1. WHAT TIMOPTOL Unit Dose IS AND WHAT IT IS USED FOR
Timoptol Unit Dose contains a substance called timolol which belongs to a group of medicines called beta-blockers. Timolol lowers the pressure in your eye(s). It is used to treat glaucoma, when the pressure in the eye is raised.
2. BEFORE YOU USE TIMOPTOL Unit Dose
Do not use Timoptol Unit Dose if:
• you are allergic (hypersensitive) to timolol, beta-blockers or any of the other ingredients of Timoptol Unit Dose (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.
If you are not sure whether you should use Timoptol Unit Dose talk to your doctor or pharmacist.
Take special care with Timoptol Unit Dose
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 heartbeat
• 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 maleate may mask signs and symptoms
• you wear soft contact lenses
Tell your doctor before you have an operation that you are using Timoptol Unit Dose 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 Unit Dose is causing an allergic reaction or hypersensitivity (for example, skin rash, or redness and itching of the eye), stop using Timoptol Unit Dose 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 Unit Dose eye drops, has been studied in infants and children aged 12 days to 5 years, who have raised pressure in the eye(s) or have been diagnosed with glaucoma. For more information, talk to your doctor.
Timoptol Unit Dose should generally be used with caution in young patients. In newborns, infants and younger children Timoptol Unit Dose 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 Unit Dose 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. It is important to tell your doctor before using Timoptol Unit Dose if you are taking one or more of the following medicines:
• a calcium antagonist, such as nifedipine, verapamil or diltiazem, often used to treat high blood pressure, angina, an abnormal heartbeat or Raynaud's syndrome
• digoxin, a medicine used to relieve heart failure or treat abnormal heartbeat
• medicines known as catecholamine-depleting agents, such as rauwolfia alkaloids/reserpine used for high blood pressure
• medicines called pressor amines, such as adrenaline used to treat severe allergic reaction
• quinidine (used to treat heart conditions and some types of malaria)
• antidepressants known as fluoxetine and paroxetine
• clonidine, a medicine used to treat high blood pressure
• other beta-blockers taken by mouth or used as eye drops, because they belong to the same group of medicines as Timoptol Unit Dose and could have an additive effect.
Pregnancy and breast-feeding
Ask your doctor for advice before taking any medicine.
Use in pregnancy
Do not use Timoptol Unit Dose if you are pregnant unless your doctor considers it necessary.
Use in breast-feeding
Do not use Timoptol Unit Dose if you are breast-feeding. Timolol may get into your milk. Ask your doctor for advice before taking any medicine during breast-feeding
Driving and using machines
There are possible side effects associated with Timoptol Unit Dose, 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.
3. HOW TO USE TIMOPTOL Unit Dose
Always use Timoptol Unit Dose eye drops solution 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 the dose of this medicine without talking to your doctor.
Do not allow the tip of the single dose 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 single dose container, keep the tip of the single dose container away from contact with any surface.
Instructions for use.
Open the drops container just before you want to use it. After using the drops, throw away what is left. This is because the drops cannot be kept free of bacteria after being opened.
1. Open the foil sachet containing the individual single dose containers. There are three strips of 5 single dose containers in each sachet.
2. First wash your hands and then break off a single dose container from the strip. Then twist open the top of the single dose container as shown.
3. Tilt your head back and pull your lower eyelid now slightly.
Put one drop in the affected eye(s) as directed by your doctor. Each single dose container contains enough solution for both eyes.
5. After using Timoptol Unit Dose, press a finger into the corner of your eye, by the nose for 2 minutes. This helps to stop timolol getting into the rest of your body.
6. After putting the drop into the eye(s), throw away the used container, even if there is solution remaining, to avoid contamination.
7. Store the remaining containers in the foil sachet. The containers must be used within 15 days after opening the sachet. If any containers are left 15 days after opening the sachet, throw them away and open a new one.
Children and Adolescents
Before you or your child starts to take Timoptol Unit Dose, your doctor or your child's doctor will have carried out a detailed medical examination and decided whether or not this medicine is suitable. You or your child, especially a newborn, should be closely monitored for one to two hours after the first dose and carefully monitored for any signs of side effects until surgery is carried out.
Method of administration:
One drop only of Timoptol Unit Dose should be instilled into the affected eye(s) each time. Follow the “Instructions for Use” above when administering the eye drops. After instillation keep the eyes closed for as long as possible (e.g. 3 - 5 minutes) and apply pressure to the corner of the eye closest to the nose to prevent the eye drops spreading throughout the body.
Duration of treatment:
Your doctor or your child's doctor will decide for how long the eye drops will be needed.
If you use more Timoptol Unit Dose than you should
If you put too many drops in your eye or swallow any of the drops, you may:
• have a headache
• feeling dizzy or light-headed
• have difficulty breathing
• chest pain
• feel that your heart rate has slowed down.
If this happens, contact your doctor immediately.
If you forget to use Timoptol Unit Dose
It is important to take Timoptol Unit Dose as prescribed by your doctor.
• If you miss a dose, use the drops as soon as possible.
• If it is almost time for the next dose, skip the missed dose and take the next dose at the usual time.
• Do not take a double dose to make up for the forgotten dose.
If you stop using Timoptol Unit Dose
If you want to stop using this medicine talk to your doctor first. If you have any further questions on the use of this product, ask your doctor or pharmacist.

Like all medicines Timoptol can cause side effects, although not everybody gets them.
You can usually carry on taking the drops, unless the effects are serious. If you're worried, talk to a doctor or pharmacist. Do not stop using Timoptol Unit Dose without speaking to your doctor.
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.
If you develop allergic reactions including swelling beneath the skin that can occur in areas such as the face and limbs, and can obstruct the airway which may cause difficulty swallowing or breathing, hives or itchy rash, localized and generalized rash, itchiness, severe sudden life-threatening allergic reaction, stop taking your eye drops and seek medical attention immediately.
