Bétaxolol collyre pour le glaucome

About betaxolol eye drops

In 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.

Before using betaxolol eye drops

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.

• Si vous êtes enceinte ou si vous allaitez.

• Si vous souffrez d'une maladie cardiaque.

• 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.

• Si vous prenez des médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

• 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.

How to use betaxolol eye drops

1. Lavez-vous bien les mains avant d'utiliser les gouttes.

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

3. Penchez légèrement la tête en arrière et tirez la paupière inférieure de votre œil pour former une poche.

4. Tenez le flacon (ou l'unidose) à l'envers près de votre œil. Essayez de ne pas toucher votre œil.

5. Exercez une pression suffisante pour faire tomber une goutte dans l'œil. N'utilisez une deuxième goutte que si la première n'est pas parvenue à pénétrer dans l'œil.

6. Fermez l'œil pendant une minute ou deux et appuyez doucement sur le côté de votre nez, à l'endroit où le coin de l'œil rejoint le nez. Cela permet d'empêcher la goutte de s'écouler et de la maintenir dans l'œil.

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).

Tirer le meilleur parti de votre traitement

• Avant de commencer à utiliser le collyre, lisez la notice d'information imprimée par le fabricant qui se trouve dans l'emballage. Elle vous donnera plus d'informations sur le collyre et vous fournira une liste complète des effets secondaires que vous pourriez ressentir en l'utilisant.

• 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.

• Veillez à ne pas toucher l'extrémité du compte-gouttes avec votre œil, vos doigts ou toute autre surface. Ceci afin d'éviter que les gouttes ne soient contaminées.

• Si vous utilisez d'autres gouttes pour les yeux, attendez 5 à 10 minutes entre chaque application. Cela permet d'éviter de faire pénétrer dans l'œil une quantité de liquide supérieure à ce qu'il peut supporter. Sinon, les gouttes déborderont de l'œil et n'auront pas l'effet escompté.

• 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.

Can betaxolol 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 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.

Important: si vous présentez les symptômes suivants, demandez immédiatement conseil à votre médecin :

• 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.

Si vous ressentez d'autres symptômes qui pourraient être dus au collyre, demandez conseil à votre médecin ou à votre pharmacien.

How to store betaxolol eye drops

• Conservez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.

• 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.
