Persistent olfactory dysfunction is a recognised manifestation of long COVID. This protocol addresses Post COVID-19 condition in patients who continue to experience smell disturbance beyond the acute phase of infection.
Long COVID with olfactory dysfunction. Olfactory training is recommended for patients in this setting as a supported first-line intervention (evidence grade A, level I).
In addition to olfactory training, a topical nasal corticosteroid approach may be considered for eligible patients to address persistent smell impairment. The complete protocol — including full eligibility criteria, sequencing, contraindication checks, and clinical decision points — is available via the link below.
