Ryzumvi (phentolamine) is an eye drop used for pharmacologically-induced mydriasis, or more simply, it is used to reverse dilated pupils caused by eye drops used during eye examinations for routine eye check-ups, disease monitoring, or surgical procedures.
Dilated pupils cause sensitivity to light (photophobia) and blurred vision, which may make it difficult to read, work, and drive, which can last 24 hours after the examination. Ryzumvi eye drops are used to speed up the return to normal pupil size, to restore normal vision, and reduce light sensitivity so there is less disruption to daily activities.
