Introduction
Ear drops used to soften earwax (cerumen) are generally known as cerumenolytics. Commonly used types include sodium bicarbonate ear drops, hydrogen peroxide ear drops, boric acid ear drops, ofloxacin ear drops, and chloramphenicol ear drops (which also have softening effects). Sodium bicarbonate ear drops contain sodium bicarbonate as the main ingredient, which gently softens hardened earwax, making it looser and easier to remove, with minimal irritation.

Earwax (cerumen) softening solutions are commonly known as cerumenolytics. The most frequently used types include sodium bicarbonate ear drops, hydrogen peroxide ear drops, boric acid ear drops, ofloxacin ear drops (with softening effect), and chloramphenicol ear drops (with softening effect). A detailed analysis is as follows:

1. Sodium Bicarbonate Ear Drops: The main ingredient is sodium bicarbonate, which gently softens hardened earwax, making it looser and easier to remove. It has minimal irritation and is suitable for most people. Follow the instructions to instill the drops into the ear canal and keep them in place for a period to allow effectiveness.

2. Hydrogen Peroxide Ear Drops: Commonly known as hydrogen peroxide, these drops have dual functions of disinfection and earwax softening. They help break down hardened earwax in the ear canal while also killing certain bacteria. Suitable for cases with hard earwax accompanied by mild ear canal inflammation. A slight foaming sensation may occur during use.

3. Boric Acid Ear Drops: Boric acid provides moderate earwax softening effects and helps inhibit bacterial growth in the ear canal, maintaining cleanliness. Suitable for individuals with accumulated earwax and sensitive ear canal skin. Monitor for any adverse reactions after use.

4. Ofloxacin Ear Drops: Primarily used to treat ear infections, but their liquid formulation can also soften earwax to some extent. Suitable for cases where earwax blockage leads to mild infection. Should only be used when signs of infection are confirmed; avoid indiscriminate use.

5. Chloramphenicol Ear Drops: An antibiotic ear drop primarily used for treating infections, with an auxiliary effect in softening earwax. Suitable for cases of earwax impaction combined with bacterial infection. Dosage and duration must strictly follow medical advice or product instructions.

Before using earwax softening drops, ensure there is no damage or perforation in the ear canal to prevent irritation of the middle ear. If symptoms such as increased ear pain, worsening tinnitus, or hearing loss occur after application, seek medical attention promptly for professional earwax removal.

Did you add the medication to the nebulizer?
If a household or medical conventional compressor nebulizer is used, after adding the medication, the patient should use a mouthpiece (by holding the mouthpiece in the mouth) or a face mask (covering the mouth and nose) for nebulization; there is no need to cover the opening. This type of nebulizer converts liquid medication into aerosol droplets via airflow, which are then directly inhaled through the respiratory tract. An open port ensures smooth delivery of the aerosol droplets into the lungs, without affecting drug absorption efficacy.
