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

Dorzolamide 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. Dorzolamide is available as a combination eye drop with a beta-blocker called تيمولول, in a brand called Cosopt®.

Before using dorzolamide

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 ترتدي عدسات لاصقة ناعمة.

• إذا كنت حاملاً أو مرضعة.

• If you have any problems with the way your kidneys work, or if you have ever had kidney stones.

• إذا كان لديك أي مشاكل في كيفية عمل الكبد لديك.

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

• If you have dry eye disease or are using eye drops for dry eyes.

• 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 dorzolamide eye drops

1. اغسل يديك قبل استخدام القطرات.

2. Remove the cap (or the tip of the unit if you are using a single-dose unit).

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

4. أمسك الزجاجة (أو الوحدة ذات الجرعة الواحدة) مقلوبة بالقرب من عينك. حاول ألا تلمس عينك أثناء القيام بذلك.

5. Press the container gently 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. استبدل الغطاء (أو إذا كنت تستخدم الوحدة ذات الجرعة الواحدة، فتخلص منها).

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 used two or three times each day, depending on whether you are also using other drops. Your doctor will tell you how many times a day is right for you and 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 do 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 bottles of eye drops contain preservatives which can affect soft contact lenses. The single-dose units do not contain a preservative.

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

• If you are having an operation or any medical treatment, remember to tell the person carrying out the treatment that you are using dorzolamide eye drops.

Can dorzolamide eye drops cause problems?

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 dorzolamide. 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.

How to store dorzolamide

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

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

• Bottles of eye drops 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 to prevent the risk of eye infections.

• Single-dose units should be used as soon as the unit is opened. Do not store or re-use opened units for subsequent doses. This is because the units do not contain any preservative.
