What should a patient do if they experience a headache and intense eye pain after using latanoprost?

In cases where a patient experiences a headache and intense eye pain after using latanoprost, it is important to prioritize immediate medical evaluation. These symptoms could indicate a serious and potentially harmful reaction to the medication, such as increased intraocular pressure or other acute complications that require prompt attention.

Seeking immediate care allows healthcare professionals to assess the patient's condition, provide necessary interventions, and ensure that no serious underlying issues are present. Acting quickly is critical, as delays in addressing severe symptoms can lead to more significant complications, especially in the context of eye health. Therefore, encouraging the patient to go to the clinic or emergency department is the most appropriate and safe course of action in response to these concerning symptoms.
