Peroxide drops. 3% hydrogen peroxide drops are one of the options we use to help break up impacted cerumen or earwax in patients who clean their ear and end up pushing it deep into the canal or up against their eardrum, resulting in muffled or decreased hearing +/- ear pain. Only a few drops are needed. Application and follow up should be as directed by your ent. You should have an intact eardrum.
Possible damage. Pouring peroxide into your ear canal is not recommended and can cause scarring of the ear drum.
