Side effects of carmellose sodium eye drops

The most common side effects of carmellose sodium eye drops are burning, itching and stinging of the eyes. These side effects happen in more than 1 in 100 people. They're usually mild and only last for a few minutes after using the drops.

If these side effects continue, you may be sensitive to an ingredient in the eye drops. This could be a preservative, which is something in the eye drops that keeps them clean (sterile) and makes them last longer.

Speak to your doctor, pharmacist or optometrist. They may recommend using a brand that does not contain a preservative, or using single dose (or unit dose) drops or other eye drops for dry eyes.
