If you experience any of the following serious side effects, stop using phenylephrine ophthalmic and seek emergency medical attention or contact your doctor immediately:

an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, face, or tongue; or hives);

an irregular or fast heart rate; or

high blood pressure (severe headache, blurred vision, or flushed skin).

Other, less serious side effects may be more likely to occur. Continue to use phenylephrine ophthalmic and talk to your doctor if you experience

burning, stinging, pain, or increased redness of the eye;

tearing or blurred vision;

headache;

tremor;

nausea;

sweating;

nervousness;

dizziness; or

drowsiness.

Symptoms of allergic or infusion reactions including difficulty breathing; closing of the throat; hives; rash; itching; fever; shaking; chest tightness; high or low blood pressure; fast heartbeats; muscle pain; stomach pain; nausea or vomiting; dizziness; numbness or tingling; and headache have occurred upon injection of agalsidase beta in many patients. Most patients treated with agalsidase beta develop antibodies to agalsidase beta and many will develop symptoms of an infusion reaction. A slow rate of injection of the medication and pretreatment with other medications may decrease the severity of these symptoms. Emergency medical attention may be required if a severe allergic reaction is experienced.
