Anosmia treatment: what to expect

A clinician may examine the nose, review recent infections and medicines, and check whether the loss is complete or partial. Treatment is then matched to findings rather than using one remedy for every person.

Blocked airflow from allergic rhinitis, a common cold, or chronic sinusitis can prevent odour molecules from reaching the smell area high in the nose. Care may focus on reducing inflammation or treating the underlying nasal problem. Smell loss can also follow COVID-19 or persist with Long COVID even when the nose feels clear.

Smell training involves regularly and attentively smelling a small set of familiar scents. It aims to exercise recognition rather than force an immediate result. A clinician can explain a suitable routine and review progress.

Note when the change began, whether it followed congestion, infection, injury, or a new medicine, and whether taste seems different. Do not stop prescribed medicine without clinical advice. Avoid putting unapproved drops, oils, or powders inside the nose because they may irritate delicate tissue.

Check smoke and gas alarms, follow expiry dates rather than relying on smell, label opened food, and ask someone else to check suspicious odours. These precautions matter because anosmia can hide smoke, gas leaks, and spoiled food.

Arrange a medical assessment if smell does not return after congestion settles, keeps worsening, affects eating, or has no clear explanation. Seek urgent care when sudden smell loss follows a head injury or occurs with facial weakness, trouble speaking, confusion, severe headache, new vision problems, or weakness in an arm or leg.

Ask whether nasal examination or further assessment is appropriate, whether any current medicine could affect smell, how to perform smell training safely, and which changes should prompt an earlier review.
