Michael Stewart 09/05/2018: There are currently no licensed eye drop products containing homatropine available in the UK. Homatropine eye drops may still be available in other countries. This Medicine Leaflet is based on medical information available in the UK at the time of writing and is left here for reference purposes only. Please also refer to the manufacturer's information supplied with your medicine.
Homatropine 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 homatropine eye drops
Tipo de medicamento | An antimuscarinic |
Usado para | To make the pupil of your eye larger and relax the muscles in your eye |
Disponible como | Eye drops (discontinued UK) |
Homatropine 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.
Homatropine 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 homatropine 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 are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
Si estás embarazada o amamantando.
How to use homatropine eye drops
Homatropine 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.
Retire la tapa.
Tilt your head back a little and pull the lower lid of your eye out to form a pocket.
Sostén la botella boca abajo cerca de tu ojo. Intenta no tocar tu ojo mientras haces esto.
Apply enough pressure to the dropper 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.
Repite el proceso en tu otro ojo si te han indicado usar las gotas en ambos ojos.
Obteniendo el máximo de tu tratamiento
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.
Homatropine 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.
Can homatropine 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 homatropine eye 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.
Homatropine side-effects | ¿Qué puedo hacer si experimento esto? |
Eye irritation such as mild stinging | Esto debería pasar pronto |
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 |
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.

Preguntas frecuentes
What is the primary use of homatropine eye drops during an eye examination?
Homatropine eye drops are used to make the pupil of your eye larger and to relax the muscles inside your eye. This process makes it easier for an ophthalmologist to examine your eye thoroughly and test your vision accurately.
How do homatropine eye drops help people with anterior uveitis?
For those with anterior uveitis, homatropine eye drops help by enlarging the pupil and relaxing the eye muscles. This action reduces pain and allows the inflamed parts of the eye to rest and begin to heal.
Are there any specific situations where homatropine eye drops should not be used?
Yes, homatropine eye drops should be used with caution or avoided if you have a history of allergic reactions to other eye drops, or if you have a higher than normal pressure in your eye or glaucoma. It’s important to inform your doctor about these conditions.
Can homatropine eye drops be used while pregnant or breastfeeding?
If you are pregnant or breastfeeding, you should inform your doctor before using homatropine eye drops. Your doctor will need to consider whether it is the right treatment for you in these circumstances.
Why is it important to press gently on the side of my nose after applying the drops?
After applying the drops, closing your eye for a minute or two and pressing gently on the side of your nose (where the corner of your eye meets your nose) helps to prevent the drop from draining away. This ensures the medication stays in your eye to have its intended effect.
What should I do if I am prescribed homatropine eye drops and also use other eye medications?
If you are using other eye drops or ointments, you should wait approximately ten minutes between applying each one. This prevents too much liquid from entering your eye, which could cause the drops to overflow and reduce their effectiveness.
Why can't I keep opened bottles of homatropine eye drops for later use?
Homatropine eye drops do not contain a preservative. To prevent the risk of eye infections, the bottle should be discarded immediately after use and never stored for future application.
