Conjunctivitis generally requires appropriate treatment measures for the cause: bacterial conjunctivitis can be treated with topical antibiotics (levofloxacin, etc.), viral conjunctivitis can be relieved with antiviral medications (ganciclovir), and allergic conjunctivitis can be considered to be treated with antihistamines (loratadine). 1. Use of antibiotics: If the conjunctivitis is caused by bacterial infection, it can be treated with broad-spectrum antibiotics such as levofloxacin and tobramycin eye drops as prescribed by the doctor. 2. Use of antiviral drugs: If the conjunctivitis is caused by viral infection, you can consult a professional doctor and follow the doctor’s instructions to use ganciclovir, acyclovir and other antiviral drugs such as eye drops to relieve the symptoms. 3. Antihistamines: If the conjunctivitis is caused by allergy, you can consider using antihistamines such as loratadine and diphenhydramine to relieve the clinical discomfort. Conjunctivitis patients need to follow the doctor’s instructions in the treatment process, pay attention to personal eye hygiene.
