Content of the prospect:

Venlafaxina Retard Qualigen contains the active ingredient venlafaxine.

Venlafaxina Retard Qualigen is an antidepressant that belongs to a group of medicines called serotonin and norepinephrine reuptake inhibitors (SNRIs). This group of medicines is used to treat depression and other conditions such as anxiety disorders. The exact way in which antidepressants work is not fully understood, but they may help increase the levels of serotonin and norepinephrine in the brain.

Venlafaxina Retard Qualigen is a treatment for adults with depression. It is also a treatment for adults with the following anxiety disorders: social anxiety disorder (fear or avoidance of social situations), generalized anxiety disorder, and panic disorder. 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 Venlafaxina Retard Qualigen

• If you are allergic to venlafaxine or any of the other components of Venlafaxina Retard Qualigen.

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 Venlafaxina Retard Qualigen may produce severe or potentially fatal adverse effects. Additionally, you must wait at least 7 days once you stop taking Venlafaxina Retard Qualigen before taking any IMAO irreversible (see also the section “Taking Venlafaxina Retard Qualigen with other medications” and the information in that section on “Serotonin syndrome”).

Warnings and precautions

Consult your doctor or pharmacistbeforestarting to take Venlafaxina Retard Qualigen:

• If you are using other medications that taken with Venlafaxina Retard Qualigen may increase the risk of developing serotonin syndrome (see the section “Other medications and Venlafaxina Retard Qualigen”).
• 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 cardenalias or a tendency to bleed easily (history of hemorrhagic disorders), 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 “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.

Venlafaxina Retard Qualigen may cause a feeling of restlessness or difficulty sitting or being still during the first weeks of treatment. You should consult your doctor if this occurs.

Do not drink alcohol while you are being treated with Venlafaxina Retard Qualigen, as it may cause extreme fatigue and unconsciousness. The concomitant use with alcohol and/or certain medications may worsen your symptoms of depression and other conditions, such as anxiety disorders..

Thoughts of suicide and worsening of your 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, as all these medications take time to become effective, usually two weeks but sometimes longer.These thoughts may also occur when your dose is reduced or during the interruption of treatment with venlafaxine.

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

Diabetes

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

Sexual problems

Additionally, you should know that in patients under 18 years oldthere is agreater risk of adverse effects such as attempts at suicide,suicidal thoughtsand hostility (predominantly aggression, confrontational behavior and irritability) when they ingest this type of medication. However, the doctor who prescribes it to you may prescribe this medication to patients under 18 years old when they decide what is best for the patient. Ifyour doctorhas prescribed this medication to a patient under 18 years old and wants to discuss this decision,please go backto your doctor.
