Here are a few options to consider for treating blepharitis and keratitis secondary to acne rosacea in a 3-month pregnant female:
1. Emphasize aggressive lid hygiene with warm compresses several times daily. This can help reduce inflammation without medications.
2. Consider a short course (1-2 weeks) of topical corticosteroid under close monitoring, as the benefits may outweigh the risks for a very limited period.
3. Topical azithromycin or bacitracin/polymyxin B ointment could provide antibiotic coverage without systemic absorption.
4. Consult dermatology for alternative oral antibiotic options safe in pregnancy like erythromycin
