Introduction About SYNCA LS EYE DROPS
SYNCA LS EYE DROPS is indicated for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. It is typically used in patients who are not responding well to therapy with single agents. It is a combination of Brimonidine and brinzolamide, which belongs to the group of medicines called Ophthalmic anti-glaucoma agents. It works by decreasing the production of excessive eye fluids (aqueous humour) while simultaneously increasing their drainage. As a result, it reduces strain on the eyes, which therefore reduces elevated intraocular pressure.
SYNCA LS EYE DROPS is for ophthalmic use only. Instill a few drops of this medicine into the affected eye(s). Do not touch the tip of the dropper with your eye or with other body surfaces to avoid contamination. If you wear soft contact lenses, remove the lens before using SYNCA LS EYE DROPS and wait for at least 15 minutes before reinsertion.
Before using SYNCA LS EYE DROPS, inform your doctor if you have any liver, kidney, or heart problems. You must also inform your doctor if you have low or high blood pressure, narrow-angle glaucoma, dry eyes, depression, or poor blood circulation in your body as a precaution.
SYNCA LS EYE DROPS is generally not recommended for use in pregnant and breastfeeding women unless considered necessary by the physician. Therefore, consult your doctor before using it. The most common side effects of using SYNCA LS EYE DROPS are eye pain, redness, discomfort, irritation, itching or inflammation, blurred vision, and bad taste. Consult your doctor if they trouble you.
