Found Cetirizine HCL tablets, 10 mg, 14 in a package for a buck. Since the protocol says Cetirizin OR Loratadine, not AND, I should now have enough for 7 days of treatment.
I see no reason to take the antibiotics.
What does the dexchlorpheniramine (normally) do?
I do sometimes take a Phenylephrine HCL 10 mg tablet to unplug a plugged nose. It works, sort-of, most of the time. I would prefer phenylpropanalamine, but they took that off the market decades ago.
I also have taken the generic Tylinol, but mostly switched to Ibuprofin as the former seemed to have lost some effectiveness. I have a supply of both.
There don't currently seem to be any attempts to stop people from buying the two allergy pills. Meijer had an aisle-end packed with their generic version of Zyrtec, and some of their generic Claratin, tonight.
