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

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

Duloxetine is used in adults to treat:

• depression
• generalized anxiety disorder (a persistent feeling of anxiety or nervousness)
• diabetic neuropathic pain (often described as burning, shooting, stabbing, stinging, or like an electric shock. There may be loss of sensation in the affected area, or it may become sensitive to touch, heat, cold, or pressure)

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

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

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

Do not take Duloxetine Krka

• if you are allergic to duloxetine or any of the other ingredients of this medicine (listed in section 6)
• if you have liver failure
• if you have severe kidney disease
• if you are taking or have taken within the last 14 days another medicinal product called a monoamine oxidase inhibitor (MAOI) (see "Other medicines and Duloxetine Krka")
• if you are taking fluvoxamine, which is usually used to treat depression, ciprofloxacin or enoxacin, which are used to treat some infections
• if you are taking other medicines that contain duloxetine (see "Other medicines and Duloxetine Krka")

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

Warnings and precautions

Duloxetine may not be suitable for you due to the following reasons. Consult your doctor before you start taking this medicine if:

• you are using other medicines for depression, triptans, antipsychotics, buprenorphine. The use of these medicines with Duloxetine Krka may cause serotonin syndrome, a potentially life-threatening disease (see "Other medicines and Duloxetine Krka" and "Possible side effects")
• you are taking St. John's Wort, a herbal remedy (Hypericum perforatum)
• you have kidney disease
• you have had seizures (epileptic fits)
• you have had mania
• you have bipolar disorder
• you have eye problems, such as certain types of glaucoma (increased eye pressure)
• you have had bleeding problems (a tendency to develop bruises), especially if you are pregnant (see "Pregnancy and breast-feeding")
• you are at risk of having low sodium levels (e.g. if you are taking diuretics, especially if you are an elderly person)
• you are being treated with other medicines that may cause liver damage
• you are taking other medicines that contain duloxetine (see "Other medicines and Duloxetine Krka")

You should also tell your doctor:

If you experience signs and symptoms of agitation, hallucinations, loss of coordination, rapid heart rate, increased body temperature, rapid changes in blood pressure, overactive reflexes, diarrhea, coma, nausea, vomiting, as you may be suffering from serotonin syndrome.

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

Some medicines of the same group as Duloxetine Krka (called SSRIs/SNRIs) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms persist after stopping treatment.

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

Thoughts of suicide and worsening of your depression or anxiety disorder

If you are depressed and/or have an anxiety disorder, you may sometimes have thoughts of harming yourself or suicide. These thoughts may be increased at the start of treatment with antidepressants, as all these medicines take time to work, usually about two weeks, but sometimes longer.

It is more likely that you will have these thoughts if:

• you have previously had thoughts of self-harm or suicide
• you are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant

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

It may be 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 can ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behavior.

Children and adolescents under 18 years

Duloxetine should not normally be used in children and adolescents under 18 years. Also, you should know that patients under 18 years who take this type of medicine have an increased risk of side effects such as suicidal thoughts, suicidal attempts, and hostility (mainly aggression, oppositional behavior, and anger). Despite this, your doctor may prescribe duloxetine to patients under 18 years if they decide that it can be beneficial for the patient. If your doctor has prescribed duloxetine to a patient under 18 years and you want to discuss it, please go back to your doctor. You should tell your doctor if any of the above symptoms occur or worsen in patients under 18 years who are taking duloxetine. Also, in this age group, the long-term safety of duloxetine related to growth, maturation, and cognitive and behavioral development has not yet been demonstrated.

Other medicines and Duloxetine Krka

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription.

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

• diabetic neuropathic pain, depression, anxiety, and urinary incontinence

It should be avoided to use 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 obtained without a prescription, and herbal remedies, without talking to your doctor first.

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 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 an MAOI with many prescription medicines, including duloxetine, can cause serious side effects, even life-threatening. You should wait at least 14 days after stopping an MAOI before taking duloxetine. Similarly, you should wait at least 5 days after stopping duloxetine before starting an MAOI.

Medicines that cause drowsiness:These include medicines prescribed by your doctor, such as benzodiazepines, strong painkillers, antipsychotics, phenobarbital, and antihistamines.

Medicines that increase serotonin levels:Triptans, buprenorphine (a medicine to treat pain or addiction to opioids), 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), pethidine, St. John's Wort, and MAOIs (such as moclobemide and linezolid). These medicines increase the risk of side effects, such as serotonin syndrome (see "Warnings and precautions" and "Possible 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 blood clots. These medicines may increase the risk of bleeding.

Taking Duloxetine Krka with food, drinks, and alcohol

Duloxetine can be taken with or without food. You should be careful if you drink alcohol while being treated with duloxetine.

Pregnancy, breast-feeding, and fertility

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 if you are planning to become pregnant while taking duloxetine. You should only use duloxetine after discussing the potential benefits and risks with your doctor.

• Make sure your midwife and/or doctor know 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 faster and may turn blue. These symptoms usually start 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 near 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 of your baby's life. These symptoms include weakness, trembling, jitteriness, not feeding properly, breathing problems, and seizures. If your baby has any of these symptoms when it is born, or if you are worried about your baby's health, contact your doctor or midwife, who will be able to advise you.

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

• Data on the use of Duloxetine Krka during the first three months of pregnancy do not show an increased overall risk of birth defects in the baby. If you take Duloxetine Krka during the second half of pregnancy, there may be a greater risk that the baby will be born early (6 additional premature babies per 100 women taking Duloxetine Krka in the second half of pregnancy), especially between weeks 35 and 36 of pregnancy.

• Tell your doctor if you are breast-feeding. Duloxetine is not recommended during breast-feeding. Ask your doctor or pharmacist for advice.

Driving and using machines

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

Duloxetine Krka contains sucrose

If your doctor has told you that you have an intolerance to some sugars, consult your doctor before taking this medicine.

3. How to take Duloxetine Krka

Take this medicine exactly as your doctor or pharmacist has told you. If you are not sure, ask your doctor or pharmacist.

Duloxetine should be taken by mouth. You should swallow the capsule whole with water.

For depression and diabetic neuropathic pain:

The recommended dose of duloxetine is 60 mg once a day, but your doctor will prescribe the dose that is best for you.

For generalized anxiety disorder:

The usual starting dose of duloxetine 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 best for you. The dose may be adjusted up to 120 mg a day depending on your response to duloxetine.

To help you remember to take duloxetine, it may be helpful to take it at the same time every day.

Discuss with your doctor how long you should take duloxetine. Do not stop taking duloxetine, or change your dose, without talking to your doctor. It is important to treat your condition properly to help you improve. If your condition is not treated, it may not get better and may become more serious and more difficult to treat.

If you take more Duloxetine Krka than you should

If you have taken too much duloxetine, contact your doctor or pharmacist immediately or go to the emergency department at your nearest hospital. Take the medicine pack with you.

Symptoms of overdose include drowsiness, coma, serotonin syndrome (a rare reaction that can cause intense happiness, drowsiness, clumsiness, restlessness, feeling drunk, fever, sweating, or muscle stiffness), seizures, vomiting, and rapid heart rate.

If you forget to take Duloxetine Krka

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 a single dose as usual. Do not take a double dose to make up for a forgotten dose. Do not take more duloxetine than prescribed for you in one day.

If you stop taking Duloxetine Krka

Do not stop taking your capsules without talking to your doctor first, even if you feel better. If your doctor thinks you do not need to take duloxetine anymore, he or she will tell you how to reduce your dose over at least 2 weeks before stopping treatment.

Some patients who stop taking duloxetine have experienced symptoms such as:

• dizziness, tingling sensations like pins and needles or electric shock-like sensations (especially in the head), sleep disturbances (vivid dreams, nightmares, inability to sleep), fatigue, drowsiness, restlessness or agitation, anxiety, nausea or vomiting, tremor, headache, muscle pain, irritability, diarrhea, and excessive sweating or dizziness

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 other questions about the use of this medicine, ask your doctor or pharmacist.
