Warnings and precautions

Before starting treatment with Perazin 25 mg or Perazin 100 mg, you should 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 may cause hypotension.
Particular caution should be exercised when treating patients with perazine who have:

  • decreased white blood cell count (leukopenia) or other blood system disorders,
  • heart muscle damage in the past,
  • severe hypotension, sudden drop in blood pressure when changing from a lying to a standing position (orthostatic hypotension),
  • seizures in the past,
  • Parkinson's disease,
  • glaucoma with a narrow angle of filtration,
  • urination disorders, narrowing of the pylorus, prostate enlargement,
  • excessive motor activity associated with involuntary movements or decreased motor activity, stiffness, and muscle tremors (extrapyramidal 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 disease and chronic liver diseases,
  • narrowing of the pylorus,
  • hyperthyroidism,
  • adrenal chromaffin tumor,
  • disorders of new blood cell formation (hematopoiesis),
  • acute anemia,
  • breast tumors.

During treatment with perazine, it is necessary:

  • to constantly monitor blood glucose levels in patients with diabetes,
  • to monitor cardiovascular function: control of blood pressure 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 recommended in patients with heart diseases and defects,
  • to perform liver function tests (blood laboratory tests) at the beginning of treatment and then after 6 months.

In case of suspected malignant neuroleptic syndrome, it is recommended to immediately discontinue the medicine and seek medical help as soon as possible. Malignant neuroleptic syndrome, which occurs 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, after taking the medicine, the following occur:

  • changes in blood count (decrease in leukocytes, decrease in platelets),
  • nosebleeds,
  • disorders of consciousness, accompanied by illusions, visual, auditory, tactile, and other hallucinations (delirium),
  • depression,
  • skin changes of an allergic nature or irritation,
  • increased liver enzyme activity and jaundice.

In case of significant decrease in white blood cell count, as well as changes in 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 insufficient 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 25 mg or Perazin 100 mg and other medicines

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

  • levodopa causes mutual cancellation of their effects,
  • cimetidine causes an increase in perazine availability 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 effectiveness of antipsychotic treatment,
  • ethanol, sleeping pills, and sedatives increase sedative effects and the risk of respiratory complications (respiratory paralysis),
  • antiepileptic drugs (e.g., phenytoin, carbamazepine) reduce the effectiveness of perazine's antipsychotic and anticonvulsant effects,
  • oral anticoagulants weaken their anticoagulant effect,
  • MAO inhibitors and oral contraceptives result in a weakening of perazine's sedative effect and an increase in its side effects,
  • antidiabetic drugs reduce their effectiveness,
  • narcotic analgesics and other analgesic and antipyretic agents increase their analgesic and sedative effects,
  • tricyclic antidepressants (TCA, e.g., imipramine, amitriptyline) cause weaker effects of the medicines (mutual inhibition of medicine uptake by tissues),
  • selective serotonin reuptake inhibitors (SSRI, e.g., fluoxetine, fluvoxamine, sertraline) cause mutual inhibition of medicine uptake by tissues and a significant increase in perazine levels 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 blood count changes.

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

Taking Perazin 25 mg and Perazin 100 mg with alcohol

During treatment with perazine, you should not consume products containing alcohol.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should 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 it is necessary to use perazine treatment, you should stop breastfeeding.

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.

Perazin 25 mg contains lactose

3. How to take Perazin 25 mg and Perazin 100 mg

This medicine should always be taken according to the doctor's or pharmacist's recommendations. If you have any doubts, you should consult your doctor or pharmacist.
The medicine is taken orally.
Initially, 50 to 100 mg is taken per day, and in the further course of treatment, the dose is gradually increased to 300 to 600 mg per day in divided doses. The maximum therapeutic dose is 800 mg per day in divided doses. The maintenance dose is 75 to 300 mg per day.
Treatment of outpatients should be started with the smallest effective doses, and then the dose can be increased until the desired response to treatment is achieved.
Sudden changes in dosage are not recommended, as this increases the risk of side effects.
The maximum antipsychotic effect is achieved after one to three weeks of treatment.

Patients with renal impairment

In renal impairment, there is no need to change the dosage of the medicine.

Patients with liver impairment

In patients with liver function disorders, it is recommended to reduce the doses of perazine. It is recommended to use half of the adult dose, and in severe liver failure, discontinue the medicine.

Patients in old age

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

Use in children and adolescents

There is insufficient 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.

Symptoms
Accidental or intentional overdose (ingestion of several or several dozen grams of perazine) usually manifests as difficulty speaking, clumsiness, visual disturbances, muscle tremors, confusion, cardiac arrest, and respiratory failure, as well as disorders of thermoregulation (ability to maintain a constant body temperature).
Procedure in case of overdose
In case of taking a significantly higher dose of the medicine than recommended, you should immediately consult a doctor or pharmacist.

Stopping treatment with Perazin 25 mg or Perazin 100 mg

Treatment of psychotic disorders is long-term. After achieving satisfactory improvement, it is not recommended to reduce the dose of the medicine too quickly. The doses should be reduced gradually over several to several dozen months.
