Contents of the pack and other information:
Dulotex 120 mg contains the active substance duloxetine. Dulotex 120 mg increases the levels of serotonin and noradrenaline in the nervous system.
Duloxetine is used in adults to treat:
Duloxetine usually starts to work in most people with depression or anxiety within 2 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 feel better after this time. Your doctor may continue to give you Dulotex 120 mg when you are feeling better to prevent your depression or anxiety from returning.
Do not take Dulotex 120 mg:
This medicine may not be suitable for you due to the following reasons.
Consult your doctor before taking this medicine if:
This medicine may cause a feeling of restlessness or an inability to sit or stand still. If this happens, you should tell your doctor.
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, overactive reflexes, diarrhea, coma, nausea, vomiting, as you may be suffering from a condition called serotonin syndrome.
In its most severe form, serotonin syndrome can resemble a condition called 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).
Some medicines of the same group as Dulotex 120 mg (called SSRIs/SNRIs) may cause sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.
If you are depressed and/or have an anxiety disorder, you may sometimes have thoughts of harming or killing yourself. These thoughts may be increased when you first start taking antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.
You are more likely to have these thoughts if:
Contact your doctor or go to the hospital immediately if you experience any thoughts of self-harm or suicide.
It may be helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behavior.

In addition, you should know that patients under 18 have an increased risk of side effects such as suicide attempt, suicidal thoughts, and hostility (predominantly aggression, oppositional behavior, and anger) when they take this class of medicines. Despite this, your doctor may prescribe this medicine to patients under 18 because they decide that it is in the patient's best interest. If your doctor has prescribed this medicine to a patient under 18 and you want to discuss this, please contact your doctor again. You should inform your doctor if any of the above symptoms occur or worsen in patients under 18 taking this medicine.

Examples of MAOIs include moclobemide (an antidepressant) and linezolid (an antibiotic).

These medicines increase the risk of side effects; if you notice any unusual symptoms when using any of these medicines with this medicine, you should tell your doctor.

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 how to reduce your dose over at least 2 weeks before stopping treatment.

(especially in the head), sleep disturbances (vivid dreams, nightmares, inability to sleep), fatigue, drowsiness, restlessness or agitation, anxiety, nausea or vomiting, tremor, headache, muscle pain, irritability, diarrhea, and excessive sweating or dizziness.
