1. What is Edronax and what is it used for

Edronax is indicated for the intensive treatment of depression (including its severe form) and for maintenance treatment in patients who have responded well to initial treatment.
Many chemical compounds present in the brain affect mood. Noradrenaline is one of these compounds. The concentration of noradrenaline in people with depression is low. Edronax contains reboxetine, which belongs to a group of medicines called selective noradrenaline reuptake inhibitors. Edronax enhances the action of noradrenaline in the central nervous system, thereby reducing the symptoms of its deficiency. It alleviates the symptoms of depression and improves mood, and reduces fatigue and anxiety.
Despite improvement, which usually occurs after a few weeks, do not stop taking Edronax without consulting your doctor. This will reduce the risk of recurrence of disease symptoms.

2. Important information before taking Edronax

When not to take Edronax

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

Warnings and precautions

Tell your doctor if you have any of the following conditions, as a dose change or selection of another medicine may be necessary:

• kidney or liver disease;
• seizures (epilepsy);
• glaucoma or increased eye pressure;
• urination difficulties, with or without prostate enlargement;
• low blood pressure;
• cardiovascular disease, such as hypertension, previous myocardial infarction;
• taking antidepressant medicines called "monoamine oxidase inhibitors" (MAOIs) or taking MAOIs in the last 2 weeks. Your doctor may advise you to stop taking MAOIs for at least 2 weeks before starting Edronax.

Serotonin syndrome:
Serotonin syndrome is a potentially life-threatening condition that may occur when taking Edronax alone or in combination with other medicines (see section 2 "Edronax and other medicines"). Symptoms of serotonin syndrome may include: confusion, restlessness, hallucinations, coma, rapid heartbeat, elevated body temperature, rapid changes in blood pressure, sweating, hot flashes, tremors, overreactivity, nausea, vomiting, and diarrhea.

You should contact your doctor or go to the emergency department of the nearest hospital immediately if you observe symptoms of serotonin syndrome.

Suicidal thoughts and worsening of depression or anxiety disorders

People suffering from depression and/or anxiety disorders may sometimes feel like hurting themselves or committing suicide. This may worsen after starting to take antidepressant medicines, as their effect develops over a period of time, usually appearing only after about two weeks of treatment, and sometimes later.
Such thoughts occur more frequently:

• in people who have already felt like hurting themselves or committing suicide in the past;
• in young people. Clinical trials have shown that the risk of suicidal behavior is higher in people under 25 years of age with mental disorders who have taken antidepressant medicines. If you feel like hurting yourself or committing suicide, you should immediately contact your doctor or go to the hospital. It's worth talking to your loved ones about depression or anxiety and asking them to read this leaflet. You can also ask them to pay attention to whether the symptoms of depression or anxiety are worsening and to assess whether changes in behavior are disturbing.
