Interaction

MAO inhibitors may increase and prolong the anticholinergic effect of chloroniramine. Increases the effect of drugs for general anesthesia sedative tranquilizers analgesics (including opioid) local anesthetics atropine symnagolytics barbiturates M-cholinoblockers. Simultaneous use with ethanol is not recommended (risk of severe CNS depression).

Tricyclic antidepressants increase m-cholinoblocking and depressant effect on CNS. Antihistamines may interfere with the manifestation of reactions during skin allergy testing, so a few days before the planned test, the drugs of this type should be discontinued.

Chloropyramine may mask the signs of complications likely during treatment with ototoxic drugs in case of their simultaneous use.

Special Instructions

Chloropyramine may mask early signs of ototoxicity when combined with ototoxic drugs. Liver and kidney disease may require modification (reduction) of the drug dose. Taking the drug at night may increase the symptoms of reflux esophagitis. Simultaneous use of ethanol (alcoholic beverages) is unacceptable. Prolonged use of antihistamines may lead to disorders of hematopoiesis (leukopenia agranulocytosis thrombocytopenia hemolytic anemia). If during long-term treatment unexplained increase in body temperature is observed laryngitis pallor of skin jaundice formation of mouth ulcers appearance of hematomas unusual and prolonged bleeding should be tested to determine number of blood cells. If the test results indicate a change in blood count, the drug should be discontinued.

Effects on the ability to operate vehicles and machinery:

Chloropyramine especially in the initial period of treatment may cause drowsiness, fatigue and dizziness. Therefore, in the initial period, the duration of which is determined individually, it is prohibited to drive vehicles or perform work associated with an increased risk of accidents. Thereafter the degree of restriction to drive vehicles and work with mechanisms should be determined for each patient individually by the physician.
