Pack contents and additional information

1. What duloxetina cinfa is and what it is used for

duloxetina cinfa 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 (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 after starting treatment, but it may take between 2 and 4 weeks before you start to feel better. Inform your doctor if you do not notice any improvement by this time. Your doctor may continue your duloxetine treatment once you feel 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 duloxetine cinfa

Do not take duloxetine cinfa if:

• you are allergic to duloxetine or to any of the other ingredients of this medicine (listed in section 6)
• you have hepatic impairment
• you have severe renal impairment
• you are taking or have taken within the last 14 days another medicine known as a monoamine oxidase inhibitor (MAOI) (see "Taking duloxetine cinfa with other medicines")
• you are taking fluvoxamine, which is normally used to treat depression, or ciprofloxacin or enoxacin, which are used to treat certain infections
• you are taking other medicines containing duloxetine (see "Taking duloxetine cinfa 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 or pharmacist before starting to take duloxetine cinfa if:

• you are using other medicines to treat depression (see "Taking duloxetine cinfa 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 experienced mania
• you suffer from bipolar disorder
• you have eye problems, such as certain types of glaucoma (increased eye 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 "Taking duloxetine cinfa with other medicines")

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

Some medicines in the same class as duloxetine cinfa (called SSRIs/SNRIs) may cause sexual dysfunction symptoms (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 have anxiety disorders, you may occasionally experience thoughts of self-harm or suicide. These thoughts may increase at the beginning of treatment with antidepressants, as all these medicines take time to become effective, 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 directly to hospital immediately 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 tell 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, diarrhoea, coma, nausea, 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 a 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 this, please return to your doctor. You must inform your doctor if any of the symptoms listed above 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.

Taking duloxetine cinfa with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicine.

The main component of duloxetine cinfa, 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 over-the-counter medicines 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 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 causing drowsiness: this includes medicines prescribed by your doctor such as benzodiazepines, strong painkillers, antipsychotics, phenobarbital, and antihistamines.

Medicines increasing serotonin levels: triptans, tramadol, tryptophan, selective serotonin reuptake inhibitors (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 adverse effects; if you notice any unusual symptoms when using any of these medicines together with duloxetine, you must inform your doctor.

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

Taking duloxetine cinfa 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 and breastfeeding

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

• Ensure that your midwife and/or doctor know that you are taking this medicine. 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 develop a bluish colouration. These symptoms usually begin within the first 24 hours after birth. If this occurs in 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, irritability, poor feeding, breathing difficulties, and seizures. If your baby has 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 appropriately.

• 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.

duloxetine cinfa contains sucrose.

This medicine contains sucrose. If your doctor has diagnosed you with an intolerance to certain sugars, consult with them before taking this medicine.

3. How to take duloxetine cinfa

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

Duloxetine should be taken orally. 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 worse and more difficult to treat.

If you take more duloxetine cinfa than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number 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 well-being, drowsiness, clumsiness, restlessness, feeling drunk, fever, sweating, or muscle rigidity), seizures, vomiting, and rapid heart rate.

If you forget to take duloxetine cinfa

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 the next dose at your usual time. Do not take a double dose to make up for forgotten doses. Do not take more duloxetine than prescribed for you in one day.

If you stop taking duloxetine cinfa

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 continue taking duloxetine, they will instruct you to gradually reduce your dose over at least 2 weeks before stopping treatment.

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

• dizziness, tingling sensations like pins and needles or electric shocks (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.
