Learn about important Orapred drug interactions, including NSAIDs, blood thinners, diabetes meds, and more. Know what to avoid and what to tell your doctor.
Orapred (Prednisolone Sodium Phosphate) is a corticosteroid that affects multiple systems in your body. While it's highly effective at reducing inflammation and suppressing immune responses, those same broad effects mean it can interact with a surprising number of other medications, supplements, and even foods.
If you're not familiar with Orapred, start with our overview of what Orapred is and how it's used. This article focuses specifically on drug interactions — what to watch out for, what to avoid, and what to tell your doctor before starting treatment.
These interactions can have serious clinical consequences and should always be discussed with your doctor.
Taking Orapred with nonsteroidal anti-inflammatory drugs (NSAIDs) like Ibuprofen (Advil, Motrin), Naproxen (Aleve), or Aspirin significantly increases the risk of:
Both corticosteroids and NSAIDs irritate the stomach lining independently — together, the risk multiplies. If you need pain relief while taking Orapred, ask your doctor about Acetaminophen (Tylenol) instead, which doesn't carry the same GI risk.
Orapred can alter the effectiveness of Warfarin and other anticoagulants, either increasing or decreasing their blood-thinning effect. This can lead to either increased bleeding risk or reduced protection against blood clots. If you take a blood thinner, your doctor should monitor your INR (blood clotting levels) more frequently while you're on Orapred.
Orapred at immunosuppressive doses suppresses your immune system's ability to respond to vaccines — and with live vaccines, it can be dangerous. Do not receive live or live-attenuated vaccines while taking immunosuppressive doses of Orapred. Examples include:
Inactivated vaccines (like the flu shot or COVID-19 vaccines) are generally safe but may be less effective while you're on Orapred.
Prednisolone is partially metabolized by the CYP3A4 enzyme in the liver. Drugs that inhibit this enzyme can increase Prednisolone levels in your blood, intensifying both its effects and side effects. Common CYP3A4 inhibitors include:
If you take any of these, your doctor may need to lower your Orapred dose.
On the flip side, drugs that speed up CYP3A4 can decrease Prednisolone levels, making Orapred less effective. Common inducers include:
If you take one of these medications, your doctor may need to increase the Orapred dose to achieve the desired effect.
Corticosteroids like Orapred raise blood sugar — sometimes significantly. This can counteract the effects of diabetes medications, including:
If you have diabetes, monitor your blood sugar closely while on Orapred and work with your doctor to adjust your diabetes medication if needed.
These are worth knowing about, though they're usually manageable with monitoring.
Both Orapred and diuretics like Furosemide (Lasix) or Hydrochlorothiazide can cause potassium loss. Together, the risk of hypokalemia (dangerously low potassium) increases. Symptoms include muscle weakness, cramps, and heart rhythm changes. Your doctor may check your potassium levels or recommend a potassium supplement.
Antibiotics like Ciprofloxacin (Cipro) and Levofloxacin (Levaquin) already carry a risk of tendon rupture. Combining them with corticosteroids like Orapred increases this risk further, particularly in patients over 60. Report any tendon pain, swelling, or stiffness immediately.
Orapred and Cyclosporine (an immunosuppressant) can increase each other's blood levels, raising the risk of side effects from both medications. This combination is sometimes used intentionally in transplant medicine, but requires careful monitoring.
Even low-dose Aspirin (81 mg for heart protection) can interact with Orapred. Corticosteroids may increase the clearance of Aspirin, potentially reducing its cardiovascular protective effect. They also compound GI bleeding risk. Discuss this with your cardiologist and prescriber.
Grapefruit inhibits CYP3A4, which can increase Prednisolone levels in your blood. While the effect is generally modest, it's worth avoiding large amounts of grapefruit or grapefruit juice while taking Orapred.
Alcohol irritates the stomach lining, and so does Orapred. Together, they increase the risk of gastritis, ulcers, and GI bleeding. It's best to avoid alcohol or limit it to minimal amounts while taking Orapred.
Corticosteroids promote sodium and water retention. A high-sodium diet can worsen fluid retention, bloating, and blood pressure elevation. Try to reduce salt intake while on Orapred.
Before your doctor prescribes Orapred, make sure they have a complete picture:

Orapred interacts with a wide range of medications — from common painkillers to diabetes drugs to antibiotics. Most interactions are manageable when your doctor knows about them in advance. The key is transparency: always share your complete medication list before starting Orapred.
