1. What Duloxetine Zentiva is and what it is used for

Duloxetine Zentiva contains the active substance duloxetine. Duloxetine Zentiva increases the levels of serotonin and noradrenaline in the nervous system.

Duloxetine Zentiva is used in adults to treat:

• depression;
• generalised anxiety disorder (chronic feeling of anxiety or nervousness);
• diabetic neuropathic pain (often described as burning, stabbing, stinging, shooting or aching or like an electric shock. There may be loss of feeling in the affected area, or sensations such as touch, heat, cold or pressure may cause pain).

Duloxetine Zentiva starts to work in most people with depression or anxiety within two weeks of starting treatment, but it may take 2–4 weeks before you feel better. Tell your doctor if you do not start to feel better after this time. Your doctor may continue to give you Duloxetine Zentiva when you are feeling better to prevent your depression or anxiety from returning.

In people with diabetic neuropathic pain it can take some weeks before you feel better. Talk to your doctor if you do not feel better after 2 months.

2. What you need to know before you take Duloxetine Zentiva

Do not take Duloxetine Zentiva 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 Duloxetine Zentiva’);
• are taking fluvoxamine which is usually used to treat depression, ciprofloxacin or enoxacin which are used to treat some infections.

are taking other medicines containing duloxetine (see ‘Other medicines and Duloxetine Zentiva’)

Talk to your doctor if you have high blood pressure or heart disease. Your doctor will tell you if you should be taking Duloxetine Zentiva.

Warnings and precautions

The following are reasons why Duloxetine Zentiva may not be suitable for you. Talk to your doctor before taking Duloxetine Zentiva if you:

• are taking other medicines to treat depression (see ‘Other medicines and Duloxetine Zentiva’);
• 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), especially if you are pregnant (see ‘Pregnancy and breast-feeding‘);
• are at risk of low sodium levels (for example if you are taking diuretics, especially if you are elderly);
• are currently being treated with another medicine which may cause liver damage;
• are taking any opioid medicines such as buprenorphine containing medicine, tramadol and pethidine. The use of these medicines together with Duloxetine Zentiva can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Duloxetine Zentiva”);
• are taking other medicines containing duloxetine (see ‘Other medicines and Duloxetine Zentiva’).

Duloxetine Zentiva may cause a sensation of restlessness or an inability to sit or stand still. You should tell your doctor if this happens to you.

Medicines like Duloxetine Zentiva (so called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have continued after stopping treatment.

Thoughts of suicide and worsening of your depression or anxiety disorder

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

Duloxetine Zentiva 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. Despite this, your doctor may prescribe Duloxetine Zentiva for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed Duloxetine Zentiva for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking Duloxetine Zentiva. Also, the long-term safety effects concerning growth, maturation, and cognitive and behavioural development of duloxetine in this age group have not yet been demonstrated.

Other medicines and Duloxetine Zentiva

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The main ingredient of Duloxetine Zentiva, 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.

Your doctor should decide whether you can take Duloxetine Zentiva 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 Duloxetine Zentiva if you are taking, or have recently taken (within the last 14 days) another antidepressant medicine called a monoamine oxidase inhibitor (MAOI). Examples of MAOIs include moclobemide (an antidepressant) and linezolid (an antibiotic). Taking a MAOI together with many prescription medicines, including Duloxetine Zentiva, 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 Duloxetine Zentiva. Also, you need to wait at least 5 days after you stop taking Duloxetine Zentiva before you take a MAOI.
• Medicines that cause sleepiness: These include medicines prescribed by your doctor including benzodiazepines, strong painkillers, antipsychotics, phenobarbital and antihistamines.
• Medicines that increase the level of serotonin: Triptans, tryptophan, SSRIs (such as paroxetine and fluoxetine), SNRIs (such as venlafaxine), tricyclic antidepressants (such as clomipramine, amitriptyline), St. John’s Wort, MAOIs (such as moclobemide and linezolid) and opioid medicines such as buprenorphine containing medicine, tramadol and pethidine. These medicines increase the risk of side effects such as serotonin syndrome (see section “Warnings and precautions”). If you get any unusual symptom taking any of these medicines together with Duloxetine Zentiva, you should see your doctor.
• Oral anticoagulants or antiplatelet agents: Medicines which thin the blood or prevent the blood from clotting. These medicines might increase the risk of bleeding.

Duloxetine Zentiva with food, drink and alcohol

Duloxetine Zentiva may be taken with or without food. Care should be taken if you drink alcohol while you are being treated with Duloxetine Zentiva.

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 Duloxetine Zentiva. You should use Duloxetine Zentiva 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 Duloxetine Zentiva. When taken during pregnancy, similar drugs (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 Duloxetine Zentiva 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.
• If you take Duloxetine Zentiva near the end of your pregnancy there is an increased risk of excessive vaginal bleeding shortly after birth, especially if you have a history of bleeding disorders. Your doctor or midwife should be aware that you are taking duloxetine so they can advise you.
• Available data from the use of duloxetine during the first three months of pregnancy do not show an increased risk of overall birth defects in general in the child. If duloxetine is taken during the second half of pregnancy, there may be an increased risk that the infant will be born early (6 additional premature infants for every 100 women who take duloxetine in the second half of pregnancy), mostly between weeks 35 and 36 of pregnancy.
• Tell your doctor if you are breast-feeding. The use of Duloxetine Zentiva while breast-feeding is not recommended. You should ask your doctor or pharmacist for advice.

Driving and using machines

Duloxetine Zentiva may make you feel sleepy or dizzy. Do not drive or use any tools or machines until you know how Duloxetine Zentiva affects you.

Duloxetine Zentiva contains sucrose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take Duloxetine Zentiva

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Duloxetine Zentiva is for oral use. You should swallow your capsule whole with a drink of water.

For depression and diabetic neuropathic pain:

The usual dose of Duloxetine Zentiva is 60 mg once a day, but your doctor will prescribe the dose that is right for you.

For generalised anxiety disorder:

The usual starting dose of Duloxetine Zentiva is 30 mg once a day after which most patients will receive 60 mg once a day, but your doctor will prescribe the dose that is right for you. The dose may be adjusted up to 120 mg a day based on your response to Duloxetine Zentiva.

To help you remember to take Duloxetine Zentiva, you may find it easier to take it at the same times every day.

Talk with your doctor about how long you should keep taking Duloxetine Zentiva. Do not stop taking Duloxetine Zentiva, 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 Duloxetine Zentiva than you should

Call your doctor or pharmacist immediately if you take more than the amount of Duloxetine Zentiva 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 Duloxetine Zentiva

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 Duloxetine Zentiva that has been prescribed for you in one day.

If you stop taking Duloxetine Zentiva

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 Duloxetine Zentiva he or she will ask you to reduce your dose over at least 2 weeks before stopping treatment altogether.

Some patients who stop taking Duloxetine Zentiva suddenly have had symptoms such as:

• 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 vertigo.

These symptoms are usually not serious and disappear within a few days, but if you have symptoms that are troublesome you should ask your doctor for advice.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
