Treatment for Shigella Infection
Although shigellosis is usually a self-limited illness, antibiotics can shorten the course, and in the most serious cases, might be life saving. When oral therapy is adequate, a fluoroquinolone antibiotic is the recommended first-line treatment for non-pregnant adults (Gilbert, Moellering & Sande, 2001). Ciprofloxacin 500 mg twice daily for three days is often prescribed. Alternative antimicrobial agents include trimethoprim-sulfamethoxazole, azithromycin, and ceftriaxone.
If you believe you have become ill with Shigellosis, contact your healthcare provider, who will be able to prescribe the best course of treatment.
The bacteria remain active during the illness and for a week or two after an infected individual recovers. It’s possible for a person to carry Shigella without developing symptoms, but then pass the illness to others (Mayo Clinic, 2007, April 14).
