“Is there something better than tamiflu?”—Thank you for posing this question, I enjoyed researching it.
I’m going to propose two candidates that could be superior against H5N1: Aspirin (acetylsalicylic acid) and Methylene blue (methylthioninium chloride).
Aspirin
First, consider aspirin’s safety profile. For short-term use—relevant in acute infections—the risks are minimal for most individuals. GI upset, often cited as a concern, is only marginally higher than placebo (source: PMC3586117). The notable exception is its association with Reye’s syndrome in children, but this is exceptionally rare. The risk-benefit calculus remains favorable for adults, particularly in acute scenarios.
Efficacy-wise, aspirin’s NF-κB-inhibiting activity shows promise as an antiviral. It has demonstrated robust effects against H5N1 in vitro and in vivo (source: Wiley). This pathway is a compelling mechanism of action that Tamiflu does not directly address, positioning aspirin as a strong candidate for consideration.
Methylene blue
Next, methylene blue is another plausible alternative. Its safety profile for short-term use is generally acceptable, barring contraindications such as risk of serotonin syndrome, hypersensitivity, or severe renal impairment (source: Medsafe). For those without contraindications, it represents a well-tolerated option.
Methylene blue’s broad-spectrum antiviral properties are underappreciated. It has shown potent virucidal activity against H1N1 (source: PMC8275569), and while H5N1-specific data is lacking, the mechanism of action suggests potential efficacy. Notably, there’s already a patent application exploring its antiviral indications (source: WO2007086995A2). Given this, methylene blue is a viable contender worthy of further clinical study.
Comparing with Tamiflu
Tamiflu has well-documented side effects—nausea, vomiting, diarrhea, and abdominal pain—that overlap with the profiles of both aspirin and methylene blue (source: Medsafe Tamiflu). While tolerable for most, its mild benefits against H5N1 are unlikely to significantly outperform the mechanistic potential of aspirin or methylene blue (source: JHEOR).
Conclusion
In a pandemic preparedness scenario, Aspirin and Methylene blue deserve serious consideration alongside Tamiflu. They offer distinct mechanisms of action, robust preliminary data, and manageable safety profiles. If you’re prioritizing interventions that maximize cost-effectiveness and theoretical efficacy, these “old drugs” might hold the key to new antiviral strategies. Rational prioritization of research and clinical trials could unlock their full potential.

Why is reference to further clinical study weird? It is a credible alternative not a mainstream, thoroughly researched alternative.
