Survey of Fifth Sense Members with Post-Viral Olfactory Loss

This survey is designed to capture essential background information for a trial proposal that will be submitted to the National Institute of Health Research.

Vitamin A is thought to encourage regeneration of smell receptors in the nose when applied directly in the form of drops, as was seen in a recent German study.

However, a carefully designed trial is needed to show if this treatment works any better than a placebo.

The trial will be run by Professor Carl Philpott and the Norwich Clinical Trials Unit at four sites around the UK.

If you have any questions about this survey or the proposed study, please contact Professor Carl Philpott,

This survey is anonymous, and is being hosted by Norwich Clinical Trials Unit.
