Venlafaxine NORMON 37.5 mg Effervescent 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 anxious have lower levels of serotonin and noradrenaline in the brain. Antidepressants are not fully understood, but they may help to increase the levels of serotonin and noradrenaline in the brain.
Venlafaxine NORMON is a treatment for adults with depression. Treating depressive disorders adequately is important to help you feel better. If left untreated, your condition may not disappear or may worsen 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 consult your doctor if this happens to you.
Some medicines in the group to which Venlafaxine NORMON belongs (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.
If any of these conditions apply to you, consult your doctor before taking Venlafaxine NORMON.
Do not drink alcohol during treatment with Venlafaxine NORMON, 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 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 around two weeks, but sometimes longer.
You may be more likely to think this way:
If you have thoughts of self-harm or suicide at any time, contact your doctor or go to a 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 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. Therefore, you should be careful with your oral 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. Also, you should know that patients under 18 years of age have an increased risk of side effects such as attempted suicide, 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 may prescribe Venlafaxine NORMON to patients under 18 years of age when they decide it is most convenient for the patient. If your doctor has prescribed Venlafaxine NORMON 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 develop or worsen when these patients under 18 years of age are taking Venlafaxine NORMON. Also, the long-term safety effects of venlafaxine on growth, maturation, and development in this age group have not been established.
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 sold without a prescription, natural remedies, and herbal products, before checking with your doctor or pharmacist.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. You should only use Venlafaxine NORMON after discussing the possible benefits and risks to the unborn child with your doctor.
If you are taking Venlafaxine NORMON during pregnancy, tell your midwife and/or doctor, as your baby may have some symptoms when born.

If your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife, who can advise you.
If you are taking Venlafaxine NORMON during pregnancy, tell your midwife and/or doctor. When similar medicines (called selective serotonin reuptake inhibitors: SSRIs) are taken during pregnancy, there may be an increased risk that the baby will suffer from a serious condition called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe more rapidly and appear blue. These symptoms usually start during the first 24 hours after birth. If this happens, you should contact a doctor and/or midwife immediately.
If you take Venlafaxine NORMON in the late stage 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 NORMON so they can advise you.
Venlafaxine NORMON 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 Venlafaxine NORMON treatment.
