Brimonidine eye drops for glaucoma

About brimonidine 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 brimonidine eye drops helps to reduce eye pressure in people with ocular hypertension, and to prevent further eye damage in people with glaucoma.

Brimonidine eye drops are thought to work by reducing the amount of fluid that you make in the front part of your eye (called aqueous humour) and by increasing the drainage of fluid from your eye. These two actions help 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. Brimonidine is available as a combination eye drop with تيمولول (حاصر بيتا) in a brand called Combigan®, and with brinzolamide (a carbonic anhydrase inhibitor) in a brand called Simbrinza®.

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

• إذا كنت ترتدي عدسات لاصقة ناعمة.

• إذا كنت حاملاً أو مرضعة.

• If you have a heart condition or blood vessel disorder.

• If you have a blood circulation problem (particularly if you have Raynaud's syndrome).

• If you feel dizzy when you sit up or stand up quickly.

• If you have a depressive illness.

• إذا كان لديك أي مشاكل في طريقة عمل الكبد لديك، أو أي مشاكل في طريقة عمل الكلى لديك.

• إذا كنت تتناول أو تستخدم أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

1. اغسل يديك جيدًا قبل استخدام القطرات.

2. قم بإزالة الغطاء.

3. أمل رأسك قليلاً للخلف واسحب الجفن السفلي لعينك للأسفل لتشكيل جيب.

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

5. Apply enough pressure to the bottle to release one drop into your eye. (Do not use more than one drop - using several drops does not improve your glaucoma but will increase the risk of side-effects.)

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.

• 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 used twice each day, 12 hours apart. Your dose will also be printed on the label of the bottle to remind you.

• Remember to use the drops at regular intervals and try not to miss any doses. If you do forget, use them as soon as you remember (unless it is nearly time for your next dose, in which case just use the drops when they are next due). Do not 'double up' to make up for a missed dose.

• 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.

• 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, or use tools or machines.

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

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

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 brimonidine. You will find a full list in the manufacturer's information leaflet supplied with the drops. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist for further advice if any of the following continue or become troublesome.

• Eye drops can be used for four weeks once the bottle has been opened. Even if there is still some solution remaining after this time, throw it away and use a new bottle. This will help to prevent the risk of eye infections.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

• احفظه في مكان بارد وجاف، بعيدًا عن الحرارة المباشرة والضوء.
