How to take ISOPTO CARPINE:



1 2 3
- Get the ISOPTO CARPINE bottle and a mirror.
- Wash your hands.
- Twist off the bottle cap.
- After cap is removed: if security collar is loose, remove before using product.
- Hold the bottle, pointing down, between your thumb and fingers.
- Tilt your head back.
- Pull down your lower eyelid with a clean finger until there is a ‘pocket’ between the eyelid and your eye. The drop will go in here (picture 1).
- Bring the bottle tip close to the eye. Do this in front of a mirror if it helps.
- Do not touch your eye or eyelid, surrounding areas or other surfaces with the dropper. It could infect the drops.
- Gently press on the base of the bottle to release one drop of ISOPTO CARPINE at a time.
- Do not squeeze the bottle: it is designed so that a gentle press on the bottom is all that it needs (picture 2).
- After using ISOPTO CARPINE, press a finger into the corner of your eye, by the nose (picture 3). This helps to stop ISOPTO CARPINE getting into the rest of the body.
- If a drop misses your eye, try again.
- If you use drops in both eyes, repeat the steps for your other eye.
- Close the bottle cap firmly immediately after use.
- Wash your hands after use.
If you are using other eye medicines, wait at least 5-10 minutes between applying ISOPTO CARPINE and the other drops. Eye ointments should be applied last.
Usual dose:
Apply 2 drops in the affected eye(s) 3 or 4 times a day or as directed by your healthcare professional.
Overdose:
If you use more ISOPTO CARPINE than you should, rinse it all out with warm water. Do not put in any more drops until it is time for you next regular dose.
Symptoms of an overdose may include: headache, salivating, sweating, fainting, slow heart rate, low blood pressure, stomach cramps, vomiting, asthma or diarrhea.
In severe cases of an overdose, a healthcare professional may need to treat you with another drug known as an anticholinergic.
| If you think you, or a person you are caring for, have taken too much ISOPTO CARPINE, contact a healthcare professional, hospital emergency department, or regional poison control centre immediately, even if there are no symptoms. |
