1. What is Venlafaxine Sandoz and what is it used for

Venlafaxine Sandoz contains the active substance venlafaxine.

Venlafaxine 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. It is thought that people who are depressed and/or anxious have lower levels of serotonin and noradrenaline in the brain.

Venlafaxine is a treatment for adults with depression. Treating depression adequately is important to help you feel better. If it is not treated, your depressive state may not disappear or may become worse and more difficult to treat.

2. What you need to know before you take Venlafaxine Sandoz

Do not take Venlafaxine Sandoz

• if you are allergic to venlafaxineor any of the other ingredients of this medicine (listed in section 6),
• if you are taking or have taken in the last 14 days irreversible monoamine oxidase inhibitors(MAOIs), used to treat depression or Parkinson's disease. Taking MAOIs with venlafaxine can cause serious side effects, even fatal ones. Also, you should wait at least 7 days after stopping venlafaxine before taking any MAOI (see also section “Other medicines and Venlafaxine Sandoz” and the information in this section on “Serotonin syndrome”).

Warnings and precautions

Consult your doctor or pharmacist before starting to take venlafaxine.

• if you are using other medicines taken together with venlafaxine, it could increase the risk of developing serotonin syndrome (see section “Other medicines and Venlafaxine Sandoz”),
• 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 you have abnormal heart rhythms,
• 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 bruises or tend to bleed easily (history of bleeding disorders), or if you are using other medicines 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.

Venlafaxine may cause a feeling of restlessness or an inability to sit or stand still during the first few weeks of treatment. You should consult your doctor if this happens to you.

Some medicines in the group that Venlafaxine Sandoz belongs to (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.

Do not drink alcohol during treatment with Venlafaxine Sandoz, as it may cause extreme fatigue and unconsciousness. Taking it together 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 anxiety disorders, you may sometimes have thoughts of harming yourself or suicide. These thoughts may increase when you start taking antidepressants, as these medicines take time to work, usually about two weeks, but sometimes longer. These thoughts may also occur when your dose is reduced or during discontinuation of treatment with venlafaxine.

You maybe more likely to think this way:

• if you have previously had thoughts of suicide or self-harm,
• if you are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior in young adults (less than 25 years of age) with psychiatric conditions who were 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 relative or close friendthat you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might 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 may increase the risk of tooth decay (caries). Therefore, you should be careful with your oral hygiene.

Diabetes

Your blood sugar levels may be altered by venlafaxine. Therefore, you may need to adjust the dose of your diabetes medicines.

Children and adolescents

Venlafaxine should not be used for children and adolescents under 18 years of age. Also, you should know that patients under 18 years of age have an increased risk of side effects such as suicide attempts and suicidal thoughts, and there was an increase in reports of hostility (mainly aggression, oppositional behavior, and anger) when taking this group of medicines.

Despite this, the doctor who treats you may prescribe this medicine to patients under 18 years of age when he decides what is best 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, tell your doctor. You should inform your doctor if any of the above symptoms appear or worsen when these patients under 18 years of age are taking this medicine.

Additionally, the long-term safety effects of this medicine on growth, maturation, and development in this age group have not been established.

Other medicines and Venlafaxine Sandoz

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Your doctor should decide whether you can take venlafaxine with other medicines.

Do not start or stop taking any other medicines, including those that can be bought without a prescription, natural remedies, and herbal products, before consulting your doctor or pharmacist.

• Monoamine oxidase inhibitors used to treat depression or Parkinson's disease should not be taken with venlafaxine.Tell your doctor if you have taken these medicines in the last 14 days (MAOIs: see the section “What you need to know before you take Venlafaxine Sandoz”)
• Serotonin syndrome:

A potentially life-threatening condition, 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:

• triptans (used for migraine),
• other medicines for treating depression, for example, SSRIs, SNRIs, tricyclic antidepressants, or medicines containing lithium,
• medicines containing amphetamines (used for treating attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity),
• medicines containing the antibiotic linezolid (used to treat infections),
• medicines containing moclobemide, an MAOI (used to treat depression),
• medicines containing sibutramine (used for weight loss),
• medicines containing opioids (e.g., buprenorphine, tramadol, fentanyl, tapentadol, pethidine, or pentazocine) used to treat severe pain,
• medicines containing dextromethorphan (used to treat cough),
• medicines containing methadone (used to treat addiction to opioid drugs or severe pain),
• medicines containing methylene blue (used to treat high levels of methemoglobin in the blood),
• products containing St. John's Wort (also known as “Hypericum perforatum”, a natural remedy or herbal product used to treat mild depression),
• products containing tryptophan (used for problems such as sleep and depression),
• antipsychotics (used to treat a disease with symptoms such as hearing, seeing, or feeling things that do not exist, mistaken beliefs, unusual suspicion, unclear reasoning, and tendency to withdraw).

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, 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.

You should tell your doctor if you are taking medicines that may affect your heart rhythm.

Examples of these medicines include:

• antiarrhythmics such as quinidine, amiodarone, sotalol, or dofetilide (used to treat abnormal heart rhythms),
• antipsychotics such as thioridazine (see also “Serotonin syndrome” above),
• antibiotics such as erythromycin or moxifloxacino (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 tell your doctor or pharmacist if you are taking medicines containing:

• ketoconazole (an antifungal medicine),
• haloperidol or risperidone (for treating psychiatric conditions),
• metoprolol (a beta-blocker for treating high blood pressure and heart problems).

Taking Venlafaxine Sandoz with food, drinks, and alcohol

Venlafaxine should be taken with food (see section 3 “How to take Venlafaxine Sandoz”).

Do not drink alcohol during treatment with Venlafaxine Sandoz. Taking it together 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 possible benefits and risks to the unborn child with your doctor.

Make sure your midwife and/or doctor knows you are taking venlafaxine. When taking similar medicines (SSRIs) during pregnancy, it may increase the risk of a serious condition in babies called persistent pulmonary hypertension of the newborn (PPHN), which makes the baby breathe faster and appear blue. These symptoms usually start during the first 24 hours after the baby is born. If this happens to your baby, you should contact your doctor and/or midwife immediately.

If you take this medicine during pregnancy, in addition to breathing problems, other symptoms your baby may have at birth may include inadequate feeding. If 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, it may cause 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.

Venlafaxine passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss this with your doctor, and he will decide whether you should stop breastfeeding or stop treatment with this medicine.

If you stop taking Venlafaxine Sandoz

Do not stop taking your treatment or reduce the dose without consulting your doctor, even if you feel better. If your doctor thinks you no longer need venlafaxine, he/she 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. Some patients may experience symptoms such as suicidal thoughts, aggression, fatigue, dizziness, instability, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, confusion, ringing in the ears, tingling or sensations of electric shock, weakness, sweating, seizures, or flu-like symptoms, vision problems, increased blood pressure (which can cause headache, fatigue, ringing in the ears, sweating, etc.).

Your doctor will advise you on how to gradually stop treatment with venlafaxine. This may take a few weeks or months. In some patients, it may be necessary for the discontinuation of treatment to take place very gradually over a period of months or even longer. If you experience any of these or other symptoms that bother you, consult your doctor for further advice.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
