6. Contents of the pack and other information

1. What Venlafaxine Tablets are and what they are used for

Venlafaxine Tablets contains Venlafaxine Hydrochloride as the active ingredient. Venlafaxine 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.

People who are depressed may have lower levels than usual of substances called "serotonin" and “noradrenaline" in their brain. While it is not fully understood how anti-depressants work, Venlafaxine may help by increasing the levels of these substances in your brain.

Venlafaxine is a treatment for adults with depression. Treating depression properly is important to help you get better. If it is not treated, your condition may not go away and may become more serious and more difficult to treat.

2. What you need to know before you take Venlafaxine Tablets Do not take Venlafaxine tablets if

•    you are allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6)

•    you are also taking, or have taken within the last 14 days, any medicines known as irreversible monoamine oxidase inhibitors (MAOIs), used to treat depression or Parkinson's disease. Taking an irreversible MAOI together with Venlafaxine can cause serious or even life- threatening side effects. Also you must wait at least one week after you stop taking Venlafaxine tablets before you can take an MAOI.

Warnings and precautions

Talk to your doctor or pharmacist before taking Venlafaxine if you:

•    use other medicines that taken together with Venlafaxine could increase the risk of developing serotonin syndrome (see the section "Other medicines and Venlafaxine tablets").

•    have eye problems, such as certain kinds of glaucoma (increased pressure in the eye).

•    have a history of high blood pressure.

•    have a history of heart problems.

•    have been told you have an abnormal heart rhythm.

•    have a history of fits (seizures).

•    have a history of low sodium levels in your blood (hyponatraemia).

•    have a tendency to develop bruises or a tendency to bleed easily (history of bleeding disorders), or if you are taking other medicines that may increase the risk of bleeding e.g. warfarin (used to prevent blood clots).

•    have a history of, or if someone in your family has had, mania or bipolar disorder (feeling over-excited or euphoric).

•    have a history of aggressive behaviour.

Venlafaxine may cause a sensation of restlessness or an inability to sit or stand still during the first few weeks of treatment. You should tell your doctor if this happens to you. Thoughts of suicide and worsening of your depression or anxiety disorder

If you are depressed and /or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.

You may be more likely to think like this:

•    If you have previously had thoughts about killing or harming yourself

•    If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in young adults (less than 25 years old) with psychiatric conditions who were treated with an antidepressant.

If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.

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 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 behaviour.

Dry mouth

Dry mouth is reported in 1 in 10 patients treated with Venlafaxine. This may increase the risk of tooth decay (dental caries). Therefore, you should take special care with your dental hygiene.

Diabetes

Your blood glucose levels may be altered due to Venlafaxine. Therefore, the dosage of your diabetes medicines may need to be adjusted.

Children and adolescents

Venlafaxine should normally not be used for children and adolescents under 18 years. Also, you should know that patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Despite this, your doctor may prescribe Venlafaxine for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed Venlafaxine for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking Venlafaxine. Also, the long-term safety concerning growth, maturation and cognitive and behavioural development of the brain in this age group have not yet been demonstrated.

Other medicines and Venlafaxine Tablets

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 medicines, including those bought without a prescription, natural and herbal remedies, before checking with your doctor or pharmacist.

•    Monoamine oxidase inhibitors which are used to treat depression or Parkinson's disease must not be taken with Venlafaxine. Tell your doctor if you have taken these medicines within the last 14 days. (MAOIs: see section 2).

   Serotonin syndrome:

A potentially life-threatening condition or Neuroleptic Malignant Syndrome (NMS)-like reactions (see the section "Possible Side Effects"), may occur with venlafaxine treatment, particularly when taken with other medicines.

Examples of these medicines include:

•    Medicines for migraine such as sumatriptan (triptans)

•    Medicines for depression such as fluoxetine (SSRI), duloxetine (SNRI), imipramine (tricyclics), or medicines containing lithium

•    Antibiotics, such as linezolid, used to treat infections

•    Medicines used to treat depression such as moclobemide (called reversible MAOIs)

•    Medicines to help with weight loss such as sibutramine

•    Medicines containing dextromethorphan (used to treat coughing)

•    Medicines containing methadone (used to treat opioid drug addiction or severe pain)

•    Medicines containing methylene blue (used to treat high levels of methaemoglobin in the blood)

•    Medicines containing tramadol, fentanyl, tapentadol, pethidine, or pentazocine (used to treat severe pain)

•    Products containing St. John's Wort (also called Hypericum perforatum, a natural or herbal remedy 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 sensing things which are not there, mistaken beliefs, unusual suspiciousness, unclear reasoning and becoming withdrawn)

Signs and symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, fast heart beat, increased body temperature, fast changes in blood pressure, overactive reflexes, diarrhoea, nausea, coma, vomiting.

In its most severe form, serotonin syndrome can resemble Neuroleptic Malignant Syndrome (NMS). Signs and symptoms of NMS may include a combination of fever, fast heart beat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).

Tell your doctor immediately, or go to the casualty department at your nearest hospital if you think serotonin syndrome is happening to you.

You must tell your doctor if you are taking medicines that can affect your heart rhythm. 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 allergy)

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:

•    Ketoconazole (to treat fungal infections)

•    Haloperidol or risperidone (to treat psychiatric conditions)

•    Metoprolol (a beta blocker to treat high blood pressure and heart problems) Venlafaxine Tablets with food, drink and alcohol

•    Venlafaxine should be taken with food (see section 3)

•    You should avoid alcohol while you are taking Venlafaxine Tablets.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, 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 use Venlafaxine only after discussing the potential benefits and the potential risks to your unborn child with your doctor.

If you are taking this medicine and you find out that you are pregnant, make sure your midwife and/or doctor know you are on Venlafaxine Tablets. When taken during pregnancy, similar drugs (SSRIs) may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the new born (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.

If you are taking this medicine during pregnancy, other symptoms your baby might have when it is born is not feeding properly, in addition to having trouble breathing. If your

baby has these symptoms when it is born and you are concerned, contact your doctor and/or midwife who will be able to advise you.

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