Ear Infections - Medications

(Page 4)

First-line treatment for severe AOM:

• Amoxicillin-clavulanate (Augmentin). This antibiotic is known as an augmented penicillin. It works against a wide spectrum of bacteria and is administered orally.

Second-line treatment for severe AOM:

• Ceftriaxone. Ceftriaxone (Rocephin) is an injectable cephalosporin that may be prescribed as an alternative to amoxicillin-clavulanate, especially for children who have vomiting or other conditions that hamper oral administration.
• Tympanocentesis or clindamycin. Patients with severe AOM who have failed to respond to amoxicillin-clavulanate after 48 to 72 hours may require the withdrawal of fluid from the ear (tympanocentesis) in order to identify the bacterial strain causing the infection. If tympanocentesis cannot be performed, clindamycin may be prescribed orally to treat penicillin-resistant pathogens that have not responded to prior drug therapy.

Side Effects of Antibiotics

• The most common side effects of nearly all antibiotics are gastrointestinal problems, including cramps, nausea, vomiting, and diarrhea. This can be a significant problem in infants and small children. One study reported that giving such children a soy-based formula that contained fiber (Isomil DF) was helpful in reducing these side effects.
• Amoxicillin use during infancy may lead to enamel defects and discolorations of permanent teeth
• Allergic reactions can also occur with all antibiotics but are most common with medications derived from penicillin or sulfa. These reactions can range from mild skin rashes to rare but severe, even life-threatening anaphylactic shock.
• Some drugs, including certain over-the-counter medications, interact with antibiotics; parents should tell the doctor about all medications their children are taking.
