Brief summary

The purpose of this study is to assess the efficacy of N-acetylcysteine (NAC) in preventing those with mild or moderate COVID-19 from progressing to severe disease

Detailed description

After being informed of the study and potential risks and benefits, patients meeting eligibility requirements will be randomized to receive oral N-acetylcysteine (NAC) as follows: Inpatients: * N-acetylcystine (NAC) 25 mg/kg PO (rounded up to the nearest 600 mg) q4hrs until discharge * N-acetylcysteine (NAC) 1200 mg PO BID x 1 week post-discharge Outpatients: \- N-acetylcysteine (NAC) 2400 mg PO x 1 then 1200 mg PO BID x 2 weeks

Interventions

DRUGN-acetylcysteine

Oral formulation: 600 mg capsules of N-acetylcysteine
