Official title

Efficacy of Adjunctive Sodium Citrate in Smell Retraining for People With Post-Acute Sequelae COVID-19 Olfactory Dysfunction

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this pilot study is to assess the feasibility and impact of using sodium citrate nasal spray as an adjunct to olfactory retraining in participants with long-term post-COVID-19 olfactory dysfunction. The main questions it aims to answer are: * Is sodium citrate nasal spray in addition to smell retraining feasible for participants to use in terms of participant need/desire, adherence, and adverse events? * Does sodium citrate nasal spray in addition to smell retraining further improve smell as compared to normal saline spray and smell retraining? Participants will: * Provide consent for enrollment. * Undergo smell testing via Sniffin' Sticks. * Use a nasal spray (either sodium citrate or normal saline) followed by olfactory retraining twice a day for 12 weeks. * Return for follow-up Sniffin' Sticks testing. Researchers will compare the sodium citrate group and the normal saline group to determine differences in smell improvement.
