Yes, taking these prescribed medications is a recognised medical approach for mild, uncomplicated appendicitis. Your doctor has prescribed two antibiotics, Rifastop (rifaximin) and faropenem, to target the infection, and an acid reducer (rabeprazole) to protect your stomach. This conservative, non-surgical treatment can be highly effective. It is safe to take them exactly as directed. However, because appendicitis requires careful monitoring, please watch your symptoms closely. If you experience worsening abdominal pain, fever, or vomiting, seek immediate medical attention, as surgical evaluation may then be necessary. Keep in close contact with your doctor.
