Venlafaxina Kern Pharma 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 experience anxiety 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 Kern Pharma 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 improve or may worsen and become more difficult to treat.

Do not take Venlafaxina Kern Pharma

• If you are allergic to venlafaxine or any of the other ingredients of 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 other medications, including Venlafaxina Kern Pharma, may produce severe or potentially fatal side effects. Additionally, you must wait at least 7 days after stopping Venlafaxina Kern Pharma before taking any IMAO irreversible (see also the sections “Serotonin syndrome” and “Use of Venlafaxina Kern Pharma with other medications”).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Venlafaxina Kern Pharma.

• If you are taking other medications that are taken concomitantly with venlafaxine Kern Pharma, it may increase the risk of developing serotonin syndrome (see section “Use of Venlafaxina Kern Pharma with other medications”).
• If you have eye problems such as certain types of glaucoma (increased pressure in the eye).
• 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), or if you are using other medications that may increase the risk of bleeding, or if you are pregnant (see “Pregnancy”).
• If your cholesterol levels are high.
• If you have a history of mania or bipolar disorder (feeling overexcited or euphoric).
• If you have a history of aggressive behavior.

Venlafaxina Kern Pharma may cause a feeling of restlessness or an inability to sit or stand still. You should consult your doctor if this occurs.

Do not drink alcohol during treatment with Venlafaxina Kern Pharma, as it may cause extreme drowsiness 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 anxiety disorders, you may have thought about harming yourself or committing suicide. These thoughts may increase when you start taking antidepressants, as these medications take time to work, usually two weeks, but sometimes longer.

You may be more likely to have these thoughts:

• 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 conditions treated with antidepressants.

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

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. They may ask 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 good care of your oral hygiene.

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

Use in children and adolescents under 18 years of age

Venlafaxina Kern Pharma should not be used in children and adolescents under 18 years of age. Additionally, you should know that patients under 18 years of age have an increased risk of adverse effects such as suicidal behavior, suicidal thoughts, and there has been an increase in reports of hostility (predominantly aggression, oppositional behavior, and anger) when they take this group of medications. Despite this, the doctor who prescribes Venlafaxina Kern Pharma may prescribe it to patients under 18 years of age when they decide it is in the best interest of the patient. If your doctor has prescribed Venlafaxina Kern Pharma to a patient under 18 years of age and you want to discuss this decision, talk to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen in patients under 18 years of age who are taking Venlafaxina Kern Pharma. Additionally, the long-term safety effects of venlafaxine on growth, maturation, and development in this age group have not been demonstrated.
