1. What Amiriox is and what it is used for
Amiriox contains the active substance bimatoprost, which is a medicine for glaucoma. It belongs to a group of medicines called prostamides.
Bimatoprost is used to reduce elevated intraocular pressure in adults. This medicine can be used alone or in combination with other eye drops called beta-blockers that also reduce pressure.
This medicine works by increasing the amount of fluid drained from the eye, thereby preventing fluid buildup. This reduces the pressure inside the eye. If this pressure is not reduced, it could lead to a condition called glaucoma and damage your vision.
This medicine does not contain preservatives.
2. What you need to know before using Amiriox
Do not use Amiriox
- if you are allergic to bimatoprost or to any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor or pharmacist before starting to use bimatoprost.
Talk to your doctor or pharmacist if:
- you have any breathing problems
- you have liver or kidney problems
- you have previously undergone cataract surgery
- you have or have had low blood pressure or a slow heart rate
- you have had a viral infection or ocular inflammation
During treatment, Amiriox may cause loss of fat around the eye, which can lead to deepening of the eyelid sulcus, sunken eyes (enophthalmos), drooping of the upper eyelids (ptosis), stretching of the skin around the eye (involution of dermatochalasis), and increased visibility of the lower white part of the eye (inferior scleral show). These changes are usually mild, but if they become more pronounced, they may affect your field of vision. These changes may resolve if you stop using Amiriox. Amiriox may also cause darkening and growth of the eyelashes, as well as darkening of the skin around the eyelid. It may darken the color of the iris. These changes may be permanent and more noticeable if only one eye is being treated.
If you have a history of contact hypersensitivity to silver, you should not use this medicine.
Children and adolescents
Bimatoprost has not been studied in individuals under 18 years of age and therefore should not be used in patients under 18 years of age.
Other medicines and Amiriox
Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
If you are using other eye drops, wait at least 5 minutes between the administration of bimatoprost and the other eye drops. Ophthalmic ointments should be administered last.
Pregnancy, breastfeeding and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Bimatoprost may pass into breast milk; therefore, you should not breastfeed while using this medicine.
Driving and using machines
Blurred vision may occur for a short period of time after using this medicine. Do not drive or operate machinery until your vision clears.
Amiriox contains phosphates
This medicine contains 0.95 mg of phosphates per ml. If you have severe damage to the transparent outer layer at the front of the eye (cornea), treatment with phosphates may, in very rare cases, lead to blurred vision due to calcium accumulation.
3. How to use Amiriox
Follow exactly the instructions for administering this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.
Bimatoprost should be used only in the eye. The recommended dose is one drop of bimatoprost in each eye requiring treatment, once daily, in the late afternoon.
Bimatoprost has not been studied in patients wearing contact lenses. Remove contact lenses before application and wait at least 15 minutes before reinserting them.
If you use bimatoprost with another eye medication, wait at least 5 minutes between using bimatoprost and the other eye medication.
Do not use the medicine more than once a day, as this may reduce the effectiveness of treatment.
This medicine is a sterile solution that contains no preservatives. See section 6. Appearance of Amiriox and contents of the container.
Before administering the eye drops:
- When using for the first time, practice using the dropper bottle by gently squeezing until one drop is dispensed into the air, away from the eye.
- Once you are confident that you can administer one drop at a time, choose the position that is most comfortable for instilling the drops (sitting, lying on your back, or standing in front of a mirror).
Instructions for use:
- Wash your hands thoroughly before using this medicine.
- Do not use the medicine if the container or bottle is damaged.
- When using the medicine for the first time, unscrew the cap after ensuring that the security seal ring has not been broken. You should feel slight resistance until the security seal ring breaks (see drawing 1).
- If the security seal ring becomes loose, discard it, as it could fall into the eye.
- Tilt your head backward and gently pull down the lower eyelid to form a pouch between the eye and the eyelid (see drawing 2). Do not let the tip of the bottle touch the eye, eyelids, or fingers.
- Gently squeeze the center of the bottle to release one drop into the eye (see drawing 3). There may be a delay of a few seconds between squeezing and the drop falling. Be sure not to squeeze too hard. If you are unsure how to use this medicine, consult your doctor, pharmacist, or nurse.
- With the eye closed, press your finger against the corner of the closed eye (where the eye meets the nose) and hold for 2 minutes. This ensures the drop is absorbed by the eye and helps prevent the medicine from reaching the rest of the body.
- Repeat steps 5, 6, and 7 in the other eye if your doctor has instructed you to do so.
- After use, shake the bottle once in a downward direction, without touching the dropper tip, to remove any residual liquid from the tip. This will ensure proper administration of subsequent drops. Replace and tighten the cap on the bottle (see drawing 4).
If a drop does not reach your eye, try again.
To help prevent infections and avoid eye injury, ensure the tip of the container does not touch the eye or any other surface. Replace the cap and close the container immediately after use.

If you use more Amiriox than you should
If you use more Amiriox than prescribed, it is unlikely to cause you any serious harm. Apply the next dose at the usual time. If you are concerned, consult your doctor or pharmacist.
If you forget to use Amiriox
If you forget to apply this medicine, instill one drop as soon as you remember, and then return to your regular routine. Do not apply a double dose to make up for a missed dose.
If you stop using Amiriox
This medicine must be used every day for it to work properly. If you stop using this medicine, the pressure inside the eye may increase; therefore, consult your doctor before stopping treatment.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
