Dorzolamide and Timolol combination belongs to the Antiglaucoma and Beta-adrenergic therapeutic class. This combination is usually available in solution form.
The ophthalmic drops are mainly used to decrease intraocular pressure caused by ocular hypertension or open-angle glaucoma. Prolonged increases in intraocular pressure can cause pain and damage your vision. This is where this medication’s mechanism of action kicks in. It reduces pain and prevents vision loss by alleviating high intraocular pressure.
Dorzolamide and Timolol eye drops are only available with a prescription.
2 What to Know Before Using
Before beginning treatment with this medication, you and your physician need to weigh the risks and benefits of using the dorzolamide and timolol combination. Several considerations are to be noted as well. First, your healthcare team needs to make sure you are not allergic to this medication or any of its components.
Inform them if you have allergies to animals, food preservatives, dyes, and other medications as well.
Studies have found that the effects of Dorzolamide and Timolol ophthalmic drops are not influenced by any age-related factor in pediatric patients although safety and efficacy are yet to be established in children younger than 2 years old.

Use the exact brand that was prescribed since the eye drops vary. Cosopt® PF does not have preservatives, whereas Cosopt® does.
Ask your healthcare professional to demonstrate the proper way of administering the drops. Although the steps for Cosopt® PF and Cosopt® have variations, they generally have the same principles. If you wear contact lenses, take them out before administering the drops.
Also, for cases where your doctor prescribes 2 different types of medications, wait for 5 to 10 minutes before administering the second medication. This prevents the first medication getting washed out. Again, follow your physician’s instructions when it comes to dosage and timing.
Normally for glaucoma, use one drop in the affected eye twice a day, preferably morning and evening.
This is for adults. If you missed a dose, take it immediately. However, if the next schedule is close, skip it and resume the normal timing.
Store your medications in a safe place and away from children’s reach. Discard expired medications.
