Overview

Pharmacologic medical therapies for blepharitis include either antimicrobial drops or ointments. Azithromycin is the preferred regimen for empiric therapy. Specific treatment for blepharitis depends on the causative pathogen and whether there is an underlying cause (dry eye, ocular rosacea, or meibomian gland dysfunction).

Medical Therapy

• 1. Empiric antimicrobial therapy

• Blepharitis

• Preferred regimen: Azithromycin 1% ophthalmic solution bid for 2 days followed by qd for 12-26 days
• Alternative regimen (1): Tobramycin/Dexamethasone 0.3%/0.05% ophthalmic suspension qid for 2 weeks

• 2. Specific considerations

• 2.1 Meibomian gland dysfunction:

• Preferred regimen: Doxycycline 100 mg PO qd until clinical improvement followed by 40 mg PO qd for 2-6 weeks OR Minocycline 100 mg PO qd until clinical improvement followed by 50 mg PO for 2-6 weeks OR Tetracycline 1000 mg PO until clinical improvement followed by 250-500 mg PO qd for 2-6 weeks.
