Brinzolamide eye drops for glaucoma

About brinzolamide eye drops

An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. Glaucoma can lead to a loss of vision if it is not treated. If you have an increased pressure within your eye but without any damage to the optic nerve, this is called ocular hypertension. People with ocular hypertension have an increased risk of later developing glaucoma. Treatment with eye drops such as brinzolamide helps to reduce eye pressure in people with ocular hypertension, and to prevent further eye damage in people with glaucoma.

Brinzolamide works by blocking the action of an enzyme called carbonic anhydrase. Blocking this enzyme reduces the amount of fluid that you make in the front part of your eye (called aqueous humour), and this helps to lower the pressure within your eye.

Sometimes, more than one type of eye drop is needed to keep the pressure in the eye low. If this is the case for you, you may be asked to use two different eye drops, or you may be given drops which combine more than one type. Brinzolamide is available as a combination eye drop with a beta-blocker called timolol (in a brand called Azarga®), and with a medicine called brimonidine (in a brand called Simbrinza®).

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using the drops it is important that your doctor knows:

• אם את בהריון או מניקה.

• If you have any problems with the way your kidneys work or with the way your liver works.

• If you wear soft contact lenses.

• If you have a condition where your blood acidity is too high, called hyperchloraemic acidosis.

• If you are taking any medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

• If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you have ever had a bad reaction to any other eye drops, or to a type of medicine known as a 'sulfonamide'.

1. שטוף את ידיך היטב לפני השימוש בטיפות.

2. הסר את המכסה.

3. Tilt your head back a little and pull the lower lid of your eye out to form a pocket.

4. החזק את הבקבוק הפוך קרוב לעין שלך. נסה לא לגעת בעין שלך בזמן שאתה עושה זאת.

5. Apply enough pressure to the base of the bottle to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.

6. עצום את עינך לדקה או שתיים, ולחץ בעדינות על הצד של האף שלך שבו הפינה של העין שלך פוגשת את האף. זה עוזר למנוע מהטיפה להתנקז ושומר אותה בעין שלך.

7. חזור על התהליך בעין השנייה אם נאמר לך להשתמש בטיפות בשתי העיניים.

8. החלף את המכסה.

• Before you start using the eye drops, read the manufacturer's printed information leaflet from the pack. It will give you more information about the eye drops and will provide you with a full list of the side-effects which you may experience from using them.

• Use one drop into the eye (or eyes) affected. The drops are usually used two or three times each day, but your doctor will tell you how many times a day is right for you - your dose will also be printed on the label of the pack. Remember to use the drops at regular intervals and try not to miss any doses.

• If you forget to use the drops, put them in as soon as you remember, but do not 'double up' to make up for any missed doses.

• Take care not to touch the tip of the dropper with your eye, fingers, or any other surface. This is to prevent the drops from becoming contaminated.

• If you are using any other eye drops, leave 5-10 minutes between applying each one. This is to prevent more liquid going into your eye than it can handle. Otherwise the drops will overflow from your eye and not have the intended effect.

• When first put in, eye drops can make your eyes water and may sometimes cause blurred vision. If this happens, it should quickly clear. Make sure you can see clearly again before you drive and before you use tools or machines.

• Do not wear soft contact lenses unless your doctor has advised you otherwise. This is because there is a preservative in bottles of eye drops which can affect soft contact lenses.

• Keep your regular appointments with your doctor and eye clinic so that your progress can be checked.

• If you are having an operation or any dental treatment, remember to tell the person carrying out the treatment about any medicines you are taking or using.

Along with their useful effects, eye drops can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with brinzolamide. You will find a full list in the manufacturer's information leaflet supplied with your drops. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

• שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.

• יש לאחסן במקום קריר ויבש, הרחק מחום ואור ישיר.

• Eye drops in bottles only keep for four weeks once the bottle has been opened, so do not use the drops if the bottle has been open for longer than this. This will help reduce the risk of eye infections.
