Omidria (phenylephrine and ketorolac) Injection is a combination alpha 1-adrenergic receptor agonist and a nonsteroidal anti-inflammatory drug (NSAID) that is added to an ophthalmic irrigation solution used during cataract surgery or intraocular lens replacement and is used for maintaining pupil size by preventing intraoperative miosis and reducing postoperative ocular pain. Common side effects of Omidria include eye inflammation, increased ocular pressure, eye irritation, the feeling of a foreign body being in the eye, sensitivity of eyes to light, sores in the eye, or allergic reactions such as skin rash, swelling of the face, lips, or tongue.

For administration to patients undergoing cataract surgery or intraocular lens replacement, a dose of 4 mL of Omidria is diluted in 500 mL of ophthalmic irrigation solution. Omidria may interact with other drugs. Tell your doctor all medications and supplements you use. During pregnancy, Omidria should only be administered if necessary. Consult your doctor before breastfeeding.

Our Omidria (phenylephrine and ketorolac) Injection Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
