WHAT OTINAN IS AND WHAT IT IS USED FOR

Otinan is a sterile eye drop solution. Otinan contains dorzolamide, a sulphonamide-related compound, as the
active ingredient.
Otinan is an ophthalmic carbonic anhydrase inhibitor which reduces high pressure in the eye.
It is indicated in the treatment of elevated intra-ocular pressure in conditions such as ocular hypertension and
glaucoma (open-angle glaucoma, pseudo-exfoliative glaucoma). Otinan can be used alone or in addition to
other medicines which lower the pressure in the eye (so-called beta-blockers).

2.

BEFORE YOU USE OTINAN

Do not use Otinan
if you are allergic (hypersensitive) to dorzolamide or any of the other ingredients of this solution.
if you have severe kidney problems.

Take special care with Otinan
Before treatment with Otinan, tell your doctor
if you have or have had liver problems in the past
if you have been told you have a corneal defect
if you have had any allergies to any medicines
if you have had, or are about to have eye surgery
if you have suffered an eye injury or have an eye infection
if you have a prior history of kidney stones
if you are taking orally another carbonic anhydrase inhibitor
if you wear contact lenses (see the section ‘Important information about some of the ingredients of
Otinan’).

You should contact your doctor immediately if you develop any eye irritation or any new eye problems such
as redness of the eye or swelling of the surface layer of the eye or eyelids.
Stop using Otinan and contact your doctor immediately if you suspect that Otinan is causing an allergic
reaction (for example, skin rash or itching, inflammation of the eye).
Use in children
Otinan 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.
Using other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including
medicines obtained without a prescription.
In particular you should tell your doctor if you are taking another carbonic anhydrase inhibitor such as
acetazolamide. You may be taking this type of medicine by mouth, as eye drops, or by some other method.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine. Tell your doctor if you are pregnant or
planning to become pregnant. Otinan should not be used during pregnancy unless your doctor still
recommends it.
Otinan should not be used while breast-feeding.
Driving and using machines
Otinan may cause dizziness and visual disturbances in some patients. Do not drive or use any tools or
machines until the symptoms have cleared.
Important information about some of the ingredients of Otinan
Otinan contains the preservative benzalkonium chloride.

Benzalkonium chloride may cause eye irritation.

Benzalkonium chloride is known to discolour soft contact lenses.

Avoid contact with soft contact lenses.

Remove contact lenses prior to application and wait until 15 minutes before reinsertion.

HOW TO USE OTINAN

Always use Otinan exactly as your doctor has told you. You should 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 Otinan is used alone, the usual dose is one drop in the affected eye(s) three times a day, for example in
the morning, in the afternoon and in the evening.
If your doctor has recommended you use Otinan with a beta-blocker eye drop (medicines which lower the
pressure of the eye), then the usual dose is one drop of Otinan in the affected eye(s) two times a day, for
example in the morning and in the evening.
If you use Otinan with another eye drop, leave at least 10 minutes between putting in Otinan and the other
medicine. Alternatively if you are going to use Otinan to replace another eye drop medicine, used to lower
eye pressure, you should stop using the other medicine after taking the proper dosing on one day, and start
Otinan on the next day.
Do not change the dosage of the drug without consulting your doctor. If you must stop treatment, contact
your doctor immediately.

Do not allow the tip of the container to touch your eye or areas around your 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 container, keep the tip of the container away from contact
with any surface.
Instructions for proper use:
It is recommended that you wash your hands before putting in your eye drops.
It may be easier to apply your eye drops in front of a mirror.

1. Before using the medication for the first time, be sure that the tamper-proof seal on the bottle neck is
unbroken. A gap between the bottle and the cap is normal for an unopened bottle.
2. Take off the cap of the bottle.
3. Tilt your head back and gently pull your lower eyelid down to form a small pocket between your eyelid
and your eye.
4. Invert the bottle, and squeeze it until a single drop is dispensed into the eye as directed by your doctor. DO
NOT TOUCH YOUR EYE OR EYELID WITH THE DROPPER TIP.
5. Repeat steps 3 & 4 with the other eye if instructed to do so by your doctor.
6. Put the cap back on and close the bottle straight after you have used it.
If you use more Otinan than you should
If you put too many drops in your eye or swallow any of the contents, you should contact your doctor
immediately.
If you forget to use Otinan
It is important to use Otinan as prescribed by your doctor.
If you miss a dose, apply 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 forgotten individual doses.
If you stop using Otinan
Otinan should be used every day to work properly. If you must stop treatment, contact your doctor
immediately.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
