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

Também chamado de

Mydrilate®; Minims® Cyclopentolate Hydrochloride

Disponível 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 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.

  • 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.

  • Se você tem uma condição que causa fraqueza muscular, chamada miastenia gravis.

  • Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

  • Se você está grávida ou amamentando.

Cyclopentolate 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. 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.

  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.

  • 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.

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.

Cyclopentolate side-effects

O que posso fazer se passar por isso?

Eye irritation such as mild stinging

Isso deve passar em breve

Large pupil, blurred vision, difficulty with focusing

These may last for several hours. Do not drive and do not operate machinery until your vision is clear again

Rare side-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

Important: occasionally people can be allergic to eye drops, particularly if the eye drops contain a preservative. If you notice a rash around your eyes, or any swelling or itching, stop using the drops and contact a doctor or pharmacist for advice. Long-term use of preserved eye drops may lead to eye irritation and symptoms of dry eyes. If your eyes or eyelids become red or inflamed after using the drops, contact your doctor for advice.

Se você sentir quaisquer outros sintomas que acha que podem ser causados pelas gotas para os olhos, fale com seu médico ou farmacêutico para mais orientações.

  • Mantenha todos os medicamentos fora do alcance e da vista das crianças.

  • 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.
