Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about DULOXETINE SANDOZ.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking DULOXETINE SANDOZ against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What DULOXETINE SANDOZ is used for

DULOXETINE SANDOZ belongs to a group of medicines called Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs). SNRIs are believed to work by their action on serotonin and noradrenaline in the brain.

Serotonin and noradrenaline are the chemical messengers responsible for controlling the psychological and painful physical symptoms of depression.

DULOXETINE SANDOZ is used to treat:

  • major depressive disorder (depression)
  • generalized Anxiety Disorder (excessive worry)

Ask your doctor if you have any questions about why DULOXETINE SANDOZ has been prescribed for you. Your doctor may have prescribed DULOXETINE SANDOZ for another reason.

DULOXETINE SANDOZ is available only with a doctor’s prescription.

DULOXETINE SANDOZ is not recommended for use in children and adolescents under the age of 18 years.


When you must not take it

Do not take DULOXETINE SANDOZ if you are allergic to any medicines containing duloxetine hydrochloride or any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue, or other parts of the body; rash, itching or hives on the skin.

Do not take DULOXETINE SANDOZ if you have liver disease. This could increase the chance of you having liver problems during treatment with DULOXETINE SANDOZ.

Do not take this medicine if you are taking another medicine for depression called a monoamine oxidase inhibitor (MAOI) or have been taking a MAOI within the last 14 days. Check with your doctor or pharmacist if you are unsure as to whether or not you are taking a MAOI.

If you do take DULOXETINE SANDOZ while you are taking a MAOI, you may experience shaking (tremor), shivering, muscle stiffness, fever, rapid pulse, rapid breathing and mental state from extreme agitation progressing to confusion and coma (a condition called serotonin syndrome).

Do not take DULOXETINE SANDOZ if you are taking another medicine that strongly interferes with how the liver works (potent CYP1A2 inhibitor). For example, another medicine for depression called fluvoxamine. Check with your doctor or pharmacist if you are unsure as to whether or not you are taking a potent CYP1A2 inhibitor.

Do not take DULOXETINE SANDOZ with thioridazine, a medicine used to treat schizophrenia.

Do not take DULOXETINE SANDOZ if the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

These symptoms usually begin immediately after the baby is born, or within a few days of birth, and should only last for a short time. If this happens to your baby, you should contact your doctor and/or midwife immediately.
