Not positive about this, but I think....
Betamethasone...should be betamethasone (generic)
Hydrocortisone... is correct (also generic)
Westcort... "seems to start with a W"...Bert, what would you prefer that it start with? I am not sure what WestOcort is, but Westcort seems right to me.
Rx Triamcinolone refers to the prescription form of the medication. It also comes in an OTC form, so this helps you differentiate.
Bert, I am only writing this in the hope that you can sleep a little better at night. :-)
