Xylase-T eyedrop is used for the treatment of increased intraocular pressure (pressure inside the eye). Xylase-T is a drug combination containing two active substances: latanoprost (a prostaglandin derivative) and timolol maleate (a beta-blocker). Fluid known as aqueous humour is produced inside the eye. This fluid is then drained back into the blood stream, thereby maintaining the required pressure within the eye increase. 

Xylase-T is used to reduce inner eye pressure in patients with open-angle glaucoma (damage to the optic nerve, caused by excessive pressure within the eye) and in patients  for whom the effect of beta-blockers or prostaglandin derivatives alone is not sufficient. 

  • If you are allergic to latanoprost or timolol, beta-blockers or any of the other ingredients of Xylase-T. 
  • If you have now or have had in past respiratory problems such as asthma, severe chronic obstructive bronchitis (severe lung disease which may cause wheeziness,  difficulty in breathing and/or long-standing cough) 
  • If you have serious heart problems or heart rhythm disorders 
  • If you are pregnant (or trying to become pregnant) 
  • If you are breast-feeding.
