If the drops are being used prior to an ear syringing appointment, the surgery will advise on the recommended dosing.

This will not stop wax collecting, but will make removal easier and encourage the natural movement of wax from the outer ear.Cerumol Olive Oil Ear Drops are a medicinal grade olive oil (Extra Virgin Olive Oil Ph.Eur.100% v/v) specified for use in ear drops. The olive oil used has not been chemically processed or refined and so (unlike most other olive oil products on the market) is of the highest standard.
