Driving and using machines


Timoptol contains a substance called timolol which belongs to a group of medicines called betablockers. Timolol lowers the pressure in your eye(s). It is used to treat glaucoma, when the pressure in
the eye is raised.

Do not use Timoptol if:


There are possible side effects associated with Timoptol, such as dizziness, tiredness and changes in
your eyesight, such as blurred vision, drooping of the upper eyelid (making the eye stay half closed),
double vision which may affect your ability to drive and/or operate machinery. Do not drive and/or
operate machinery until you feel well and your vision is clear.


Always use Timoptol exactly as your doctor has told you. You should check with your doctor or
pharmacist if you are not sure. The doctor will decide how many drops you should take each day and
how long you should use them.

The usual dose is one drop in the affected eye(s) twice each day:

one in the morning

one in the evening
Do not change your usual dose without talking to your doctor.
Do not allow the tip of the container to touch the eye or areas around the eye. It may become
contaminated with bacteria that can cause eye infection leading to serious damage of the eye, even
loss of vision. To avoid possible contamination of the container, keep the tip of the container away
from contact with any surface.

you are allergic (hypersensitive) to timolol, beta-blockers or any of the other ingredients of
Timoptol (see section 6 for Further Information)
you have now or have had in the past respiratory problems such as asthma, severe chronic
obstructive bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing
and/or long-standing cough)
you have heart problems
slow heart beat
disorders of heart rhythm (irregular heart beats)
heart failure
“cardiogenic shock” – a serious heart condition caused by very low blood pressure, which may
result in the following symptoms: dizziness and lightheadedness, fast pulse rate, white skin,
sweating, restlessness, loss of consciousness
you are not sure whether you should use Timoptol talk to your doctor or pharmacist.

Instructions for use.

It is recommended that you wash your hands before putting in your eye drops.

Before using the medication for the first time, be sure the
Safety Strip on the front of the bottle is unbroken. A gap
between the bottle and the cap is normal for an unopened


Tear off the safety strip to break the seal.


To open the bottle, unscrew the cap by turning as indicated by the
arrows on top of the cap. Do not pull the cap directly up and away
from the bottle. Pulling the cap directly up will prevent your
dispenser from operating properly.


Tilt your head back and pull your lower eyelid down slightly to form
a pocket between your eyelid and your eye.


Invert the bottle, and press lightly with
your thumb or first finger over the
‘Finger-Push Area’ as shown until a
single drop is dispensed into your eye,
as directed by your doctor.

Take special care with Timoptol

Before you use this medicine tell your doctor if you have now or have had in the past

coronary heart disease (symptoms can include chest pain or tightness, breathlessness or choking),
heart failure

low blood pressure

disturbances of heart rate such as slow heart beat

breathing problems, asthma or chronic obstructive pulmonary disease

poor blood circulation disease (such as Raynaud’s disease or Raynaud’s syndrome)

diabetes as timolol may mask signs and symptoms of low blood sugar

overactivity of the thyroid gland as timolol may mask signs and symptoms

allergies to any medicines

you wear soft contact lenses. Your eye drops contain a preservative which can be deposited on soft
contact lenses. It is important that your lenses are removed before using your eye drops and not
put back into your eyes for 15 minutes.
Tell your doctor before you have an operation that you are using Timoptol as timolol may change
effects of some medicines used during anaesthesia.
If your eye becomes irritated or any new eye problems come on, talk to your doctor straight away.
Eye problems could include redness of the eye or swelling of the eyelids
(see Section 4: Possible Side Effects).
If you suspect that Timoptol is causing an allergic reaction or hypersensitivity (for example, skin rash,
or redness and itching of the eye), stop using Timoptol and contact your doctor immediately.
Tell your doctor if:

you get an eye infection

you injure your eye or have an operation on it

your eye problems get worse or you get any new symptoms.

Use in children and adolescents

There is only very limited data available on the use of timolol in infants and children. For example, in
one small clinical study, timolol, the active ingredient in Timoptol, has been studied in infants and
children aged 12 days to 5 years, who have elevated pressure in the eye(s) or have been diagnosed
with glaucoma. For more information, talk to your doctor.
Timoptol should generally be used with caution in young patients. In newborns, infants and younger
children Timoptol should be used with extreme caution. If coughing, wheezing, abnormal breathing or
abnormal pauses in breathing (apnoea) occur, the use of the medication should be stopped
immediately. Contact your doctor as soon as possible. A portable apnoea monitor may also be helpful.

Using other medicines

Timoptol can affect or be affected by other medicines you are using, including other eye drops for the
treatment of glaucoma. Tell your doctor if you are using or intend to use medicines to lower blood
pressure, heart medicine or medicines to treat diabetes. Please tell your doctor or pharmacist if you
are taking or have recently taken any other medicines, including other eye drops or medicines obtained
without a prescription.

Leaflet revision date: 22.07.14

Like other medicines applied into eyes, timolol is absorbed into the blood. This may cause similar side
effects as seen with intravenous and/or oral beta-blocking agents. Incidence of side effects after
topical ophthalmic administration is lower than when medicines are, for example taken by mouth or
injected. Listed side effects include reactions seen within the class of beta-blockers when used for
treating eye conditions.
