Antibiotics for Crohn's disease
Antibiotics such as metronidazole (Flagyl) and ciprofloxacin (Cipro) have been used for treating Crohn's colitis. Flagyl also has been useful in treating anal fistulae in patients with Crohn's disease. The mechanism of action of these antibiotics in Crohn's disease is not well understood.
Metronidazole (Flagyl) is an antibiotic that is used for treating several infections caused by parasites (for example, giardia) and bacteria (for example, infections caused by anaerobic bacteria, and vaginal infections). It might have some activity in the treatment of Crohn's colitis and is particularly useful in treating patients with anal fistulae. Chronic use of metronidazole in doses higher than 1 gram daily can be associated with permanent nerve damage (peripheral neuropathy). The early symptoms of peripheral neuropathy are numbness and tingling in the fingertips, toes, and other parts of the extremities. Metronidazole should be stopped promptly if these symptoms appear. Metronidazole and alcohol together can cause severe nausea, vomiting, cramps, flushing, and headache. Patients taking metronidazole should avoid alcohol. Other side effects of metronidazole include nausea, headaches, loss of appetite, a metallic taste, and, rarely, a rash.
Ciprofloxacin (Cipro) is another antibiotic used in the treatment of Crohn's disease. It can be used in combination with metronidazole.
