Does Eylea interact with other medications? Learn about Eylea drug interactions, what to tell your doctor, and precautions for blood thinners and more.
If you're taking Eylea (aflibercept) for wet AMD, diabetic macular edema, or another retinal condition, you might be wondering whether it interacts with your other medications. It's a smart question, especially if you take several prescriptions.
The good news: because Eylea is injected directly into the eye (not taken orally or through an IV), it has minimal systemic drug interactions. Very little of the medication reaches the rest of your body, which means it's unlikely to interfere with most other drugs you take.
That said, there are still some important things to know and share with your doctor.
Most drug interactions happen when two medications are absorbed into the bloodstream and compete for the same enzymes, receptors, or metabolic pathways. Oral medications and IV drugs are most likely to cause these types of interactions because they circulate throughout the entire body.
Eylea is different. It's an intravitreal injection — delivered directly into the vitreous gel inside the eye. The amount of aflibercept that enters the general circulation is extremely small. This local delivery means Eylea doesn't significantly interact with medications processed by your liver, kidneys, or other organs.
For more on how Eylea works inside the eye, see our guide on Eylea's mechanism of action.
While Eylea doesn't have established drug-drug interactions, there are some medication categories worth discussing before your injection.
This is the most important category to be aware of. If you take blood thinners, the injection procedure itself (not Eylea the drug) may carry a slightly higher risk of bleeding at the injection site or inside the eye.
Common blood thinners include:
In most cases, your doctor will not ask you to stop your blood thinner before an Eylea injection. The risk of stopping an anticoagulant (stroke, blood clot) usually outweighs the small risk of eye bleeding. However, your doctor should know you're taking one so they can monitor accordingly.
The most common result of blood thinner use during injection is conjunctival hemorrhage — a red spot on the white of the eye that looks alarming but is harmless and resolves on its own.
If you're receiving Eylea, you generally should not be receiving another anti-VEGF injection (like Lucentis, Avastin, or Vabysmo) in the same eye at the same time. These medications work through similar pathways, and combining them in the same eye has not been shown to provide additional benefit and could increase risk.
However, if you're being treated in both eyes, your doctor may use different anti-VEGF medications in each eye based on the specific condition and response. This is a decision made by your retina specialist.
Some patients with macular edema receive intravitreal steroid injections (like Ozurdex or triamcinolone) in addition to or instead of anti-VEGF treatment. If your doctor is considering combining steroid and anti-VEGF injections, they'll manage the timing and monitor for increased eye pressure, which both types of treatment can cause.
Many patients with AMD take the AREDS2 vitamin formula (containing vitamins C, E, zinc, copper, lutein, and zeaxanthin). These supplements do not interact with Eylea and can be taken safely alongside it. In fact, your doctor may recommend them as a complement to your Eylea treatment.
Non-steroidal anti-inflammatory drugs like ibuprofen (Advil) and naproxen (Aleve) can thin the blood slightly and may increase the risk of bleeding at the injection site. This isn't a drug interaction with Eylea itself, but your doctor may suggest using acetaminophen (Tylenol) instead for pain relief around the time of your injection.
High-dose fish oil can have mild blood-thinning effects. While this is unlikely to cause problems, mention it to your doctor if you take fish oil supplements regularly.
Some herbal supplements can affect bleeding risk, including:
These are not direct interactions with Eylea, but they may increase the risk of bleeding during the injection procedure.
There are no food or drink interactions with Eylea. You don't need to fast before your injection or avoid any particular foods.
Some practical tips for injection day:
Even though Eylea has minimal drug interactions, you should always give your retina specialist a complete picture of what you're taking. Before your first injection (and whenever your medications change), tell your doctor about:
Also inform your doctor if you have any active eye infections or inflammation, as these are contraindications for Eylea.
This is extremely unlikely. Because Eylea is administered locally in the eye and very little reaches the bloodstream, it is not expected to affect the way other medications work in your body. There are no known cases of Eylea reducing the effectiveness of other drugs or increasing their side effects.
Eylea has one of the cleanest drug interaction profiles of any medication, thanks to its local route of administration. The main precaution is around blood thinners and the injection procedure itself — not the drug's interaction with other medications.
Still, always keep your doctor informed about everything you're taking. It's the best way to ensure your treatment is as safe and effective as possible.
