Ear antiseptic (acidifies the ear canal)

Acetic acid (ear drops and spray) (حمض الأسيتيك)

Acetic acid ear drops or spray make the outer ear canal slightly acidic, so bacteria and fungi find it harder to grow. They are used for mild outer ear infections.

What it is used for

  • Mild infection or inflammation of the outer ear canal (swimmer's ear)
  • Helping to prevent outer ear infections coming back in people often exposed to water, if a doctor or pharmacist advises

How it is used

  • Use it in the ear only, as the leaflet says or as your doctor or pharmacist advises
  • Tilt your head so the affected ear faces up, put the drops or spray into the canal, and stay in that position for a short while
  • Do not touch the ear with the tip of the bottle, and keep the ear dry during treatment

Possible side effects

  • Mild stinging or burning in the ear when applied
  • Rarely, irritation or allergy in the ear

Who should not use it

  • A hole in the eardrum or grommets (ear tubes)
  • Allergy to any ingredient in the product

Before and while using it

  • See a doctor if the ear does not improve within a short time, or if there is discharge, fever, severe pain or hearing loss
  • Stop it if the stinging or irritation gets worse
  • For the ear only; do not swallow it or put it in the eye

Medicine interactions

  • Do not use other ear drops at the same time unless your doctor or pharmacist advises it

Pregnancy and breastfeeding

  • Use in the ear is not expected to cause harm in pregnancy or breastfeeding; ask your pharmacist first

How to store it

  • Store at room temperature away from heat and moisture, out of the sight and reach of children.

Get medical help straight away if

  • Your face, lips or tongue swell, or you find it hard to breathe.
  • You get a severe rash, blistering or peeling skin.
  • A side effect worries you or doesn’t go away: contact your doctor or pharmacist.
