On the Treatment of Covid-19
Updated: November 16, 2020; Published: July 2, 2020
Immunological and serological studies show that most people develop only mild or moderate symptoms when infected with the new coronavirus, while some people may experience a more pronounced or critical course of the disease (read more).
Based on the available scientific evidence and current clinical experience, the SPR Collaboration recommends that physicians and authorities consider the following covid-19 treatment protocol for the prophylactic and early treatment of people at high risk or high exposure.
According to numerous international studies, the risk of severe or fatal disease may be significantly reduced by prophylactic or early treatment (see scientific references below).
Note: Patients are asked to consult a doctor.
- Zinc (25mg to 50mg per day)
- Quercetin (250mg to 500mg per day)
- Bromhexine (25mg to 50mg per day)
- Vitamins D (2000 u/d) and C (1000mg)
- Aspirin (80mg to 100mg per day)*
- Zinc (75mg to 150mg per day)
- Quercetin (500mg to 1000mg per day)
- Bromhexine (50mg to 100mg per day)
- Vitamins D (5000 u/d) and C (1000mg)
- Aspirin (162mg to 325mg per day)*
- Ivermectin (0.2 mg/kg daily for two days)*
- High-dose vitamin D (up to 100,000 IU)
- Azithromycin (up to 500mg per day)
- Prednisone (60mg to 80mg per day)*
- Heparin LMW (usual dosage)
*) Notes: Contraindications for aspirin must be observed, especially if used prophylactically. Ivermectin may also be used prophylactically on a weekly basis (see below). Prednisone is to be used if pulmonary and respiratory symptoms develop.
Note on hydroxychloroquine (HCQ): Correctly dosed HCQ, a drug against malaria and auto-immune disease, has also been shown to be safe and effective for the early treatment of covid-19 in numerous studies. HCQ has known anti-viral, anti-thrombotic and anti-inflammatory properties.

- US physicians reported an 84% decrease in hospitalizations, a 45% decrease in mortality among already hospitalized patients, and an improvement in the condition of patients within 8 to 12 hours based on early treatment with zinc in addition to HCQ.
- A Spanish study found that low plasma zinc levels (below 50mcg/dl) increased the risk of in-hospital death of covid patients by 130%.
- A US study reported a rapid resolution (within hours) of covid symptoms, such as shortness of breath, based on early outpatient treatment with high-dose zinc.
- Ivermectin has shown strong anti-viral and anti-inflammatory effects in numerous controlled and observational studies, reducing covid mortality even in severe cases by up to 90%.
- Based on these results, the US Front-Line Covid-19 Critical Care Alliance (FLCCC) recommends ivermectin for covid-19 prophylaxis and early treatment.
- Iranian doctors reported in a study with 78 patients a decrease in intensive care treatments of 82%, a decrease in intubations of 89%, and a decrease in deaths of 100%.
- Chinese doctors reported a 50% reduction in intubations due to bromhexine treatment.
- A German study discusses the efficacy of bromhexine based on biochemical aspects.
- In a Spanish randomized controlled trial (RCT), high-dose vitamin D (100,000 IU) reduced the risk of requiring intensive care by 96%.
- A study in a French nursing home found an 89% decrease in mortality in residents who had received high-dose vitamin D either shortly before or during covid-19 disease.
- A large Israeli study found a strong link between vitamin D deficiency and covid-19 severity.
- A 2017 meta-study found a positive effect of vitamin D on respiratory tract infections.
- A US study showed that aspirin has a strong antiplatelet and anticoagulant effect in covid patients, which could help prevent infection-related thrombosis, embolism and stroke.
- The US FLCCC Alliance recommends aspirin for prophylactic and early treatment.
- Zinc inhibits RNA polymerase activity of coronaviruses and thus blocks virus replication, as first discovered by world-leading SARS virologist Ralph Baric in 2010.
- Quercetin supports the cellular absorption of zinc and has additional anti-viral properties, as first discovered during the SARS-1 epidemic in 2003.
- Ivermectin (an antiparasitic drug) has broad anti-viral and anti-inflammatory properties.
- Bromhexine (a mucolytic cough medication) inhibits the expression of cellular TMPRSS2 protease and thus the entry of the virus into the cell, as first described in 2017.
- Vitamins C and D support and improve the immune system response.
- Azithromycin (an antibiotic) prevents bacterial superinfections of the lung.
- Prednisone (a corticosteroid) reduces covid-related systemic inflammation.
- Aspirin may help prevent infection-related thrombosis and embolisms in patients at risk.

The early treatment of patients as soon as the first typical symptoms appear and even without a PCR test is essential to prevent progression of the disease. In contrast, isolating infected high-risk patients at home and without early treatment until they develop serious respiratory problems, as often happened during lockdowns, may be counterproductive.
People at high risk living in an epidemically active area should consider prophylactic treatment together with their doctor. The reason for this is the long incubation period of covid-19 (up to 14 days): when patients first notice that they contracted the disease, the viral load is already at a maximum and there are often only a few days left to react with an early treatment intervention.
Early treatment based on the above protocol is intended to avoid hospitalization. If hospitalization nevertheless becomes necessary, experienced ICU doctors recommend avoiding invasive ventilation (intubation) whenever possible and using oxygen therapy (HFNC) instead.
It is conceivable that the above treatment protocol, which is simple, safe and inexpensive, could render more complex medications, vaccinations, and other measures largely obsolete.
