2. What you need to know before you take Edronax

Do not take Edronax

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

Warnings and cautions

Talk to your doctor or pharmacist before taking Edronax if you:

  • suffering from seizures or epilepsy. Treatment with Edronax should be discontinued if seizures occur.
  • have symptoms of urinary tract problems, enlarged prostate, or previously had heart problems.
  • Taking medications to lower your blood pressure.
  • have liver or kidney problems. Your doctor may need to adjust dose one.
  • take other antidepressants such as MAO inhibitors, tricyclic antidepressants, nefazodone, SSRIs (such as fluvoxamine), or lithium.
  • take other MAOIs such as linezolid (an antibiotic ) or methylene blue (see section “Other medicines and Edronax”)
  • previously had mania (overactive behavior or thoughts).
  • have eye problems such as certain types of glaucoma (increased pressure in the eye)

If you start to feel worse and have thoughts of harming yourself.

You who are depressed and/or suffer from worry/anxiety may sometimes have thoughts of harming yourself or committing suicide. These symptoms may worsen when you start using antidepressants, as it takes time for this type of medicine to take effect, usually about 2 weeks, sometimes longer.

These thoughts may be common:

  • if you have previously had thoughts of harming yourself or committing suicide
  • if you are younger than 25 years. Studies have shown that young adults (younger than 25 years) with mental illness who are treated with antidepressant drugs have an increased risk of suicidal thoughts and thoughts of harming themselves.

Contact a doctor as soon as possible or see the nearest hospital if you have thoughts of injuring yourself or committing suicide.

It may be helpful to tell a relative or close friend that you are depressed and/or suffering from anxiety. Feel free to ask them to read this leaflet. You can also ask them to tell you if they think you are feeling worse or if they think your behavior is changing.

Children and young people

Edronax should not normally be used in the treatment of children and adolescents under 18 years of age. The risk of side effects such as suicide attempts, suicidal thoughts, and hostility (mainly aggression, defiance, and anger) is greater in patients under 18 years of age when taking drugs of this type. Despite this, Edronax can be prescribed by a doctor to patients under 18 years of age, if the doctor deems it appropriate. If you are under 18 years of age and want to discuss why you were given this medicine, consult your doctor again.

You should also tell your doctor if you notice any of the above symptoms or if they get worse.

The long-term effects on growth, maturity, and cognitive and behavioral development have not yet been established for children and adolescents under 18 years of age.

  • Some antidepressants called MAO inhibitors, tricyclic antidepressants, nefazodone, SSRIs (such as fluvoxamine), or lithium
