Loratadine is actually generic Claritin which is an antihistamine for allergies.
Heartburn meds would be antacids such as Tums, Rolaids, Mylanta, Maalox. Pepcid (famotidine) Zantac (ranitidine) Prilosec OTC (omeprazole)
You are of course quite correct, it is omeprazole that I use for heartburn it works well for me. My wife like the loratidine for her hayfever.
Thanks for fixing it for me
