How to use Cromolux
If you do not understand the instructions on the box/bottle, ask your doctor or pharmacist for help.
How to use it
Adults and children: 1 – 2 drops into each eye 4 – 6 times a day at regular intervals. Continue with treatment for as long as needed to sustain relief. Using Cromolux for about a week before the expected allergy season may help reduce the symptoms associated with eye allergies.
- Wash your hands well with soap and water.
- Remove the lid from the bottle.
- Hold the bottle upside down between your thumb and index finger.
- Using your other hand, gently pull the lower eyelid down to form a pouch.
- Tilt your head back and look up.
- Put the tip of the bottle close to your lower eye. Do not let it touch your eye.
- Release one drop into the pouch formed between your lower eyelid and your eye by gently squeezing the bottle.
- Close your eye and keep it closed. Do not blink or rub your eye.
- While your eye is still closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can absorbed to other parts of your body. Ask your doctor for more specific instructions on this technique.
- Replace the lid, sealing it tightly.
- Wash your hands again with soap and water to remove any residue.
Wait at least 20 – 30 minutes before replacing your soft contact lenses.
Be careful not to touch the dropper tip against your eye, eyelid or anything else to avoid contaminating the eye drops.
Contaminated eye drops may give you an eye infection.
You may feel a slight burning sensation in the eye shortly after using the eye drops.
If this persists, or is very uncomfortable, contact your doctor or pharmacist.
How long to use it
Continue with treatment for as long as needed to sustain relief.
If you use too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (Australia: telephone 13 11 26, New Zealand: telephone 03 474 7000) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Cromolux. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
