In comparison with often applied aminazine Promazinum is transferred better and less often causes side effects.

In an initiation of treatment can arise: dizziness, drowsiness, accommodation disturbances (an illegibility of visual perception), frustration of a dream, dryness in a mouth, anorexia, a gastralgia, nausea, vomiting, a lock, tachycardia, moderately expressed orthostatic hypotension, a nose congestion, difficulty of an urination.

The following side effects are in rare instances noted: allergic reactions, Quincke's disease, cholestatic jaundice, pigmental retinopathy, disturbance of thermal control (heatstroke), disturbances of a cordial rhythm, skin photosensitization, increase in body weight, galactorrhoea, decrease in a sexual potentiality, priapism, disturbances of a menstrual cycle, melanosis, agranulocytosis, leukopenia, and also phenomena of overdue reaction to external irritations, phenomena of mental indifference and other changes of mentality.

At long use extrapyramidal frustration (the akinetorigidny phenomena, vegetative disturbances, hyperkinesias, an akathisia, a tremor, dyskinesia), in some cases – spasms are possible. As proofreaders of these phenomena use protivoparkinsonichesky drugs. Help to stop to dyskinesia sodium caffeine (subcutaneously 2 ml of 20% of solution) and atropine (subcutaneously 1 ml of 0,1% of solution).

In extremely exceptional cases development of a malignant antipsychotic syndrome is possible.

Special instructions

During treatment it is necessary to control carefully the arterial pressure and pulse, to constantly investigate functions of kidneys and a liver, a picture of peripheral blood, to perform ophthalmologic inspections.

It is necessary to consider that the Propazine applied as an antiemetic can mask the vomiting caused by overdose by other medicines.

Due to the risk of development of a photosensitization during treatment it is not necessary to be exposed to ultra-violet radiation.

During treatment it is forbidden to take alcoholic beverages, to manage motor transport and to carry out potentially dangerous types of works requiring high attention and speed of reactions.

Medicinal interaction

Possible reactions of interaction in case of simultaneous use of Propazine with other medicines:

• Other substances exerting the oppressing impact on the central nervous system (alcohol and etanolsoderzhashchy drugs, narcotic analgetics, barbiturates, anesthetics, tranquilizers, etc.): the depression of the central nervous system and respiratory depression amplifies;
• Other drugs causing extrapyramidal reactions: frequency and weight of extrapyramidal disturbances increases;
• Epinephrinum (adrenaline): the perversion of effect of Epinephrinum is possible that can lead to falling of arterial pressure (such combination should be avoided);
• Tricyclic antidepressants, monoamine oxidase inhibitors, Maprotilinum: the risk of development of a malignant antipsychotic syndrome increases;
• Anticonvulsant drugs: the convulsive threshold goes down;
• Drugs for treatment of a hyperthyroidism: the risk of development of an agranulocytosis increases;
• Hypotensive drugs: there is a probability of development of the expressed orthostatic hypotension;
• Ephedrine: its vasoconstrictive action is weakened;
• Apomorphinum: its emetic effect decreases, the oppressing action on the central nervous system amplifies;
• The means reducing appetite (except for a fenfluramin): their efficiency decreases;
• Amphetamine, clonidine, гуанетидин: their action can be suppressed;
• Bromocriptinum: increase in concentration in a blood plasma of prolactin and decrease in its action is possible;
• Levodopa: its protivoparkinsonichesky action decreases;
• Protivoparkinsonichesky means, antacids, lithium drugs: absorption of Promazinum is broken;
