Ear infection and ofloxacin ear drops: how to use Effexin safely

How ofloxacin ear drops (Effexin 0.3%) are used for ear infections, how to put them in safely, when not to use them, and the warning signs that need a doctor.

CAREPLUS Clinic · 17 October 2026 · 2 min read

Effexin Otic Solution contains ofloxacin 0.3%, an antibiotic used as ear drops for infections of the outer ear, such as swimmer’s ear. See Effexin ear drops at CAREPLUS. A doctor reviews your order before it is sent.

In short: use the drops exactly as the leaflet says, make sure the eardrum is intact, and see a doctor if the ear is not better within a few days.

What the infection usually feels like

Outer ear infections cause ear pain (often worse when you pull the ear or chew), itching, redness, a feeling of fullness and sometimes a smelly discharge. They are common after swimming or when water stays in the ear.

How to use the drops

  • Warm the bottle in your hand for a minute, so the drops are not cold in the ear.
  • Lie with the affected ear facing up, and gently pull the ear back and up (adults) to open the canal.
  • Put in the number of drops stated in the leaflet. Keep the tip clean and do not let it touch the ear.
  • Stay lying down for a few minutes, then wipe away any drops that run out.
  • Wash your hands after use, and keep the bottle closed.

When not to use them

  • if you are allergic to ofloxacin or other quinolone antibiotics
  • if your eardrum has a hole or you have ear tubes, unless a doctor has said it is safe
  • if you have a fungal infection of the ear, unless a doctor has checked it

Side effects

A mild stinging, itching or burning when first used is common. Stop and see a doctor if you get a rash, severe pain, swelling, dizziness, hearing changes, or the ear discharges blood.

See a doctor if

  • you have a fever, or the pain spreads to the face, neck or behind the ear
  • the ear does not start to improve within a few days, or gets worse
  • you have had a recent ear injury or ear surgery

Questions people ask

Can I use ear drops if my eardrum has a hole?

Only if a doctor has said it is safe for you. Medicine can reach the middle ear through a hole in the eardrum, so check with a doctor before using them.

What if the drops sting?

A mild stinging or burning when first used is common. Stop and see a doctor if the pain is severe, you have a rash, or your ear swells.

How do I know the infection is getting better?

Pain, itching and discharge should ease within a few days. If they do not improve, or they get worse, see a doctor.
