1. What is Pinexet and what is it used for

Pinexet contains the active substance quetiapine. It belongs to a group of antipsychotic medicines.
Pinexet is used to treat several diseases, such as:

• depressive episodes in bipolar disorder, when the patient feels sad, depressed, lacks energy, loses appetite, cannot sleep;
• mania, when the patient is very excited, agitated, overactive, or has impaired critical judgment, is aggressive or troublesome;
• schizophrenia, when the patient hears and sees unreal voices and images, takes non-existent things for real, is overly suspicious, anxious, confused, feels guilty, is tense, depressed.

The doctor may recommend taking Pinexet even when the patient's condition has already improved.

2. Important information before taking Pinexet

When not to take Pinexet

• azoles (used to treat fungal infections),
• erythromycin or clarithromycin (used to treat infections),
• nefazodone (used to treat depression).

If any of the above situations apply to the patient, they should not take Pinexet.
In case of doubts, consult a doctor or pharmacist before taking Pinexet.

Warnings and precautions

Before starting to take Pinexet, the patient should discuss it with their doctor or pharmacist if:

• the patient or someone in their family has or has had any heart problems, such as arrhythmias, heart muscle weakness, or myocarditis, or if the patient is taking or has taken any medicines that may affect heart function
• the patient has low blood pressure
• the patient has had a stroke, especially if the patient is elderly
• the patient has liver problems
• the patient has ever had a seizure (epilepsy)
• the patient has diabetes or is at risk of developing diabetes. In such cases, the doctor may check the patient's blood sugar levels during treatment with Pinexet.
• the patient has had a decreased white blood cell count in the past (which may have been caused by the action of other medicines)
• the patient is an elderly person with dementia (impairment of brain function). In such a case, Pinexet should not be taken, as medicines in the same class as Pinexet may increase the risk of stroke and sometimes the risk of death in such patients.
• the patient or their family members have had blood clots; the use of medicines like this one is associated with the formation of blood clots
• the patient has or has had short pauses in breathing during sleep (sleep apnea) and is taking medicines that slow down brain activity (antidepressants, sedatives)
• the patient has or has had problems with complete emptying of the bladder (urinary retention), enlarged prostate, intestinal obstruction, or increased eye pressure
• the patient has abused alcohol or drugs
• the patient has depression or other conditions that are treated with antidepressant medicines. Taking these medicines with Pinexet may lead to the development of serotonin syndrome, a life-threatening condition (see "Pinexet and other medicines").

The patient should immediately inform their doctor if they experience any of the following after taking Pinexet:

• combined: fever, muscle stiffness, excessive sweating, consciousness disorders (a condition called malignant neuroleptic syndrome); immediate treatment may be necessary
• involuntary movements, especially of the face or tongue
• dizziness or severe drowsiness; these changes may increase the risk of accidental injury (falls) in elderly patients
• seizures (epilepsy)
• rapid and irregular heartbeat, even at rest, palpitations, breathing difficulties, chest pain, or unexplained fatigue. The doctor will need to examine the heart and, if necessary, refer the patient to a cardiologist immediately
• prolonged painful erection (priapism).

All these symptoms may occur during treatment with medicines in this therapeutic class.

The patient should immediately inform their doctor if they experience:

• combined: fever, flu-like symptoms, sore throat, or any infections, as this may be a consequence of a very low white blood cell count in the blood, and it may be necessary to discontinue Pinexet and/or administer appropriate treatment
• constipation combined with persistent abdominal pain or persistent constipation despite treatment, as this may lead to a more serious bowel obstruction.

Suicidal thoughts or worsening depression

People with depression may sometimes have thoughts of self-harm or suicide. Such symptoms or behaviors may worsen during the initial phase of treatment, as all antidepressant medicines start to work after some time, usually after two weeks, sometimes later. These thoughts may worsen after sudden discontinuation of the medicine. Young adults are more likely to have such thoughts. Data from clinical trials indicate an increased risk of suicidal thoughts and/or suicidal behaviors in people under 25 years of age with depression.
If the patient has ever had suicidal thoughts or thoughts of self-harm, they should immediately contact their doctor or go to the hospital. It may be helpful to inform relatives or friends about the depression and ask them to read this leaflet.
It may also be helpful to ask these people to tell the patient if they notice any worsening of depressive symptoms or other worrying changes in behavior.

Weight gain

Patients taking Pinexet have been observed to gain weight. Therefore, the patient's weight should be checked regularly.

Children and adolescents

Pinexet is not intended for use in children and adolescents under 18 years of age.

Pinexet and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.

• certain medicines used to treat HIV,
• azoles (used to treat fungal infections),
• erythromycin or clarithromycin (used to treat infections),
• nefazodone (used to treat depression).

The patient should tell their doctor if they are taking:

• antiepileptic medicines (such as phenytoin or carbamazepine),
• antidepressant medicines. These medicines may interact with Pinexet and may cause symptoms such as involuntary, rhythmic muscle contractions, including eye movements, agitation, hallucinations, coma, excessive sweating, tremors, increased reflexes, muscle tension, body temperature above 38°C (serotonin syndrome). If such symptoms occur, the patient should consult their doctor.
• antihypertensive medicines,
• barbiturates (medicines used to treat sleep disorders),
• thioridazine or lithium salts (other antipsychotic medicines),
• medicines that affect heart rhythm, such as those that can disrupt electrolyte balance (decrease potassium and magnesium levels), such as diuretics (which increase urine production) or certain antibiotics (used to treat infections),
• medicines that can cause constipation,
• anticholinergic medicines.

Before stopping treatment with any medicine, the patient should tell their doctor.

Pinexet with food, drinks, and alcohol

• The patient should be careful with the amount of alcohol they consume. Taking Pinexet and alcohol at the same time may cause drowsiness.

tremors, muscle stiffness and/or weakness, drowsiness, agitation, breathing difficulties, and feeding difficulties. If the patient's child experiences any of these symptoms, they may need to contact their doctor.

Driving and using machines

Pinexet may cause drowsiness. The patient should not drive or operate machinery until they know how the medicine affects them.

Effect on urine tests for drug detection

Taking quetiapine may result in a positive test result for methadone or certain antidepressant medicines (tricyclic antidepressants) in the urine, even if the patient has not taken them. In such a case, more detailed tests should be performed using other methods to confirm the results.

Pinexet contains lactose and sodium

If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking Pinexet.
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means it is considered "sodium-free".
