6.Contents of thepackage and additional information

Duloxetina TecniGen contains the active ingredient duloxetina. Duloxetinaincreases the levels of serotoninand noradrenaline in the nervous system.

Duloxetina is used in adults to treat:

• depression
• generalized anxiety disorder (chronic feeling 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 the area is touched or comes into contact with heat, cold, or pressure)

Duloxetina 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 to give you duloxetina 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 Duloxetina TecniGen:

• 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 failure
• if you are taking or have taken in the last 14 days another medicine known as a monoamine oxidase inhibitor (MAOI) (see “Duloxetina TecniGen use with other medicines”)
• 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 “Duloxetina TecniGen use with other medicines”)

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 for the following reasons. Consult your doctor before starting to take this medicine if:

• you are taking other medicines to treat depression (see “Duloxetina TecniGen use with other medicines”)
• you are taking St. John's Wort, a herbal treatment (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
• you are at risk of having 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 “Duloxetina TecniGen use with other medicines”)

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

Thoughts of suicide and worsening of depression or anxietyIf you are depressed or have anxiety disorders, you may occasionally have thoughts of self-harm or suicide. These thoughts may be increased when you start taking antidepressants, as all these medicines take time to work, usually two weeks but sometimes longer.

It is more likely that you will 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 people under 25 years old who have a psychiatric disorder and are being treated with antidepressants.

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

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 anxiety disorders, 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

Duloxetine should not normally be used in children and adolescents under 18 years old. You should also know that patients under 18 years old who take this type of medicine 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 for patients under 18 years old because they decide it may be beneficial for the patient. If your doctor has prescribed duloxetine for a patient under 18 years old and you want to talk about it, please go back to the doctor. You should tell your doctor if any of the symptoms mentioned 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.

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).

Use ofDuloxetina TecniGenwith other medicines

Inform your doctor or pharmacist if you are using, have used recently or may have to take any other medicine.

The main component of Duloxetina TecniGen, 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:

MAOIs:You should not take duloxetine if you are taking, or have taken in the last 14 days, another antidepressant known as a monoamine oxidase inhibitor (MAOI). For example, 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 treatment with an MAOI before taking duloxetine. Similarly, you should wait at least 5 days after stopping treatment with duloxetine before starting treatment with an 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 and amitriptyline), pethidine, 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 taking any of these medicines with duloxetine, 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.

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 disease 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, nervousness, the baby not feeding properly, breathing problems and seizures. 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.

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