Content of the prospect

This medication contains the active ingredient venlafaxine.

Venlafaxine 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 norepinephrine in the brain. The exact mechanism of how antidepressants work is not fully understood, but they may help increase the levels of serotonin and norepinephrine in the brain.

Venlafaxina Retard Davurgama is a treatment for adults with depression. It is also a treatment for adults with the following anxiety disorders: generalized anxiety disorder, social anxiety disorder (fear or avoidance of social situations), panic disorder (panic attacks). 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 more difficult to treat.

Do not take Venlafaxina Retard Davurgama

• If you are allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
• If you are also taking or have taken in the last 14 days, any medicine known as an irreversible monoamine oxidase inhibitor (IMAO), used to treat depression or Parkinson's disease. Taking an IMAO irreversible with venlafaxine may cause severe or potentially fatal side effects. Also, you should wait at least 7 days after stopping venlafaxine before taking any IMAO irreversible (see also the section “Other medicines and Venlafaxina Retard Davurgama” and the information in that section on “Serotonin syndrome”).

Warnings and precautions

Consult your doctor before starting to take Venlafaxina Retard Davurgama:

• If you are taking other medicines that taken with venlafaxine may increase the risk of developing serotonin syndrome (see section “Other medicines and Venlafaxina Retard Davurgama”)
• 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 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 tendency to develop cardenals or a tendency to bleed easily (history of bleeding disorders), if you are taking other medicines that may increase the risk of bleeding, e.g., warfarin (used to prevent blood clots), or if you are pregnant.
• 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.

This medicine may cause a feeling of restlessness or difficulty sitting or staying still during the first weeks of treatment. You should consult your doctor if this happens.

Do not drink alcohol during treatment with venlafaxine, as it may cause extreme fatigue and unconsciousness. Taking it with certain medicines 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 thoughts may increase when you start taking antidepressants, because all these medicines take time to work, usually two weeks but sometimes longer. These thoughts may also occur when your dose is reduced or during the interruption of treatment with venlafaxina.

It is more likely to happen:

• If you have had thoughts of suicide or self-harm before.
• 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 illnesses treated with antidepressants.

Immediately contact your doctor or go to the nearest hospital 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. Therefore, you should take good care of your dental hygiene.

Diabetes

Your blood glucose levels may be affected by venlafaxine. Therefore, your doses of diabetes medicines may need to be adjusted.

Sexual problems

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

Beads in chains

Do not worry if you see small white grains or beads in your stools after taking this medicine. Inside the capsules of Venlafaxina Retard Davurgama there are beads (small white beads) that contain the active ingredient (venlafaxine). These beads are released from the capsule in the stomach. As they travel through the stomach and intestines, venlafaxine is released slowly. The “shell” of the bead remains undissolved and is eliminated in the stools. Therefore, although you may see beads in your stools, your dose of medicine has been absorbed.

Children and adolescents

This medicine should not be used normally in the treatment of children and adolescents under 18 years old. Also, you should know that in patients under 18 years old there is a higher risk of side effects such as suicidal thoughts, suicidal behavior, and hostility (mainly aggression, confrontational behavior, and irritability) when taking this type of medicine. 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 go back 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. Also, the long-term effects on safety, growth, maturity, and cognitive and behavioral development of this medicine in this age group have not yet been demonstrated.

Other medicines and Venlafaxina Retard Davurgama

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

Your doctor must decide if you can take venlafaxine with other medicines.

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

• Irreversible monoamine oxidase inhibitors used to treat depression or Parkinson's disease should not be taken with this medicine. Tell your doctor if you have taken any of these medicines in the last 14 days. (IMAO: see section “Do not take Venlafaxina Retard Davurgama”)
• Serotonin syndrome:

A potentially fatal or reactions similar to Malignant Neuroleptic Syndrome (MNS) (see section “Possible side effects”), may occur with treatment with venlafaxine, particularly when taken with other medicines.

Examples of these medicines include:

• Triptans (used for migraines)
• Other medicines to treat depression, for example, IRSNs, ISRSs, tricyclic antidepressants, or medicines containing lithium
• Medicines containing amphetamines (used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity)
• Medicines containing the antibiotic linezolid (used to treat infections)
• Medicines containing moclobemida, an IMAO (used to treat depression)
• Medicines containing sibutramine (used for weight loss)
• Medicines containing tramadol, fentanil, tapentadol, pethidine, or pentazocine (used to treat severe pain)
• Medicines containing dextromethorphan (used to treat cough)
• Medicines containing methadone (used to treat opioid addiction or to treat severe pain) and buprenorphine
• Medicines containing methylene blue (used to treat high levels of methemoglobin in the blood)
• Medicines containing St. John's Wort (also known as Hypericum perforatum, a natural remedy or herbal remedy used to treat mild depression)
• Medicines containing tryptophan (used for problems such as sleep and depression).
• Antipsychotics (used to treat illnesses with symptoms such as hearing, seeing, or feeling things that are not there, false beliefs, unusual suspicion, unclear thinking, and becoming withdrawn)

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.

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

Inform your doctor immediately or go to the nearest hospital if you think you are experiencing serotonin syndrome.

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

Some examples of these medicines 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 medicines may also interact with venlafaxine and should be used with caution. It is especially important to mention to your doctor or pharmacist if you are taking medicines that contain:

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

Taking Venlafaxina Retard Davurgama with alcohol

Do not drink alcohol during treatment with venlafaxine. 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 think you may be pregnant, consult your doctor or pharmacist before using this medicine. You should only take venlafaxine after discussing the possible benefits and risks for the unborn baby with your doctor.

Make sure your midwife and/or doctor knows that you are taking venlafaxine. When taken during pregnancy, similar medicines (ISRs) may increase the risk of a serious illness in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear blue. These symptoms usually start within the first 24 hours after the baby's birth. If this happens to your baby, contact your midwife and/or doctor immediately.

If you take this medicine in the final stages of pregnancy, there may be a higher 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 venlafaxina to be able to advise you.

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

Venlafaxine 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 to stop breastfeeding or stop taking this medicine.
