Basics: What you need to know
Aspirin (Acetylsalicylic Acid, ASA) is a long-established non-steroidal anti-inflammatory and antiplatelet medication, chemically defined as C9H8O4, that has drawn recent attention from researchers studying the lingering symptoms and complications associated with Long Covid. By targeting inflammatory pathways and inhibiting platelet aggregation, this standardized pharmaceutical agent aims to address ongoing inflammation, blood clotting risks, and possible microclot formation in patients. While it is widely available, the focus here is on the precisely controlled formulation tested in clinical practice, rather than over-the-counter usage, with particular emphasis on its standardized dosages (e.g., 81 mg or 325 mg) and well-defined therapeutic scope.
History and development
- Ancient roots: Its origins trace back to willow bark extracts used medicinally for centuries, containing salicin, a natural precursor to aspirin.
- Modern synthesis: Felix Hoffmann, working at Bayer in 1897, chemically modified salicylic acid to produce acetylsalicylic acid, creating a more tolerable and consistent drug.
- Key discovery: Sir John Vane identified aspirin’s action on prostaglandins in the 1970s, illuminating its anti-inflammatory and antiplatelet mechanisms.
- Evolving roles: Over time, aspirin’s applications expanded beyond pain relief to include prevention of heart attacks and strokes through platelet inhibition, setting the stage for current research in inflammatory and microvascular conditions.
What is known
- Inflammation control: Aspirin reduces levels of prostaglandins, potentially mitigating the persistent systemic inflammation reported in certain Long Covid cases.
- Platelet inhibition: Its antiplatelet effects may help lessen microthrombotic processes thought to play a role in ongoing symptoms.
- Standardized doses: Specific clinical protocols often require low-dose (81 mg) or standard-dose (325 mg) regimens, though precise recommendations are still developing.
- Symptom targeting: Some patients report improved energy levels or reduced severity of chest pain and shortness of breath, possibly due to minimization of clotting or inflammation.
What is not known
- Long-term impact: The optimal duration of therapy and the full extent of long-term side effects or benefits in Long Covid remain unclear.
- Dose consensus: There is no absolute consensus on whether a low or standard dose yields the best outcomes for different patient profiles.
- Mechanistic clarity: Research is still ongoing to clarify how fully aspirin can address microclots linked to Long Covid, including the interplay between inflammation and vascular changes.
- Individual variation: Factors such as genetic predisposition, comorbidities, and medication interactions can influence its effectiveness, and current data do not capture all patient subgroups comprehensively.
- Reduces prostaglandins by blocking cyclooxygenase enzymes, decreasing inflammation.
- Inhibits platelet function to diminish aggregation and microclot formation.
- Stabilizes vascular response through modulation of inflammatory mediators and improved blood flow.
- Gastrointestinal irritation which can lead to ulcers or discomfort.
- Bleeding tendencies due to reduced platelet aggregation.
- Allergic reactions in some individuals with aspirin sensitivity.
- Varied response: Some clinicians endorse it for vascular symptoms, while others find limited efficacy.
- Insufficient data: Ongoing trials have yet to provide definitive outcome measures.
- Risk-benefit balance: Some worry about gastrointestinal or bleeding risks outweighing potential gains.
Patient views
Experiences
- Patients appreciate aspirin's ability to reduce inflammation and improve symptoms like fatigue, headaches, and brain fog.
- Many report significant relief from cardiac symptoms, including palpitations and chest tightness.
- Aspirin is often praised for its role in addressing microclots, a suspected cause of Long Covid symptoms.
- Some patients find aspirin improves their quality of life, even if it doesn't fully resolve their condition.
Challenges
- Long-term use of aspirin raises concerns about potential side effects like stomach issues or ulcers.
- High doses of aspirin can lead to nausea or exacerbate conditions like asthma.
- Some patients feel aspirin alone isn't enough to address severe symptoms or microclots.
- Risks of bleeding and other complications make aspirin therapy potentially dangerous without medical supervision.
Tips
- Consult a doctor before starting aspirin therapy, especially for high doses.
- Pair aspirin with a proton pump inhibitor (PPI) to protect the stomach from ulcers.
- Start with low doses and gradually adjust to find the minimum effective amount.
- Monitor for side effects like nausea or asthma flare-ups and adjust treatment accordingly.

Patient view
I was taking aspirin for a bit and it definitely helped but don’t want to take it long term.

Patient view
Also taking a baby aspirin 81mg morning after eating and before bed and it doesn’t solve everything but makes me anywhere from 30%-80% better depending on the day. I know it’s not great to take long term and will be talking to my doctor soon about other anti-inflammatories that could be a possibility, but for now the reward is worth the risk to me.

Dr. Asad Khan discusses the use of aspirin as part of a three-drug combination to treat Long Covid symptoms, particularly those related to clot formation. He explains that aspirin, along with clopidogrel and another anticoagulant like heparin or apixaban, targets different parts of the clotting pathway. This approach has shown promise in reducing the need for repeated cycles of apheresis, a blood filtration treatment. Dr. Khan notes that while the treatment is intense, it has led to significant improvements in his condition, especially after adding the three-drug combination.

Expert view
Dr. Derya Unutmaz, a professor at NYU Langone Medical Center, discusses the potential of aspirin as a treatment for chronic inflammation, including its role in conditions like Long Covid and ME/CFS. He mentions ongoing trials to determine if taking a small daily dose of aspirin can reduce inflammation. However, he emphasizes that current evidence is anecdotal and not definitive. Dr. Unutmaz advises against recommending aspirin for these conditions until more data is available, stressing the importance of understanding individual immune profiles and the heterogeneity in responses to treatments.

Research
This paper explored treatments for vascular damage and abnormal blood clotting associated with Long COVID, focusing on small molecules and their therapeutic potential. It reviewed patent literature from the last two years and included evidence from preclinical and clinical studies.
The study highlighted several small molecules, including aspirin, ramatroban, emricasan, and rimeporide, as potential treatments for Long COVID-related complications. While aspirin and other antiplatelet agents were noted, their impact on morbidity and mortality remains unproven.
For individuals with Long COVID, this paper suggests that aspirin and other small molecules might help manage vascular and clotting issues, though their effectiveness is still uncertain. It provides hope for future targeted treatments but emphasizes the need for more research.
The paper is a literature review published in the reputable journal 'Viruses,' which specializes in virology and related fields. However, as a review, it relies on existing studies and patents rather than presenting new experimental data.
