Adverse events referred to in other sections: Eyelash changes (increased length, thickness, pigmentation, and number of lashes); eyelid skin darkening; intraocular inflammation (iritis/uveitis); iris pigmentation changes; and macular edema, including cystoid macular edema (see Warnings and Precautions).
Controlled Clinical Trials: The ocular adverse events and ocular signs and symptoms reported in 5 to 15% of the patients on latanoprost ophthalmic eye drops in the three 6-month, multi-center, double-masked, active controlled trials were blurred vision, burning and stinging, conjunctival hyperemia, foreign body sensation, itching, increased pigmentation of the iris, and punctuate epithelial keratopathy.
Local conjunctival hyperemia was observed; however, less than 1% of the patients treated with latanoprost required discontinuation of therapy because of intolerance to conjunctival hyperemia.
In addition to the previously listed ocular events/signs and symptoms, the following were reported in 1 to 4% of the patients: Dry eye, excessive tearing, eye pain, lid crusting, lid discomfort/pain, lid edema, lid erythema, and photophobia.
The following events were reported in less than 1% of the patients: Conjunctivitis, diplopia and discharge from the eye.
During clinical studies, there were extremely rare reports of the following: Retinal artery embolus, retinal detachment, and vitreous hemorrhage from diabetic retinopathy.
The most common systemic adverse events seen with Latanoprost were upper respiratory tract infection/cold/flu, which occurred at a rate of approximately 4%. Chest pain/angina pectoris, muscle/joint/back pain, and rash/allergic skin reaction each occurred at a rate of 1 to 2%.
Clinical Practice: The following events have been identified during postmarketing use of Latanoprost in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The events, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to Latanoprost, or a combination of these factors, include: Asthma and exacerbation of asthma; corneal edema and erosions; dyspnea; eyelash and vellus hair changes (increased length, thickness, pigmentation, and number); eyelid skin darkening; herpes keratitis; intraocular inflammation (iritis/uveitis); keratitis; macular edema, including cystoid macular edema; misdirected eyelashes sometimes resulting in eye irritation; dizziness, headache, and toxic epidermal necrolysis; periorbital and lid changes resulting in deepening of the eyelid sulcus.
