Izba FDA Prescribing Information: Side Effects
(Adverse Reactions)


Clinical Studies Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.

Different methodologies were used to collect adverse reactions during the development of travoprost. The most common adverse reaction observed in controlled clinical studies with travoprost 0.004% was ocular hyperemia. Ocular hyperemia was reported in 30 to 50% of patients by physician rating the severity of patient's post treatment ocular hyperemia compared to standardized reference photographs and/or patients who discontinued therapy due to ocular hyperemia.

In a 3 month clinical trial involving 442 patients exposed to IZBA (travoprost ophthalmic solution, 0.003%) and 422 control patients exposed to travoprost ophthalmic solution, 0.004%, the most common adverse drug reaction was ocular hyperemia. This was reported in 12% of patients treated with IZBA based on clinical observations and/or patient complaints. One patient (0.2%) discontinued treatment with IZBA due to ocular hyperemia. Rates observed in the control patients were comparable.

Ocular adverse reactions reported in clinical studies with travoprost ophthalmic solutions including IZBA at an incidence of 5% to 10% included decreased visual acuity, eye discomfort, foreign body sensation, pain and pruritus. Ocular adverse reactions reported at an incidence of 1 to 4% included abnormal vision, blepharitis, blurred vision, cataract, conjunctivitis, corneal staining, dry eye, iris discoloration, keratitis, lid margin crusting, ocular inflammation, photophobia, subconjunctival hemorrhage and tearing.

Nonocular adverse reactions reported at an incidence of 1 to 5% in these clinical studies were allergy, angina pectoris, anxiety, arthritis, back pain, bradycardia, bronchitis, chest pain, cold/flu syndrome, depression, dyspepsia, gastrointestinal disorder, headache, hypercholesterolemia, hypertension, hypotension, infection, pain, prostate disorder, sinusitis, urinary incontinence and urinary tract infections.

In postmarketing use with prostaglandin analogs, periorbital and lid changes including deepening of the eyelid sulcus have been observed.
