What is TRUSOPT Preservative-Free 20 mg/ml eye drops?
TRUSOPT Preservative-Free 20 mg/ml eye drops contain dorzolamide hydrochloride, a carbonic anhydrase inhibitor. It is used to help lower intraocular pressure in people with glaucoma or ocular hypertension.
This version is preservative-free and supplied in single-dose containers. That format may be helpful for patients who are sensitive to preservatives or who find some eye drops irritating.
TRUSOPT is a prescription medicine. The exact use, suitability, and dosing should be confirmed by a healthcare professional.
How does TRUSOPT work?
TRUSOPT works by inhibiting the enzyme carbonic anhydrase. This helps reduce the production of aqueous humor, the fluid inside the eye.
By lowering fluid production, the medicine can help reduce intraocular pressure, which is an important part of managing glaucoma and ocular hypertension.
It may be used on its own or alongside other eye medicines, depending on the treatment plan set by the clinician.
How is it usually used?
The current content states that patients are often instructed to use one drop in the affected eye(s) three times daily. However, the exact schedule can vary, so the prescribed directions and the patient leaflet should always be followed.
| Use point | What to check |
|---|---|
| Dose schedule | Follow the prescription and leaflet instructions. |
| Application | Wash hands first and avoid touching the container tip. |
| After instilling | Close the eye and press the inner corner briefly to reduce drainage. |
| Missed dose | Check the leaflet or ask a pharmacist for the correct advice. |

Is TRUSOPT safe in pregnancy or breastfeeding?
The original content says safety in pregnancy and breastfeeding has not been fully established. It also notes that the benefits and risks should be weighed carefully with a healthcare provider.
If you are pregnant, planning a pregnancy, or breastfeeding, the safest next step is to review the medicine with your clinician or pharmacist and check the official leaflet for the most current guidance.
