Venlafaxine NORMON 50 mg Film-Coated Tablets
Contents of the pack
Venlafaxine NORMON 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 thought that people who are depressed and/or have anxiety have lower levels of serotonin and noradrenaline in the brain. The way that antidepressants work is not fully understood but they may help to increase the levels of serotonin and noradrenaline in the brain.
Venlafaxine NORMON is used to treat adults with depression. Treating depression properly is important to help you feel better. If it is not treated, your condition may not improve or may get worse and become more difficult to treat.
Do not take Venlafaxine NORMON
Warnings and precautions
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Venlafaxine NORMON may cause a feeling of restlessness or an inability to sit or stand still. You should see your doctor if this happens.
Some medicines of the same group as Venlafaxine NORMON (called SSRIs/ SNRIs) may cause sexual dysfunction (see section 4). In some cases, these symptoms have persisted after stopping treatment.
If any of these apply to you, consult your doctor before taking Venlafaxine NORMON.
Do not drink alcohol while you are taking Venlafaxine NORMON, as it may increase the risk of side effects such as drowsiness. Taking it with certain medicines or alcohol may worsen your depression or 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 or killing yourself. These thoughts may be more frequent when you first start taking antidepressants, since these medicines all take time to work, usually about 2 weeks, but sometimes longer.
You may be more likely to think this way if:
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 has been reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay. Therefore, you should be careful with your dental hygiene.
Use in children and adolescents under 18 years of age
Venlafaxine NORMON should not be used for children and adolescents under 18 years of age. In addition, you should know that patients under 18 have an increased risk of side effects such as suicide attempt, suicidal thoughts, and there was an increase in reports of hostility (predominantly aggression, oppositional behaviour, and anger) when they took this group of medicines. Despite this, the doctor who prescribes you Venlafaxine NORMON may prescribe it to patients under 18 when they decide that it is the best for the patient. If your doctor has prescribed Venlafaxine NORMON to a patient under 18 and you wish to discuss this decision, talk to your doctor. You should inform your doctor if any of the above symptoms develop or worsen when these patients under 18 are taking Venlafaxine NORMON. Also, the long-term safety of venlafaxine regarding growth, maturation, and development in this age group has not been demonstrated.
Taking Venlafaxine NORMON with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor will decide whether you can take Venlafaxine NORMON with other medicines.
Do not start or stop taking any medicines, including those that can be bought without a prescription, herbal or natural remedies, before checking with your doctor or pharmacist.

Get medical help immediately if you think you are experiencing serotonin syndrome.

If you are taking Venlafaxine NORMON during pregnancy, tell your midwife or doctor, as your baby may have some symptoms when it is born.

If your baby has these symptoms when it is born and you are concerned, contact your doctor or midwife who will be able to advise you.
If you are taking Venlafaxine NORMON during pregnancy, tell your midwife or doctor. When similar medicines (called selective serotonin reuptake inhibitors, SSRIs) are taken during pregnancy, there is a potential increased risk that the baby will develop a serious condition called persistent pulmonary hypertension of the newborn (PPHN), which makes the baby breathe faster and appear bluish. These symptoms usually start during the first 24 hours after birth. If this happens to your baby, you should contact a doctor or midwife immediately.
If you take Venlafaxine NORMON in the last few months of your pregnancy, you may experience an increased risk of heavy bleeding after giving birth, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Venlafaxine NORMON so that they can advise you.
Venlafaxine NORMON 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 Venlafaxine NORMON.
