It is normal for your ear to still feel blocked after a 7-day treatment with the antibiotic Biaxin for an otitis with a perforated eardrum. Some people may continue to feel this sensation until the eardrum heals. Biaxin typically treats this type of infection well. If you are no longer experiencing a fever and are otherwise feeling well, it may not be necessary to see a doctor immediately. However, if your fever returns, it is advisable to seek medical advice. It is recommended to have a follow-up appointment with a doctor in the next 4 to 6 weeks to ensure that your eardrum is healing properly.
