Hello. Thank you for posting.
Generally, both are given. Let your doctor know that you cannot take Flagyl.
Diverticulitis is an out-pouching in the colon that subsequently becomes inflamed or infected. It can cause diarrhea, constipation, nausea, vomiting, pain, fever or bleeding. The treatment depends upon how severe the symptoms are and if it is the first attack.
The underlying inflammation and infection are initially treated with a broad-spectrum antibiotic that covers anaerobic and gram-negative rod bacteria. Diverticulitis infections usually have multiple bacteria, which fall into the category of anaerobic and gram-negative bacilli. Oral antibiotics for an outpatient treatment protocol most often include amoxicillin, ciprofloxacin (Cipro), moxifloxacin or metronidazole (Flagyl). Patients must take these antibiotics for the prescribed duration of time.
