Venlafaxina NORMON 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 NORMON is a treatment for adults with depression. Treating depressive disorders properly is important to help you feel better. If not treated, your condition may not go away or may worsen and become more difficult to treat.

Do not take Venlafaxina NORMON

• If you are allergic to the active ingredient or any of the other components 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 NORMON, may produce severe or potentially fatal side effects. You must also wait at least 7 days after stopping Venlafaxina NORMON before taking any IMAO irreversible (see also the sections “Serotonin syndrome” and “Use of other medications”).

Warnings and precautions

Consult your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

• If you use other medications that are taken concomitantly with Venlafaxina NORMON may increase the risk of developing serotonin syndrome (see section “Use of 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 cardenals or easily bleed (history of hemorrhagic disorders), or if you are using other medications that may increase the risk of bleeding, or if you are pregnant (see “Pregnancy and breastfeeding”).
• 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 NORMON may cause a feeling of restlessness or an inability to sit or stand still. You should consult your doctor if this occurs.

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

If you are applicable to any of these states, consult your doctor before taking Venlafaxina NORMON.

Do not drink alcohol during treatment with Venlafaxina NORMON, 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 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 directly.

You may find it helpful to tell a close friend or family member 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 be careful about your oral hygiene.

Use in children and adolescents under 18 years of age

Venlafaxina NORMON should not be used for children and adolescents under 18 years of age. You should also 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 NORMON may prescribe it to patients under 18 years of age when they decide it is best for the patient. If your doctor has prescribed Venlafaxina NORMON 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 when these patients under 18 years of age are taking Venlafaxina NORMON. Additionally, the long-term safety effects of venlafaxine on growth, maturation, and development in this age group have not been demonstrated.

Taking Venlafaxina NORMON with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. Your doctor must decide if you can take Venlafaxina NORMON with other medications.

Do not start or stop taking any medication, including those sold over the counter, natural remedies, and herbal supplements, without checking with your doctor or pharmacist.

• Irreversible monoamine oxidase inhibitors (IMAO: See section “Before taking Venlafaxina NORMON”)
• Serotonin syndrome: Serotonin syndrome, a potentially fatal condition, (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)
• Medications to treat depression, such as ISRN, ISRS, tricyclic antidepressants, or medications containing lithium
• Medications containing the antibiotic linezolid (used to treat infections)
• Medications containing moclobemida, a reversible IMAO (used to treat depression)

• Medications containing tramadol (a pain reliever)
• Products containing St. John's Wort (also known as “Hypericum perforatum”, a natural remedy or herbal supplement used to treat mild depression)
• Products containing tryptophan (used for problems such as sleep and depression)

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, nausea, vomiting, and coma. Seek medical attention immediately if you think you are experiencing serotonin syndrome.

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

Pregnancy and breastfeeding

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

If you are taking Venlafaxina NORMON during pregnancy, tell your midwife and/or doctor as your baby may have some symptoms when born. These symptoms usually start within the first 24 hours after birth. These include feeding problems and breathing problems. If your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife who can advise you.

If you are taking Venlafaxina NORMON during pregnancy, tell your midwife and/or doctor. When taken during pregnancy, similar medications (called serotonin reuptake inhibitors: ISRS) may increase the 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 occurs in your case, you should contact a doctor and/or midwife immediately.

If you take Venlafaxina NORMON 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 hemorrhagic disorders. Your doctor or midwife should know that you are taking Venlafaxina NORMON to be able to advise you.

Venlafaxina NORMON 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 NORMON.
