Patient Medication Information: uses, side effects, how to take - Zimed Pf
What is ZIMED® PF used for?
ZIMED® PF eye drops are used to reduce high pressure in the eye in patients with conditions called “open angle glaucoma” or “ocular hypertension”. If the high pressure is not reduced, it could damage your eye sight.
ZIMED® PF does not contain a preservative, so it may be used in patients who could benefit from preservative-free drops.
How does ZIMED® PF work?
ZIMED® PF is an antiglaucoma medicine. It belongs to a group of medicines called prostamides. Your eye contains a clear, watery liquid that feeds the inside of the eye. Liquid is constantly being drained out of the eye and new liquid is made to replace this. If the liquid cannot drain out quickly enough, the pressure inside the eye builds up.
ZIMED® PF works by increasing the flow of liquid that is drained. This reduces the pressure inside the eye.
What are the ingredients in ZIMED® PF?
Medicinal ingredient: Bimatoprost
Non-medicinal ingredients: Citric acid monohydrate, disodium hydrogen phosphate heptahydrate, water, sodium chloride. Small amounts of sodium hydroxide and/or hydrochloric acid may be added to adjust pH.
ZIMED® PF comes in the following dosage forms:
Ophthalmic solution, 0.03% w/v.
Do not use ZIMED®® PF if:
- if you are allergic to bimatoprost, to any of the other ingredients, or to any of the parts of the container (see What are the ingredients in ZIMED® PF).
- If you are allergic to silver. The cap and top of the ZIMED® PF bottle contain silver to prevent bacterial growth. ZIMED® PF may contain traces of silver in the dispensed drops.
To help avoid side effects and ensure proper use, talk to your healthcare professional before you take ZIMED® PF. Talk about any health conditions or problems you may have, including if you:
- are taking or have recently taken any other medicines.
are pregnant or breastfeeding a baby. Talk to your healthcare professional before taking any medicine.
- have an active eye infection or any other eye condition.
- develop another eye condition (an injury or an infection).
- need to have eye surgery.
Other warnings you should know about:
Driving and Using Machinery:
Your sight may become blurred for a short period of time just after using ZIMED® PF. Do NOT drive or use machines until your sight is clear again.
Skin and Eyelashes:
ZIMED® PF may cause your eyelashes to darken, thicken, and grow, and cause the skin around the eyelid to darken too. Avoid having it running onto the cheek or other skin areas.
Eye Colour:
The colour 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 colour are unknown.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
No drug interaction studies have been done with ZIMED® PF.
Your healthcare professional needs to know about other medicines (including eye drops) that you are using or plan to use. This includes medicines obtained without a prescription.
Use of ZIMED® PF with other eye products should be discussed with your healthcare professional beforehand.
How to take ZIMED® PF:
The recommended dose is 1 drop in the affected eye(s) once daily in the evening.
Do NOT use if the tamper-proof seal on the bottle neck is broken before you first use ZIMED® PF.
Do NOT use ZIMED® PF while you wear contact lenses. If you wear contact lenses, take your lenses out before using ZIMED® PF. Wait 15 minutes after using the drops before you put your lenses back in.
If you use ZIMED® PF with another eye drop, wait at least 5 minutes between putting in ZIMED® PF and then the other drops.
- 1. Before putting a drop in the eye, release the first drop away from the eye to check the force needed to get only one drop out of the bottle.
- 2. Wash your hands. Tilt your head back and look at the ceiling.
- 3. Gently pull down the lower eyelid until there is a small pocket.
- 4. Turn the bottle upside down and squeeze it to release one drop into each eye that needs treatment.
- 5. Let go of the lower lid and close your eye for 30 seconds.
- 6.
Wipe off any excess that runs down the cheek or other skin areas.
If a drop misses your eye, try again.
Before putting the cap back on, shake the bottle once in a downwards direction, without touching the dropper tip. This is to remove any liquid on the tip. To avoid infections and eye injury, do not let the tip of the bottle touch your eye or anything else. Put the cap back on and close the bottle right after you have used it.
Usual Dose:
1 drop in the affected eye(s) once daily in the evening.
Overdose:
If you think you, or a person you are caring for, has taken too much ZIMED® PF or in case of accidental swallowing, immediately contact your healthcare professional, regional poison control centre or hospital emergency department, even if there are no symptoms.
Missed Dose:
If you forget to take ZIMED® PF, use a single drop as soon as you remember, and then go back to your regular dosing schedule. Do not take two doses in the same day to make up for the one that you missed.
Talk to your healthcare professional before stopping this treatment. If you stop using ZIMED® PF, the pressure inside your eye may go up.
