Once diagnosed with trachoma, not only is it necessary to use local eye drops, but also systemic treatment is required. Commonly used local eye drops for trachoma include 0.1% rifampin eye drops, 0.5% penicillin eye drops, yellow safety eye drops, tetracycline eye ointment, erythromycin eye ointment, sulfa eye ointment, and the treatment course needs at least ten to twelve weeks. In the acute phase or severe cases of trachoma, systemic antibiotic treatment is also needed, generally for three to four weeks. Adults take oral tetracycline, while it is contraindicated for pregnant women, nursing women, and children under seven years old, who may alternatively use erythromycin. Note: Medication should be used under the guidance of a doctor.
