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.

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.

Atropine eye drops will generally be administered for you, but if you are asked to put the drops in yourself, then:

  1. Wash your hands well before you use the drops.

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

  3. Tilt your head back a little and pull the lower lid of your eye out to form a pocket.

  4. Hold the bottle (or single-dose unit) upside down near to your eye. Try not to touch your eye as you do this.

  5. 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.

  6. 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.

  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 Minims® are enough for both eyes.)

  8. Replace the cap (or if you are using the 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 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.

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.

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

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

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

  • 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.

Preguntas frecuentes

What is the main purpose of atropine eye drops?

Atropine eye drops are primarily used to make your pupil larger and relax the muscles in your eye. This makes it easier for eye examinations and vision tests, especially in young children. They are also used in treating anterior uveitis, reducing pain and allowing the inflamed eye to rest and heal.

How long will my vision be blurry after using atropine eye drops?

Atropine will cause blurred vision, which may last for several hours. You should not drive or operate machinery until your vision has returned to normal and you can see clearly again.

Can I wear my contact lenses while using atropine eye drops?

If you normally wear contact lenses, you should not wear them again until your doctor tells you it is safe. 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 dry mouth or other less common side effects?

Less common side effects like dry mouth, flushing, dry skin, constipation, difficulties passing urine, and a fast heartbeat should pass soon. If any of these continue or become troublesome, you should speak with your doctor.

How should I store atropine eye drops once opened?

Once opened, bottles of atropine eye drops only keep for four weeks. After this time, you should throw the bottle away, even if there is solution remaining, to prevent the risk of eye infections. Minims® single-dose units should be discarded immediately after use and never stored or reused.

What should I do if I am using other eye drops at the same time?

If you are using any other eye drops or ointments, you should leave about ten minutes between applying each one. This allows each medication to be absorbed effectively and prevents them from overflowing from your eye, which could reduce their intended effect.
