A 25-year-old female asked:

Likely not: It really depends on the amount of bacteria getting into your system if the item you ate has it. Please remember: 1. Abx are NT to be considered preventative medicine. 2) Not every food item will have Listeria. 3) Go see the doctor if you think you have Listeria. Unpasteurized cheese, deli meats, and milk products are considered at risk foods.

Listeria and amox: Listeria is typically sensitive to amoxicillin. Though not recommended, having amoxillicin in your system can limit your risk of developing an internal infection. So, the antibiotics will likely work to prevent infection in you.

I agree that prophylactic antibiotics is not a recommend practice, especially in a young patient. The antibiotic received just so happens to cover Listeria.

A 43-year-old member asked:

Does dairy in formula increase the frequency of ear infections and congestion?

2 doctor answers4 doctors weighed in
Dr. Roy Benaroch
Pediatrics 27 years experience
No: That would be very rare. Dairy allergies can cause skin problems (hives or eczema), or more rarely gut problems (bloody diarrhea); there's also lactose intolerance, which occurs only in children and adults (never babies), which can cause diarrhea and abdominal pain. But food allergies very rarely cause nasal symptoms, congestion, or ear infections.

My baby is getting frequent ear infections. Is there any way to help prevent them?

Dr. Kathleen Forcier
Specializes in General Practice
Yes: Frequent ear infections are not only frustrating but can potentially affect language development. Breastfeeding, decreasing pacifier use, and giving your child the pneumococcal vaccine can all help prevent ear infections. Kids under 2 years old who have more than 3 ear infections in 6 months or more than 4 in 12 months may need to see an ear, nose and throat specialist.

Unlikely: With a large proportion of s. Pneumonii (most common bacteria causing middle ear infection) becoming resistant to penicillin, the mainstay of antibiotics treatment for "ear infection" is currently a high dose of amoxicillin.

Try Miralax (polyethylene glycol).: Miralax (polyethylene glycol) laxative powder is non habit forming and otc. 1 capful with any beverage daily may help with your regularity along with your fiber in your diet/fluids. 4 or more servings of fruits/veggies can help. Make sure you stool is soft and not hard, pellet like or large caliber. Neosporin ointment in the anal area 2 times dialy may improve you situation too.

Multiple reasons: Could be something as simple as anxiety or something pathology in the area. Would recommend seeing an ENT specialist to evaluate it.
