Zaditor is an eye medication used to treat and prevent eye itching caused by a seasonal allergy. The active ingredient in this medication is ketotifen. This is an antihistamine that works to treat symptoms of conjunctivitis caused by allergens. This antihistamine blocks the histamines that the body releases when it’s exposed to an allergen. It’s the histamines that cause allergic reactions.

Histamines are natural chemicals that can cause symptoms like itchy eyes, watery eyes, swelling of the eyes, and redness. Zaditor is a mast cell stabilizer that reduces the amount of histamines released by these cells. This medication is in the form of eye drops applied directly to the eyes. They take just a few minutes to start working. Your doctor or ophthalmologist may recommend taking this medication to reduce the allergic symptoms affecting your eyes. It provides temporary relief and can be taken by people aged three and up.

Zaditor Precautions and Warnings

Once you apply this medication, you might have blurry vision for a little while. This is only a temporary effect. Don’t operate dangerous machinery, such as a vehicle, until the blurriness clears and you can manage it safely. This medication shouldn’t be used by anyone under three years old unless the doctor directs that it should be used for the child. If a child uses it, don’t allow them to apply it alone. They could accidentally apply far too much of this medication.

If you’re pregnant, only take this medication when it’s needed. It’s unclear how it can affect the unborn. It’s also unknown whether Zaditor is found in breast milk. Talk to your doctor before using it while breastfeeding.

Don’t use this medication if you have eye irritation from causes other than allergies, such as from wearing your contact lenses. It won’t help with eye irritation from contacts, eye injuries, or other problems. If you wear contact lenses, don’t apply this medication while they’re in. Remove them and then use the medication. After that, wait at least 10 minutes before you put the contacts back in.

Side Effects Of Zaditor

If you have these symptoms, you can talk to your doctor about whether or not to continue using it. If you have these symptoms and they get worse, it’s usually best to stop taking the medication.

There are also severe side effects possible. These can include eye pain, eye swelling, and developing vision problems. It’s possible to get a discharge from the eyes or to have changes in your eyelids. If you have these side effects, your doctor must know immediately.

Like other medications, it’s possible to have side effects from using Zaditor. When you use it, it’s possible to have these symptoms:

  • Stinging in the eye
  • Burning eyes
  • Eye irritation
  • Runny nose
  • Stuffy nose
  • Headaches
  • Tasting a lousy taste
  • Dry eyes
  • Red eyes

Allergic Reactions to Zaditor

If you have an allergy to ketotifen or any of this medication’s inactive ingredients, don’t take Zaditor. If you aren’t sure about the inactive ingredients, talk to the pharmacist or take the package to your doctor and ask whether you have a problem with any of the ingredients. Before you take it, it’s best to get a recommendation for it from your doctor. Make sure your doctor knows about all your health conditions and all the medications that you’re taking. If you have any eye problems like glaucoma, make sure the doctor knows this before recommending that you take this medication.

It’s also possible to have an allergic reaction to this medication, though it’s rare. If you have swelling of your throat, face, or tongue, you may be having a severe reaction to this medication. If you have itching, a rash, trouble breathing, or severe dizziness, stop taking the medication and get medical assistance immediately.

Drug Interactions of Zaditor

If there is a drug interaction between Zaditor and other medications that you are taking, it could change the way the medicines work. It could also put you at a higher risk of severe side effects. When you take a medication that is applied to the eyes, it generally doesn’t have as many possible drug interactions as many other types of medications. However, that doesn’t mean that there can’t be any interactions.

In general, you shouldn’t take another medication meant for the eyes (such as Pazeo or FML Eye Drops) at the same time as you take Zaditor unless directed to by your doctor. If your doctor recommends taking Zaditor, make sure they know about the other medications you take in case of an interaction. If you take something else that could interact poorly with Zaditor, don’t stop taking the other medication unless your doctor agrees.

If you are taking other medications for allergies, ensure your doctor knows about them. You may also want to talk to your pharmacist about whether another allergy medication can be taken with this one. Also, let your doctor or pharmacist know if you use caffeine, alcohol, nicotine, cannabis, etc., as well as any OTC medications or supplements. Any of these may interact with the medication and cause worse side effects or other problems.

How To Use Zaditor

When you’re ready to take this medication, make sure you read all of the instructions.

  1. Wash your hands thoroughly. Please don’t touch the end of the dropper or allow it to touch anything else.
  2. Tilt your head backward and look up.
  3. Pull down your bottom eyelid.
  4. Drop one drop into each eye into the space left by the lower eyelid. If your doctor recommends a different dosage, apply that many drops.
  5. Close your eyes for a minute or two.

Zaditor Strengths and Dosages

The standard dosage is one drop added to each eye twice a day. Generally, you’ll need to keep about eight to 12 hours between each dose. If your doctor recommends a different dosage, follow their recommendation. Other bottle sizes have different amounts of the medication in them. This medication is over the counter, so there are various sizes, including bottles that hold 5 mL and those that have 10 mL. Many of the packages are 12-hour formulations.

If a doctor directs you to take another eye medication along with this one, wait at least five minutes before you add the second one. Ensure you do not wear your contacts when placing drops in your eyes. This medication has a preservative that can stain contacts. If you see that the Zaditor drops have particles in them or have changed color, don’t take them. Store the bottle at room temperature. Never freeze this medication.
