Cyclopentolate eye drops allow your doctor to examine your eye more easily.
The drops can cause blurred vision which may last for several hours. Do not drive and do not use tools or machines until your vision is clear again.
About cyclopentolate 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 | Mydrilate®; Minims® Cyclopentolate Hydrochloride |
Disponible como | Bottles of eye drops and single-dose units (Minims®) |
Cyclopentolate 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.
Cyclopentolate drops can also be prescribed during the treatment of a condition called uveítis anterior. 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 cyclopentolate 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.
If you have any problems with the way your heart works, such as a fast heart beat or heart failure.
If you have epilepsy or you have certain problems with the way your nervous system works, such as ataxia or dementia.
If you have an obstruction in your gastrointestinal tract or urinary tract.
Si tienes una condición que causa debilidad muscular, llamada miastenia gravis.
Si está tomando o usando cualquier otro medicamento. 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 cyclopentolate eye drops
Cyclopentolate 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.
Close your eye for a minute or two and press gently on the side of your nose where the corner of your eye meets your nose. This helps to stop the drop from draining away and keeps it in your eye.
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.
Cyclopentolate 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 cyclopentolate 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 cyclopentolate 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 cyclopentolate 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: Ocasionalmente, las personas pueden ser alérgicas a las gotas para los ojos, especialmente si las gotas contienen un conservante. Si nota una erupción alrededor de los ojos, o cualquier hinchazón o picazón, deje de usar las gotas y contacte a un médico o farmacéutico para obtener asesoramiento. El uso prolongado de gotas para los ojos con conservantes puede provocar irritación ocular y síntomas de ojos secos. Si sus ojos o párpados se enrojecen o inflaman después de usar las gotas, contacte a su médico para obtener asesoramiento.
Si experimenta otros síntomas que cree que pueden deberse a las gotas para los ojos, hable con su médico o farmacéutico para obtener más consejos.
How to store cyclopentolate eye drops
Mantenga todos los medicamentos fuera del alcance y la vista de los niños.
Some brands of cyclopentolate eye drops should be stored in a fridge; others should be stored in a cool, dry place, away from direct heat and light. Please check the label of the preparation you have been given for details.
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 cyclopentolate only. Do not store or re-use opened units to use at a later time.

Preguntas frecuentes
What is the primary difference between Cyclopentolate eye drops and Minims® Cyclopentolate Hydrochloride?
Minims® Cyclopentolate Hydrochloride refers to the single-dose units of the eye drops. These are designed for one-time use, with the contents of one unit being sufficient for both eyes. Cyclopentolate eye drops, on the other hand, can also come in multi-dose bottles.
How long do the effects of Cyclopentolate eye drops typically last, especially regarding blurred vision?
The effects of Cyclopentolate, such as a large pupil, blurred vision, and difficulty focusing, may last for several hours. It is important to ensure your vision is clear again before engaging in activities like driving or operating machinery.
Are there any specific instructions for storing Cyclopentolate eye drops once opened?
Eye drops in bottles only remain usable for four weeks after opening. After this period, the bottle should be discarded, even if there is liquid remaining, to prevent the risk of eye infections. Single-dose Minims® units should never be stored or re-used once opened.
Why is it important to press gently on the side of my nose after applying the eye drops?
Pressing gently on the side of your nose where the corner of your eye meets it helps to prevent the eye drop from draining away too quickly. This ensures that the medicine stays in your eye, allowing it to have its intended effect.
Can I use Cyclopentolate eye drops if I am currently taking other oral medications?
If you are taking or using any other medicines, including those available without a prescription, or herbal and complementary medicines, it's important to inform your doctor. This allows them to ensure the eye drops are safe to use in combination with your current medications.
