Betaxolol eye drops for glaucoma

About betaxolol eye drops

في chronic open-angle glaucoma there is damage to the optic nerve at the back of your eye. It is usually caused by an increase in pressure within your eye. Betaxolol eye drops work by lowering the pressure in your eye. It is thought they do this by reducing the amount of fluid that you make that fills the front part of your eye (called aqueous humour). By reducing the amount of fluid produced, it reduces the pressure within your eye.

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 drops it is important that your doctor knows:

• If you have asthma or any other breathing problems.

• إذا كنت حاملاً أو مرضعة.

• إذا كنت تعاني من حالة قلبية.

• If you know you have a problem with the surface of your eye (the cornea), or if you have particularly dry eyes.

• If you have circulation problems or low blood pressure.

• If you are being treated for thyroid problems or diabetes.

• If you have a skin condition called psoriasis, or if you have a condition causing muscle weakness, called myasthenia gravis. The symptoms in these conditions could worsen.

• 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 any allergies. It is particularly important that you tell your doctor if you have had a bad reaction to any eye drops.

1. اغسل يديك جيدًا قبل استخدام القطرات.

2. Remove the cap (or twist off 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. اضغط بشكل كافٍ لإطلاق قطرة واحدة في عينك. استخدم قطرة ثانية فقط إذا لم تصل القطرة الأولى إلى عينك.

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. Repeat the process in your other eye if you have been told to use the drops in both eyes. The contents of one single-dose unit are enough for both eyes.

8. Replace the cap (or if you are using a single-dose unit, throw it away).

• 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, twice a day. Remember to use the drops regularly - 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.

• 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 before you use tools or machines.

• Do not wear soft contact lenses if you are using eye drops from a bottle unless your doctor has advised that you can do so. This is because there is a preservative in bottles of eye drops which can affect some soft contact lenses. You may wear soft contact lenses if you are using the single-dose units, as there is no preservative in these drops (but remember to take out your lenses to apply the drops and wait for at least 15 minutes before putting your lenses back in).

• Keep your regular appointments with your 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 that you are using betaxolol eye drops. This is because the drops may interfere with some medicines used during surgery.

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 betaxolol. The best place to find a full list of the side-effects which can be associated with the drops, is from the manufacturer's printed information leaflet supplied with the drops. Alternatively, you can find an example of a manufacturer's information leaflet in the reference section below. Speak with your doctor or pharmacist if any of the following continue or become troublesome.

مهم: if you experience the following, contact your doctor for advice straightaway:

• Any difficulties breathing, such as wheezing or feeling short of breath.

• An allergic-type reaction, such as any swelling around your face or eyes.

Bottles of eye drops contain preservatives which some people can develop an allergic reaction to. If your eye becomes red or inflamed after using the drops, contact your doctor for advice.

إذا شعرت بأي أعراض أخرى تعتقد أنها قد تكون بسبب قطرات العين، تحدث مع طبيبك أو الصيدلي للحصول على مزيد من النصائح.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

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

• Always check the expiry information on the container. Eye drops in bottles 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 immediately the unit is opened. Do not store or re-use opened units for later doses. This is because the units do not contain any preservative.
