About atropine eye drops
Tipo de medicamento | An antimuscarinic |
Usado para | To make the pupil of your eye larger and relax the muscles in your eye |
También llamado | Minims® Atropine Sulphate |
Disponible como | Bottles of eye drops and single-dose units (Minims®) |
Atropine makes the pupil of your eye larger and relaxes the muscles in your eye. These things make it easier for your eye to be examined and your vision tested. It is commonly prescribed for young children who need eye tests.
Atropine drops can also be prescribed during the treatment of a condition called anterior uveitis. This is a painful eye condition caused by inflammation within the eye. By making your pupil larger and relaxing the muscles in your eye, it reduces pain and allows the inflamed part of your eye to rest and recover.
Before using atropine eye drops
To make sure this is the right treatment for you, before you use the drops it is important that your doctor knows:
If you have ever had an allergic reaction to any eye drops.
If you normally wear contact lenses.
If you have been told you have a higher than normal pressure in your eye, or if you have glaucoma.
Si está tomando o usando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
Si estás embarazada o amamantando.
How to use atropine eye drops
Atropine eye drops will generally be administered for you, but if you are asked to put the drops in yourself, then:
Lávese bien las manos antes de usar las gotas.
Remove the cap (or twist off the tip of the unit if you are using a Minims® single-dose unit).
Tilt your head back a little and pull the lower lid of your eye out to form a pocket.
Hold the bottle (or single-dose unit) upside down near to your eye. Try not to touch your eye as you do this.
Apply enough pressure to the container to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.
Cierra el ojo durante uno o dos minutos y presiona suavemente el lado de tu nariz donde la esquina de tu ojo se encuentra con tu nariz. Esto ayuda a evitar que la gota se drene y la mantiene en tu ojo.
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 Minims® are enough for both eyes.)
Replace the cap (or if you are using the single-dose unit, throw it away).
Obteniendo el máximo de tu tratamiento
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 drops and will provide you with a full list of the side-effects which you may experience from using them.
Take care not to touch your eye, fingers, or any other surface with the dropper of the bottle. This could infect the liquid left in the bottle.
Atropine will cause blurred vision which may last for some time. Make sure you can see clearly again before you drive and before you use tools or machines.
If you are using any other eye drops or ointments, leave about ten minutes between applying each one. This is to prevent more liquid going into your eye than it can handle. Otherwise the drops will overflow from your eye and may not have the intended effect.
If you normally wear contact lenses, do not wear them again until your doctor advises you do so. There are two reasons for this - using atropine will mean you are not able to see clearly, and also bottles of eye drops contain a preservative which can affect soft contact lenses.
Can atropine 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 atropine eye drops. You will find a full list in the manufacturer's information leaflet supplied with your drops. Unwanted effects often improve as your body adjusts to a new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Less common effects: dry mouth, flushing, dry skin, constipation, difficulties passing urine, and a fast heartbeat | These should soon pass, but if you become concerned about any, speak with your doctor |
Importante: if you experience the following, contact your doctor for advice straightaway:
Any difficulties breathing, such as wheezing or shortness of breath.

How to store atropine eye drops
Mantenga todos los medicamentos fuera del alcance y la vista de los niños.
Almacenar en un lugar fresco y seco, lejos del calor y la luz directos.
Eye drops only keep for four weeks once the bottle has been opened so throw away the bottle after this time, even if there is some solution left. Never keep opened bottles of eye drops to use later. This will help to prevent the risk of eye infections.
Minims® contain one dose of atropine only. Do not store or re-use opened units to use at a later time.

Preguntas frecuentes
How does atropine specifically help with anterior uveitis?
Atropine helps anterior uveitis, which is a painful eye condition caused by inflammation, by making your pupil larger and relaxing the muscles inside your eye. This combination reduces pain and allows the inflamed part of your eye to rest and recover more effectively.
Are there any specific concerns if I have high eye pressure or glaucoma and need to use atropine eye drops?
Yes, it is important that your doctor knows if you have been told you have a higher than normal pressure in your eye, or if you have glaucoma, before you use atropine eye drops. This information is crucial for them to determine if it is the right treatment for you.
How long do the effects of atropine eye drops typically last, especially the blurred vision?
Atropine will cause blurred vision, and this effect may last for some time. You should make sure your vision is completely clear again before you drive or operate any tools or machines to ensure your safety.
What should I do if I accidentally get more than one drop of atropine in my eye?
The instructions advise applying enough pressure for one drop. You should only use a second drop if the first one missed your eye. The article does not specify what to do if you accidentally administer more than one effective drop, but it does say 'Never use more than the recommended dose'.
What should I do with my contact lenses if I'm prescribed atropine eye drops?
If you normally wear contact lenses, you should not wear them again until your doctor advises you to. This is because atropine will blur your vision, and the preservative in the eye drops can affect soft contact lenses.
What should I do if I experience an allergic reaction to atropine eye drops?
If you experience any difficulties breathing, such as wheezing or shortness of breath, or an allergic-type reaction like swelling around your face, you should contact your doctor for advice straightaway.
Can I use atropine eye drops if I'm pregnant or breastfeeding?
Before using atropine eye drops, it is important to inform your doctor if you are pregnant or breastfeeding. This allows them to assess whether the treatment is suitable for you.
