Nasal sponge steroid shows promise for long COVID smell loss

NCT ID NCT05970731

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a steroid (beclomethasone) placed directly in the nose using a tiny sponge could help people who lost their sense of smell after COVID-19. Sixteen adults with smell loss lasting over 3 months received either the steroid or a placebo sponge twice, two weeks apart. The main goal was to see if the treatment led to a meaningful improvement on a smell test.

What this could lead to
If it works, this could point toward a treatment for smell loss after COVID-19.
What could go wrong
This is a very small early-phase trial with only 16 people, so results may not apply widely. The treatment is also short-term and may not restore smell for everyone.
