Found a white oval pill i 8 in the bottom of a bag? Or maybe you just got a new prescription and the imprint looks a bit unfamiliar. It happens constantly. You'd think identifying a medication would be straightforward, but with thousands of generic manufacturers cranking out lookalike tablets, it’s actually a bit of a minefield.
The "i 8" imprint is a very specific identifier. It isn't just a random serial number; it's a fingerprint. If you have a white, oval-shaped tablet with "i 8" on one side, you are likely looking at Ibuprofen 800 mg. This is a high-dose, prescription-strength Non-Steroidal Anti-Inflammatory Drug (NSAID).

Most people know Ibuprofen as Advil or Motrin. But those over-the-counter (OTC) versions usually cap out at 200 mg. When you see that "i 8," you're holding four times the strength of a standard drugstore pill. It’s serious stuff. It’s primarily manufactured by Granules India, a massive pharmaceutical player that supplies a huge chunk of the world's generic ibuprofen.
What Exactly is the White Oval Pill i 8?
Basically, this pill is a heavy hitter for pain and inflammation. Doctors don't just hand these out for a mild headache. If you’ve been prescribed this, it’s usually because your body is dealing with something more structural or chronic.
Think rheumatoid arthritis or osteoarthritis. We’re talking about the kind of joint pain that makes getting out of bed feel like a chore. It’s also frequently prescribed for severe menstrual cramps (dysmenorrhea) or acute musculoskeletal injuries—like if you really blew out your back moving a couch.
The "i" stands for the manufacturer, Granules India, and the "8" corresponds to the 800 milligrams of active ingredient. The pill is film-coated, which helps it slide down a bit easier, but let’s be real: it’s a big pill. Some people call them "horse pills" for a reason.
Is it different from OTC Advil?
Yes and no. The chemical—Ibuprofen—is identical. However, the dosage is the gatekeeper. You cannot buy 800 mg tablets over the counter in the United States. The FDA regulates this because taking 800 mg at once increases the risk profile significantly compared to the 200 mg or 400 mg doses people self-administer for a tension headache.

Why the Imprint i 8 Matters for Safety
Pill identification isn't just about curiosity. It's about staying alive.
There are plenty of white oval pills out there. Some are Gabapentin. Some are Metformin. Some are even powerful opioids like Hydrocodone (though those usually have very different imprints). If you mistake an NSAID for something else—or vice versa—the results can be messy.
If you have a "white oval pill i 8" and you aren't the one it was prescribed to, stop. Don't take it. Even though it's "just ibuprofen," 800 mg can be dangerous for people with certain underlying conditions.
The Kidney and Stomach Factor
NSAIDs work by blocking COX-1 and COX-2 enzymes. This reduces prostaglandins, which are the chemicals that signal pain. But prostaglandins also protect your stomach lining and keep blood flowing to your kidneys. When you take a high dose like the i 8 pill, you're putting a lot of stress on those systems.
People with a history of stomach ulcers or "leaky gut" issues need to be incredibly careful. One 800 mg pill can be enough to trigger a GI bleed in vulnerable individuals. Same goes for your kidneys. If you’re dehydrated or have stage 2 or 3 kidney disease, this pill is basically off-limits unless a nephrologist says otherwise.
Common Side Effects You Might Experience
Honestly, most people tolerate Ibuprofen 800 mg okay if they take it with food. But "okay" is relative.
- Heartburn: This is the big one. It feels like a slow burn in your chest.
- Nausea: Taking this on an empty stomach is a rookie mistake. Always eat something.
- Dizziness: Sometimes high-dose NSAIDs can make the world feel a little tilt-a-wheel.
- Ringing in the ears: Known as tinnitus. If you start hearing a high-pitched buzz after taking an i 8 pill, that's a sign your dose might be too high.
Then there are the "red flag" symptoms. If you notice black, tarry stools or a "coffee ground" appearance in vomit, that’s an emergency. That’s blood. It means the medication has irritated the stomach lining to the point of bleeding. It sounds scary because it is.
Interactions: What Not to Mix with i 8
The white oval pill i 8 doesn't play well with others. Specifically, it hates blood thinners.
If you’re on Warfarin or Eliquis, adding an 800 mg Ibuprofen is like begging for a bleeding event. It also interferes with certain blood pressure medications, particularly ACE inhibitors like Lisinopril. It can actually make your blood pressure meds less effective, which is a weird side effect that most people don't realize.
Also, watch out for the "double-up." Many multi-symptom cold and flu medicines contain ibuprofen. If you take one of those along with an i 8 pill, you’re creeping into the danger zone of daily limits. The absolute maximum for an adult is typically 3200 mg in 24 hours, but you really don't want to live at that limit for long.
How to Verify Your Pill
Don't just take my word for it. If you find a pill, verify it through multiple points of data.
- Check the Imprint: Look closely under a bright light. Is it "i 8" or maybe "L8"? (L8 is different).
- Size and Shape: The Granules India i 8 is an oval, white, film-coated tablet.
- The "Scribe" Line: Does it have a score mark? The standard i 8 usually does not have a deep score for splitting, as it's intended to be taken whole.
- Professional Confirmation: Take the pill to any local CVS, Walgreens, or independent pharmacist. They have access to the Lexicomp or Micromedex databases which are far more reliable than a random image search.
Practical Steps if You Have This Pill
If you’ve identified your medication as the white oval pill i 8 (Ibuprofen 800 mg), here is how to handle it responsibly.
Always take it with a full meal. A few crackers aren't enough. You want a "cushion" in your stomach to prevent the acid-blocking properties of the drug from eroding your gastric lining.
Watch your hydration. Your kidneys need water to process this dosage. If you're out hiking in 90-degree heat and popping 800 mg of ibuprofen, you're asking for acute kidney injury.
Limit the duration. This isn't a "forever" drug. If you're still in enough pain to need an i 8 pill after 10 days, you need a different treatment plan. Chronic use of high-dose NSAIDs is one of the leading causes of avoidable kidney failure and cardiovascular issues like heart attacks or strokes in older adults.
Audit your cabinet. If you find an old bottle and the pills are expired, toss them. While ibuprofen doesn't usually become "toxic" immediately after the expiration date, it loses potency and the binders in the pill can start to break down, making it harder on your stomach.
If you are unsure about whether this medication is right for your specific health history, call your primary care provider. It is much better to ask a "silly" question than to deal with a GI bleed because you took a pill you found in a kitchen drawer.
Keep the medication in its original container. If you must use a pill organizer, ensure it’s labeled clearly so you don't confuse this high-dose NSAID with a supplement or a different prescription.
