Alrex is a prescription medication indicated to alleviate excessive eye swelling caused by certain conditions, including infection, allergies or surgery. This medication is administered directly to the affected eye as liquid drops, and should not be used for longer than 14 days unless otherwise prescribed by a doctor, Drugs.com warns. Patients should be aware of Alrex side effects before receiving treatment with this medication.
Eye Irritation
During clinical trials for this medication, between 5 and 15 percent of patients reported experience some type of eye or ocular adverse reactions, according to the U.S. Food and Drug Administration. While receiving treatment with Alrex, patients may experience eye irritation, which may manifest as red, itchy, dry or watery eyes. Certain patients may experience a mild burning sensation upon application of the liquid drops into the eye. Use of this medication may also cause patients to feel like something is in the treated eye, a side effect referred to as a foreign body sensation. Affected patients may frequently rub or scratch the affected eye, which may exacerbate eye irritation. Patients should consult a medical professional if these side effects persist or become worse.
Increased Sensitivity to Light
RxList reports that Alrex patients may notice that they are more sensitive to light, a side effect called photophobia. Increased light sensitivity may cause patients to frequently squint or shield their eyes while in a bright or light-filled environment. Certain patients may also experience blurred or cloudy vision in conjunction with increased light sensitivity. Though these side effects generally resolve, they may persist for the duration of treatment.
Nasal Congestion, Sore Throat or Headache
Alrex may cause additional side effects in treated patients, including nasal congestion, sore throat or headache, Drugs.com warns. Nasal congestion may require patients to frequently blow their nose to clear mucus from their nasal passages. Sore throat symptoms can cause difficulty or painful swallowing, which may negatively impact a patient's normal appetite. Headache pain may be exacerbated by ocular side effects, such as blurred vision, and can disrupt a patient's ability to concentrate or focus during daily activities.
