I found a more recently updated protocol (updated just this week, the other one was from back in January) for it here

For early outpatient protocol (COVID-19 positive), the Front Line COVID-19 Critical Care Working Group, FLCCC I-MASK+ protocol recommends (updated August 25, 2021):

• Ivermectin: 0.4–0.6 mg/kg per dose (take with or after meals) — one dose daily, take for 5 days or until recovered. (Find a Doctor). Use upper dose range if:  1) in regions with more aggressive variants; 2) treatment started on or after day 5 of symptoms or in pulmonary phase; or 3) multiple comorbidities/risk factors.

• Fluvoxamine: 50 mg twice daily for 10 days. Add to ivermectin if: 1) minimal response after 2 days of ivermectin; 2) in regions with more aggressive variants; 3) treatment started on or after day 5 of symptoms or in pulmonary phase; or 4) numerous co-morbidities/risk factors. Avoid if patient is already on an SSRI (selective serotonin reuptake inhibitor).

• Nitazoxanide: 500 mg 2 x daily for 5 days after meals. Combine with ivermectin (preferred) or substitute if ivermectin is not available. (Nitazoxanide is often unavailable or high-priced in the USA)

• Dual anti-androgen:

○ 1. Dutasteride 2 mg on day 1, followed by 1 mg daily for 10 days. therapy If dutasteride not available, use finasteride 10 mg daily for 10 days 

○ 2. Spironolactone 100 mg 2 x daily for ten days

• Vitamin D3: 4000 IU/day.

• Vitamin C: 500 - 1,000 mg BID (twice daily)

• Quercetin: 250 mg twice a day.

• Zinc: 100 mg/day. Zinc lozenges are preferred.

• Melatonin: 10 mg before bedtime (causes drowsiness).

• Antiviral mouthwash & iodine nasal spray -

○ Mouthwash: Gargle 3 x daily (do not swallow; must contain chlorhexidine,  povidone-iodine, or cetylpyridinium chloride). (e.g. Scope mouthwash™, Crest mouthwash, Colgate mouthwash, Betadine® Antiseptic Sore Throat Gargle)

○ Nasal Spray: Use 1 % povidone iodine commercial product as per instructions 2–3 x daily. If 1 %-product not available, must first dilute the more widely available 10 %-solution and apply 4–5 drops to each nose every 4 hours. (No more than 5 days in pregnancy.)

• Aspirin: 325 mg/day unless contraindicated.

• Pulse Oximeter: FLCCC also recommend monitoring your oxygen saturation with a pulse oximeter and to go to the hospital if you get below 94%.

• Monoclonal antibody therapy: Casirivimab/imdevimab: 600 mg each in a single subcutaneous injection for patients with one or more risk factors as follows: Age > 65y; obesity; pregnancy; chronic lung, heart, or kidney disease; diabetes; immunosuppressed; developmental disability; chronic tracheostomy; or feeding tub.

Notes:

• Optional: Betadine nasal spray applied 3 times per day.

• Optional: Curcumin: 500 mg twice a day (Ref)

• Duration for supplements: Most supplements (e.g. vitamin D, zinc, quercetin) for early treatment are given for 5 - 10 days. To continue for preventive purposes, dosages will need to be reduced as per the prevention or prophylaxis protocol.

• If you can’t get fluvoxamine (Luvox), using 30mg once a day of fluoxetine (Prozac) is equally effective (equivalent to 50mg twice a day of fluvoxamine).

• Optional: Azithromycin 250 mg twice a day. (Ref).

• Optional: Bromhexine 8 mg three times a day (Ref)
