Timolol is a beta-blocker that decreases pressure in the eye. It is used in the eye for treatment of glaucoma. It may be used in an unaffected eye to prevent glaucoma when glaucoma is already present in the other eye.
Dose and Administration
Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian.
If discharge is present, the area should be cleansed with a sterile eyewash solution prior to applying the ointment or solution.
Never touch the tip of the tube or dropper to the pet?s eye, lids, or eyelashes. Do not touch the inside of the cap, the dropper, or tube tip with your fingers, as this will also contaminate the medication.
Always wash your hands before and after applying this medication.
If you are applying more than one medication to the eye, allow 5 minutes between applications so one medication is not washed out by the next. Be sure not to interchange the caps of the medications.
If you miss a dose, give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give 2 doses at once.
This medication should only be given to the pet for whom it was prescribed.
