Venlafaxine Retard Stadagen 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. It is not fully understood how antidepressants work, but they may help to increase the levels of serotonin and norepinephrine in the brain.
Venlafaxine Retard Stadagen 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) and panic disorder (panic attacks). Treating depressive and anxiety disorders adequately is important to help you feel better. If left untreated, your condition may not improve or may worsen and become more difficult to treat.
Consult your doctor or pharmacist before taking venlafaxine if you:
Venlafaxine Retard Stadagen may cause a feeling of restlessness or difficulty sitting or standing still during the first few weeks of treatment. You should consult your doctor if this happens to you.
Do not drink alcohol during treatment with venlafaxine, as it may cause extreme fatigue and unconsciousness. Taking it with certain medicines and/or with alcohol may worsen symptoms of depression and other conditions, such as anxiety disorders.
If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or suicide. These thoughts may increase when you first start taking antidepressants, as these medicines take time to work, usually around 2 weeks, but sometimes longer. These thoughts can also occur when your dose is reduced or during treatment interruption with venlafaxine.
This is more likely to happen:
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 relative or close 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 worried about changes in your behavior.
Dry mouth
Dry mouth has been reported in 10% of patients treated with venlafaxine. This can increase the risk of tooth decay (caries). Therefore, you should be careful with your dental hygiene.
Diabetes
Your blood glucose levels may be altered by venlafaxine. Therefore, the doses of your diabetes medicines may need to be adjusted.
Sexual problems
Some medicines in the same group as venlafaxine (called SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.
Venlafaxine should not normally be used in the treatment of children and adolescents under 18 years of age. Also, you should know that in patients under 18 years of age, there is a greater risk of adverse effects such as suicidal attempts, suicidal thoughts, and hostility (mainly aggression, confrontational behavior, and irritation) when taking this class of medicines. Despite this, your doctor may prescribe this medicine to patients under 18 years of age when they decide it is the most convenient for the patient. If your doctor has prescribed this medicine to a patient under 18 years of age and you want to discuss this decision, please go back to your doctor. You should inform your doctor if any of the above symptoms develop or worsen when these patients under 18 years of age are taking venlafaxine.
Additionally, long-term safety in relation to growth, maturity, and cognitive and behavioral development has not been demonstrated.
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
Your doctor must decide if you can take venlafaxine with other medicines.
Do not start or stop taking any medicines, including those that can be bought without a prescription, herbal remedies, and complementary medicines, before checking with your doctor or pharmacist.
A potentially life-threatening condition, or reactions similar to Neuroleptic Malignant Syndrome (NMS) (see section “Possible side effects”) may occur with venlafaxine treatment, particularly when taken with other medicines.
Examples of these medicines include:
The signs and symptoms of serotonin syndrome can include a combination of the following: restlessness, hallucinations, loss of coordination, rapid heartbeat, increased body temperature, rapid changes in blood pressure, overactive reflexes, diarrhea, coma, nausea, vomiting.
In its most severe form, serotonin syndrome can resemble Neuroleptic Malignant Syndrome (NMS). The signs and symptoms of NMS can include a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
Tell your doctor immediately or go to the emergency department of the nearest hospital if you think you are experiencing serotonin syndrome.
Tell your doctor if you are taking medicines that may affect your heart rhythm.
Some examples of these medicines include:
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 containing:
Venlafaxine should be taken with food (see section 3 “How to take Venlafaxine Retard Stadagen”).
Do not drink alcohol during treatment with venlafaxine. Taking it with alcohol may cause extreme fatigue and unconsciousness, and worsen symptoms of depression and other conditions, such as anxiety disorders.
Pregnancy
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should only take venlafaxine after discussing with your doctor the possible benefits and risks to the unborn child.
Make sure your midwife and/or doctor knows you are taking venlafaxine. When taken during pregnancy, similar drugs (SSRIs) may increase the risk of a serious condition in babies called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and turn blue. These symptoms usually start during the first 24 hours after the baby is born. If this happens to your baby, you must contact your midwife and/or doctor immediately.
If you take venlafaxine in the final stages of pregnancy, there may be an increased 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 venlafaxine so they can advise you.
If you are taking this medicine during pregnancy, other symptoms your baby may have when born are problems with feeding and problems with breathing. If your baby has these symptoms when born and you are worried, contact your doctor and/or midwife who can advise you.
Breastfeeding
Venlafaxine passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss this with your doctor and they will decide whether you should stop breastfeeding or stop taking this medicine.

Do not stop taking your treatment or reduce the dose without your doctor's advice, even if you feel better. If your doctor thinks you no longer need venlafaxine, they may ask you to reduce the dose gradually before stopping treatment completely.
It is known that side effects occur when people stop using this medicine, especially when it is stopped suddenly or if the dose is reduced too quickly.

Blood Tests
Venlafaxine sometimes produces unwanted effects that you may not be aware of, such as increased blood pressure or abnormal heartbeat; mild changes in blood levels of liver enzymes, sodium, or cholesterol.

Therefore, your doctor may want to perform occasional blood tests, especially if you have been taking venlafaxine for a long time.
