Venlafaxine Krka contains the active substance venlafaxine.
Venlafaxine Krka 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 Krka is a treatment for adults with depression.
Venlafaxine Krka is also a treatment for adults with the following anxiety disorders: generalised anxiety disorder, social anxiety disorder (fear or avoidance of social situations) and panic disorder (panic attacks). Treating depression or anxiety disorders 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.
Warnings and precautions Talk to your doctor or pharmacist before taking Venlafaxine Krka:
Venlafaxine Krka 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 thoughts may be increased when you first start taking antidepressants, since these medicines all take time to work, usually about two weeks, but sometimes longer. These thoughts may also occur when your dose is decreased or during discontinuation of treatment with Venlafaxine Krka.
You may be more likely to think like this:
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.
