1. What Xeristar is and what it is used for

Xeristar 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 chronic feeling of anxiety or nervousness)
• diabetic neuropathic pain (often described as burning, stabbing, shooting, tingling, or like an electric shock. There may be loss of sensation in the affected area, or pain may occur when the area is touched or exposed to heat, cold, or pressure)

Duloxetine begins to work in most people with depression or anxiety within two weeks of starting treatment, but it may take 2 to 4 weeks before you start to feel better. Inform your doctor if you do not notice improvement within this time. Your doctor may continue to give you duloxetine once you are feeling better to prevent your depression or anxiety from returning.

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

2. What you need to know before taking Xeristar

DO NOT take Xeristar:

• if you are allergic to duloxetine or any of the other ingredients of this medicine (listed in section 6)
• if you have hepatic insufficiency
• if you have severe renal insufficiency
• if you are taking or have taken within the last 14 days another medicine known as a monoamine oxidase inhibitor (MAOI) (see “Use of Xeristar with other medicines”)
• if you are taking fluvoxamine, which is normally used to treat depression, or ciprofloxacin or enoxacin, which are used to treat certain infections
• if you are taking other medicines containing duloxetine (see “Use of Xeristar with other medicines”)

Consult your doctor if you have high blood pressure or a heart condition. Your doctor will determine whether 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 using other medicines to treat depression (see “Use of Xeristar with other medicines”)
• you are taking St. John’s wort, a herbal remedy (Hypericum perforatum)
• you have any kidney disease
• you have experienced seizures (epileptic fits)
• you have experienced mania
• you suffer from bipolar disorder
• you have eye problems, such as certain types of glaucoma (increased intraocular pressure)
• you have had bleeding problems (tendency to bruise easily)

especially if you are pregnant (see “Pregnancy and breastfeeding”)

• you are at risk of low sodium levels (e.g., if you are taking diuretics, particularly if you are elderly)
• you are receiving treatment with other medicines that may cause liver damage
• you are taking other medicines containing duloxetine (see “Use of Xeristar with other medicines”)

Xeristar may cause a feeling of restlessness or inability to sit still or remain motionless. If this occurs, inform your doctor.

Some medicines in the same class as Xeristar (known as SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

Suicidal thoughts and worsening of depression or anxiety disorder

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

You are more likely to have such thoughts if:

• you have previously had thoughts of self-harm or suicide
• you are a young adult. Clinical trial data have shown an increased risk of suicidal behaviour in psychiatric patients under 25 years of age treated with antidepressants.

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

It may be helpful to inform a close family member or friend that you are depressed or have an anxiety disorder and ask them to read this leaflet. You may ask them to inform you if they notice your depression or anxiety worsening, or if they are concerned about changes in your behaviour.

You should also contact your doctor:

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

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

Children and adolescents under 18 years of age

Duloxetine should normally not be used in children and adolescents under 18 years of age. In addition, you should know that patients under 18 years of age taking this type of medicine have an increased risk of side effects such as suicide attempts, suicidal thoughts, and hostility (predominantly aggression, oppositional behaviour, and anger). Nevertheless, your doctor may prescribe duloxetine to patients under 18 years of age if they decide it may be beneficial for the patient. If your doctor has prescribed duloxetine to a patient under 18 years of age and you wish to discuss it, please return to your doctor. You must inform your doctor if any of the above symptoms appear or worsen in patients under 18 years of age taking duloxetine. Furthermore, in this age group, the long-term effects of duloxetine on growth, maturation, and cognitive and behavioural development have not yet been established.

Use of Xeristar with other medicines

Inform your doctor or pharmacist if you are currently using, have recently used, or might need to use any other medicines, including those obtained without a prescription.

The main component of Xeristar, 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 containing duloxetine.

Your doctor will decide whether 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 first consulting your doctor.

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

Monoamine oxidase inhibitors (MAOIs): You must not take duloxetine if you are currently taking, or have recently taken (within 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 an MAOI together with many prescription medicines, including duloxetine, can cause serious adverse effects and may even be life-threatening. You must wait at least 14 days after stopping treatment with an MAOI before starting duloxetine. Likewise, you must wait at least 5 days after stopping duloxetine before starting treatment with an MAOI.

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

Medicines that increase serotonin levels: Triptans, tramadol, tryptophan, selective serotonin reuptake inhibitors (SSRIs, such as paroxetine and fluoxetine), SNRIs (such as venlafaxine), tricyclic antidepressants (such as clomipramine, amitriptiline), meperidine, St. John’s wort, and MAOIs (such as moclobemide and linezolid). These medicines increase the risk of adverse effects; if you notice any unusual symptoms when using any of these medicines together with duloxetine, inform 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 Xeristar with food, drinks, and alcohol

Duloxetine can be taken with or without food. You should exercise caution if you consume alcohol while being treated with duloxetine.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, 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. Duloxetine should only be used after your doctor has evaluated the potential benefits and any potential risks to the fetus.

• 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 newborns called persistent pulmonary hypertension of the newborn (PPHN), which causes the baby to breathe faster and appear bluish. These symptoms usually begin within the first 24 hours after birth. If this happens to your baby, contact your midwife and/or doctor immediately.

• If you take duloxetine near the end of your pregnancy, your baby may experience certain symptoms after birth. These usually begin at birth or during the first few days after birth. Symptoms may include weak muscles, tremors, restlessness, poor feeding, breathing difficulties, and seizures. If your baby shows any of these symptoms after birth or if you are concerned about your baby’s health, contact your doctor or midwife, who can advise you.

• If you take duloxetine near the end of your pregnancy, there is an increased risk of excessive vaginal bleeding shortly after delivery, especially if you have had bleeding problems. Your doctor or midwife should be aware that you are taking duloxetine so they can advise you.

• 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. If you take duloxetine during the second half of pregnancy, there may be an increased risk of premature birth (6 additional premature babies per 100 women taking duloxetine in the second half of pregnancy), particularly between weeks 35 and 36 of pregnancy.

• Inform your doctor if you are breastfeeding. The use of duloxetine during breastfeeding is not recommended. Seek advice from your doctor or pharmacist.

Driving and using machines

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

Xeristar contains sucrose

This medicine contains sucrose. If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

3. How to take Xeristar

Follow exactly the instructions for using this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

Duloxetine should be taken orally. You must swallow the capsule whole with water.

For depression and diabetic neuropathic pain:

The recommended dose of duloxetine is 60 mg once daily, 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 daily, after which most patients will receive 60 mg once daily, but your doctor will prescribe the dose that is best for you. The dose may be adjusted up to 120 mg daily 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 consulting your doctor. It is important to treat your condition properly to help you improve. If left untreated, your condition may not resolve and could become more severe and more difficult to treat.

If you take more Xeristar than you should

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at: 91 562 04 20, indicating the medicine and the amount ingested.

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

If you forget to take Xeristar

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the usual time. Do not take a double dose to make up for a missed dose. Do not take more duloxetine than prescribed for you in one day.

If you stop taking Xeristar

DO NOT stop taking your capsules without consulting your doctor, even if you feel better. If your doctor decides that you no longer need to take duloxetine, they will advise you to gradually reduce your dose over at least 2 weeks before stopping treatment.

Some patients who stop duloxetine treatment suddenly have experienced symptoms such as:

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

These symptoms are usually not serious and disappear within a few days, but if you experience bothersome symptoms, seek advice from your doctor.

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