    Lumigan Eye Drops (Bimatoprost) Dosage and Side Effects

    LUMIGAN  eye drops are used to reduce high pressure in the eye in patients with open angle glaucoma or ocular hypertension.

    Proper Use of this medication

    Usual dose:

    Normally, you should put one drop of LUMIGAN RC in each eye that needs treatment, once every day, in the evening, following the instructions for use below.

    You must not use the bottle if the tamper-proof seal on the bottle neck is broken before you first use it.

    Follow the following steps to help you use LUMIGAN RC properly:

    1. Wash your hands. Tilt your head back and look at the ceiling.

    2. Gently pull down the lower eyelid to create a small pocket.

    3. Turn the bottle upside down and squeeze it gently to release one drop into each eye that needs treatment.

    4. Let go of the lower lid, and close your eye for 30 seconds.

    If a drop misses your eye, try again.

    LUMIGAN RC contains a preservative called benzalkonium chloride which may discolour soft contact lenses. If you wear contact lenses, remove them before using LUMIGAN RC. Wait 15 minutes after using the drops before you put your lenses back in. If you have been prescribed LUMIGAN RC frequently when you have a dry eye condition or damage to your cornea, your doctor may monitor your eye condition.

    Always use LUMIGAN RC exactly as your doctor has instructed you. If you use LUMIGAN RC with another eye drop, leave at least five minutes between putting in LUMIGAN RC and then the other drops.

    To help prevent infections, do not let the tip of the bottle touch your eye or anything else. Put the cap back on and close the bottle immediately after you have used it.


    In case of accidental oral ingestion or overdose, contact your doctor, regional poison control centre immediately or hospital emergency department, even if there are no symptoms.

    If you accidentally use too many drops, just go back to your regular once a day dosing the next day.

    Missed dose:

    If you forget to take LUMIGAN RC, use a single drop as soon as you remember, and then go back to your regular routine. Do not take two doses to make up for the one that you missed.

    Warnings and Precautions

    This product should not be used if you have severe dry eye.

    BEFORE you use LUMIGAN RC talk to your doctor or pharmacist if:

    • you are taking, or have recently taken, any other medicines, even those not prescribed

    • you are already taking an antiglaucoma preparation as LUMIGAN RC may not reduce the high pressure in the eye if used with another antiglaucoma preparation

    • you are pregnant, intend to become pregnant or breastfeeding a baby. You should ask you doctor or pharmacist for advice before taking any medicine.

    • you have an active eye infection or any other eye condition

    • you develop another eye condition (an injury or an infection)

    • you need to have eye surgery

    • you are allergic to bimatoprost, to any of the other ingredients, such as benzalkonium chloride, or to any of the parts of the container

    Your sight may become blurred for a short period of time just after using LUMIGAN RC. Do not drive or use machines until your sight is clear again.

    LUMIGAN RC may cause your eyelashes to darken, thicken, and grow, and cause the skin around the eyelid to darken too. The color of your iris (eye) may also go darker over time. These changes may be permanent. The change may be more noticeable if you are only treating one eye. The long term effects on the eye color are unknown.

    Hair may grow in areas where LUMIGAN RC solution has been repeatedly in contact with the skin surface. This is why it is important to apply LUMIGAN RC as instructed and to avoid it running onto the cheek or other skin areas.

    Side Effects

    Like all medicines, LUMIGAN RC can have side effects. Most of the side effects are not serious. If these persist or cause you concern, consult your doctor.

    Very common

    • Eye redness


    • Longer eyelashes

    • Eye irritation

    • Red and/or itchy eyelids

    • Darkening of the eyelid

    • Eyelash discolouration

    • Itchy eyes

    • Excessive hair growth

    • Small breaks in the surface of the eye

    Some patients (fewer than 2 in every 100) experience a change in iris color with bimatoprost treatment. The change is a darkening, with the eyes becoming more brown. This usually happens during the first year of treatment. Eye darkening is expected to increase as long as LUMIGAN RC is administered.

    It is not known what this change means over the long term. Talk to your doctor if you notice a change in your iris color; depending on your clinical situation your doctor may want to re-evaluate your treatment.

    This is not a complete list of side effects. For any unexpected effects while taking LUMIGAN RC, contact your doctor or pharmacist.
