Leaflet: information for the user

Dulotex 60 mg gastro-resistant tablets

Duloxetine (hydrochloride)

Read this leaflet carefully before you start taking this medicine, because it contains important information for you.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, consult your doctor or pharmacist.
• This medicine has been prescribed for you only. Do not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor or pharmacist, even if they are not listed in this leaflet. See section 4.

Dulotex contains the active ingredient duloxetina. Duloxetina increases the levels of serotonin and noradrenaline in the nervous system.

Dulotex is used in adults to treat:

• Depression
• Generalized anxiety disorder (chronic sensation of anxiety or nervousness)
• Diabetic neuropathic pain (often described as burning, stabbing, pinching, stinging, or electric shock-like pain. There may be a loss of sensation in the affected area, or pain may occur when touching the area or exposing it to heat, cold, or pressure).

Dulotex begins to take effect in most people with depression or anxiety within two weeks of starting treatment, but it may take between 2 and 4 weeks to start feeling better. Inform your doctor if you do not notice improvement after this time. Your doctor may continue giving you Dulotex when you are feeling better to prevent your depression or anxiety from returning.

In people with diabetic neuropathic pain, it may take several weeks to start feeling better. Consult your doctor if you do not feel better after 2 months.

Do not take Dulotex if:

• You are allergic to duloxetine or any of the other ingredients in this medicine (listed in section 6)
• You have liver failure
• You have severe kidney failure
• You are taking or have taken in the last 14 days another medicine known as a monoamine oxidase inhibitor (MAOI) (see “Taking Dulotex with other medicines”)
• You are taking fluvoxamine, which is usually used to treat depression, ciprofloxacin or enoxacin, which are used in the treatment of some infections
• You are taking other medicines that contain duloxetine (see “Taking Dulotex with other medicines”)

Consult your doctor if you have high blood pressure or a heart condition. Your doctor will tell you if you should take duloxetine.

Warnings and precautions

Duloxetine may not be suitable for you for the following reasons.

Consult your doctor before starting to take this medicine if:

• You are taking other medicines to treat depression (see “Taking Dulotex with other medicines”)
• You are taking St. John's Wort, a herbal remedy (Hypericum perforatum)
• You have any kidney disease
• You have had seizures (epileptic fits)
• You have had mania
• You have bipolar disorder
• You have eye problems, such as some types of glaucoma (increased eye pressure)
• You have a tendency to develop bleeding problems, especially if you are pregnant (see “Pregnancy and breastfeeding”)
• You have a risk of low sodium levels (for example if you are taking diuretics, especially if you are an older person).
• You are being treated with other medicines that can damage the liver
• You are taking other medicines that contain duloxetine (see “Taking Dulotex with other medicines”)

Duloxetine may cause a feeling of restlessness or inability to sit still. If this happens, tell your doctor.

You should also contact your doctor:

If you experience signs and symptoms of restlessness, hallucinations, loss of coordination, rapid heartbeat, increased body temperature, rapid changes in blood pressure, hyperactive reflexes, diarrhoea, coma, nausea, vomiting, as you may be suffering from a serotonin syndrome.

In its most severe form, serotonin syndrome may resemble Neuroleptic Malignant Syndrome (NMS). The signs and symptoms of NMS may include a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by blood test).

Some medicines in the group to which Dulotex belongs (called SSRIs/SNRIs) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms persist after stopping treatment.

Thoughts of suicide and worsening of depression or anxiety

If you are depressed and/or have anxiety disorders, you may occasionally have thoughts of self-harm or suicide. These thoughts may be increased at the beginning of treatment with antidepressants, as all these medicines take time to work, usually two weeks but sometimes longer.

You are more likely to have these thoughts if:

• You have had thoughts of self-harm or suicide before
• You are a young adult. There is information from clinical trials that has shown an increased risk of suicidal behaviour in adults under 25 years old who have a psychiatric disorder and are being treated with antidepressants.

Contact your doctor or go directly to the hospital immediately if you have any thoughts of self-harm or suicide.

It may be helpful to tell a close friend or family member that you are depressed or have an anxiety disorder, and ask them to read this leaflet. They may be able to tell you if your depression or anxiety is getting worse, or if they are concerned about changes in your behaviour.

Children and adolescents under 18 years

Duloxetine is usually not used in children and adolescents under 18 years old. You should also know that patients under 18 years old who take this class of medicines have an increased risk of side effects such as suicidal thoughts, suicidal behaviour and hostility (mainly aggression, oppositional behaviour and irritability). Despite this, your doctor may prescribe duloxetine to patients under 18 years old because they decide it may be beneficial for the patient. If your doctor has prescribed duloxetine to a patient under 18 years old and you want to talk about it, please go back to your doctor. You should tell your doctor if any of the symptoms above appear or get worse in patients under 18 years old who are taking duloxetine. Also, in this age group, the long-term safety effects of duloxetine related to growth, maturation and development of cognitive and behavioural functions have not yet been demonstrated.

Taking Dulotex with other medicines

Inform your doctor or pharmacist if you are using, have used recently or may need to take any other medicine, including those bought without a prescription.

The main component of Dulotex, duloxetine, is used in other medicines for other treatments:

• diabetic neuropathic pain, depression, anxiety and urinary incontinence

You should avoid using more than one of these medicines at the same time. Check with your doctor if you are already using other medicines that contain duloxetine.

Your doctor will decide if you can take duloxetine with other medicines.Do not start or stop taking any medicine, including those bought without a prescription and herbal remedies, without first consulting your doctor.

You should also tell your doctor if you are taking any of the following medicines:

Monoamine oxidase inhibitors (MAOIs):You should not take duloxetine if you are taking, or have taken in the last 14 days, another antidepressant medicine known as a monoamine oxidase inhibitor (MAOI). Examples of MAOIs include moclobemide (an antidepressant) and linezolid (an antibiotic). Taking a MAOI with many prescription medicines, including duloxetine, can cause serious side effects, even life-threatening. You should wait at least 14 days after stopping treatment with a MAOI before taking duloxetine. Similarly, you should wait at least 5 days after stopping treatment with duloxetine before starting treatment with a MAOI.

Medicines that cause drowsiness:This includes prescription medicines prescribed by your doctor such as benzodiazepines, powerful analgesics, antipsychotics, phenobarbital and antihistamines.

Medicines that increase serotonin levels: Triptans, tramadol, tryptophan, selective serotonin reuptake inhibitors (SSRIs, such as paroxetine and fluoxetine), serotonin-norepinephrine reuptake inhibitors (SNRIs, such as venlafaxine), tricyclic antidepressants (such as clomipramine, amitriptyline), petidin, St. John's Wort and MAOIs (such as moclobemide and linezolid). These medicines increase the risk of side effects; if you notice any unusual symptoms when using any of these medicines with duloxetine, you should tell your doctor.

Oral anticoagulants or antiplatelet agents:Medicines that thin the blood or prevent the formation of blood clots in the blood. These medicines may increase the risk of bleeding.

Taking Dulotex with food, drink and alcohol

Duloxetine can be taken with or without food. You should be careful if you take alcohol while taking duloxetine.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, or think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

• Inform your doctor if you become pregnant or are trying to become pregnant while taking duloxetine. You should only use duloxetine after discussing the potential benefits and any potential risks to the foetus with your doctor.

• Make sure your midwife and/or doctor know that you are taking duloxetine. Other similar medicines (SSRIs), taken during pregnancy, may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), which makes the baby breathe more rapidly and turn blue. These symptoms usually start within the first 24 hours after the baby's birth. If this happens to your baby, you should contact your midwife and/or doctor immediately.

• If you take duloxetine towards the end of your pregnancy, your baby may have some symptoms when it is born. These usually start at birth or within the first few days after the baby's birth. These symptoms may include weak muscles, trembling, restlessness, that the baby does not feed properly, breathing problems and convulsions. If your baby has any of these symptoms when it is born or if you are concerned about your baby's health, contact your doctor or midwife, who can advise you.

• If you take duloxetine towards the end of your pregnancy, there is a higher risk of excessive vaginal bleeding after birth, especially if you have had bleeding problems. Your doctor or midwife should know that you are taking duloxetine so they can advise you.

• The available data on the use of duloxetine during the first three months of pregnancy do not show a general increase in the risk of birth defects in the baby. If you take duloxetine during the second half of pregnancy, there may be a higher risk of the baby being born prematurely (6 extra premature births per 100 women taking duloxetine in the second half of pregnancy), especially between weeks 35 and 36 of pregnancy.

• Inform your doctor if you are breastfeeding. Duloxetine is not recommended during breastfeeding. Ask your doctor or pharmacist for advice.

Driving and operating machines

During treatment with duloxetine, you may feel drowsy or dizzy. Do not drive or operate tools or machines until you know how duloxetine affects you.

If you forgot to take Dulotex

If you forget to take a dose, take it as soon as you remember. However, if it is time for the next dose, skip the missed dose and take a single dose as you normally do. Do not take a double dose to compensate for the missed doses. Do not take more duloxetine than prescribed for you in a day.

If you interrupt treatment with Dulotex

DO NOT stop taking your tablets without your doctor's advice, even if you feel better. If your doctor thinks you no longer need to take duloxetine, they will instruct you to reduce your dose for at least 2 weeks before stopping treatment.
