Famotidine use and quantitative symptom tracking in Covid patients: Case series

I have used famotidine as a prophylactic in the past(decades before covid year) when I realised there was a connection between my respiratory issues and GERD.

The GERD itself was seasonal. I initially tried ranitidine but famotidine(safe at low doses and no longer than 21 days at a time for me) was better. I tried explaining to my doctor who kept brushing me off. Eventually I quit telling her and sorted it out myself.

Worked fine for me. Having said that.. I am female. Frequent and very high doses of famotidine can cause ED for some. Cimetidine has the highest risk and ranitidine the lowest.

ETA for OTC ref in the US:

cimetidine aka tagamet, ranitidine aka zantac, famotidine aka Pepcid
