Instructions for use
Before instillation of the eye drops:

Wash your hands before opening the bottle.
Do not use this medicine if you notice that the tamper-proof seal on the bottle neck is
broken before you first use it.
When using for the first time, before delivering a drop to the eye, you should first of all
practise using the dropper bottle by squeezing it slowly to deliver one drop into the air,
away from the eye.
When you are confident that you can deliver one drop at a time, choose the position that
you find most comfortable for the instillation of the drops (you can sit down, lie on your
back, or stand in front of a mirror).

1. Hold the bottle directly below the cap and turn the cap to open the bottle. Do not touch
anything with the tip of the bottle to avoid contamination of the solution.

2. Tilt your head backwards and hold the bottle above your eye.

3. Pull the lower eyelid down and look up. Squeeze the bottle gently in the middle and let a
drop fall into your eye. Please note that there might be a few seconds delay between
squeezing and the drop coming out. Do not squeeze too hard.
If you are not sure how to administer your medicine, ask your doctor, pharmacist or nurse.

4. Blink a few times so that the drop spreads over the eye.
5. Repeat the instructions 2. – 4. to deliver a drop into the other eye also, if your doctor has
instructed you to do this. Sometimes only one eye needs to be treated and your doctor will
advise if this applies to you and which eye needs treatment.

6. After use and prior to recapping, the bottle should be shaken once in a downwards
direction, without touching the dropper tip, in order to remove any residual liquid on the tip.
This is necessary in order to ensure delivery of subsequent drops.
7. After you have used all doses there will be some Dorzolamide + Timolol PharmaSwiss left
in the bottle. You should not be concerned since an extra amount of Dorzolamide + Timolol
PharmaSwiss has been added and you will get the full amount of Dorzolamide + Timolol
PharmaSwiss that your doctor has prescribed. Do not attempt to use the excess medicine
remaining in the bottle after you have completed the course of treatment.
Do not use the eye drops for longer than 28 days after first opening the bottle.
If you use more Dorzolamide + Timolol PharmaSwiss 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 Dorzolamide + Timolol PharmaSwiss
It is important to use 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 use a double dose to make up for the forgotten dose.
If you stop using Dorzolamide + Timolol PharmaSwiss
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.
