venlafaxine

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:

• If you use other medicines that taken together with Venlafaxine Krka could increase the risk of developing serotonin syndrome (see the section “Other medicines and Venlafaxine Krka”).
• 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 pregnant (see Pregnancy, breast-feeding and fertility), 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 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 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.

Sexual dysfunction

Medicines like Venlafaxine Krka (so called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have continued after stopping treatment.

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 Krka. Therefore, the dosage of your diabetes medicines may need to be adjusted.

Children and adolescents

Venlafaxine Krka 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 Krka. 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.

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The usual recommended starting dose for treatment of depression, generalised anxiety disorder and social anxiety disorder is 75 mg per day. The dose can be raised by your doctor gradually, and if needed, even up to a maximum dose of 375 mg daily for depression. If you are being treated for panic disorder, your doctor will start with a lower dose (37.5 mg) and then increase the dose gradually. The maximum dose for generalised anxiety disorder, social anxiety disorder and panic disorder is 225 mg/day.

Take Venlafaxine Krka at approximately the same time each day, either in the morning or in the evening.

Capsules must be swallowed whole with fluid and not opened, crushed, chewed or dissolved.

Venlafaxine Krka should be taken with food.

If you have liver or kidney problems, talk to your doctor, since your dose of this medicine may need to be different.

Do not stop taking this medicine without talking to your doctor (see the section “If you stop taking Venlafaxine Krka”).

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
