Frequency not defined. Severity and frequency of adverse reactions are dose related.
Cardiovascular: Delirium, flushing, hypotension, increased blood pressure
Central nervous system: Irritability, restlessness

Gastrointestinal: Xerostomia
Ophthalmic: Blurred vision, decreased lacrimation, eye irritation, eyelid edema, eye pain, papillary conjunctivitis, photophobia, stinging of eyes, superficial keratitis
Respiratory: Dry throat, respiratory depression
Concerns related to adverse effects:
- Elevated blood pressure: May occur due to systemic absorption following conjunctival instillation.
- Photophobia/blurred vision: May last up to 2 weeks due to pupil unresponsiveness and cycloplegia.

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience blurred vision or stinging. Have patient report immediately to prescriber severe headache, dizziness, passing out, vision changes, tachycardia, abnormal heartbeat, flushing, irritability, agitation, dry mouth, dry skin, severe eye irritation, or eye pain (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
