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 الجلوكوما. 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 تيمولول (in a brand called Azarga®), and with a medicine called brimonidine (in a brand called Simbrinza®).

Before using brinzolamide eye drops

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:

• إذا كنت حاملاً أو مرضعة.

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

• إذا كنت ترتدي عدسات لاصقة ناعمة.

• 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'.

How to use brinzolamide eye drops

1. اغسل يديك جيدًا قبل استخدام القطرات.

2. قم بإزالة الغطاء.

3. أمل رأسك قليلاً للخلف واسحب الجفن السفلي لعينيك للخارج لتشكيل جيب.

4. أمسك الزجاجة مقلوبة بالقرب من عينك. حاول ألا تلمس عينك أثناء القيام بذلك.

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. أغلق عينك لمدة دقيقة أو دقيقتين، واضغط بلطف على جانب أنفك حيث يلتقي زاوية عينك بأنفك. هذا يساعد على منع القطرة من التصريف ويبقيها في عينك.

7. كرر العملية في عينك الأخرى إذا طُلب منك استخدام القطرات في كلتا العينين.

8. أعد وضع الغطاء.

تحقيق أقصى استفادة من علاجك

• 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.

• إذا كنت تستخدم أي قطرات عين أخرى، اترك 5-10 دقائق بين تطبيق كل واحدة منها. هذا لمنع دخول كمية أكبر من السائل إلى عينك مما يمكنها تحمله. وإلا فإن القطرات ستفيض من عينك ولن تحقق التأثير المطلوب.

• عند وضع قطرات العين لأول مرة، قد تتسبب في دموع العين وقد تسبب أحيانًا رؤية ضبابية. إذا حدث ذلك، يجب أن يتلاشى بسرعة. تأكد من أنك تستطيع الرؤية بوضوح مرة أخرى قبل القيادة وقبل استخدام الأدوات أو الآلات.

• 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.

• حافظ على مواعيدك المنتظمة مع طبيبك وعيادة العيون حتى يمكن متابعة تقدم حالتك.

• 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.
