Parlazine, 10 mg 10 pcs.

Parlazine is an anti-allergic agent.

Pharmacodynamics

Cetirizine is a carboxylated metabolite of hydroxyzine, belongs to the class of antihistamine drugs of piperazine derivatives. The action of cetirizine and its antiallergic effects are based on selective blockade of peripheral histamine H₁ receptors. By this mechanism, cetirizine suppresses early histamine-mediated allergic reactions, reduces the migration of inflammatory cells and the release of mediators associated with later allergic reactions. Cetirizine has only minor anticholinergic and antiserotoninergic effects.

Children aged 1-2 years: 2.5 mg (5 drops) 2 times a day.

Special Instructions

In case of hypersensitivity reactions, the drug should be stopped immediately.
Kidney disease. Due to decreased excretion rate of cetirizine it may accumulate in patients with impaired renal function; in this case the frequency and severity of anticholinergic side effects or effects on the CNS may increase, even in case of taking the usual dose for adults. Therefore, in such cases it is recommended to reduce the dose.
Elderly patients are particularly sensitive to the anticholinergic effects of antihistamines (e.g., dry mouth, urinary retention). If these side effects are observed for a long time, and if their intensity increases, the drug should be discontinued. Although cetirizine is less likely to cause anticholinergic side effects or severe CNS side effects, it can accumulate (age-related decreased renal function is more likely in elderly patients) and cause anticholinergic side effects or CNS side effects even when administered at the usual dose for adults.
Coated tablets contain lactose, therefore this drug should not be administered to patients with lactose intolerance and/or glucose-galactose malabsorption syndrome.
Skin tests:
the use of Parlazine should be stopped at least 3 days before the allergic skin test in order to avoid false-negative results.

Contraindications

With caution: the drug is indicated in moderate to severe chronic renal failure (dosage regimen adjustment is required) and in elderly patients (dosage regimen adjustment is required).

Overdose

Symptoms (at a single dose of 50 mg): confusion, dizziness, headache, increased fatigue, weakness, malaise, sedation, drowsiness, stupor, mydriasis, pruritus, tremor, diarrhea, urinary retention.

Treatment: gastric lavage, provocation of vomiting; intake of activated charcoal, symptomatic and supportive therapy. There is no specific antidote. Hemodialysis is ineffective.
