6. Additional Informationl

Venlafaxina Retard Vir 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. It is believed that people who are depressed and/or anxious have lower levels of serotonin and noradrenaline in the brain. The exact mechanism of how antidepressants work is not fully understood, but they may help increase the levels of serotonin and noradrenaline in the brain.

Venlafaxina Retard Vir is a treatment for adults with depression. Venlafaxina Retard Vir is also

a treatment for adults with the following anxiety disorder: social anxiety disorder (fear or avoidance of social situations). Treating depressive and anxiety disorders properly is important to help you feel better. If left untreated, your condition may not disappear or may worsen and become more difficult to treat.

Do not take Venlafaxina Retard Vir

• If you are allergic (hypersensitive) to venlafaxine or to any of the other components of Venlafaxina Retard Vir.
• 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 other medications, such as Venlafaxina Retard Vir, may produce severe or potentially fatal adverse effects. Additionally, you must wait at least 7 days after stopping Venlafaxina Retard Vir before taking any IMAO irreversible (see also the sections “Serotonin syndrome” and “Use of other medications”).

Be especially careful with Venlafaxina Retard Vir

• If you use other medications that, taken at the same time as Venlafaxina Retard Vir, may increase the risk of developing serotonin syndrome (see the section “Use of 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 a history of seizures (convulsions).
• If you have a history of low sodium levels in the blood (hyponatremia).
• If you have a tendency to develop bleeding or bruising easily (history of bleeding disorders), if you are using other medications that may increase the risk of bleeding, or if you are pregnant (see “Pregnancy”).
• If your cholesterol levels increase.
• 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.

Venlafaxina Retard Vir may cause restlessness or difficulty sitting or staying still. You should consult your doctor if this occurs.

If you can apply any of these situations, consult your doctor before taking Venlafaxina Retard Vir.

Do not drink alcohol during treatment with Venlafaxina Retard Vir, 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. This may be more likely to happen:

• If you have previously had 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.

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 tooth decay. Therefore, you should take care of your dental hygiene.

Use in children and adolescents under 18 years of age

Venlafaxina Retard Vir should not be used normally in the treatment of children and adolescents under 18 years of age. Additionally, you should know that in patients under 18 years of age, there is a higher risk of adverse effects such as suicidal thoughts, suicidal ideation, and hostility (predominantly aggression, confrontational behavior, and irritability) when taking this type of medication. However, the doctor who prescribes Venlafaxina Retard Vir may prescribe it to patients under 18 years of age when they decide it is the best option for the patient. If the doctor who prescribes Venlafaxina Retard Vir has prescribed it to a patient under 18 years of age 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 of age who are taking Venlafaxina Retard Vir. Additionally, the long-term effects of Venlafaxina Retard Vir have not yet been demonstrated in terms of safety and those related to growth, maturity, and cognitive and behavioral development.

If your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife who can advise you.

If you take Venlafaxina Retard Vir in the final stages of pregnancy, there may be a higher risk of heavy vaginal bleeding after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Venlafaxina Retard Vir so they can advise you.

Breastfeeding

Venlafaxina Retard 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 if you should stop breastfeeding or stop taking Venlafaxina Retard Vir.

If you take more Venlafaxina Retard Vir than you should

Call your doctor or pharmacist immediately if you take more than the prescribed dose of Venlafaxina Retard Vir. You can also contact the Toxicology Information Service, phone 91562 04 20, indicating the medication and the amount taken.

Overdose can put your life at risk, especially when taken with certain medications and/or alcohol (see Taking Venlafaxina Retard Vir with other medications).

The symptoms of a possible overdose may include palpitations, changes in alertness (ranging from drowsiness to coma), blurred vision, seizures or attacks, and vomiting.

If you forget to take Venlafaxina Retard Vir

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 more than the daily dose of Venlafaxina Retard Vir prescribed to you in a day.

If you interrupt treatment with Venlafaxina Retard Vir

Do not stop taking your treatment or reduce the dose without consulting your doctor, even if you feel better. If your doctor thinks you no longer need Venlafaxina Retard Vir, they may ask you to gradually reduce the dose before stopping treatment completely.

Some patients may experience symptoms such as fatigue, dizziness, lack of stability, headache, 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 flu-like symptoms.

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

Like all medications, Venlafaxina Retard Vir may cause side effects, although not everyone will experience them.

Do not worry if you see a small tablet in your stool after taking Venlafaxina Retard Vir. Inside the capsules of Venlafaxina Retard Vir, there is a small tablet that contains the active ingredient venlafaxine. This tablet is released from the capsule in the gastrointestinal tract. Since it moves along the length of the gastrointestinal tract, venlafaxine is released slowly. The "shell" of the tablet remains undissolved and is eliminated in the stool. Therefore, although you may see a tablet in your stool, your dose of venlafaxine has been absorbed.

If you experience any of the following effects, do not take more Venlafaxina Retard Vir. Inform your doctor immediately, or go to the nearest hospital emergency room:
