Could Hederasal have caused an allergy in a child?

The symptoms you mentioned may indicate an allergy, but they may also be the expected effect of the drug. Hederasal is an expectorant syrup – the ivy extract contained in it irritates the gastric mucosa, stimulating cough, which is designed to facilitate expectoration of secretions. An increase in nasal discharge may be one of the symptoms of an ongoing viral infection. The manufacturer informs about the possibility of allergy symptoms after taking Hederasal, however, mainly cases of rash, hives and shortness of breath have been registered. If you think that the drug caused undesirable effects in your child, it is worth reporting the side effect to the appropriate institutions.

Due to the lack of detailed information about the age and health of the child, let me not propose specific products, instead I enclose a link to the product group: https://www.gdziepolek.pl/kategorie/kaszel-u-dziecka I encourage you to read the article: https://www.gdziepolek.pl/artykuly/kaszel-suchy-i-mokry-jak-go-leczyc
