If Olex ear drops are not available, it is best not to switch to another ear drop on your own because the right alternative depends on the cause of the ear discharge, whether the eardrum is intact, and the type of infection present. Prescription ear drops, such as ofloxacin-based drops, ciprofloxacin-based drops, or combinations containing antibiotics and anti-inflammatory medicines, may be commonly used, but the choice varies from patient to patient. Since you were prescribed Olex specifically, the safest option is to contact the prescribing doctor or pharmacist and ask for an equivalent brand with the same active ingredients rather than choosing a different medicine yourself. Until then, keep the ear dry, avoid putting oil, water, or cotton buds into the ear, and do not use over-the-counter ear drops without guidance, as some can be harmful if there is a perforation in the eardrum. If the discharge is increasing, there is severe pain, dizziness, swelling around the ear, or reduced hearing, you should seek medical attention promptly.
