Long COVID, also known as Post-Acute Sequelae of SARS-CoV-2 infection (PASC), continues to affect millions of people worldwide. As of 2024, researchers and clinicians have made significant strides in understanding and treating this complex condition. This article summarizes the most effective experimental treatments for long COVID based on recent clinical trials and research.
- Antiviral Therapies
Nirmatrelvir/ritonavir (Paxlovid) has shown promise in treating long COVID. A case study reported that a 5-day course of nirmatrelvir/ritonavir helped resolve PASC symptoms in a patient with persistent SARS-CoV-2 antigen positivity. This suggests that viral persistence may play a role in some cases of long COVID, and antiviral therapies could be beneficial.
- Immunomodulatory Treatments
Tocilizumab, an IL-6 receptor antagonist, has demonstrated potential in managing long COVID symptoms, particularly in patients with autoimmune conditions. The same case study showed that resuming tocilizumab treatment led to resolution of fatigue and brain fog, while decreasing the severity of headaches.
- Hyperbaric Oxygen Therapy (HBOT)
HBOT has shown promising results in treating long COVID, particularly for neurological symptoms. A study at the Sagol Center for Hyperbaric Medicine and Research in Tel Aviv found that HBOT improved blood flow in the brain and led to significant improvements in cognitive function for long COVID patients.
- Anticoagulation Therapies
Given the evidence of microclots in long COVID patients, anticoagulation therapies are being explored. The FLCCC I-RECOVER protocol recommends considering anticoagulants like nattokinase for patients with evidence of microclots.
- Intermittent Fasting and Autophagy Promotion
The FLCCC I-RECOVER protocol suggests intermittent daily fasting or periodic daily fasts to stimulate autophagy, which may help clear damaged cells and proteins, including spike proteins.
- Ivermectin
While controversial, ivermectin is being studied for its potential anti-inflammatory properties and ability to bind to spike proteins. Some clinicians report success in using it for long COVID treatment, particularly when combined with other therapies.
- Low-Dose Corticosteroids
For patients with ongoing respiratory symptoms and evidence of organizing pneumonia, low-dose corticosteroids (e.g., prednisolone or methylprednisolone) are being used to address persistent pulmonary inflammation.
- Mitochondrial Support
Supplements aimed at supporting mitochondrial function, such as Coenzyme Q10, L-carnitine, and alpha-lipoic acid, are being investigated for their potential to address fatigue and cognitive symptoms in long COVID patients.
- Gut Microbiome Modulation
Given the potential role of gut dysbiosis in long COVID, probiotics and other gut microbiome modulating therapies are being explored as potential treatments.
- Neurocognitive Rehabilitation
For patients with persistent cognitive symptoms, structured neurocognitive rehabilitation programs are being developed and tested to address “brain fog” and other neurological manifestations of long COVID.
It’s important to note that while these treatments show promise, many are still in experimental stages. A scoping review of registered clinical trials for long COVID treatments highlighted the need for more standardized definitions and approaches in studying this condition.
As research continues, it’s likely that a multi-modal approach, tailored to individual patient symptoms and underlying mechanisms, will prove most effective in treating long COVID. Patients should work closely with healthcare providers experienced in treating long COVID to develop personalized treatment plans.
The landscape of long COVID treatment is rapidly evolving, and it’s crucial for both patients and healthcare providers to stay informed about the latest research and treatment options. As more clinical trials are completed and data becomes available, our understanding and ability to treat long COVID will continue to improve.
