What is Timolol Ophthalmic Solution?

Timolol ophthalmic is used to treat open-angle glaucoma and glaucoma caused by another disease of the eye (secondary glaucoma). Timolol Ophthalmic Solution requires a prescription from your veterinarian.
For: Dogs

 

Benefits:
Relieves pressure in your pet’s eye
Dropper bottle for ease of administration

How it works:
Timolol is a beta-blocker which acts on receptors in the blood vessels in the eye causing them to constrict. This reduces the amount of fluid (aqueous humor) that passes out of the blood vessels into the eyeball. Timolol also blocks the area of the eye that actively produces aqueous humor.

Cautions:
The dropper opening is sterile, so don’t touch it to any surface, including eyes or hands. If it becomes contaminated, it may cause an infection in the eye.


More Information:
Brand Name
Timoptic (Merck)
Generic Name
Timolol ophthalmic

If it becomes contaminated, it could cause an infection in the eye. Do not use any other eye medication on your pet unless the veterinarian has to told you to do so.

molly has been doing great on this medication . She had an eye removed last April because of glaucoma. this medication is saving her other eye. 08/13/2013
Great Product My husband and I have a Cocker Spaniel that was diagnosed with Glaucoma a few years ago. The vet put him on these drops, once per day in each eye. Since we've been using these drops, my dog has not had any issues in his eyes. He knows that he gets treats when he lets me do his drops, so I don't have to fight with him every day. I think this is a great product! 07/24/2013
Good Product / Shipping not great My dog Lilly has been using this product for several years due to her cataracts causing swelling. It works good but often I have to put drops in 3 to 4 times a day which can get difficult during the work week. However, these drops are cheaper than the alternative so overall I am satisfied. 03/15/2010
Our Bichon-poodle developed cataracts at the age of two. One eye was operated on; the cataract in the other eye had already resorbed and the eye has since been removed. Babs is now six and the vet specialist has prescribed 1 drop of Timolol three times a day to keep the pressure down. It seems to be working, and she is having no problems. However, after reading the other review about a dog receiving only one drop a day I wonder whether our Babs is "over-medicated". I will ask that question of the vet during the next check-up. 02/22/2010
Works great for Maggie After Maggie's surgery for cataracts 1 and 1/2 years ago, her surgeon has gradually reduced the use of Timolol to 1 drop in each eye every night. Within 1 month she had gone almost blind from diabetes and cataracts. She is now almost 11 and doing beautifully. 11/01/2009

Answer: 
Give it twice a day still as prescribed. Timolol is relatively weak in comparison to most glaucoma medications, so you will do no harm by continuing on a twice daily schedule.
