What else does the instruction manual for Thiodazine tell us?
Dosage of drug
The dosage and time of taking this drug must be selected individually, depending on the type of disease and the severity of its symptoms. It is recommended to start therapy with doses that are at the lower boundary of the designated range. Further, in the course of treatment, the dosage is gradually increased to the maximum effective rate. After reaching the maximum therapeutic effect, the dosage is gradually reduced to maintenance therapy. The daily dose is usually divided into two to four doses.
So, we will consider how to take "Thiodazine" for schizophrenia and other psychoses:

The instructions for use with "Thiodazine" indicate that therapy of this category of patients should be started with especially small dosages, increasing them very slowly.
In patients with schizophrenia who are in hospital treatment, a noticeable positive effect is achieved, as a rule, after three weeks from the start of therapy. In patients with chronic psychosis, it may take from six weeks to six months to achieve the maximum effect. But in patients with acute psychosis, improvement can be noted after two days.
In accordance with the instructions for use with the drug "Thiodazine", in the case of prolonged treatment, it is recommended to reduce its dosage gradually, over a couple of weeks. Sudden abandonment of the drug in patients who received it for a long time or in high dosage can lead in some cases to side effects in the form of nausea, vomiting, tremor, dizziness, anxiety, agitation and insomnia. Transient dyskinesias are not excluded. Such reactions can create the erroneous impression that a patient has depressed or psychotic conditions.
Side effects
Adverse reactions with the use of the drug, as with other drugs based on phenothiazine, are directly dependent on the dosage and, as a rule, are caused by the pronounced pharmacological effect of the drug. If this medicine is used within the recommended dose range, adverse reactions in most situations are mild and have a transient character. Severe adverse reactions are usually noted due to the use of high dosages.
According to the instructions and reviews for “Thiodazine”, the nervous system can react with sedation and drowsiness, dizziness along with impaired consciousness, psychomotor agitation, hallucinations, increased irritability and headache are also possible. In addition, convulsions are quite likely, and, in addition, extrapyramidal symptoms in the form of tremor, muscle rigidity, akathisia, dyskinesia and dystonia. The appearance of depression, insomnia, malignant antipsychotic syndrome and the like is not ruled out.
The autonomic nervous system can respond to this medication with the appearance of anticholinergic effects in the form of dry mouth, blurred vision, paresis of accommodation and nasal congestion. This is confirmed by the instructions for use with "Thiodazine" and reviews. In addition, nausea, vomiting, diarrhea, constipation, loss of appetite, retention or urinary incontinence, pallor of the skin and tremor are possible. Very rarely paralytic bowel obstruction can be observed.
The work of the heart and blood vessels may be accompanied by orthostatic hypotension, changes in the electrocardiogram, tachycardia and arrhythmia. It is extremely rare that ventricular flutter and flicker, and, in addition, sudden death.
With long-term use of Thiodazine, the endocrine system can respond with hyperprolactinemia, galactorrhea, amenorrhea, menstrual irregularities, changes in body weight, erectile dysfunction and ejaculation. In addition, priapism is possible along with engorgement of the mammary glands, gynecomastia and peripheral edema.
In addition, peripheral blood changes in the form of leukopenia, agranulocytosis, thrombocytopenia, anemia and leukocytosis can be observed. Liver function may be accompanied by abnormal enzyme activity and hepatitis. The skin can react with dermatitis, an allergic rash, urticaria, increased photosensitivity and angioedema. Among other adverse reactions, edema in the area of ​​the parotid gland is possible along with hyperthermia and respiratory depression.
Such information is contained in the instructions for use with Thiodazine. Analogs should be selected by the doctor if this drug is not suitable for the patient.
Overdose
With long-term treatment with Thiodazine, there were reports of cases of pigmented retinopathy, which developed in patients who received the drug at a dosage exceeding the recommended maximum values, that is, more than 800 milligrams per day.
Against the background of an overdose, side effects and the development of an acute antipsychotic reaction are possible. In particular, it should alert the fever, which may be one of the symptoms of the development of malignant antipsychotic syndrome. In more severe cases of overdose, various forms of impaired consciousness and even coma are possible. Overdose care measures should be as follows:
- Discontinuation of treatment with thiodazine and any similar antipsychotic medications (ie antipsychotics).
- Stopping the use of correctors, that is, central anticholinergic blockers.
- High doses of activated carbon should be prescribed along with gastric lavage.
- In case of seizures, the patient requires intravenous administration of Diazepam with glucose solution, nootropic drugs and vitamins B and C.
- A thorough monitoring of the functions of the cardiac, respiratory, vascular and nervous systems.
- Conducting symptomatic therapy.
If the patient has seizures, the use of barbiturates should be avoided, since they can enhance respiratory depression, which will be caused by the phenothiazine derivative.
Drug interaction
Medications like Cimetidine, Fluoxetine, Paroxetine, and Moclobemide can enhance and lengthen the effects of Thiodazine. The simultaneous administration of tricyclic antidepressants with phenothiazine derivatives can lead to an increase in the plasma concentration of all these medical devices, which can cause arrhythmia.
The substance thioridazine, like other phenothiazines, can lower the threshold for convulsive readiness. In the case of the simultaneous use of anticonvulsants with thioridazine, an increase or decrease in the concentration of phenytoin in the serum is likely, and therefore, it may be necessary to adjust its dosage. As part of the combined use of Thiodazine and Carbamazepine, the concentration of these drugs in serum does not change.

With the simultaneous use of thioridazine with antiparkinsonian drugs, for example, with Levodopa, the effects of both medicines can be weakened. Due to its adrenergic blocking property, thioridazine can weaken the pressor effect of vasoconstrictor drugs, such as: Epinephrine, Dopamine, Ephedrine and Phenylephrine. Against the background of the simultaneous use of "Quinidine" and "Thiodazine", the inhibitory effect of the first medicine on the myocardium is possible.
Phenothiazines, including Thiodazine, can cause changes in the electrocardiogram, such as lengthening the QT interval. The simultaneous use of "Thiodazine" with thiazide diuretics can lead to the development of severe arterial hypotension. In addition, hypokalemia caused by diuretics can enhance the cardiotoxic effect of “Thiodazine”.
The substance thioridazine has an effect on carbohydrate metabolism, and therefore, its use may impair the patient's tolerance to glucose, which was achieved during therapy with hypoglycemic agents. Antacids and antidiarrheal medicines can reduce the absorption of thioridazine from the digestive system. This is confirmed by the instructions for use with the tablets “Thiodazine”.
Special instructions for use
Against the background of treatment, alcohol is strictly prohibited, and in addition, driving vehicles. The drug has a direct effect on the nervous system, and therefore, it is better not to attend work and public places during treatment.
