Otic Anti-inflammatories
Anti-inflammatory drugs block substances in the body that cause inflammation. Otic anti-inflammatories are used for the treatment of superficial bacterial infections of the external auditory canal (i.e., otitis externa) caused by susceptible organisms. Anti-inflammatory medications frequently are administered in combination with antibiotics. A treatment response should occur within 48–72 hours, otherwise the provider should reassess (Medina-Blasini & Sharman, 2023).
Adverse Effects and Contraindications
Adverse effects are rare; however, clients can experience allergic reactions characterized by rash, itching, and redness. Dizziness may occur. Prolonged usage can result in a superinfection that requires additional medications to resolve.
Table 39.1 is a drug prototype table for otic anti-inflammatories featuring neomycin and polymyxin B sulfates, and hydrocortisone otic solution ( Cortisporin ). It lists drug class, mechanism of action, adult and pediatric dosage , indications, therapeutic effects, drug and food interactions, adverse effects, and contraindications.

Nursing Implications
The nurse should do the following for clients who are taking otic anti-inflammatories:
-
Recognize and monitor for serious and other potential side effects. Rarely, anaphylaxis can occur with the first dose.
- Clients with latex allergies may need to use an alternative (latex-free) dropper for administration.
- Perform hand hygiene before administering otic anti-inflammatory medication.
- Educate the client on ear position and time to remain in a lying position after instillation.
- Provide client teaching regarding the drug and when to call the health care provider. See below for client teaching guidelines.
Client Teaching Guidelines
The client taking an otic anti-inflammatory should:
- If this is the first time using these drugs, administer with another person present for assistance in case a serious allergic reaction occurs.
- Always wash their hands before handling a bottle of otic drops and be mindful of the bottle cap to ensure that it remains as germ-free as possible.
- Roll the bottle of otic drops between their hands for a few moments to warm the drops. Instillation of cold drops can cause dizziness.
- Administer the drops with the pinna in an upward position; it should remain up during otic drop instillation.
- Keep the ear facing up for about 5 minutes for the drop(s) to bathe the ear canal and minimize the amount of medication leakage (Mayo Clinic, 2023).
- Use a latex-free dropper if they have a latex allergy.
The client taking an otic anti-inflammatory should not:
- Heat the drops above body temperature because administering drops that are too warm can damage the ear canal.
- Drive or operate machinery until any occurrences of dizziness and vertigo have subsided.
- Use cotton swabs in their ears due to the risk of perforation and further irritation and injury (Cleveland Clinic, 2022a).
- Use the medication for longer than the prescribed duration.
Otic Topical Anti-infectives
Otic anti-infectives are indicated for clients who have otitis externa. Topical anti-infectives are prescribed to treat bacterial infections but are ineffective for viral infections. If the infection does not improve after 1 week of treatment, cultures and susceptibility tests should be repeated to verify the identity of the organism and to determine whether the therapy should be changed.
Table 39.2 lists common otic topical anti-infectives and typical routes and dosing for adult and pediatric clients .
| Drug | Routes and Dosage Ranges |

Client Teaching Guidelines
The client taking an otic topical anti-infective should:
- Report ear pain or worsening of itching to the health care provider; they may need an ear swab to test for superinfection if used for an extended period.
- Always wash their hands before handling a bottle of otic drops and be mindful of the bottle cap to ensure that it remains as germ-free as possible.
- Roll the bottle of otic drops between hands for a few moments to warm the drops. Instillation of cold drops can cause dizziness.
- Administer the drops with the pinna in an upward position; it should remain up during otic drop instillation.
- Keep the ear facing up for about 5 minutes for the drop(s) to bathe the ear canal and minimize the amount of medication leakage (Mayo Clinic, 2023).
The client taking an otic topical anti-infective should not:
- Warm the drops to greater than their body temperature because this can damage the ear.
- Drive or operate machinery until any occurrences of dizziness have subsided.
- Use cotton swabs in their ears due to the risk of perforation and further irritation and injury (Cleveland Clinic, 2022a).
Clinical Tip
This video from Tacoma Community College demonstrates the proper procedure for administering otic medication to an adult client.
For pediatric clients , review these instructions from the American Academy of Pediatrics .
Systemic Anti-infectives for Infections of the Ear
Systemic otic anti-infectives are indicated for clients who have otitis media. Acute otitis media in adults can cause significant complications; therefore, most adults are treated with antibiotic therapy (Limb et al., 2023). Antibiotic therapy is used more judiciously in children to avoid antibiotic resistance and side effects. High-dose amoxicillin is the first-line choice for both children and adults (Danishyar & Ashurst, 2023). If high-dose amoxicillin is not effective, high-dose amoxicillin-clavulanate is the second-line treatment. For clients with penicillin allergies or non-responders, azithromycin or cefdinir are two alternatives that can be considered.
Table 39.4 lists common otic systemic anti-infectives and typical routes and dosing for adult and pediatric clients .
| Drug | Routes and Dosage Ranges |
|---|---|

Adults: One 875 mg amoxicillin/125 mg potassium clavulanate tablet orally every 12 hours or one 500 mg amoxicillin/125 mg potassium clavulanate tablet orally every 8 hours. Children >40 kg: Use adult dosing. Children ≥3 months and weighing <40 kg: 45 mg/kg daily orally every 12 hours or 40 mg/kg daily every 8 hours (using 200 mg amoxicillin/28.5 mg potassium clavulanate mg per 5 mL or 400 mg amoxicillin/57 mg potassium clavulanate per 5 mL oral suspension). Children <3 months: 30 mg/kg daily orally every 12 hours (using 125 mg amoxicillin/31.25 mg potassium clavulanate mg per 5 mL oral suspension). |
|
Azithromycin
( Zithromax ) |
For children with acute otitis media (using oral suspension 500 mg in 5 mL):
Children ≥6 months: 30 mg/kg orally as a single dose, or 10 mg/kg once daily for 3 days, or 10 mg/kg as a single dose on day 1 followed by 5 mg/kg daily on days 2 through 5. |
|
Cefdinir

Adverse Effects and Contraindications
Systemic antibiotics can lead to diarrhea and possibly pseudomembranous colitis and Clostridium difficile infection. Symptoms of C. difficile can range from mild to life-threatening and may require hospitalization and extended therapy. Antibiotic-related diarrhea can occur up to 2 months after ceasing antibiotic therapy. Antibiotics can cause allergic reactions, especially in clients with other sensitivities.

Nursing Implications
The nurse should do the following for clients who are taking systemic anti-infectives for otic conditions:
- Recognize and monitor for serious and potential side effects including signs of allergic reactions and new onset of diarrhea.
- Follow dosing instructions carefully, particularly with amoxicillin-clavulanate (Augmentin). Different forms of Augmentin contain different amounts of amoxicillin but the same amounts of clavulanic acid, so the strengths are not interchangeable. For example, two 250 mg Augmentin tablets are not the equivalent of a 500 mg tablet. If a client is prescribed 500 mg, the client must take the 500 mg tablet, not two 250 mg tablets.
- Provide client teaching regarding the drug and when to call the health care provider. See below for client teaching guidelines.
Client Teaching Guidelines
The client taking an otic systemic anti-infective should:
- Report episodes of diarrhea to their health care provider.
- Take all their antibiotic(s) as prescribed.
- Keep follow-up appointments.
The client an otic systemic anti-infective should not:
- Share antibiotics with others.
