Hi there!
The common side effects of razo include abdominal pains, anxiety, arthralgia, fatigue, constipation, diarrhea, dry mouth, headache, myalgia, nausea, skin eruption, vomiting etc. Along with the medications & dietary changes, lifestyle modification is typically advised for adequate control of heartburn including regular exercise, avoiding smoking/ alcohol, sleeping with head slightly elevated etc. If there is no improvement observed with the changes along with the medication, other interventional/ surgical procedures may be considered as a part of management.
Hope this is helpful.
Take care!
