Warnings and precautions

Before starting treatment with Perazin 50 mg and Perazin 200 mg, discuss it with your doctor, pharmacist, or nurse.
In case of liver function disorders, the dose should be reduced accordingly (see point 3).
After taking the maximum doses, severe liver damage may occur.
Caution should be exercised in patients with renal failure, as phenothiazine derivatives can cause hypotension.
Particular caution should be exercised when treating patients with perazine who have been diagnosed with:

• decreased white blood cell count (leukopenia) or other blood system disorders,
• heart muscle damage in the medical history,
• severe hypotension, sudden drop in blood pressure occurring as a result of rapid transition from a lying to a standing position (orthostatic hypotension),
• seizures in the medical history,
• Parkinson's disease,
• glaucoma with a narrow angle of filtration,
• urination disorders, narrowing of the pylorus, prostate hypertrophy,
• excessive motor activity associated with involuntary movements or decreased motor activity, stiffness, and muscle tremors (extrapyramidal system disorders),
• motor disorders, manifested by, among others, choreiform movements (dyskinesia),
• myasthenia gravis (a disease characterized by rapid fatigue and weakness of skeletal muscles),
• active peptic ulcer and chronic liver diseases,
• narrowing of the pylorus,
• hyperthyroidism,
• chromaffin tumor of the adrenal gland,
• disorders of new blood cell formation (hemopoiesis),
• acute anemia,
• breast tumors.

During treatment with perazine, it is necessary:

• constant monitoring of blood glucose levels in patients with diabetes,
• monitoring of the circulatory system: blood pressure control and observation of possible arrhythmias; for this purpose, frequent blood pressure measurements and ECG tests should be performed; this is especially important in elderly patients; ECG monitoring is necessary in patients with heart diseases and defects,
• performing liver function tests (blood laboratory tests) at the beginning of treatment and then after 6 months.

You should stop taking the medicine immediately and contact your doctor as soon as possiblein case of suspected malignant neuroleptic syndrome.
2/7
Malignant neuroleptic syndrome, occurring in individual cases, is characterized by, among other things, an increase in body temperature to 40°C and muscle stiffness.
It is recommended to reduce the dose or discontinue the medicine and immediately perform blood tests if the following occur after taking the medicine:

• changes in the blood picture (decrease in the number of leukocytes, decrease in the number of platelets),
• nosebleeds,
• disorders of consciousness, accompanied by illusions, visual, auditory, tactile, and other hallucinations (delirium),
• depression,
• skin changes of the type of urticaria or irritation,
• increased liver enzyme activity and jaundice.

In case of significant decrease in the number of leukocytes, as well as changes in the peripheral blood smear, the doctor may decide to discontinue perazine treatment and use another medicine. During long-term treatment with perazine, blood tests should be performed every 6 months.
In case of motor disorders (early dyskinesia or parkinsonian syndrome) such as choreiform movements, involuntary movements, excessive motor activity, or decreased motor activity, stiffness, and muscle tremors, the doctor may recommend reducing the dose or introducing anti-parkinsonian treatment.
During treatment with perazine, cases of hypersensitivity to light have been reported. You should avoid intense sunlight and reduce sensitivity to light by using protective creams with UV filters.
The use of perazine may cause skin allergic reactions.

Children and adolescents

There is a lack of sufficient data to assess the safety of using the medicine in children and adolescents under 16 years of age, so perazine is intended only for the treatment of adults.

Elderly patients

Elderly patients should receive reduced doses of perazine. It is recommended to use half of the adult dose. Such dosing usually provides the desired therapeutic effect in elderly patients.

Perazin 50 mg and Perazin 200 mg with other medicines

Tell your doctor or pharmacist about all medicines you are taking now or have recently taken, as well as medicines you plan to take.
Taking perazine with:

• levodopa causes mutual cancellation of their effects,
• cimetidine causes an increase in the availability of perazine in the body,
• lithium carbonate increases the risk of nervous system damage and increased blood sugar levels,
• beta-adrenergic receptor blockers (lowering blood pressure) may lead to excessive lowering of blood pressure,
• anticholinergic agents (atropine, trihexyphenidyl) increase the risk of delirium, reduce the antipsychotic effect,
• sleeping pills and sedatives increase the sedative effect and the risk of respiratory complications (respiratory paralysis),
• antiepileptic drugs (e.g., phenytoin, carbamazepine) cause a decrease in the antipsychotic effect of perazine, weakening of the anticonvulsant effect,
• oral anticoagulants weaken the anticoagulant effect,

3/7

• MAO inhibitors and contraceptives result in a weakening of the sedative effect of perazine and an increase in the occurring side effects,
• antidiabetic drugs cause a decrease in their effect,
• narcotic analgesics and other painkillers and antipyretics increase their analgesic and sedative effects,
• tricyclic antidepressants (e.g., imipramine, amitriptyline) cause a weaker effect of the medicines (there is a mutual inhibition of the uptake of medicines by tissues),
• selective serotonin reuptake inhibitors (SSRIs, e.g., fluoxetine, fluvoxamine, sertraline) cause mutual inhibition of the uptake of medicines by tissues and a significant increase in the concentration of perazine in the blood,
• medicines that impair bone marrow function (myelotoxic), such as phenylbutazone, aminophenazone, chloramphenicol, result in an increased risk of bone marrow disorders and changes in the blood picture.

During perazine therapy, false pregnancy test results have been observed.

Using Perazin 50 mg and Perazin 200 mg with alcohol

During treatment with perazine, you should not consume products containing alcohol due to the risk of increased effect and respiratory complications.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
Perazine passes through the placental barrier, so its use in pregnant women is contraindicated.
Perazine passes into breast milk. If perazine treatment is necessary, breastfeeding should be discontinued.

Driving and using machines

The medicine may cause significant impairment of psychophysical fitness. During treatment with perazine, you should not drive vehicles or operate machines.
