1. WHAT DUTOR IS AND WHAT IT IS USED FOR
Dutor contains the active substance duloxetine. Duloxetine increases the levels of serotonin and
noradrenaline in the nervous system.
Dutor is a medicine to treat Stress Urinary Incontinence (SUI) in women.
Stress urinary incontinence is a medical condition in which patients have accidental loss or leakage of
urine during physical exertion or activities such as laughing, coughing, sneezing, lifting, or exercise.
Dutor is believed to work by increasing the strength of the muscle that holds back urine when you laugh,
sneeze, or perform physical activities.
The efficacy of Dutor is reinforced when combined with a training program called Pelvic Floor Muscle
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE DUTOR
Do not take Dutor if you:
are allergic to duloxetine or any of the other ingredients of this medicine (listed in section 6).
have liver disease.
have severe kidney disease.
are taking or have taken within the last 14 days, another medicine known as a monoamine oxidase
inhibitor (MAOI) (see ‘Other medicines and Dutor’).
are taking fluvoxamine which is usually used to treat depression, ciprofloxacin or enoxacin which
are used to treat some infections.
Talk to your doctor if you have high blood pressure or heart disease. Your doctor will tell you if you
should be taking Dutor.
Warnings and precautions
The following are reasons why Dutor may not be suitable for you. Talk to your doctor before you take
Dutor if you:
are taking medicines to treat depression (see ‘Other medicines and Dutor’).
are taking St. John’s Wort, a herbal treatment (Hypericum perforatum).
have kidney disease.
have had seizures (fits).
have had mania.
suffer from bipolar disorder.
have eye problems, such as certain kinds of glaucoma (increased pressure in the eye).
have a history of bleeding disorders (tendency to develop bruises).
are at risk of low sodium levels (for example if you are taking diuretics, especially if you are
are currently being treated with another medicine which may cause liver damage.
The active substance of Dutor, duloxetine, is used in other medicines for other conditions:
diabetic neuropathic pain, depression, anxiety and urinary incontinence
Using more than one of these medicines at the same time should be avoided. Check with your doctor if
you are already taking other medicines containing duloxetine.
Dutor may cause a sensation of restlessness or an inability to sit or stand still. You should tell your doctor
if this happens to you.
Thoughts of suicide and worsening of depression or anxiety disorder
Although Dutor is not indicated for the treatment of depression, its active substance (duloxetine) is used
as an antidepressant medicine. If you are depressed and/or have anxiety disorders you can sometimes
have thoughts of harming or killing yourself. These may be increased when first starting antidepressants,
since these medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this if you:
- have previously had thoughts about killing or harming yourself
- are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour
in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a
hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder,
and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety
is getting worse, or if they are worried about changes in your behaviour.
Children and adolescents under 18 years of age
Dutor should normally not be used for children and adolescents under 18 years. Also, you should know
that patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and
hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of
medicines. Also, the long-term safety effects concerning growth, maturation, and cognitive and
behavioural development of Dutor in this age group have not yet been demonstrated.
Other medicines and Dutor
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines,
including medicines obtained without a prescription.
Your doctor should decide whether you can take Dutor with other medicines. Do not start or stop taking
any medicines, including those bought without a prescription and herbal remedies, before checking
with your doctor.
You should also tell your doctor if you are taking any of the following:
Monoamine oxidase inhibitors (MAOIs):
You should not take Dutor if you are taking, or have recently taken (within the last 14 days) an
antidepressant medicine called a monoamine oxidase inhibitor (MAOI). Examples of MAOIs include
moclobemide (an antidepressant) and linezolid (an antibiotic). Taking a MAOI together with Dutor, can
cause serious or even life-threatening side effects. You must wait at least 14 days after you have stopped
taking an MAOI before you can take Dutor. Also, you need to wait at least 5 days after you stop taking
Dutor before you take a MAOI.
Medicines that cause sleepiness:
These include medicines prescribed by your doctor including benzodiazepines, strong painkillers,
antipsychotics, phenobarbital and sedative antihistamines.
Medicines that increase the level of serotonin:
Triptans, tramadol, tryptophan, SSRIs (such as paroxetine and fluoxetine), SNRIs (such as venlafaxine),
tricyclic antidepressants (such as clomipramine, amitriptyline), pethidine, St John’s Wort and MAOIs
(such as moclobemide and linezolid). These medicines increase the risk of side effects; if you get any
unusual symptom taking any of these medicines together with Dutor, you should see your doctor.
Oral anticoagulants or antiplatelet medicines:
Medicines which thin the blood or prevent the blood from clotting. These medicines might increase the
risk of bleeding.
Dutor with food, drink and alcohol
Care should be taken if you drink alcohol while you are being treated with Dutor.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your
doctor or pharmacist for advice before taking this medicine.
Tell your doctor if you become pregnant, or you are trying to become pregnant, while you are taking
Dutor. You should use Dutor only after discussing the potential benefits and any potential risks to
your unborn child with your doctor.
Make sure your midwife and/or doctor knows you are on Dutor. When taken during pregnancy,
similar medicines (SSRIs) may increase the risk of a serious condition in babies, called persistent
pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish.
These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your
baby you should contact your midwife and/or doctor immediately.
If you take Dutor near the end of your pregnancy, your baby might have some symptoms when it is
born. These usually begin at birth or within a few days of your baby being born. These symptoms
may include floppy muscles, trembling, jitteriness, not feeding properly, trouble with breathing and
fits. If your baby has any of these symptoms when it is born, or you are concerned about your baby’s
health, contact your doctor or midwife who will be able to advise you.
Tell your doctor if you are breast-feeding. The use of Dutor while breastfeeding is not recommended.
You should ask your doctor or pharmacist for advice.
Driving and using machines
Dutor may make you feel sleepy or dizzy. Do not drive or use any tools or machines until you know how
Dutor affects you.
Dutor contains sucrose
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor
before taking this medicine.
HOW TO TAKE DUTOR
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
The recommended dose of Dutor is 40 mg twice a day (in the morning and late afternoon/evening). Your
doctor may decide to start your treatment with 20 mg twice a day for two weeks before increasing the
dose to 40 mg twice a day.
Dutor is for oral use. You should swallow your capsule whole with a drink of water. Dutor may be taken
with or without food.
To help you remember to take Dutor, you may find it easier to take it at the same times every day.
Do not stop taking Dutor, or change your dose, without talking to your doctor. Treating your disorder
properly is important to help you get better. If it is not treated, your condition may not go away and may
become more serious and difficult to treat.
If you take more Dutor than you should
Call your doctor or pharmacist immediately if you take more than the amount of Dutor prescribed by your
doctor. Symptoms of overdose include sleepiness, coma, serotonin syndrome (a rare reaction which may
cause feelings of great happiness, drowsiness, clumsiness, restlessness, feeling of being drunk, fever,
sweating or rigid muscles), fits, vomiting and fast heart rate.
If you forget to take Dutor
If you miss a dose, take it as soon as you remember. However, if it is time for your next dose, skip the
missed dose and take only a single dose as usual. Do not take a double dose to make up for a forgotten
dose. Do not take more than the daily amount of Dutor that has been prescribed for you in one day.
If you stop taking Dutor
DO NOT stop taking your capsules without the advice of your doctor even if you feel better. If your
doctor thinks that you no longer need Dutor he or she will ask you to reduce your dose over 2 weeks.
Some patients who suddenly stop taking Dutor after more than 1 week of therapy have had symptoms
dizziness, tingling feelings like pins and needles or electric shock-like feelings (particularly in the
head), sleep disturbances (vivid dreams, nightmares, inability to sleep), fatigue, sleepiness,
feeling restless or agitated, feeling anxious, feeling sick (nausea) or being sick (vomiting),
shaking (tremor), headaches, muscle pain, feeling irritable, diarrhoea, excessive sweating or
