Latanoprost is a medication primarily used to treat increased pressure in the eyes, commonly associated with conditions like glaucoma and ocular hypertension. It works by increasing the outflow of fluid from the eye, which helps to lower intraocular pressure and protect vision. Typically administered as an eye drop, Latanoprost is often prescribed once daily in the evening. Common side effects may include eye redness, changes in eyelash growth, and darkening of the iris. Regular monitoring by an eye care professional is essential to ensure the medication is effective and to manage any potential side effects.
