If you develop any eye irritation or any new eye problems such as redness of the eye or swelling of the eyelids, contact your doctor immediately.

Tell your doctor if you develop an eye infection, receive an eye injury, have eye surgery, or develop a reaction including new or worsening symptoms.
When this medicine is instilled into the eye it may affect the entire body.
This medicine has not been studied in patients wearing contact lenses. If you wear soft contact lenses, you should consult your doctor before using this medicine.

Use in patients with liver impairment
Tell your doctor about any liver problems you now have or have suffered from in the past.
Other medicines and this medicine
This medicine 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. Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. This is particularly important if you are:
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
Use in pregnancy
Do not use this medicine if you are pregnant unless your doctor considers it necessary.
Use in breast-feeding
Do not use this medicine 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
No studies on the effects on the ability to drive or use machines have been performed. There are side effects associated with this medicine, such as blurred vision, which may affect your ability to drive and/or operate machinery. Do not drive or operate machinery until you feel well or your vision is clear.
3. HOW TO USE THIS MEDICINE
Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The appropriate dosage and duration of treatment will be established by your doctor.
The recommended dose is one drop in the affected eye(s) in the morning and in the evening.
If you are using this medicine with another eye drop, the drops should be instilled at least 10 minutes apart.
Do not change the dose of the medicine without consulting your doctor.
If you have difficulty administering your eye drops, seek the assistance of a family member or carer.
Do not allow the single-dose container to touch the eye or areas around the eye. It could cause injury to your eye. It may also become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the single-dose container, wash your hands before using this medicine and keep the tip of the single-dose container away from contact with any surface. A new single-dose container should be opened immediately prior to each use; there is enough solution in each container for both eyes if your doctor has told you to use the drops in both eyes.
Discard the opened container with any remaining contents immediately after use
Instructions for use:
Open the sachet which contains a strip of 5 individual single- dose containers.
1. Wash your hands.
2. Take the strip of containers from the sachet.
3. Detach one single-dose container from the strip.
4. Put the remaining strip back in the pouch and fold the edge to close the pouch.
5. Twist the lid to open the container. Continue twisting until the lid detaches. Do not pull the lid to remove.
6. Hold the container between your thumb and index finger.
7. Check for any sharp edges or burrs around the container opening before administering a drop.
8. Tilt your head backwards or lie down. Look up and pull the lower eyelid downwards with the other hand. Do not allow any part of the container to touch your eye or any area around your eye. Gently squeeze the container to let one drop fall into the space between the lid and the eye. Do not blink while applying the drop to your eye. Each single-dose container contains enough solution for both eyes.
9. Close your eye and press the inner corner of the eye with your finger for about two minutes. This helps to stop the medicine from getting into the rest of the body.
10. Wipe off any excess solution from the skin around the eye.
If your doctor has told you to use drops in both eyes, repeat steps 7 to 10 for your other eye. After putting the drop into the eye(s), throw away the used single-dose container even if there is solution remaining to avoid contamination of the preservative free solution.
Store the remaining containers in the sachet; the remaining containers must be used within 7 days after opening of the sachet. If there are any containers left 7 days after opening the sachet they should be safely thrown away and a fresh sachet opened. It is important to continue to use the eye drops as prescribed by your doctor.
If you are not sure how to administer your medicine, ask your doctor, pharmacist or nurse.
If you use more of this medicine than you should
If you put too many drops in your eye or swallow any of the contents of the container, among other effects, you may become light-headed, have difficulty breathing, or feel that your heart rate has slowed. Contact your doctor immediately.
If you forget to use this medicine
It is important to take this medicine as prescribed by your doctor.
If you miss a dose, use it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule.
Do not take a double dose to make up for the forgotten dose.
If you stop using this medicine
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.
