Brinzolamide
Brinzolamide eye drops lower the pressure inside the eye in glaucoma and ocular hypertension. This page carries Azopt, a 1% suspension in a bottle.
How brinzolamide lowers eye pressure
Brinzolamide is a carbonic anhydrase inhibitor. It blocks an enzyme in the ciliary body, the ring of tissue that produces the clear fluid filling the front of the eye. With the enzyme slowed, less fluid is made and the pressure inside the eye falls. It is used for glaucoma and for ocular hypertension (raised pressure inside the eye without optic nerve damage). High pressure is what harms the optic nerve over time, so the aim is to keep it down every day. The drops hold the pressure steady rather than cure the condition, and they work only while they are used.
Using the drops
The dose is one drop in the affected eye, three times a day, at about the same times each day. The bottle needs a good shake before every use, because the medicine settles when it stands. Keep the dropper off the eye and lashes, and press a finger on the inner corner by the nose for two to three minutes afterwards so less of the drop drains away. Other eye drops are kept ten minutes apart from it, and soft contact lenses wait fifteen minutes. Vision can blur for a little while.
What side effects look like
Stinging or a gritty feeling in the eye, redness, dry eyes and short-lived blurring are the everyday ones. A bitter or sour taste is common too, and it comes from drops draining through the tear duct into the throat. Headache and a runny nose are also reported, and most of these settle as the eye adjusts. A rash — more likely if you are allergic to sulfa drugs — swelling of the eyelids, lips, tongue or skin, itching or discharge from the eye, eye pain, trouble breathing or swallowing, or a sore throat with fever all need urgent treatment.
Azopt 1% eye drops
The brinzolamide product here is Azopt, a 1% eye drop suspension in a bottle. That is the strength brinzolamide eye drops come in. It sits alongside the other glaucoma and dry-eye medicines in Eye Care.
Mixing brinzolamide with other medicines
Brinzolamide is a sulfonamide, the same family as acetazolamide, the tablet carbonic anhydrase inhibitor. Using both adds to the pressure-lowering effect and to the chance of tiredness, tingling in the hands and feet, or passing more urine.

What are the brand names for brinzolamide?
Azopt is a brand name of brinzolamide. Here, brinzolamide can be bought online as generic Azopt. These are generics, not the original brand.
How often should I use brinzolamide eye drops?
Three times a day, at roughly the same times each day, with one drop going into each affected eye. Keeping to a steady pattern matters more than hitting an exact hour — the pressure creeps back up when doses are missed.
Does brinzolamide cure glaucoma?
No. Brinzolamide lowers the pressure inside the eye, which is what protects the optic nerve, but the condition itself remains. That is why the drops go in every day, including on days when the eyes feel perfectly normal.
Can I wear contact lenses while using brinzolamide?
Soft lenses can be worn, but wait at least fifteen minutes after a dose before you put them in. A lens placed sooner can hold the drops against the surface of the eye for longer than intended.
Can I use brinzolamide with other glaucoma drops?
Yes. Brinzolamide is often added as a second drop when one pressure-lowering drop is not enough, with ten minutes between the two bottles.
Is brinzolamide the same as Azopt?
Azopt is the brand name for brinzolamide; the active ingredient is the same substance described on this page. The Azopt bottle sold here holds the 1% suspension, the strength brinzolamide eye drops come in.
