When preparing the drops, first wipe the secretions in the ear canal with a cotton swab to prevent the medication from being blocked for therapeutic purposes. In winter, it is best to put the medicine bottle in your hand for a few moments and warm it slightly before using it to avoid cold medicine stimulating the inner ear and causing vertigo and nausea. When applying the drops, turn your head upside down to one side with the diseased ear on top. Since the external ear canal has a certain curvature, adults should tug the auricle upwards and children downwards to straighten the ear canal so that the medicine can slowly flow into the ear along the wall of the ear canal. When there is more pus in acute and chronic otitis media, hydrogen peroxide is often used first to cleanse the pus in the deep part of the ear canal, and then antibiotic ear drops are put in. After the drops are applied, the affected ear should be kept in an upward head position for about 10 minutes. When applying the drops, the mouth of the dropper should not touch the ear to avoid contaminating the drops. The amount of medication to be put into the ear is usually 6 to 8 drops each time, 3 to 5 times a day. In case of inflammation, antimicrobial ear drops can be administered more than 10 times a day.
