Quick answer

Antibiotic eye drops are prescribed for bacterial conjunctivitis when a clinician thinks bacteria are the likely cause — for example thick yellow-green discharge and crusty lids on waking. They are not needed for most viral or allergic pink eye. Use only the drops prescribed for you, finish the course unless advised otherwise, and seek urgent care if pain or vision worsens.

## When antibiotics help

Bacterial conjunctivitis often improves with hygiene alone, but antibiotic drops or ointment may speed recovery and reduce spread, especially in children, contact lens wearers, or when discharge is thick. Your clinician decides based on symptoms and local guidance — not every red eye needs antibiotics.

## How to use drops safely

Wash and dry hands. Tilt the head back, pull down the lower lid, and place the drop in the pocket without touching the bottle tip to the eye or lashes. Wipe away excess. If using ointment at night, a brief blur is normal.

- Use only the medicine and schedule prescribed for you
- Discard open bottles after the period advised on the label
- Do not share drops between family members
- Remove contact lenses unless your clinician says to keep wearing them

## When antibiotics are not appropriate

Viral conjunctivitis linked to colds is usually watery and self-limiting — antibiotics do not kill viruses. Allergic conjunctivitis needs allergen avoidance and anti-allergy treatment. Using leftover antibiotic drops without assessment can delay correct care for ulcers or uveitis.

## Side effects and follow-up

Mild stinging is common. Stop and seek advice if you develop a rash, worsening redness with pain, or blurred vision. Return if symptoms do not improve after several days on treatment, as the diagnosis may need review.

## Frequently asked questions

### Can I buy antibiotic eye drops without a prescription?

Rules vary by country. In many places they require a prescription. A pharmacist or clinician can advise what is appropriate for your symptoms.

### How long should I use antibiotic eye drops?

Follow the course your clinician prescribes, often five to seven days. Do not stop early without advice, and do not extend use beyond the prescribed period.

### Are antibiotic eye drops the same as lubricating drops?

No. Lubricating drops moisten the surface and do not treat bacterial infection. Using the wrong product can give false reassurance while an infection continues.

Your next step

## Take this to your appointment

Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
