Welcome to the forum. Your mother is on clopidogrel
and you should consult the treating doctor before changing any medication. Let your mother get clinically assessed, alert the treating doctor with the symptoms from which she is suffering. Stomach irritation
may not necessarily be due to clavix-75.
Take care of the water she is taking and get more cautious about her diet. Consult a nutritionist regarding diet. Ensure your mother is not suffering from constipation
or gastric problems. She may need a few investigations.
You can consult s gastroenterologist also. Have a nice day, take care.
