Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Your husband seems to have developed acute gastroenteritis and needs antibiotic therapy. Severe cramping, as well as diarrhea and vomiting, are all symptoms of an infection.
He should follow a bland diet as of now, and make sure that he is drinking enough water. Also, in addition, a course of Tab. Ciprofloxacin 500 mg twice daily for 3 days will be helpful. If he's too gassy, then Simethicone ( Gas-X ) can be given for relief. He should also take probiotic capsules 2 daily for 3 days till the infection is controlled.
Feel free to discuss further,
Regards.
