1. What is Arzolan and what is it used for

Arzolan is a sterile eye drop solution. Arzolan contains the active substance dorzolamida, a compound related to sulfonamides.

Dorzolamida is a carbonic anhydrase inhibitor for ophthalmic use and reduces high pressure inside the eye.

It is indicated for the treatment of high intraocular pressure in patients with ocular hypertension and glaucoma (open-angle glaucoma, pseudoexfoliative glaucoma). Arzolan can be used alone or in combination with other medications that decrease pressure inside the eye (called beta-blockers).

Children and adolescents

Arzolan should only be used in children if the benefits justify the risks. Your doctor will advise you.

Using Arzolan with other medicines

Tell your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription.

In particular, you should consult your doctor if you are using another carbonic anhydrase inhibitor such as acetazolamide. You may be using this type of medicine orally, as eye drops, or in any other way.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before using any medicine. Inform your doctor if you are pregnant or plan to become pregnant. You should not use Arzolan during pregnancy unless your doctor recommends it.

You should not use Arzolan during breastfeeding.

Driving and using machines

Arzolan may cause dizziness and visual disturbances in some patients. Do not drive or operate machinery until the symptoms have disappeared.

Arzolan contains benzalkonium chloride

Avoid contact with soft contact lenses.

Remove contact lenses before application and wait at least 15 minutes before putting them back.

It changes the color of soft contact lenses.

3. How to use Arzolan

Follow the instructions for using Arzolan exactly as indicated by your doctor. Consult your doctor or pharmacist if you have any doubts.

The appropriate dosage and duration of treatment will be determined by your doctor.

When Arzolan is used alone, the usual dose is one drop in the affected eye(s) three times a day, i.e., in the morning, afternoon, and evening.

If your doctor has recommended using Arzolan with a beta-blocker eye drop (medicines that decrease the pressure inside the eye), the usual dose is one drop in the eye(s) twice a day, for example, in the morning and afternoon.

If you are going to use Arzolan with another eye drop, the applications of the different medicines should be spaced at least 10 minutes apart. Similarly, when you are going to replace another eye drop medicine with Arzolan, used to decrease eye pressure, you should stop using the other medicine after taking the appropriate dose for one day and start using Arzolan the next day.

Do not change the dose of the medicine without consulting your doctor. If you need to interrupt treatment, consult your doctor immediately.

Do not let the tip of the container touch the eyes or the surrounding areas. It may be contaminated with bacteria that can cause eye infections that can lead to serious damage to the eyes, including vision loss. To avoid possible contamination of the container, avoid letting the tip of the container come into contact with any surface.

Instructions for use:

It is recommended to wash your hands before applying the eye drops.

Sit down, if possible, in front of a mirror to facilitate application.

Eye open with hand holding eye drop applicator approaching the surface of the eye

  1. Before using the medicine for the first time, make sure the security strip on the neck of the bottle is intact. When the bottle has not been opened yet, it is normal to have a space between the bottle and the cap.
  2. Remove the cap from the bottle.
  3. Tilt your head back and gently separate the lower eyelid, forming a small gap between the eyelid and the eye.
  4. Invert the bottle and press until a single drop is dispensed into the eye according to your doctor's instructions. DO NOT TOUCH THE EYE OR EYELID WITH THE DROPPER TIP.
  5. Close your eye and press the inner corner of the eye with your finger for about two minutes. This helps prevent the medicine from reaching the rest of the body.
  6. Repeat steps 3 and 4 in the other eye if your doctor has indicated it.
  7. Replace the cap and close the bottle immediately after use.

If you use more Arzolan than you should

If you apply too many drops in the eye or swallow part of the contents of the bottle, consult your doctor immediately.

If you forget to use Arzolan

It is important to administer Arzolan as your doctor has indicated.

If you forget to apply a dose, you should administer it as soon as possible. However, if it is almost time for the next dose, do not administer the missed dose and continue with the normal dosing schedule.

Do not use a double dose to make up for missed doses.

If you stop using Arzolan

Arzolan should be used daily to have the desired effect. If you need to interrupt treatment, consult your doctor immediately.
