What are antazoline’s uses?

Antazoline (also known as antazoline phosphate) is an antihistamine recommended for the relief of allergic conjunctivitis. It eases redness and itching in the eyes.

What dosage should you take?

Use one drop two or three times a day in both eyes.

What special precautions should you take?

  • It is not recommended for use during pregnancy or during breastfeeding. First consult with your doctor or Clicks pharmacist.
  • If you are pregnant or breastfeeding and do use these eye drops (only on your doctor's advice), you can minimise the amount of medicine that is absorbed into your bloodstream by pressing on your tear duct while putting in the drops, and for a few minutes after.
  • When first put in, eye drops may cause blurred vision. Wait until this clears before you drive.
  • Eye drops only keep for four weeks once the bottle has been opened so throw away the bottle after this time.
  • Take care not to touch your eye, fingers, or any other surface with the dropper of the bottle. This could contaminate the drops left in the bottle.
  • If you are using any other eye drops or ointments, leave about 10 minutes between applying each one.
  • Do not wear soft contact lenses while you are using these eye drops.
  • Not suitable for children under 12 years of age.
  • If you are using more than one type of eye drop you should administer them at least five minutes apart, to prevent the second drop washing away the first.

  • Closed-angle glaucoma (an eye disorder that results in optic nerve damage)
