Eylea Side Effects Center

Last reviewed on RxList 8/27/2015

Eylea (aflibercept) is a recombinate protein indicated for the treatment of patients with Neovascular (Wet) Age-Related Macular Degeneration (AMD). AMD is a common cause of blindness. Common side effects of Eylea include burst blood vessel in the eye, eye pain or discomfort after the injection, cataract, watery eyes, blurred vision, swelling of the eyelids, vitreous detachment, eye "floaters," and increased pressure within the eye.

Eylea is supplied as a preservative-free, sterile, aqueous solution in a single-use, glass vial designed to deliver 0.05 mL (50 microliters) of Eylea in the strength of 40 mg/ml. Eylea is injected into the eye either every four weeks or every eight weeks by an ophthalmologist. The recommended dose for Eylea is 2 mg (0.05 mL or 50 microliters) administered by intravitreal injection every 4 weeks(monthly) for the first 12 weeks (3 months), followed by 2 mg(0.05 mL) via intravitreal injection once every 8 weeks (2 months). Eylea should not be used in those who have an active eye infection or active ocular inflammation. Eylea has not been studied in pregnant women, so the treatment should be used only in pregnant women if the potential benefits of the treatment outweigh any potential risks. Age related macular degeneration does not occur in children and Eylea has not been studied in children.

Our Eylea (aflibercept) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Eylea FDA Prescribing Information: Side Effects
(Adverse Reactions)


The following adverse reactions are discussed in greater detail in the Warnings and Precautions (5) section of the labeling:

Clinical Trials Experience

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

A total of 2711 patients treated with EYLEA constituted the safety population in seven phase 3 studies. Among those, 2110 patients were treated with the recommended dose of 2 mg. Serious adverse reactions related to the injection procedure have occurred in < 0.1% of intravitreal injections with EYLEA including endophthalmitis and retinal detachment. The most common adverse reactions ( ≥ 5%) reported in patients receiving EYLEA were conjunctival hemorrhage, eye pain, cataract, vitreous floaters, intraocular pressure increased, and vitreous detachment.

Neovascular (Wet) Age-Related Macular Degeneration (AMD)

The data described below reflect exposure to EYLEA in 1824 patients with wet AMD, including 1223 patients treated with the 2-mg dose, in 2 double-masked, active-controlled clinical studies (VIEW1 and VIEW2) for 12 months [see Clinical Studies].

Table 1: Most Common Adverse Reactions ( ≥ 1%) in Wet AMD Studies

Adverse Reactions EYLEA
Active Control (ranibizumab)
Conjunctival hemorrhage 25% 28%
Eye pain 9% 9%
Cataract 7% 7%
Vitreous detachment 6% 6%
Vitreous floaters 6% 7%
Intraocular pressure increased 5% 7%
Ocular hyperemia 4% 8%
Corneal epithelium defect 4% 5%
Detachment of the retinal pigment epithelium 3% 3%
Injection site pain 3% 3%
Foreign body sensation in eyes 3% 4%
Lacrimation increased 3% 1%
Vision blurred 2% 2%
Intraocular inflammation 2% 3%
Retinal pigment epithelium tear 2% 1%
Injection site hemorrhage 1% 2%
Eyelid edema 1% 2%
Corneal edema 1% 1%

Less common serious adverse reactions reported in < 1% of the patients treated with EYLEA were hypersensitivity, retinal detachment, retinal tear, and endophthalmitis.

Macular Edema Following Retinal Vein Occlusion (RVO)

The data described below reflect 6 months exposure to EYLEA with a monthly 2 mg dose in 218 patients following CRVO in 2 clinical studies (COPERNICUS and GALILEO) and 91 patients following BRVO in one clinical study (VIBRANT) [see Clinical Studies].

Table 2: Most Common Adverse Reactions ( ≥ 1%) in RVO Studies

Adverse Reactions CRVO BRVO
Eye pain 13% 5% 4% 5%
Conjunctival hemorrhage 12% 11% 20% 4%
Intraocular pressure increased 8% 6% 2% 0%
Corneal epithelium defect 5% 4% 2% 0%
Vitreous floaters 5% 1% 1% 0%

Intraocular inflammation 1% 1% 0% 0%
Cataract < 1% 1% 5% 0%
Eyelid edema < 1% 1% 1% 0%

Less common adverse reactions reported in < 1% of the patients treated with EYLEA in the CRVO studies were corneal edema, retinal tear, hypersensitivity, and endophthalmitis.

Diabetic Macular Edema (DME)

The data described below reflect exposure to EYLEA in 578 patients with DME treated with the 2-mg dose in 2 double-masked, controlled clinical studies (VIVID and VISTA) from baseline to week 52 and from baseline to week 100 [see Clinical Studies].

Table 3: Most Common Adverse Reactions ( ≥ 1%) in DME Studies

Adverse Reactions Baseline to Week 52 Baseline to Week 100
Conjunctival hemorrhage 28% 17% 31% 21%

Vitreous floaters 6% 3% 8% 6%
Corneal epithelium defect 5% 3% 7% 5%
Intraocular pressure increased 5% 3% 9% 5%

Injection site pain 2% < 1% 2% < 1%
Eyelid edema < 1% 1% 2% 1%

Less common adverse reactions reported in < 1% of the patients treated with EYLEA were hypersensitivity, retinal detachment, retinal tear, corneal edema, and injection site hemorrhage.


As with all therapeutic proteins, there is a potential for an immune response in patients treated with EYLEA. The immunogenicity of EYLEA was evaluated in serum samples. The immunogenicity data reflect the percentage of patients whose test results were considered positive for antibodies to EYLEA in immunoassays. The detection of an immune response is highly dependent on the sensitivity and specificity of the assays used, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to EYLEA with the incidence of antibodies to other products may be misleading.

In the wet AMD, RVO, and DME studies, the pre-treatment incidence of immunoreactivity to EYLEA was approximately 1% to 3% across treatment groups. After dosing with EYLEA for 24-100 weeks, antibodies to EYLEA were detected in a similar percentage range of patients. There were no differences in efficacy or safety between patients with or without immunoreactivity.
