Acute post-viral cough is a common symptom, usually mild-moderate and self-resolving. However, acute cough may be particularly annoying, affecting sleep, and quality of life, also of the family. Thus, treatment is deemed necessary. Antitussive remedies may be pharmacological or non-pharmacological. Antitussive drugs are either central or peripheral. Central drugs are burdened with significant side effects and can cause abuse, especially in adolescents. Levodropropyzine, on the other hand, is an effective peripheral drug, as demonstrated by two meta-analyses, and has an optimal safety profile. Non-pharmacological remedies tend to be safe, but few substances have a documented degree of efficacy. Therefore, when managing children and adolescents with a post-viral cough, the practical approach may be based on levodropropizine use, which is preferable when the cough is particularly persistent and disturbs sleep.
