I did find, like CalGal, a link between Omeprazole and a cough, and it was also causing itchy skin down my spine area. Changing my PPI to
Lansoprazole recently has not made the slightest
difference,
and I continue to cough all day and all night, a dry, irritating cough.
I also have gastritis, oesophagitis, a Hiatus hernia, none of which had been symptomatic other than nausea, and a lack of desire to eat.
