Back at the beginning I thought they said Pepcid helped.
I’ve read Pepcid AC is a channel blocker and Claritin is another kind of channel blocker (for a different channel), and if you were taking both daily you’d reduce the number of places the spikes can attach, thereby giving the body a chance to clear spike proteins without the damage that can result if they attach. (or was it the virus itself has fewer attachments?)
I’m sorry I can’t recall for sure if it’s spike or viruses which have a harder time attaching, but I’ve seen claims these two different OTC meds help with Covid for about a year now.
