Pregnancy, breastfeeding, and fertility
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Trust should not be used during pregnancy. Therefore, tell your doctor if you are or plan to become pregnant.
If treatment with Trusopt is necessary, breastfeeding is not recommended. Tell your doctor if you are breastfeeding or plan to breastfeed.
Driving ability and use of machinery
No studies regarding effects on the ability to drive and use machines have been performed. Trusopt can cause side effects such as dizziness and blurred vision, which can affect your ability to drive or use machinery. Wait to drive or use machines until you feel well or your vision is clear.
You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with your doctor or pharmacist if you are unsure.
Trusopt contains excipients
Trusopt contains benzalkonium chloride
This medicine contains approximately 0.002 mg benzalkonium chloride per drop corresponding to 0.075 mg/ml.
Benzalkonium chloride can be absorbed by soft contact lenses and can discolor the contact lenses. Remove contact lenses before using the medicine and wait at least 15 minutes before putting them back in.
Benzalkonium chloride can be irritating to the eyes, especially if you have dry eyes or problems with the cornea (the clear membrane at the front of the eye). If you feel irritation, tingling, or pain in the eye after using the medicine, consult a doctor.
How to use Trusopt
Always use this medicine as directed by your doctor. Ask your doctor or pharmacist if you are unsure. The appropriate dose and duration of treatment are determined by the doctor.
When this medicine is used alone, the recommended dose is 1 drop in the affected eye(s) in the morning, afternoon, and evening.
If your doctor recommends using this medicine in combination with other eye drops called beta blockers to lower the pressure in the eye, the recommended dose is 1 drop of Trusopt in the affected eye(s) in the morning and the evening.
If Trusopt is used together with other eye drops, the eye drops should be taken at least 10 minutes apart.
Make sure the tip of the bottle does not touch the eye or the area around the eye. This can lead to the drops being contaminated with bacteria, which can cause an eye infection. Such an infection can lead to serious eye damage, even loss of vision.
Wash your hands before using this medicine to avoid contamination and make sure the tip of the bottle does not touch other surfaces. If you think your medication may have been contaminated, or if you develop an eye infection, contact your doctor immediately regarding the continued use of this bottle.
Instructions for use:
Do not use the bottle if the plastic sealing strip around the neck of the bottle is missing or broken. Remove the sealing strip when opening the bottle for the first time.
Each time you use Trusopt:
[OCUMETER PLUS bottle only]
1. Make sure the sealing strip on the front of the bottle is unbroken before using the bottle for the first time. A gap between the bottle and cap is normal for an unopened bottle.
2. First wash your hands, then remove the sealing strip.
3. Open the bottle by unscrewing the cap, and turning in the direction of the arrows. Do not pull the cap straight up from the bottle, as this may impair the function of the bottle tip.
4. Tilt your head back and pull down the lower eyelid slightly so that a pocket is formed between the eyelid and the eye.
5. Turn the bottle upside down. Press lightly with your thumb or index finger on the area to be pressed until a drop has been instilled into the eye, as directed by your doctor.
DO NOT TOUCH YOUR EYE OR EYELID WITH THE TIP OF THE BOTTLE.
6. If it is difficult to get drops out after opening the bottle for the first time, put the cap back on the bottle (do not tighten it too tightly). Remove the hat as usual by turning it according to the arrows.
7. If your doctor prescribed treatment for your other eye, repeat steps 4 and 5.
8. Screw the cap so that it is fixed on the bottle. The arrow on the left side of the cap must line up with the arrow on the left side of the bottle to be properly closed. Be careful not to screw the cap on too tightly as this may damage the bottle and cap.
9. The hole in the tip is designed to get a single drop out, so DO NOT enlarge the hole in the bottle tip yourself.
10. When you have finished using the bottle, there will be a certain amount of medicine left. This is normal because an extra amount of medicine has been added. You will be given the amount prescribed by your doctor. Do not try to get the excess medicine out of the bottle.
If you have used too much Trusopt
If you put too many drops in the eye, have swallowed some of the contents of the container, or if, for example, a child accidentally swallowed the drops, immediately contact a doctor or hospital for an assessment of the risk and advice.
If you forget to use Trusopt
It is important to take Trusopt as prescribed by your doctor. If you forget to take a dose, take it as soon as possible. If, on the other hand, it is time to take the next dose, then skip the forgotten dose and then regularly follow the dosing schedule.
Do not take a double dose to make up for a missed dose.
If you stop using Trusopt
If you want to stop treatment with Trusopt, consult your doctor first. If you have further questions about this medicine, contact your doctor or pharmacist.
