Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about DULOXECOR. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

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

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

Keep this leaflet with the medicine. You may need to read it again.

What DULOXECOR is used for

DULOXECOR is used to treat major depressive disorder (depression), Diabetic Peripheral Neuropathic Pain (nerve pain caused by diabetes) and Generalised Anxiety Disorder (excessive worry)

DULOXECOR 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.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

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

Before you take DULOXECOR

When you must not take it

Do not take DULOXECOR if you have an allergy to:

  • any medicine containing duloxetine hydrochloride;
  • 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 DULOXECOR if you have liver disease. This could increase the chance of you having liver problems during treatment with DULOXECOR.

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 DULOXECOR 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 DULOXECOR 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 DULOXECOR with thioridazine, a medicine used to treat schizophrenia.

Do not take DULOXECOR if you are taking another medicine for depression called fluvoxamine.

Do not take this medicine after 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.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any medical conditions, especially if you have:

  • a condition in which the pressure of fluid in the eye may be high (glaucoma)
  • high blood pressure
  • heart problems
  • kidney problems as you may need to take a lower dose of DULOXECOR
  • history of fits (seizures)
  • bipolar disorder
  • bleeding/clotting disorders
  • diabetes

If you have high blood pressure or heart problems your doctor may monitor your blood pressure.

Tell your doctor if you are pregnant or plan to become pregnant. DULOXECOR should only be used in pregnancy if the potential benefits outweigh the potential risks.

Your doctor can discuss with you the risks and benefits involved.

When taken in the last 3 months of pregnancy, DULOXECOR may affect your newborn baby. They may experience symptoms such as irritability, constant crying, feeding difficulties, vomiting, fluctuating temperature, seizures, tremors, jitteriness, bluish appearance (cyanosis), breathing interruptions, wheezing or shallow breathing, low blood sugar, muscle stiffness, muscle weakness, or overresponsive reflexes, These symptoms are uncommon and may be due to the effect of DULOXECOR or the discontinuation of DULOXECOR.

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.

Taking DULOXECOR during pregnancy may increase the risk of pre-term birth. If you take DULOXECOR near the end of your pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after birth. Tell your doctor or midwife if you are taking DULOXECOR so that they can advise you.

Talk to your doctor if you are breastfeeding or intend to breastfeed. Breastfeeding while on DULOXECOR is not recommended.

Talk to your doctor about how much alcohol you drink. People who drink excessive amounts of alcohol should not take DULOXECOR. Drinking too much alcohol could increase the chance of you having liver problems during treatment with DULOXECOR.

If you have not told your doctor about any of the above, tell them before you start taking DULOXECOR.

Taking other medicines

  • monoamine oxidase inhibitors (MAOIs), medicines used to treat some types of depression.
    You should stop taking MAOIs at least two weeks before starting DULOXECOR.

  • medicines used to treat heart problems such as flecainide or propafenone
