What you will receive
Trusopt is the originator brand name, made by Merck. We use it to identify the medicine; the pack you receive is a generic equivalent, not the original Trusopt.
- The same active ingredient (Dorzolamide) at the same strength.
- The exact brand supplied depends on what is in stock when your order ships.
FAQ
Which generic dorzolamide strengths and bottle counts can I order?
Trusopt comes as 2% bottles, with counts of 1, 2 or 3 bottles. This is generic dorzolamide, not the original Trusopt. Larger packs cost less per bottle.
How are generic dorzolamide bottles delivered to Hong Kong?
Generic dorzolamide orders ship by tracked courier in 5 to 9 business days with online tracking. Every parcel is plain and unbranded, with nothing outside about the contents. If it does not arrive within the delivery window or arrives damaged, it is sent again free, or refunded if that is not possible.
Can I use Trusopt with other eye drops?
Yes, and many people do — a second pressure-lowering drop is often added to the routine. Leave about ten minutes between the two, and keep to the same order each time so you do not lose track. Using them back to back can wash the first drop out of the eye before it has had time to work.
Can I wear contact lenses while using Trusopt?
Remove soft lenses before the drop goes in, then wait about 15 minutes to put them back. Otherwise the liquid sits trapped between lens and eye. Glasses are the simpler choice during the first weeks, while your eyes get used to the drops.
What does the 2% on the bottle mean?
The label gives the concentration: 2% means two parts of dorzolamide in every hundred parts of liquid. You never measure or dilute anything, since each drop from the bottle already has that strength and the same bottle serves both eyes.
Can I stop using Trusopt if my eye pressure feels fine?
The drops are what keep the pressure down, so stopping usually lets it creep back up, and high eye pressure is not something you can feel. Running out for a few days is not ideal either, so it makes sense to order the next pack before the current bottle runs dry.
About Trusopt
What the drops are for
Trusopt works on the pressure inside the eye. Its active ingredient, dorzolamide, comes as a 2% solution, and it is used in open-angle glaucoma, where the optic nerve is being damaged, and in ocular hypertension (raised pressure inside the eye with no nerve damage yet). The eye constantly makes a clear fluid that keeps its shape and feeds its front tissues. Dorzolamide slows an enzyme the eye uses to make that fluid, so less is produced and there is less strain on the optic nerve at the back of the eye. Glaucoma damage is painless and easy to miss early on, which is why the drops go in every day rather than only when something feels wrong. They hold pressure steady; they cannot undo nerve damage that has already happened.
How to put them in
One drop in each affected eye, three times a day, spaced through your waking hours. Wash your hands, tilt your head back and pull the lower lid down into a small pocket. Let the drop fall into the pocket without letting the bottle tip touch your eye, lid or lashes, which keeps the bottle clean. Close the eye gently and press the inner corner by the nose for a minute. That press is worth the trouble: it keeps more of the drop against the eye and sends less down the tear duct, which is where the bitter taste at the back of the mouth comes from. Wipe off anything that runs onto your cheek.
Side effects
A short sting or burn as the drop lands is common, and a bitter taste afterwards is expected rather than a sign that something is wrong. Vision may blur for a few minutes, and eyes can water, itch or feel gritty; lids sometimes look sore or crusty. Most of this settles as the eye gets used to the drops. Dorzolamide belongs to the sulfonamide family, and a few people react to it. A spreading rash, swelling of the face or lips, trouble breathing, sudden loss of vision or severe eye pain all need urgent treatment.
Looking after the bottle
Keep it upright with the cap on, out of strong sunlight and away from radiators and hot cars. Do not use the drops past the date on the pack, and do not pass one bottle round the household. The solution should be clear; if it turns cloudy or discoloured, replace it.
