mania: the patient may be very excited, happy, agitated, enthusiastic or overly active, may also have an inappropriate assessment of the situation, including aggressive or destructive behavior;
schizophrenia: the patient may hear or feel things that do not actually exist, has beliefs that contradict reality or is extremely suspicious, frightened, disoriented, feels guilty, anxious or depressed.
The doctor may recommend continued use of Kwetaplex, even if the patient feels better.

2. Important information before taking Kwetaplex

• erythromycin or clarithromycin (used to treat infections);

Do not take Kwetaplex if any of the above situations apply to the patient. In case of doubts, before starting treatment with Kwetaplex, consult a doctor or pharmacist.

Warnings and precautions

Before starting treatment with Kwetaplex, discuss it with your doctor, pharmacist or nurse

• if the patient or their family members have or have had heart diseases, such as arrhythmias, heart muscle weakness or myocarditis, or if the patient is taking medicines that may cause changes in heart rhythm;
• if the patient has low blood pressure;
• if the patient has had a stroke, especially if they are elderly;
• if the patient has liver problems;
• if the patient has had seizures (convulsions);
• if the patient has diabetes or is at risk of diabetes. If so, the doctor may check the patient's blood sugar levels while taking Kwetaplex;
• if the patient has had a low white blood cell count in the past (which may, but does not have to be, caused by other medicines);
• if the patient is an elderly person with dementia (reduced cognitive function). Such a person should not take Kwetaplex, as medicines in this group may increase the risk of stroke, and sometimes even death, in such patients,
• if the patient is an elderly person with Parkinson's disease/parkinsonism,
• if the patient or their family members have had blood clots, as such medicines may cause blood clots,
• if the patient has or has had conditions during which breathing stops for short periods during normal night sleep (so-called sleep apnea) and takes medicines that slow down normal brain activity (so-called depressants);
• if the patient has or has had a problem with complete emptying of the bladder (urinary retention), has an enlarged prostate, intestinal obstruction or increased intraocular pressure. These symptoms are sometimes caused by medicines taken to treat certain diseases that affect the functioning of nerve cells (so-called anticholinergic products).
• if the patient has had problems with alcohol or drug use.

You should immediately inform your doctor if you experience symptoms such as:

• a syndrome of symptoms: fever, muscle stiffness, sweating or decreased level of consciousness (a disease called malignant neuroleptic syndrome). Immediate medical attention may be necessary;
• uncontrolled movements, mainly of the face and tongue;
• dizziness or severe drowsiness. This may increase the risk of accidental injuries (falls) in elderly patients;
• seizures (convulsions);
• prolonged painful erection (priapism);
• rapid and irregular heartbeat, even at rest, palpitations, difficulty breathing, chest pain or unexplained fatigue. The doctor will need to examine the heart and, if necessary, immediately refer the patient to a cardiologist.

These symptoms may be caused by the use of antipsychotic medicines.
You should inform your doctor as soon as possible if you experience symptoms such as:
fever, flu-like symptoms, sore throat or other infections that may be a sign of a low white blood cell count. This may require discontinuation of Kwetaplex therapy and/or the use of appropriate treatment;
Page 2 of 10
constipation with persistent abdominal pain or constipation that does not improve with treatment. This may lead to serious bowel obstruction;
suicidal thoughts or worsening depression.
If the patient is depressed, they may experience thoughts of harming themselves or committing suicide. These thoughts may be particularly severe at the beginning of treatment, as the effect of the medicines develops gradually, usually within about 2 weeks, and sometimes longer. These thoughts may also worsen after sudden discontinuation of treatment. These thoughts are more likely to occur in young adults. Clinical trials indicate an increased risk of suicidal thoughts and/or behaviors in young adults, under the age of 25, with depression.
If thoughts of self-harm or suicide occur, you should immediately contact your doctor or go to the hospital. It may be helpful to inform a relative or friend about your depression and ask them to read this leaflet. The patient may ask these people to inform them if they notice an increase in depressive symptoms or other changes in the patient's behavior.

Severe skin reactions

During the use of this medicine, very rare severe skin reactions (SCAR, English severe cutaneous adverse reactions) have been reported, which can be life-threatening or fatal. They usually occur as:

• Stevens-Johnson syndrome (English Stevens Johnson syndrome, SJS) widespread rash with blisters and peeling of the skin, especially in the mouth, nose, eyes and genital areas;
• toxic epidermal necrolysis (English toxic epidermal necrolysis, TEN), a more severe form causing widespread peeling of the skin;
• rash with eosinophilia and systemic symptoms (DRESS), includes flu-like symptoms with rash, fever, swelling of the glands and abnormal blood test results (including increased white blood cell count (eosinophilia) and liver enzymes).
