1. What TRUSOPT PRESERVATIVE-FREE is and what it is used for
TRUSOPT Preservative-Free contains dorzolamide which belongs to a group of medicines called “carbonic anhydrase inhibitors.”
This medicine is prescribed to lower raised pressure in the eye and to treat glaucoma. This medicine can be used alone or in addition to other medicines
which lower the pressure in the eye (so-called beta-blockers).
2. What you need to know before you use TRUSOPT Preservative-Free
Do not use TRUSOPT Preservative-Free
- if you are allergic to dorzolamide hydrochloride or any of the other ingredients of this medicine (listed in section 6).
- if you have severe kidney impairment or problems, or a prior history of kidney stones.
If you are not sure whether you should use this medicine, contact your doctor or pharmacist.
Warnings and precautions
Talk to your doctor or pharmacist before using TRUSOPT Preservative-Free.
Tell your doctor or pharmacist about any medical problems you have now or have had in the past, including eye problems and eye surgeries, and about
any allergies to any medications.
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.
If you suspect that TRUSOPT Preservative-Free is causing an allergic reaction (for example, skin rash, severe skin reaction, or itching), stop using this
medicine and contact your doctor immediately.
If you wear contact lenses, you should consult your doctor before using TRUSOPT Preservative-Free.
Use in children
TRUSOPT (preserved formulation) has been studied in infants and children less than 6 years of age who have raised pressure in the eye(s) or have been
diagnosed with glaucoma. For more information talk to your doctor.
Use in elderly
In studies with TRUSOPT (preserved formulation), the effects of this medicine were similar in both elderly and younger patients.
Use in patients with liver impairment
Tell your doctor about any liver problems you now have or have suffered from in the past.
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines (including eye drops). This is particularly important
if you are taking another carbonic anhydrase inhibitor such as acetazolamide, or a sulpha drug.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
Use in pregnancy
You should not use this medicine during pregnancy. Tell your doctor if you are pregnant or intend to become pregnant.
Use in breast-feeding
You should not use this medicine during breast-feeding. Tell your doctor if you are breast-feeding or intend to breast-feed.
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 TRUSOPT Preservative-Free,
such as dizziness and 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 TRUSOPT Preservative-Free
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.
When this medicine is used alone, the recommended dose is one drop in the affected eye(s) in the morning, in the afternoon and in the evening.
If your doctor has recommended you use this medicine with a beta-blocker eye drop to lower eye pressure, then the recommended dose is one drop of
TRUSOPT Preservative-Free in the affected eye(s) in the morning and in the evening.
If you are using TRUSOPT Preservative-Free with another eye drop, the drops should be instilled at least 10 minutes apart.
Do not change the dose of the drug without consulting 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 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.
Instructions for use:
The solution from one individual single dose container of TRUSOPT Preservative-Free is to be used immediately after opening for administration to the
affected eye(s). Since sterility cannot be maintained after the individual single dose container is opened, a new container must be opened prior to each
use and must be discarded immediately after administration. Each single dose container contains enough solution for both eyes.
1. Open the foil sachet which contains 15 individual single dose containers. There are three strips of 5 single dose containers each in the sachet.
2. First wash your hands then break off one single dose container from the strip and twist open the top of the single dose container as shown.

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

4. Put one drop in the affected eye(s) as directed by your doctor.

5. After putting the drop into the eye, throw away the used single dose container even if there is solution remaining to avoid contamination of the
preservative free solution.
6. Store the remaining containers in the foil sachet; the remaining containers must be used within 15 days after opening of the sachet. If there are any
containers left 15 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 use more TRUSOPT Preservative-Free than you should
If you put too many drops in your eye or swallow any of the contents of the container, you should contact your doctor immediately.
If you forget to use TRUSOPT Preservative-Free
It is important to take this medicine as prescribed by your doctor. If you miss a dose, take 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 TRUSOPT Preservative-Free
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.
