Brief Summary:
The purpose of this study is to assess the efficacy of Xylitol plus Grapefruit Seed Extract (Xlear) nasal spray as an adjunct treatment of COVID-19.

Condition or disease Intervention/treatment Phase
Covid19 Drug: Nasal Spray Phase 3

Detailed Description:
After being informed about the study and potential risk, all patients giving written informed consent will undergo a brief screening period to determine eligibility for the study. Once eligibility is confirmed, patients who meet the eligibility requirements will be randomized placebo control manner. Patient will be assigned to Xlear (2 puffs per nosetrils, every 3-4 hours a day) or placebo. Patient will be followed for 1 week. Inflammatory markers will be obtained on Day 4 and repeat COVID-19 RT PCR on Day 7. Follow up will be done on Day 14 for all patients.

Primary Outcome Measures :
  1. Change from baseline reactive to non-reactive on COVID 19 RT PCR in 7 days [ Time Frame: Baseline and 7 days ]
