents of the pack and additional information.

Zarelis Retard contains the active substance venlafaxine.

Zarelis Retard 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 action of antidepressants is not fully understood, but they may help increase levels of serotonin and norepinephrine in the brain.

Zarelis Retard is a treatment for adults with depression. Treating depressive and anxiety disorders properly is important to help you feel better. If left untreated, your condition may not go away or may worsen and become harder to treat.

Do not take Zarelis Retard

• If you are allergic to venlafaxine or any of the other ingredients of this medication (described in section 6).
• If you are also taking or have taken within 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 Zarelis Retard may produce severe or potentially fatal side effects. Additionally, you should wait at least 7 days after stopping Zarelis Retard before taking any IMAO irreversible (see also the section called "Other medications and Zarelis Retard" and the information in that section on "Serotonin syndrome").

Warnings and precautions

Speak with your doctor or pharmacist before starting to take Zarelis Retard

• If you are using other medications that, taken together with Zarelis Retard, may increase the risk of developing Serotonin syndrome (see the section "Other medications and Zarelis Retard").
• If you have a swallowing disorder, stomach or intestinal disorder that reduces your ability to swallow or pass food through normal intestinal movements.
• 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 an abnormal heart rhythm.
• 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 ecchymoses or tendency to bleed easily) or if you are using other medications that may increase the risk of bleeding, e.g., warfarin (used to prevent blood clots) or if you are pregnant (see section "Pregnancy and breastfeeding").
• If you have a history of, or if someone in your family has had, mania or bipolar disorder (feeling overexcited or euphoric).
• If you have a history of aggressive behavior.

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

Do not drink alcohol during treatment with Zarelis Retard, as it may cause extreme fatigue and unconsciousness. Taking it with certain medications and/or alcohol may worsen the 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 an anxiety disorder, you may sometimes have thoughts of harming yourself or committing suicide. These suicidal thoughts may increase when starting to take antidepressants, as all these medications take time to take effect, usually two weeks but sometimes longer. These thoughts may also occur when reducing your dose or during the end of treatment with Zarelis Retard.

It is more likely to happen:

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

If you have thoughts of harming yourself or committing suicide at any time, contact your doctor or go to the hospital directly.

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 dental decay (caries). Therefore, you should take care with your dental hygiene.

Diabetes

Your blood glucose levels may be altered due to Zarelis Retard. Therefore, you may need to adjust the dose of your diabetes medication.

Sexual problems

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

Children and adolescents

Zarelis Retard 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 behavior, suicidal thoughts, and hostility (predominantly aggression, confrontational behavior, and irritability) when taking this type of medication. However, the doctor who prescribes it may prescribe it to patients under 18 years old when they decide it is the best option for the patient. If the doctor who prescribes it has prescribed it to a patient under 18 years old and wants 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 who are taking venlafaxine. Additionally, the long-term effects of this medication on growth, maturation, and cognitive and behavioral development have not yet been demonstrated.

Other medications and Zarelis Retard

Inform your doctor or pharmacist if you are using, have used recently, or may use any other medication.

Your doctor should decide if you can take Zarelis Retard 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 and Parkinson's disease, should not be used with venlafaxine. Inform your doctor if you have taken these medications within the last 14 days (IMAO: see section "What you need to know before starting to take Zarelis Retard").
• Serotonin syndrome:

Serotonin syndrome, a potentially fatal state, or Malignant Neuroleptic Syndrome (MNS) (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 severe pain)
• Medications containing methylene blue (used to treat elevated methemoglobin levels 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 auditory, visual, or perceptual hallucinations, delusions, unusual distrust, confused thinking, and withdrawal.

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, vomiting.

Serotonin syndrome, in its most severe form, may resemble Malignant Neuroleptic Syndrome (MNS). The symptoms and signs of MNS may include a combination of fever, rapid heart rate, sweating, severe muscle rigidity, confusion, increased levels of muscle enzymes (determined in blood).

Inform your doctor immediately or go to the hospital nearest to you if you think you are suffering from Serotonin syndrome.

You should inform your doctor if you are taking medications that affect heart rhythm. Examples of these medications include:

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

The following medications may also interact with Zarelis Retard 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 (antifungal medications).
• Haloperidol or risperidone (used to treat psychiatric disorders).
• Metoprolol (a beta-blocker used to treat high blood pressure and heart problems).

Use of Zarelis Retard with food, drinks, and alcohol

Venlafaxine should be taken with food (see section 3 "How to take Zarelis Retard").

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

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist before taking this medication. You should only take Zarelis Retard after discussing with your doctor the possible benefits and risks for the unborn baby.

Make sure your midwife and/or doctor know that you are using Zarelis Retard. When taking similar medications (called serotonin reuptake inhibitors: ISRS) during pregnancy, there may be an increased risk of a serious condition called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe faster and appear blue. These symptoms usually start within the first 24 hours after birth. If this happens to you, you should contact your doctor and/or midwife immediately.

If you take Zarelis Retard in the final stages of pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Zarelis Retard to be able to advise you.

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

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

If you forgot to take Zarelis Retard

If you have missed a dose, take it as soon as you remember. However, if it is already time for your next dose, skip the missed dose and take only one dose as usual. Do not take a double dose to compensate for a missed dose. Do not take more than the daily dose of Zarelis Retard prescribed by your doctor in a day.

If you interrupt treatment with Zarelis Retard

Do not stop taking your treatment or reduce the dose without consulting your doctor, even if you feel better. If your doctor believes you no longer need Zarelis Retard, they may ask you to reduce the dose gradually before stopping treatment completely. It is known that adverse effects occur when people stop using this medication, especially when it is stopped suddenly or if the dose is reduced very quickly. Some patients may experience symptoms such as suicidal thoughts, aggression, fatigue, dizziness, instability, headaches, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, confusion, ringing in the ears, tingling, or, in rare cases, electric shock sensations, weakness, sweating, seizures, or symptoms similar to the flu, vision problems, and increased blood pressure (which may cause headaches, dizziness, ringing in the ears, sweating, etc.).

Your doctor will advise you on how to gradually stop treatment with Zarelis Retard. This may take several weeks or months. In some patients, the interruption may need to be produced very gradually over periods of several months or more. If you experience any of these or other symptoms that bother you, consult your doctor for further advice.

If you have any other doubts about the use of this medication, ask your doctor or pharmacist.

Like all medicines, this medicine can cause side effects, although not everyone will experience them.
