Key takeaways
Latanoprost (Xalatan) and Alphagan P (brimonidine) are both prescription eye drops used to lower eye pressure in conditions like glaucoma and ocular hypertension, but they work differently and have distinct usage patterns. Latanoprost is a prostaglandin that helps fluid drain from the eye and is typically used once daily in the evening. In contrast, Alphagan P is an alpha-2 agonist that reduces fluid production in the eye and is applied three times a day. Latanoprost can cause changes in eye color and eyelash growth, while Alphagan P is more likely to cause dry mouth, headaches, and drowsiness. Latanoprost needs refrigeration before opening, whereas Alphagan P can be stored at room temperature. Both medications require the removal of contact lenses before use, but latanoprost is known for causing less eye irritation compared to Alphagan P.
