Boric acid ear drops are not harmful. When the drops are put inside the patient’s ear, the patient may experience a burning pain, but don’t worry, it’s all normal. After finishing the drops and holding the position for 3-5 minutes, you can use your fingers to gently press the ear screen to help the drops go straight to the affected area faster. After treatment with ear drops, you can pour out the boric acid ear drops after soaking them in the ear for about 10 minutes. Patients are advised not to pull out their ears in general, as it is easy to push the secretions inside the ear deeper into the ear canal, making it even more difficult to remove them, which can cause tinnitus and even damage to the ear canal.
