Tropicamide is a medication primarily used in eye care as a mydriatic agent, which means it helps to dilate the pupils. It is often administered during eye examinations to allow doctors to get a better view of the interior structures of the eye. Tropicamide works by blocking certain receptors in the eye, leading to relaxation of the muscles that constrict the pupil. The effects of tropicamide typically begin within 20 to 30 minutes after application and can last for several hours. While it is generally safe, some individuals may experience side effects such as blurred vision or sensitivity to light. It is important to follow the guidance of a healthcare professional when using this medication.
