Contents of the pack and other information
Venlafaxine Retard Viatris contains the active substance venlafaxine and is an antidepressant that belongs to a group of medicines called serotonin and noradrenaline reuptake inhibitors (SNRIs). This group of medicines is used to treat depression and other conditions such as anxiety disorders.
Venlafaxine is a treatment for adults with depression or to prevent the recurrence of depressive episodes. Venlafaxine 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). Properly treating depression and anxiety 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 Venlafaxine Retard Viatris:
Warnings and precautions
Consult your doctor or pharmacist before starting treatment with Venlafaxine Retard Viatris:
During treatment
Do not drink alcohol during treatment with Venlafaxine Retard Viatris, as it may cause extreme fatigue and unconsciousness. Taking it with certain medicines and/or alcohol may worsen symptoms of depression and other conditions, such as anxiety disorders.
Suicidal thoughts 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 suicide. These thoughts may increase when you first start taking antidepressants, as these medicines take time to work, usually around two weeks, but sometimes longer. These thoughts may also occur when you reduce the dose or during the discontinuation of treatment with venlafaxine.
This is more likely to happen:
If you have thoughts of suicide or self-harm at any time, contact your doctor or go to the hospital immediately.
It may be helpful to tell a relative or close friendthat you are depressed or have an anxiety disorder and ask them to read this leaflet. You can 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
10% of patients treated with venlafaxine report dry mouth. This may increase the risk of dental caries. Therefore, you should be careful with your dental hygiene.
Diabetes
Your blood glucose levels may be altered due to venlafaxine, so it may be necessary to adjust the dose of your diabetes medicines.
Sexual dysfunction
Some medicines in the same group as Venlafaxine Retard Viatris (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.
Children and adolescents
Venlafaxine should not normally be used for the treatment of children and adolescents under 18 years of age. Additionally, you should know that in patients under 18 years of age, there is an increased risk of side effects such as suicidal attempts, suicidal thoughts, and hostility (mainly aggression, confrontational behavior, and irritability) when taking this class of medicines. Nevertheless, your doctor may prescribe this medicine to patients under 18 years of age when he/she decides that it is the best option for the patient. If your doctor has prescribed this medicine to a patient under 18 years of age and you wish to discuss this decision, please consult your doctor again. You should inform your doctor if any of the above symptoms worsen or if you experience complications when patients under 18 years of age are taking venlafaxine. Studies in this age group with this medicine have not shown conclusively whether this medicine affects growth, maturity, and cognitive and behavioral development.
Other medicines and Venlafaxine Retard Viatris
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription or herbal remedies.
Your doctor must decide whether you can take venlafaxine with other medicines.
Serotonin syndrome: a potentially life-threatening or fatal disease, or reactions similar to neuroleptic malignant syndrome (NMS) (see section “Possible side effects”), may occur with treatment with venlafaxine, particularly when taken with other medicines.
Examples of these medicines include:
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, 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 may include a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, mood changes, 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 suffering from serotonin syndrome or NMS.
You must tell your doctor if you are taking medicines that may affect the heart rhythm.
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:
Taking Venlafaxine Retard Viatris with food, drinks, and alcohol
Venlafaxine Retard Viatris should be taken with food (see section 3 "How to take Venlafaxine Retard Viatris").
Do not drink alcohol during treatment with Venlafaxine Retard Viatris. Taking it with alcohol may cause extreme fatigue and unconsciousness, and worsen symptoms of depression and other conditions, such as anxiety disorders.
Pregnancy and breastfeeding
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 the potential benefits and risks to the fetus with your doctor.
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 immediately contact your midwife and/or doctor.
If you are taking this medicine during pregnancy, in addition to breathing difficulties, another symptom your baby may have when born is problems with breastfeeding. If you notice your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife, who can advise you.
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 breastfeeding, ask your doctor for advice. Venlafaxine passes into breast milk. There is a risk of affecting the baby. Therefore, you should discuss this with your doctor, and he will decide whether you should stop breastfeeding or stop the treatment with venlafaxine.
Driving and using machines
Do not drive or operate tools or machines until you know how the treatment with venlafaxine affects you, as this medicine may affect your judgment, reasoning, or ability to drive or operate machines.
This medicine contains less than 1 mmol sodium (23 mg) per capsule;that is, it is essentially “sodium-free”.
Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
The recommended initial dose for the treatment of depression, generalized anxiety disorder, and social anxiety disorder is usually 75 mg per day. Your doctor may gradually increase the dose and, if necessary, even more, up to a maximum of 375 mg per day for depression. If you are being treated for panic disorder, your doctor will start with a lower dose (37.5 mg) and then gradually increase the dose. The maximum dose for generalized anxiety disorder, social anxiety disorder, and panic disorder is 225 mg/day. You may be advised to take this medication for several months depending on your condition; likewise, you will likely have regular check-ups during treatment.
Take venlafaxine approximately at the same time every day, either in the morning or at night. The capsules should be swallowed whole with liquids and should not be opened, crushed, chewed, or dissolved.
This medication should be taken with food.

If you forget to take Venlafaxine Retard Viatris
If you have not taken a dose, take it as soon as you remember. However, if it is already time for your next dose, skip the missed dose and take only one dose as usual. Do not take a double dose to make up for missed doses. Do not take more than the daily amount of the slow-release venlafaxine medication that has been prescribed for you.
If you stop treatment with Venlafaxine Retard Viatris
Do not stop taking your treatment or reduce the dose without your doctor's advice, even if you feel better. If your doctor believes you no longer need venlafaxine, they may ask you to gradually reduce the dose before stopping treatment altogether. It is known that adverse effects occur when people stop using this medication, especially when stopped suddenly or if the dose is reduced too quickly. Some patients may experience symptoms such as suicidal thoughts, aggression, fatigue, dizziness, drowsiness, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, feeling of anxiety, nervousness, agitation, confusion, ringing in the ears, tingling, or, in rare cases, a sensation of electric discharge, weakness, sweating, convulsions, tremors, flu-like symptoms, and vision problems and increased blood pressure (which can cause headache, dizziness, ringing in the ears, sweating, etc.).
Your doctor will advise you on how to gradually stop treatment with venlafaxine. This process can take several weeks or months. For some patients, treatment may be stopped gradually over several months or more. If you experience any of these or other symptoms that bother you, consult your doctor for further advice.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
Like all medications, this medication can cause side effects, although not everyone will experience them.
If you experience any of the following effects, do not take more venlafaxine. Inform your doctor immediately or go to the emergency department of the nearest hospital:
Uncommon (may affect up to 1 in 100 people):
Rare (may affect up to 1 in 1,000 people)
In its most severe form, serotonin syndrome can resemble neuroleptic malignant syndrome (NMS). Among the signs and symptoms of NMS are a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
Frequency not known (cannot be estimated from available data)
Other adverse effects that you should report to your doctor include (the frequency of these adverse effects is included in the list "Other adverse effects that may occur" below):
Do not worry if you notice small white balls or granules in your stool after taking this medication. Inside the venlafaxine capsules are spheroids (small white balls) that contain the active ingredient (venlafaxine). The spheroids come out of the capsules in the stomach, and venlafaxine is slowly released as the spheroids move through the stomach into the intestine. The "shell" of the spheroids does not dissolve and is deposited in the stool. This means that, despite seeing the spheroids in your stool, the dose of the medication will have been absorbed.
Other possible side effects:
Common (may affect up to 1 in 10 people)
Uncommon (may affect up to 1 in 100 people)
Rare (may affect up to 1 in 1,000 people)
Very rare (may affect up to 1 in 10,000 people)
Frequency not known (cannot be estimated from available data)
Sometimes, venlafaxine causes unwanted effects that you may not be aware of, such as high blood pressure or abnormal heartbeats, or mild changes in blood levels of liver enzymes, sodium, and cholesterol. Venlafaxine rarely reduces the function of platelets in the blood, leading to an increased risk of bruising or bleeding. Therefore, your doctor may want to perform blood tests occasionally, especially if you have been taking venlafaxine for a long time.
Other side effects in children and adolescents
Although this medication is not usually recommended for children and adolescents, cases of hostility, self-harm, stomach pain, indigestion, heartburn, and muscle pain have also been reported.
