What this medicine is used for

Duloxetine is used to treat:
major depressive disorder (MDD)
generalised anxiety disorder (GAD) - excessive worry
Duloxetine 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 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 this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine should not be used in children and adolescents under the age of 18 years.

Before you take this medicine

Do not take this medicine if you have an allergy to:
any medicine containing duloxetine
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 this medicine if you have or have had liver disease.
Do not take this medicine if you are taking any medicine called a monoamine oxidase inhibitor (MAOI) (including moclobemide which is a reversible MAOI (RIMA)) or have been taking a MAOI within the last 14 days.
If you take duloxetine while you are taking a MAOI, you may experience shaking (tremor), shivering, muscle stiffness, fever, rapid pulse, rapid breathing or confusion.
Do not take this medicine if you are taking a medicine that is a potent inhibitor of CYP1A2, such as fluvoxamine or ciprofloxacin.
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 of the following medical conditions:
glaucoma (an eye disease where the fluid pressure in the eye may be high)
high blood pressure
heart problems
kidney problems
history of fits (seizures)
diabetes
you, or members of your family, have experienced bipolar disorder, depression or suicide
Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding.
Do not take this medicine whilst pregnant until you and your doctor have discussed the risks and benefits involved.
If duloxetine is taken during pregnancy, you should be careful, particularly at the end of pregnancy. Transitory withdrawal symptoms have been reported rarely in the newborn after maternal use in the last 3 months of pregnancy.
Tell your doctor if you are breastfeeding or plan to breastfeed.
Do not take this medicine whilst breastfeeding until you and your doctor have discussed the risks and benefits involved.
Duloxetine passes into breast milk and there is a possibility that your baby may be affected.
Tell your doctor if you drink alcohol.
People who drink excessive amounts of alcohol should not take duloxetine. Drinking too much alcohol could increase the risk of liver problems during treatment with duloxetine.
If you have not told your doctor about any of the above, tell them before you start taking this medicine.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and duloxetine may interfere with each other. These include:
monoamine oxidase inhibitors (MAOIs), medicines used to treat some types of depression.
You must stop taking MAOIs at least two weeks before starting duloxetine.
You must stop taking duloxetine at least 5 days before you start taking a MAOI
other medicines used to treat depression, panic disorder, anxiety or obsessive illnesses, including tryptophan
strong painkillers such as tramadol or pethidine
a type of migraine treatment called 'triptans', such as sumatriptan or zolmitriptan
medicines used to treat stress urinary incontinence such as tolteridone
medicines used to treat heart problems such as flecainide or propafenone
thioridazine, used to treat schizophrenia
herbal medicines such as St John's Wort (Hypericum perforatum)
warfarin, used to thin the blood (anticoagulant) or other medicines known to affect blood coagulation (NSAIDs or aspirin)
These medicines may be affected by duloxetine or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the directions, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how much of this medicine you should take.
This will depend on your condition and whether you are taking any other medicines.
For major depressive disorder
The recommended dose is usually one 60mg capsule once daily.
For generalised anxiety disorder
The recommended dose is 30mg to 120mg, taken once daily.
You may be started on a lower dose to help reduce side effects. If you have severe kidney disease, the recommended starting dose is one 30mg capsule once daily.

How to take it

Swallow the capsule whole with a full glass of water.
Do not open the capsules and crush the pellets inside because the medicine may not work as well.

When to take it

Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine even if you feel well.
The length of treatment with duloxetine will depend on how quickly your symptoms improve. Most medicines of this type take time to work so don't be discouraged if you do not feel better right away. Although you may notice an improvement, continue taking your medicine for as long as your doctor tells you.
Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Symptoms of an overdose may include drowsiness, convulsions and vomiting. They may also include feeling confused, feeling restless, sweating, shaking, shivering, hallucinations, muscle jerks, or fast heartbeat.

While you are taking this medicine

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.

Tell your doctor immediately if you have any suicidal thoughts or other mental/mood changes.
Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide. These symptoms may continue or get worse during the first one or two months of treatment, until the full antidepressant effect of the medicine becomes apparent. This is more likely to occur in young adults under 25 years of age.
All mention of suicide or violence must be taken seriously. Contact your doctor or a mental health professional right away or go to the nearest hospital for treatment if you or someone you know is showing any of the following warning signs of suicide:
worsening of your depression
thoughts or talk of death or suicide

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
If you stop taking it suddenly, your condition may worsen, or you may have unwanted side effects. If possible, your doctor will gradually reduce the amount you take each day before stopping the medicine completely.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you.
Duloxetine may cause dizziness of drowsiness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Be careful when drinking alcohol while you are taking this medicine.
You should avoid 'binge drinking' or drinking excessively during treatment with duloxetine as it can cause severe liver injury.
