Product introduction

Zaditen Eye Drop is for external use only. Follow the instructions given by your doctor and use this medicine regularly to get the most benefit. You should gently squeeze the dropper and place the medicine inside the lower eyelid and wipe off extra liquid.  Always wash your hands and do not touch the end of the dropper. This could infect your eye. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back.  Never use a bottle if the seal is broken before you use it for the first time.

The most common side effects of this medicine include eye irritation, eye pain, and punctate keratitis. These are usually temporary and resolve with time. Do not drive, use machinery, or do any activity that requires clear vision until you are sure you can do it safely. Consult your doctor if your condition does not improve or if the side effects bother you.

Do not use this medicine, if you have an eye problem (glaucoma) and untreated eye infection. Your doctor should also know about all other medicines you are taking as many of these may make this medicine less effective or change the way it works.

How to use Zaditen Eye Drop

This medicine is for external use only. Use it in the dose and duration as advised by your doctor. Check the label for directions before use. Hold the dropper close to the eye without touching it. Gently squeeze the dropper and place the medicine inside the lower eyelid. Wipe off the extra liquid.

How Zaditen Eye Drop works

Zaditen Eye Drop is an antihistamine for the eye that treats allergic symptoms by blocking a certain natural substance (histamine). It is also a mast cell stabilizer that prevents allergic reactions by reducing the release of natural substances that cause an allergic reaction. This relieves eye swelling, discomfort, itching and irritation.

Quick tips

  • Gently pull down your lower eyelid and apply only the prescribed Zaditen Eye Drop dose.
  • Do not let the medicine tip touch your eye or anything else to avoid contamination.
  • Wait at least 5 to 10 minutes before using any other eye drops, if prescribed.
  • Avoid wearing contact lenses during treatment unless your doctor clearly says it is safe.
