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

Duloxetine TecniGen 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, or stabbing pain, or like an electric shock. There may be loss of sensation in the affected area, or it may occur that when the area is touched or exposed to heat, cold, or pressure, pain is produced)

Duloxetine starts to work in most people with depression or anxiety within two 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 notice any improvement 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 a few 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 you take Duloxetine TecniGen

Do not take Duloxetine 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 disease
• if you are taking or have taken in the last 14 days another medicine known as a monoamine oxidase inhibitor (MAOI) (see "Using Duloxetine TecniGen 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 "Using Duloxetine TecniGen 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 using other medicines to treat depression (see "Using Duloxetine TecniGen 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 had mania
• you have bipolar disorder
• you have eye problems, such as some types of glaucoma (increased eye pressure)
• you have had bleeding problems (a tendency to develop bruises)
• you are at risk of having low sodium levels (for example, 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 "Using Duloxetine TecniGen with other medicines")

Duloxetine 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 disorderIf you are depressed and/or have an anxiety disorder, you may sometimes have thoughts of self-harm or suicide. These thoughts may increase 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 had previous thoughts of self-harm or suicide
• you are a young adult. There is information from clinical trials that has shown an increased risk of suicidal behavior in adults under 25 years who are being treated with antidepressants for a psychiatric disorder.

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

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

It may be helpful if you 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 notice that your depression or anxiety is getting worse, or if they are worried about changes in your behavior.

Children and adolescents

Duloxetine is not normally 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 attempted suicide, suicidal thoughts, and hostility (mainly aggression, oppositional behavior, and anger). Despite this, your doctor may prescribe duloxetine to patients under 18 years because they decide that it may 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 appear or worsen in patients under 18 years who are taking duloxetine. Additionally, in this age group, the long-term safety effects of duloxetine related to growth, maturation, and cognitive and behavioral development 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, 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 heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).

Using Duloxetine TecniGen with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

The main component of Duloxetine 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 talking to your doctor.

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 in 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 with many prescription medicines, including duloxetine, can cause serious side effects, even life-threatening ones. 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, 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 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 TecniGen with food, drinks, and alcohol

Duloxetine can be taken with or without food. You should be cautious if you drink 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 have a baby, ask your doctor or pharmacist for advice before taking this medicine.

• Tell your doctor if you become pregnant or are planning to become pregnant while being treated with 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 more rapidly and turn blue. These symptoms usually start during the first 24 hours after birth. 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 born. These symptoms usually start at birth or in the first few days after birth. These symptoms may include weak muscles, trembling, restlessness, difficulty feeding, breathing problems, and seizures. If your baby has any of these symptoms when born, or if you are concerned about your baby's health, contact your doctor or midwife, who will be able to advise you.

• Tell your doctor if you are breastfeeding. It is not recommended to use duloxetine during breastfeeding. 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 operate tools or machines until you know how the treatment with duloxetine affects you.

Duloxetine TecniGen contains sucrose

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

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 per 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 you do not treat it, your condition may not get better and may become more serious and more difficult to treat.

If you stop taking Duloxetine TecniGen

DO NOT stop taking your capsules without the advice of your doctor, even if you feel better.If your doctor thinks you do not need to take duloxetine anymore, they will tell you to reduce your dose over at least 2 weeks before stopping treatment.
