Ear drops in clinical practice include many kinds of drops, such as levofloxacin hydrochloride ear drops, ofloxacin ear drops, lomefloxacin hydrochloride ear drops, sodium bicarbonate ear drops, ciprofloxacin ear drops and so on. Patients can apply them selectively according to their conditions, or they can use them under the guidance of a doctor. Patients should lie on their side with the affected ear facing upwards when taking an ear bath. After putting the ear drops in the ear canal, they should then tug the ear with great force, which will facilitate the local contact between the ear drops and the skin of the ear canal and can effectively play the role of anti-inflammatory and swelling reduction or cerumen softening. It is best to apply the ear drops 2-3 times a day and soak them for about 10 minutes each time in order to give full play to their medicinal effects. After active treatment, the patient’s condition should improve significantly. You should pay attention to protecting your ears during your life and avoid getting water all the time so as not to cause infection.
