Chloramphenicol Eye Drops: What They Are and When to Use Them

Chloramphenicol eye drops are a type of antibiotic made for eye infections. They fight the bacteria that cause redness, swelling, and discharge. Doctors often prescribe them for conjunctivitis, corneal ulcers, and other bacterial eye problems. If you’ve been told to use them, it’s because a bacterial infection is likely the cause of your symptoms.

How to Use Chloramphenicol Eye Drops Correctly

First, wash your hands. Tilt your head back and pull the lower eyelid down gently to make a small pocket. Hold the bottle above the eye without touching it and squeeze out the recommended number of drops—usually one or two per eye.

Close your eye for about a minute and press lightly on the inner corner of the eye with a finger. This helps keep the medicine from draining into the tear duct too quickly. If you need to use more than one type of eye drop, wait at least five minutes before applying the next one.

Typical dosing is one to four times a day, based on what your doctor says. Never double up if you miss a dose; just take the next one at the regular time. Keep the bottle capped tightly and store it at room temperature away from direct heat.

Possible Side Effects & Precautions

Most people tolerate chloramphenicol eye drops well, but a few may notice mild irritation, a temporary blurry vision, or a slight burning feeling after the drop. If you see a rash, swelling around the eye, or intense pain, stop using the drops and call a doctor right away—these could be signs of an allergic reaction.

Because chloramphenicol can affect blood cells in rare cases, doctors avoid prescribing it for long periods unless absolutely necessary. If you have a history of blood disorders or are pregnant, tell your doctor before starting treatment.

Do not share the bottle with anyone else, even if they have similar symptoms. A shared bottle can spread germs and also give the wrong dosage to another person.

When you finish the prescribed course, do not keep using the drops just because your eyes feel better. Stopping early can let the infection come back or become resistant to the medicine.

In short, chloramphenicol eye drops are a reliable option for bacterial eye infections when used exactly as prescribed. Follow the dosing schedule, watch for any unusual reactions, and store the medication properly. If anything feels off, reach out to your healthcare provider to stay safe and get your eyes back to normal.
