1. What Venlafaxine 37.5 mg is and what it is used for

Venlafaxine 37.5 mg 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. It is not fully understood how antidepressants work, but they may help by increasing the levels of serotonin and noradrenaline in the brain.

Venlafaxine 37.5 mg 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 37.5 mg Do not take Venlafaxine 37.5 mg

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

•    If 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 37.5 mg, can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop taking Venlafaxine 37.5 mg before you take any MAOI (see also the sections “Serotonin syndrome” and “ Other medicines and Venlafaxine 37.5 mg”).

Warnings and precautions

Talk to your doctor or pharmacist before taking Venlafaxine 37.5 mg

•    If you use other medicines that taken together with Venlafaxine 37.5 mg could increase the risk of developing serotonin syndrome (see the section “Other medicines and Venlafaxine 37.5 mg").

•    If you have eye problems, such as certain kinds 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 told you have an abnormal heart rhythm.

•    If you have a history of fits (seizures).

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

•    If you 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).

•    If your cholesterol levels get higher.

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

•    If you have a history of aggressive behaviour.

•    If you have diabetes.

Venlafaxine 37.5 mg 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 you first start taking 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 yourself 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 10% of patients treated with venlafaxine. This may increase the risk of tooth decay (caries). Therefore, you should take special care in your dental hygiene.

Diabetes

Your blood glucose levels may be altered due to Venlafaxine 37.5 mg. Therefore, the dosage of your diabetes medicines may need to be adjusted.

Children and adolescents

Venlafaxine 37.5 mg 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 this medicine for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed this medicine 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 37.5 mg. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural development of this medicine in this age group has not yet been demonstrated.
