Usage
Beclometasone + Ofloxacin is primarily prescribed for the treatment of ear infections (otitis externa and otitis media). It is a combination medication with a corticosteroid and antibiotic. It reduces inflammation and combats bacterial infections.
Alternate Names
While “Beclometasone + Ofloxacin” is the standard generic name, some regional or international variations may exist. Brand names for this combination product vary and can include “Amcure-O”, “Myclin O”, and “Audicare”.
How It Works
Pharmacodynamics: Beclometasone, a corticosteroid, exerts anti-inflammatory action by binding to glucocorticoid receptors. This reduces the production of inflammatory mediators. Ofloxacin, a fluoroquinolone antibiotic, inhibits bacterial DNA gyrase and topoisomerase IV, essential enzymes for bacterial DNA replication and repair.
Pharmacokinetics: When administered as ear drops, both drugs have minimal systemic absorption. Ofloxacin that is absorbed systemically is primarily eliminated via renal excretion. Beclometasone is metabolized by hydrolysis.
Dosage
Standard Dosage
Adults: 2-5 drops in the affected ear 3-4 times daily for 7-14 days.
Children: Pediatric dosing varies by age and should be determined by a physician. Generally, children under 12 should not use this medication due to the presence of Ofloxacin.
Special Cases:
- Elderly Patients: Dose adjustments may be necessary depending on renal function.
- Patients with Renal Impairment: Dose adjustments are required for creatinine clearance <50 mL/min.
- Patients with Hepatic Dysfunction: Use with caution and monitor for systemic side effects. Dosage adjustments may be necessary.
- Patients with Comorbid Conditions: Caution for patients with diabetes; blood glucose levels should be monitored.
Clinical Use Cases
Beclometasone + Ofloxacin ear drops are not typically indicated for intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations.
Dosage Adjustments
Dose modifications may be required based on renal and hepatic function, as well as other patient-specific factors.
Side Effects
Common Side Effects:
Ear discomfort, irritation, stinging, itching, redness, dryness.
Rare but Serious Side Effects:
Allergic reactions, hearing loss, visual disturbances, Stevens-Johnson syndrome.
Long-Term Effects:
With topical administration, long-term systemic effects are unlikely. Prolonged use may lead to overgrowth of non-susceptible organisms.
Adverse Drug Reactions (ADR):
Severe allergic reactions require immediate medical attention.
Contraindications
Hypersensitivity to beclometasone, ofloxacin, or any component of the formulation. Hypersensitivity to other corticosteroids or quinolones. Viral infections of the ear (e.g., herpes simplex, varicella). Fungal infections of the ear (unless used as part of a combination therapy addressing the fungal infection). Tympanic membrane perforation (for some formulations).
Drug Interactions
Consult drug interaction databases for the most up-to-date information. Potential interactions may exist with certain medications, including some NSAIDs, anticoagulants, and drugs that affect CYP450 enzymes. Alcohol and some foods may interact with ofloxacin. Beclometasone may interact with certain drugs that induce CYP3A4 enzymes, potentially affecting its clearance.
Pregnancy and Breastfeeding
Safety during pregnancy and breastfeeding has not been fully established. Topical application minimizes systemic absorption, but a small amount of the drugs may be passed to the fetus or infant. Weigh the potential benefits against potential risks. It is advisable to consult with a specialist and refer to resources such as the Best Use of Medicines in Pregnancy (BUMPS) website for the latest guidelines.
Drug Profile Summary

- Pregnancy & Breastfeeding: Safety not fully established; use with caution. Consult specialist and dedicated resources for guidance.
- Dosage: Adults: 2-5 drops 3-4 times daily for 7-14 days; Children: Dosage varies by age; consult specific pediatric guidelines and avoid in those under 12.
- Monitoring Parameters: Treatment response, adverse reactions, signs of superinfection (secondary infection), serum creatinine (renal function), liver function tests, serum glucose (diabetics), and, in some cases, EKG.
Popular Combinations
Beclometasone and Ofloxacin are often combined with Clotrimazole (antifungal) and Lidocaine (local anesthetic) for broader coverage of ear infections with diverse microbial etiology.
Precautions
- General Precautions: Pre-screening for allergies, metabolic disorders, organ dysfunction (particularly liver and kidney). Evaluate for tympanic membrane perforation.
- Specific Populations:
- Pregnant Women: Consult specialist and assess risks vs. benefits.
- Breastfeeding Mothers: Consult specialist and assess risks vs. benefits.
- Children & Elderly: Caution and potential dose adjustments. In general, avoid use in children under 12.
- Lifestyle Considerations: Limit alcohol, as it may interact with ofloxacin.
FAQs (Frequently Asked Questions)
A: The standard adult dosage is 2-5 drops in the affected ear 3-4 times a day for 7-14 days. Pediatric dosing varies and should be determined by a physician.
Q2: Can these ear drops be used if the eardrum is perforated?
A: This is generally contraindicated, except in specific cases of chronic suppurative otitis media (CSOM) under careful medical supervision. Consult an ENT specialist.
Q3: What are the most common side effects?
A: Common side effects include local reactions such as ear discomfort, irritation, stinging, itching, redness, and dryness.
Q4: What are the serious side effects I should watch out for?
A: Rare but serious side effects can include allergic reactions, hearing loss, visual disturbances (though rare with ear drops), and Stevens-Johnson syndrome. Seek immediate medical attention if these occur.
Q5: Are there any drug interactions I should be aware of?
A: Yes, potential interactions exist with certain medications, including some NSAIDs, anticoagulants, and drugs that affect CYP450 enzymes (Ofloxacin). Consult a drug interaction database or pharmacist for specific guidance.
Q6: Can I use these ear drops during pregnancy or while breastfeeding?
A: Safety during pregnancy and breastfeeding hasn’t been fully established. Topical application minimizes systemic absorption, but consult a specialist to evaluate the risks versus benefits.
A: Beclometasone reduces inflammation, while Ofloxacin eliminates the bacteria causing the infection.
Q8: What should I do if I miss a dose?
A: If you miss a dose, instill it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose.
Q9: How long should I use these ear drops?
A: Typically, treatment lasts 7-14 days. Follow your physician’s instructions. Prolonged use can lead to the overgrowth of resistant organisms.
