• If you have any questions, consult your doctor or pharmacist.
• This medication has been prescribed to you alone and should not be given to others, even if they have the same symptoms as you, as it may harm them.

Contents of the package and additional information

Oxitril contains the active ingredient duloxetina. Oxitril increases the levels of serotonin and noradrenaline in the nervous system.

Oxitril is used in adults to treat:

• depression
• generalized anxiety disorder (chronic sensation 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 touching the area or exposing it to heat, cold, or pressure)

Oxitril 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 Oxitril 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 Oxitril if:

• You are allergic to duloxetine or any of the other components of this medication (listed in section 6)
• You have liver insufficiency
• You have severe kidney insufficiency
• You are taking or have taken in the last 14 days another medication known as monoamine oxidase inhibitor (MAOI) (see “Other medications and Oxitril”)
• You are taking fluvoxamine, which is usually used to treat depression, ciprofloxacin or enoxacin, which are used in the treatment of some infections
• You are taking other medications that contain duloxetine (see “Other medications and Oxitril”)

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

Warnings and precautions

Oxitril may not be suitable for you for the following reasons. Consult your doctor or pharmacist before starting to take Oxitril if:

• You are taking other medications to treat depression (see “Other medications and Oxitril”)
• You are taking St. John's Wort, a herbal treatment (Hypericum perforatum)
• You are taking buprenorphine or the combination buprenorphine/naloxone. The use of these medications with Oxitril may cause serotonin syndrome, a potentially life-threatening disease (see “Other medications and Oxitril”)
• You have any kidney disease
• You have had seizures (epileptic attacks)
• 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, especially if you are pregnant (see “Pregnancy and breastfeeding”)
• 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 medications that may cause liver damage
• You are taking other medications that contain duloxetine (see “Other medications and Oxitril”)

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

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

Thoughts of suicide and worsening of depression or anxiety disorder

If you are depressed and/or have anxiety disorders, you may occasionally have thoughts of self-harm or suicide. These thoughts may be increased at the beginning of treatment with antidepressants, as all these medications take time to take effect, usually two weeks but sometimes longer.

You are more likely to 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 behavior in adults under 25 years old who have a psychiatric disorder and are being treated with antidepressants.

Contact your doctor or go directly to the hospital as soon as 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 an anxiety disorder, 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 behavior.

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 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).

Children and adolescents

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

Other medications and Oxitril

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication, including those purchased without a prescription.

The main component of Oxitril, duloxetine, is used in other medications for other treatments:

• Diabetic neuropathic pain, depression, anxiety, and urinary incontinence.

You should avoid using more than one of these medications at the same time. Check with your doctor if you are already using other medications that contain duloxetine.

Your doctor will decide if you can take Oxitril with other medications.Do not start or stop using any medication, including those purchased without a prescription, without first consulting your doctor.

You should also tell your doctor if you are taking any of the following medications:

Monoamine oxidase inhibitors (MAOIs):You should not take Oxitril if you are taking, or have taken recently (in the last 14 days), another medication antidepressant known as monoamine oxidase inhibitor (MAOI). Examples of MAOIs include moclobemide (an antidepressant) and linezolid (an antibiotic). Taking an MAOI with many prescription medications, including Oxitril, may cause serious side effects, even life-threatening. You should wait at least 14 days after stopping treatment with an MAOI before taking Oxitril. Similarly, you should wait at least 5 days after stopping treatment with Oxitril before starting treatment with an MAOI.

Medications that cause drowsiness:This includes prescription medications such as benzodiazepines, powerful analgesics, antipsychotics, phenobarbital, and antihistamines.

Medications 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, amitriptyline), petidina, St. John's Wort, and MAOIs (such as moclobemide and linezolid). These medications increase the risk of side effects; if you observe any unusual symptoms when using any of these medications with Oxitril, tell your doctor.

Buprenorphine/opioids:Oxitril will be administered with caution when administered concomitantly with buprenorphine or the combination buprenorphine/naloxone, as it increases the risk of serotonin syndrome, a potentially life-threatening disease (see section 4.4).

Oral anticoagulants or antiplatelet agents:Medications that thin the blood or prevent the formation of blood clots. These medications may increase the risk of bleeding.

Taking Oxitril with food, drinks, and alcohol

Oxitril can be taken with or without food. You should be careful if you take alcohol while taking Oxitril.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medication.

• Inform your doctor if you become pregnant or if you are trying to become pregnant while taking Oxitril. You should only use Oxitril after discussing the potential benefits and any potential risks to the fetus with your doctor.
• Make sure your midwife and/or doctor know that you are taking Oxitril. Other similar medications (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 Oxitril when you are approaching the end of your pregnancy, your baby may have some symptoms when born. These usually start at birth or within the first few days after your baby's birth. These symptoms may include weak muscles, tremors, nervousness, that the baby does not feed properly, 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 can advise you.
• If you take Oxitril when you are approaching the end of your pregnancy, there is a higher risk of excessive vaginal bleeding shortly after birth, especially if you have had bleeding problems. Your doctor or midwife should know that you are taking duloxetine so they can advise you.
• The available data on the use of Oxitril during the first three months of pregnancy do not show a general increase in the risk of birth defects in the child. If you take Oxitril during the second half of pregnancy, there may be a higher risk of the baby being born prematurely (6 additional premature births per 100 women taking Oxitril in the second half of pregnancy), especially between weeks 35 and 36 of pregnancy.
• Inform your doctor if you are breastfeeding. Oxitril is not recommended during breastfeeding. Ask your doctor or pharmacist for advice.

Driving and using machines

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

Oxitril contains saccharose and invert sugar

Oxitril contains compressible sugar that includes saccharose and invert sugar (glucose and fructose). If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

Follow exactly the administration instructions of this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Oxitril should be taken orally. Swallow the tablet whole with water.

For depression and diabetic neuropathic pain:

The recommended dose of Oxitril 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 Oxitril 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 can be adjusted up to 120 mg per day depending on your response to Oxitril.

To avoid forgetting to take Oxitril, it may be helpful to take it at the same time every day.

Discuss with your doctor for how long you should take Oxitril. Do not stop taking Oxitril, or change your dose without consulting your doctor. It is essential to treat your condition properly to help you improve. If you do not treat it, your condition may not disappear and may become more severe and harder to treat.

If you take more Oxitril than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone: 91 562 04 20, indicating the name of the medication and the amount ingested.

Among the symptoms produced by an overdose are drowsiness, coma, serotonin syndrome (a rare reaction that can cause a feeling of intense happiness, drowsiness, clumsiness, restlessness, feeling drunk, fever, sweating, or muscle rigidity), seizures, vomiting, and high heart rate.

If you forget to take Oxitril

If you forget to take a dose, take it as soon as you remember. However, if it is time for the next dose, skip the missed dose and take a single dose as you normally do. Do not take a double dose to compensate for the missed doses. Do not take more Oxitril than prescribed for you in a day.

If you interrupt treatment with Oxitril

Do not stop taking your tablets without your doctor's advice, even if you feel better. If your doctor thinks you no longer need to take Oxitril, they will instruct you to reduce your dose for at least 2 weeks before stopping treatment.

Some patients who have stopped treatment with duloxetine hydrochloride have presented symptoms such as:

• Dizziness, feeling of pins and needles or electric shock (especially in the head), sleep disturbances (intense dreams, nightmares, inability to sleep), fatigue, drowsiness, feeling of restlessness or agitation, feeling of anxiety, nausea or vomiting, tremors, headaches, muscle pain, feeling of irritability, diarrhea, and excessive sweating or vertigo.
