Nedocromil (Ophthalmic)

Itchy eyes which develop as a result of exposure to an allergen are the primary target of ophthalmic nedocromil, an anti-allergen which is successful in managing this condition.


Ophthalmic nedocromil works to relieve eye itchiness due to allergies by causing a reduction in those substances of the body which trigger an allergic reaction to some stimulus. This medication is delivered via eyedropper, and before it is administered, the patient should thoroughly wash their hands to prepare. Then it is necessary to take care not to touch the tip of the dropper itself so that no contamination reaches the actual eyedropper. The dropper should also not be allowed to touch the eye itself during treatment, nor should it come into direct contact with any other surface.

A standard approach for someone who experiences severe eye itchiness is to take a drop in each eye, twice a day, about 12 hours apart. Your doctor may want to modify this schedule to accommodate any special circumstances or medical conditions which you have, but this is a good starting point. It will generally be necessary to apply these drops in both eyes every day until the allergy season passes, or until you are no longer in a position of exposure to the allergens.

If you wear contact lenses, these should be taken off prior to self-administration, and they should not be worn for about 30 minutes afterwards, because there is a potential for the lenses to absorb the medicine in the eye drops, thereby reducing the applied dosage, as well as its effectiveness.

Side Effects

In addition to the beneficial effects imparted by ophthalmic nedocromil, there may be some undesirable side effects experienced by any patient using the medication. These side effects can be experienced to a very mild degree, a fairly severe degree, or in many cases not at all. If you should experience side effects from taking this medication and it causes you to be more than a little uncomfortable, you should contact your doctor as soon as possible and relate to him/her whatever it is you are experiencing, and how severe you consider the reaction to be.

Although it is rare, some patients who take this medication do experience an allergic reaction to it, and at its absolute worst, this can be extremely dangerous because of the kind of symptoms it produces.

A typical adult dosage for treatment of allergic conjunctivitis would be to administer one or two drops in each eye, twice daily, at intervals approximately 12 hours apart. This routine should be followed for the entire duration of the allergy season, unless for some reason you are no longer exposed to the allergens.

When treating pediatric patients for allergic conjunctivitis, one or two drops should be installed in each eye twice per day, at intervals approximately 12 hours apart. As in the case of adult treatment, this routine should be maintained for the entire duration of an allergy season, or until such time as exposure to allergens is terminated for whatever reason. It is not advised to treat pediatric patients under the age of three years old, unless a doctor has been consulted and has consented to treatment.

It's important to observe good hygiene practices during the process of self-administration of ophthalmic nedocromil, because it is necessary to ensure that no harmful bacteria or germs come in contact with the eye. This means that prior to self-administration, you should wash your hands thoroughly with soap and water, and that you should take precautions that the eyedropper does not come into contact with any surfaces at all during treatment. If you think that the eyedropper has been contaminated in any way, it should be dipped in alcohol to sterilize it once again for the next treatment.

If you should miss a regularly scheduled dosage of this medication, it's better to wait until the next scheduled dosage, rather than to try to get back on schedule by doubling up dosages. Do not share this medication with anyone you know, even if they are suffering from the same exact symptoms that you are.


There are no known interactions between ophthalmic nedocromil and other medications, in large part due to the fact that this is a medicine which is dropped directly into the eyes, and is not ingested so that it reaches the bloodstream. However, it is still advisable for you to make your doctor aware of any other medications which you are concurrently taking so that he/she can make a determination about any adjustments which might be necessary in dosage.

Your list should include all over-the-counter drugs, vitamins, herbal supplements, and other prescription medications you are currently taking, as well as the dosages for each one of these. If necessary, this list can also be taken along when you need to visit an emergency room for treatment, to ensure that a doctor there can be treating your emergency condition without fear of drug interactions.


One of the main precautions to be aware of when taking this medication is that for a period of time after the medicine has reached your eyes, it will cause your vision to be blurry, or a little unstable while the medicine works. For this reason, it is inadvisable to operate a motor vehicle or any other kind of machinery until your vision stabilizes and things become clear again.

Animal studies have turned up no harmful effects to fetuses whose mothers have been treated with ophthalmic nedocromil, and there are likewise no controlled studies in human subjects. Although no adverse effects have been documented, you should still consult with your doctor if you are pregnant or thinking of becoming pregnant, while also being treated with this medication.

It is known that this medicine is passed on to nursing infants through breastfeeding, so this is a decision which should be reviewed with your doctor to consider the pros and cons of breastfeeding. It is expected that only minor amounts of this medicine are passed on in breast milk, but it is still uncertain whether any adverse effects are passed along with it.


This medicine should be stored at room temperature, safely away from extremes of heat, cold, and moisture, and it should never be frozen. The package or container that it comes in should be tightly capped when it is not being used, and the bottle should be stored in a location where pets and curious children cannot gain access.

If a child should accidentally ingest this medication, there should not be any serious danger, because the medicine itself is not poisonous. Still, it's best to take all precautions, since it would be possible for a curious child to access other fluids as well, and these could be dangerous. When the allergy season has passed, and this medication is no longer being used, make sure to dispose of any unused portion of it according to protocols or guidelines given by your doctor or pharmacist.


Ophthalmic nedocromil is a medicine which is used it to combat the symptoms that arise when a patient is exposed to some type of allergen, typically during a season when high concentrations of pollen are aloft in the air. One of the most common allergic reactions to these allergens is a severe itchiness and watering of the eyes, and that is the particular treatment specialty of this medicine.

It is administered either by a doctor in an office or through self-administration at home, via an eyedropper which measures out a precise dosage, and can be efficiently delivered to each eye twice each day, at an interval about 12 hours apart. This medicine is generally effective in the treatment of itchy eyes, but if it fails to relieve your own symptoms, you should alert your doctor to this fact, so that some alternative treatment approach can be considered.
