This is Dr Basu, Experienced Specialist.
I am here to address your concerns and provide great service.
Nowadays we avoid PPIs like nexium for long term given several side effects like bone loss, atrial fibrillation, stomach and intestinal infections for example.
Safer options will be antacids like Gaviscon for daily long term use.
antac or ranitidine
also is considered safe to use for long term.
However there a long term safe supplement that can be used for gastritis.
This is known as DGL ( deglycirrhinized liquorice)
DGL is available in any health food stores without prscription.
The dosage is 2 tablets daily.
We also recommend regular check of liver and kidney functino by blood tests for any side effect.
Please discuss with your doctor also.
