What is Timolol Maleate Ophthalmic Solution?

Timolol Maleate Ophthalmic Solution is used to treat open-angle glaucoma and glaucoma caused by another disease of the eye (secondary glaucoma). Timolol Maleate 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 does Timolol Maleate Ophthalmic Solution work?

Timolol Maleate Ophthalmic Solution 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 Maleate Ophthalmic Solution 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.

Timoptic (Merck)

Timolol Maleate Ophthalmic Solution

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Your cat may need to use these medications life long, which is not uncommon. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal.

What is the difference between dorzol / timolol and timolol alone?

Asked by: Anonymous
The DORZOLAMIDE/TIMOLOL combination is used when two medications are needed to reduce pressure in the eye from glaucoma when the one agent one it's own ( example just TIMOLOL ) is not effective

Is this the same as Latanoprost (Xalatan) ophthalmic?

NO! Xalatan is a much more powerful (therefore more expensive.) Timolol SHOULD NOT be used as a replacement!

If my cat normally gets 2 drops of a .25% solution, how many drops would he take of the .5% solution?

Asked by: Anonymous
You should not increase to the 0.5% without speaking to your veterinary ophthalmologist. Timolol can rarely cause heart problems, but in smaller patients such as cats they should be monitored closely.

if my dog gets one drop of timolol one to two times a day of .25% then how many drops of .5% can i give her? can i give them to her?

Asked by: Anonymous
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.

In an abundance of caution I would suggest you contact your veterinarian to advise him/her of what happened. Your veterinarian may or may not want to examine your pet.
