Driving and Using Machinery:
Your sight may become blurred for a short period of time just after using TEVA-LATANOPROST. Do NOT drive or use machines until your sight is clear again.
Contact Lenses:
TEVA-LATANOPROST contains a preservative that may be absorbed by contact lenses and stains them a brown colour. The preservative may form a solid with an ingredient (thimerosal) present in many contact lens soaking solutions. Contact lenses can be reinserted 15 minutes after applying the eye drops.
If you are using more than one type of eye drop medication, wait at least 5 minutes between each different eye drop.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
The following may interact with TEVA-LATANOPROST:
Based only on your healthcare professional’s advice, TEVA-LATANOPROST may be used together with other eye drops to further lower intraocular pressure. If more than one eye drop is being used, they should be administered at least 5 minutes apart.
How to take TEVA-LATANOPROST:
Usual adult dose:
1 drop of TEVA-LATANOPROST should be dropped into the affected eye(s) once daily. The best time to do this is in the evening.
Do not allow the dropper tip of the bottle to touch the eye or anything else, because this could contaminate the tip with common bacteria known to cause eye infections.
Serious damage to the eye and loss of vision may result if you use eye drop solutions that have become contaminated.
If you experience any type of eye condition or have surgery, immediately talk to your healthcare professional about continuing to use TEVA-LATANOPROST.
Follow these steps to help you use TEVA-LATANOPROST properly:
- 1. Wash your hands and sit or stand comfortably. If you wear contact lenses, remove them before using your eye drops.
- 2. Once the bottle is opened, hold it in one hand and steady your thumb against your brow or the bridge of your nose.
- 3. Use your index finger to gently pull down the lower eyelid of the affected eye(s) to create a pocket for the drop.
- 4. Gently press the side of the bottle to allow only a single drop to fall into the pocket. Do not let the tip of the bottle touch your eye.
- 5. Close your eye for 2 to 3 minutes.
- 6. If your healthcare professional has told you to use drops in both eyes, repeat the process for the other eye. TEVA-LATANOPROST should be used until your doctor tells you to stop.
Overdose:
If you think you, or a person you are caring for, have taken too much TEVA-LATANOPROST, contact a healthcare professional, hospital emergency department, regional poison control centre or Health Canada’s toll-free number, 1-844 POISON-X (1-844-764-7669) immediately, even if there are no signs or symptoms.
Missed Dose:
If you forget one dose of TEVA-LATANOPROST, continue with the next dose as normal. Do not take two doses to make up for the one that you missed. If you take too many doses, you may irritate your eye.
