Last Updated: August 20, 2026
The BI 8 White Pill is identified in current U.S. drug labeling as ibuprofen 800 mg, a prescription-strength nonsteroidal anti-inflammatory drug, or NSAID. The tablet is white, capsule-shaped, approximately 19 mm long, and marked BI 8. Current product information lists it as an unscored tablet.
Ibuprofen is commonly used to relieve pain and inflammation, but an 800 mg tablet is substantially stronger than the standard 200 mg ibuprofen tablets sold over the counter. Prescription-strength ibuprofen can also cause serious adverse effects, including gastrointestinal bleeding, kidney injury, cardiovascular events, elevated blood pressure, severe skin reactions, and drug interactions.
Understanding what the BI 8 White Pill contains, why it may be prescribed, and when it can become dangerous is therefore important before taking it.
Key Takeaways
- The BI 8 White Pill is ibuprofen 800 mg
- It is a prescription-strength NSAID
- The 800 mg strength does not mean everyone should take that dose
- Use the lowest effective dose for the shortest necessary time
- Serious risks include stomach bleeding, kidney problems, heart events, and liver issues
- Ibuprofen can interact with aspirin, anticoagulants, other NSAIDs, and some blood-pressure medicines
- Extra caution is needed during pregnancy, especially from 20 weeks onward
- Long-term use may require medical monitoring
- Unidentified pills should be confirmed by a pharmacist before use
What Does the BI 8 Imprint Mean?
Medication manufacturers use letters, numbers, and other markings to help identify tablets.
For this medication:
- BI 8 identifies the 800 mg ibuprofen tablet in the relevant product family
- BI 6 identifies an ibuprofen 600 mg tablet
- BI 4 identifies an ibuprofen 400 mg tablet
Current DailyMed labeling lists the three strengths together.
The imprint is particularly useful when distinguishing prescription-strength ibuprofen tablets that otherwise look similar.
However, pill identification should never rely on an imprint alone if the tablet came from an uncertain source. Counterfeit drugs can imitate legitimate markings.
Who Manufactures the BI 8 White Pill?
One current DailyMed product listing identifies the underlying BI 8 ibuprofen 800 mg tablet as manufactured by Shandong Xinhua Pharmaceutical Co., Ltd.
A current listing associated with Westminster Pharmaceuticals uses source NDC 69367-396 for the 800 mg product, including:
- 69367-396-01 for certain 100-tablet packaging
- 69367-396-05 for certain 500-tablet packaging
DailyMed also shows BI 8 tablets being repackaged and relabeled by other pharmaceutical companies.
This explains why two legitimate bottles containing the same BI 8 tablet may display different NDC numbers or labeler names.
Why BI 8 NDC Numbers Can Differ
An NDC identifies a particular drug product and packaging configuration.
The tablet can move through several stages:
Manufacturer → distributor or labeler → repackager → pharmacy → patient
Therefore, searching for one universal BI 8 NDC number may cause confusion.
The tablet’s:
- Active ingredient
- Strength
- Imprint
- Shape
may remain the same even when its package NDC changes.
What Ingredients Are in the BI 8 White Pill?
The active ingredient is:
Ibuprofen 800 mg
One current DailyMed BI 8 listing includes inactive ingredients such as:
- Microcrystalline cellulose
- Silicon dioxide
- Croscarmellose sodium
- Magnesium stearate
- Corn starch
- Polyethylene glycol
- Sodium starch glycolate
- Stearic acid
- Talc
- Titanium dioxide
Inactive ingredients may vary among manufacturers, labelers, or repackagers.
If you have a known medication, dye, or excipient allergy, check the labeling on your specific prescription or ask the dispensing pharmacist instead of relying exclusively on an online ingredient list.
What Is Ibuprofen?
Ibuprofen belongs to the family of medications known as nonsteroidal anti-inflammatory drugs.
NSAIDs reduce the body’s production of prostaglandins, chemical messengers involved in:
- Pain
- Inflammation
- Fever
- Blood-vessel regulation
- Stomach protection
- Kidney blood flow
Reducing prostaglandin activity can relieve pain and inflammation.
The same mechanism helps explain some NSAID risks. Prostaglandins also perform protective functions in the stomach, kidneys, and cardiovascular system, so excessive or prolonged suppression can contribute to adverse effects.
What Is the BI 8 White Pill Used For?
Prescription ibuprofen labeling includes use for:
- Rheumatoid arthritis
- Osteoarthritis
- Mild-to-moderate pain
- Primary dysmenorrhea, or menstrual cramps
Rheumatoid Arthritis
Rheumatoid arthritis is an inflammatory autoimmune disease that can cause:
- Joint swelling
- Pain
- Stiffness
- Reduced movement
Ibuprofen may reduce pain and inflammation, although it does not treat the underlying autoimmune cause or prevent disease progression.
Osteoarthritis
Osteoarthritis involves progressive deterioration of joint cartilage and surrounding structures.
Prescription NSAIDs may help reduce:
- Joint pain
- Stiffness
- Inflammatory discomfort
They do not rebuild damaged cartilage.
Mild-to-Moderate Pain
Ibuprofen may be prescribed for certain forms of acute pain.
Examples may include pain related to:
- Musculoskeletal injuries
- Inflammation
- Dental procedures
- Other conditions where a clinician considers an NSAID appropriate
Importantly, an 800 mg tablet does not automatically mean an 800 mg dose is necessary for acute pain.
Menstrual Cramps
Ibuprofen can help primary dysmenorrhea because prostaglandins contribute to the uterine contractions and inflammation responsible for menstrual cramps.
Is BI 8 a Narcotic or Opioid?
No.
The BI 8 White Pill is not:
- Oxycodone
- Hydrocodone
- Morphine
- Codeine
- Another opioid medication
Ibuprofen works primarily by affecting prostaglandin production rather than opioid receptors.
Is the BI 8 White Pill a Controlled Substance?
No.
Ibuprofen is not federally scheduled as a controlled substance in the United States.
It does not carry the same addiction or dependence profile as opioid pain medications.
However, being non-controlled does not mean it is harmless. Serious toxicity can still occur from inappropriate doses, prolonged use, drug interactions, or overdose.
How Strong Is an 800 mg Ibuprofen Tablet?
The BI 8 White Pill contains 800 mg of ibuprofen, making it one of the commonly manufactured high-strength prescription ibuprofen tablets.
For comparison:
- 1 standard OTC tablet = 200 mg
- BI 4 = 400 mg
- BI 6 = 600 mg
- BI 8 = 800 mg
The key distinction is:
Tablet strength does not equal the correct dose for every situation.
An 800 mg tablet tells you how much ibuprofen is inside. It does not establish:
- How much you personally need
- How frequently you should take it
- How long treatment should continue
- Whether your kidneys can safely tolerate it
- Whether it interacts with another medication
- Whether another treatment would be safer
How Long Does the BI 8 White Pill Take to Work?

Oral ibuprofen is rapidly absorbed.
Current prescription labeling reports that peak serum ibuprofen concentrations are generally reached within one to two hours after administration. The serum half-life is approximately 1.8 to 2 hours.
Food can reduce the rate of absorption when ibuprofen is taken immediately after a meal, but labeling indicates that it does not substantially reduce the overall amount absorbed.
It is important not to confuse these pharmacokinetic measurements with an exact pain-relief timeline.
Peak blood concentration does not mean everyone will begin feeling relief at precisely the same time.
The perceived effect can depend on:
- Condition being treated
- Severity of inflammation
- Dose prescribed
- Whether food was consumed
- Individual metabolism
- Other medications
- Duration of treatment
For chronic inflammatory conditions such as arthritis, full therapeutic improvement may also take longer than the initial absorption of a single tablet.
Understanding BI 8 Prescription Dosage
Prescription-dose information needs to be interpreted carefully.
Current labeling says the total prescription amount should not exceed 3,200 mg per day, but that represents a maximum labeled daily ceiling in clinician-directed treatment not a recommended self-treatment target.
For mild-to-moderate pain, current labeling lists 400 mg every four to six hours when needed and reports that, in controlled analgesic studies, doses higher than 400 mg were not more effective than 400 mg.
| Question | What Prescription Labeling Indicates |
|---|---|
| Does BI 8 contain 800 mg? | Yes |
| Should everyone take 800 mg at once? | No |
| Is more than 400 mg always more effective for pain? | No |
| Labeled maximum prescription total | 3,200 mg/day |
| Is 3,200 mg/day a self-treatment recommendation? | No |
| General NSAID principle | Lowest effective dose for shortest necessary duration |
Do not use this table to determine your personal dose.
Prescription dosing depends on the medical condition, response to treatment, health history, and clinician’s instructions.
Why More Ibuprofen Is Not Always Better
A common misconception is that twice as much ibuprofen must provide twice as much pain relief.
That is not necessarily true.
Current prescription labeling specifically reports that doses above 400 mg did not show greater effectiveness than 400 mg in controlled trials for mild-to-moderate pain.
At the same time, higher total NSAID exposure can increase adverse-effect concerns.
The appropriate goal is therefore not to take the strongest available tablet.
It is to use the lowest effective dose appropriate for the condition for the shortest necessary duration, under appropriate medical guidance.
How Should Prescription Ibuprofen Be Taken?
Follow the instructions provided with your prescription.
General safety principles include:
- Take only the prescribed amount
- Do not take extra doses because pain remains severe
- Do not increase frequency without medical advice
- Avoid taking another NSAID at the same time unless directed
- Check OTC cold, flu, sleep, and pain products for hidden NSAIDs
- Tell the prescriber about all other medications and supplements
- Do not share prescription ibuprofen
If ibuprofen causes gastrointestinal discomfort, current labeling notes that it may be administered with meals or milk.
Taking it with food, however, does not eliminate the risk of ulcers or gastrointestinal bleeding.
Common BI 8 White Pill Side Effects
Common NSAID side effects can include:
- Nausea
- Heartburn
- Stomach discomfort
- Diarrhea
- Constipation
- Gas
- Vomiting
- Dizziness
- Headache
- Bloating
FDA information lists stomach pain, constipation, diarrhea, gas, heartburn, nausea, vomiting, and dizziness among common NSAID effects.
Mild symptoms may not represent an emergency, but persistent, severe, or worsening symptoms should be discussed with a healthcare professional.
Serious BI 8 White Pill Side Effects and Warnings
Prescription-strength ibuprofen can cause serious side effects, especially with higher doses, long-term use, or certain medical conditions.
Gastrointestinal Bleeding, Ulcers, and Perforation
NSAIDs can cause:
- Stomach or intestinal ulcers
- Gastrointestinal bleeding
- Digestive-tract perforation
These problems can occur without warning and may be serious or fatal.
Risk is higher in people with:
- Previous ulcers or GI bleeding
- Older age
- Anticoagulant or corticosteroid use
- Heavy alcohol use
- Smoking
- Long-term NSAID use
Warning Signs of GI Bleeding
Seek urgent medical care for:
- Black or tarry stools
- Vomiting blood
- Vomit resembling coffee grounds
- Blood in stool
- Severe abdominal pain
- Fainting or unusual weakness
Heart Attack and Stroke Risk
NSAIDs may increase the risk of heart attack and stroke, including in people without known heart disease.
Seek emergency care for:
- Chest pain
- Sudden weakness or numbness
- Trouble speaking
- Severe shortness of breath
- Sudden neurological symptoms
Ibuprofen should not be used around coronary artery bypass graft surgery (CABG).
High Blood Pressure
Ibuprofen may cause new high blood pressure or worsen existing hypertension.
Extra caution is needed with:
- ACE inhibitors
- ARBs
- Thiazide diuretics
- Loop diuretics
NSAIDs may also reduce the effectiveness of some blood-pressure medicines.
Heart Failure and Fluid Retention
NSAIDs can cause fluid retention and may worsen heart failure.
Watch for:
- Swollen feet or ankles
- Rapid unexplained weight gain
- Shortness of breath
BI 8 White Pill and Kidney Problems
NSAIDs can reduce kidney blood flow and may cause kidney injury.
Risk is higher with:
- Kidney disease
- Heart failure
- Liver disease
- Dehydration
- Older age
- Diuretic or ACE inhibitor use
Possible warning signs include:
- Reduced urination
- Swelling

BI 8 White Pill and Liver Problems
Rare but serious liver reactions can occur with ibuprofen, including hepatitis, jaundice, and liver failure.
Seek medical advice for:
- Yellow skin or eyes
- Persistent nausea
- Unusual fatigue
- Itching
- Upper-right abdominal pain
Serious Skin Reactions
Rare life-threatening skin reactions can occur, including Stevens-Johnson syndrome and toxic epidermal necrolysis.
Stop taking the medicine and seek prompt medical care for:
- Severe rash
- Blistering
- Peeling skin
- Fever with rash
DRESS Reaction
Ibuprofen can rarely cause Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS).
Possible symptoms include:
- Fever
- Rash
- Facial swelling
- Swollen lymph nodes
DRESS may also affect organs such as the liver, kidneys, and heart.
Severe Allergic Reactions
Seek emergency help for:
- Difficulty breathing
- Face, lip, tongue, or throat swelling
- Severe wheezing
- Fainting or collapse
People with previous serious reactions to aspirin or other NSAIDs should tell their healthcare professional.
The Two Major Boxed-Warning Risks
| Major Risk | Why It Matters |
|---|---|
| Cardiovascular thrombotic events | Increased risk of heart attack and stroke |
| Gastrointestinal bleeding, ulceration and perforation | Can occur without warning and may be fatal |
These are the two major boxed-warning risks associated with prescription NSAIDs such as the BI 8 White Pill.
Does Long-Term Ibuprofen Use Require Monitoring?
Yes, clinicians may monitor patients who use NSAIDs for extended periods.
Current prescription labeling recommends periodic CBC and chemistry profiles for people receiving long-term NSAID treatment because serious gastrointestinal bleeding, renal abnormalities, liver abnormalities, and hematologic changes can occur.
Depending on the patient, monitoring may include:
- Blood pressure
- Kidney function
- Liver laboratory tests
- Complete blood count
- Hemoglobin
- Hematocrit
- Signs of gastrointestinal blood loss
- Fluid retention
Ibuprofen labeling also notes that anemia can occur during NSAID treatment, sometimes because of gastrointestinal blood loss or other mechanisms.
The exact tests and frequency depend on the individual patient’s health and duration of therapy.
Who Should Not Take the BI 8 White Pill?
Current labeling identifies important contraindications.
Ibuprofen should not be taken by someone with:
- Known hypersensitivity to ibuprofen
- A history of certain severe allergic reactions to aspirin or another NSAID
- NSAID-related asthma or hives in relevant circumstances
Ibuprofen is also contraindicated around CABG surgery.
Additional conditions that require careful medical review include:
- Previous stomach ulcer
- Previous GI bleeding
- Kidney disease
- Liver disease
- Heart disease
- Recent heart attack
- Heart failure
- High blood pressure
- Asthma
- Bleeding disorders
- Significant dehydration
BI 8 White Pill Drug Interactions
Ibuprofen can interact with several medications.
| Medication/Class | Main Concern |
|---|---|
| Aspirin | Increased side effects and possible interference with antiplatelet action |
| Other NSAIDs | Higher GI, kidney, and cardiovascular risk |
| Warfarin/anticoagulants | Increased bleeding risk |
| ACE inhibitors | Reduced blood-pressure effect and kidney concerns |
| ARBs | Blood-pressure and kidney concerns |
| Diuretics | Reduced effectiveness and kidney risk |
| Lithium | Increased lithium levels |
| Methotrexate | Potential increased toxicity |
| Corticosteroids | Increased GI bleeding risk |
| SSRIs/SNRIs | Increased bleeding risk |
Current labeling describes important interactions with aspirin, ACE inhibitors, diuretics, lithium, methotrexate, and anticoagulants.
Because this list is not complete, tell your doctor or pharmacist about all medications and supplements you take.
Can You Take BI 8 With Aspirin?
Do not automatically combine prescription ibuprofen with aspirin.
Both medications affect pathways related to inflammation and platelet function, and combining them may increase adverse effects.
Ibuprofen can also interfere with the antiplatelet activity of low-dose aspirin under certain timing conditions.
People taking aspirin for heart attack or stroke prevention should discuss ibuprofen use with their clinician or pharmacist rather than attempting to create their own dosing schedule.
Can You Take BI 8 With Naproxen?
Ibuprofen and naproxen are both NSAIDs.
Using them together can increase the risk of:
- Stomach irritation
- Ulcers
- GI bleeding
- Kidney injury
- Cardiovascular complications
Unless specifically instructed by a healthcare professional, avoid stacking multiple NSAIDs.
Can You Take Acetaminophen With BI 8?

Acetaminophen is not an NSAID and has a different mechanism from ibuprofen.
Healthcare professionals sometimes use acetaminophen and ibuprofen in the same overall treatment plan.
However, a person taking prescription-strength ibuprofen 800 mg should not create a combined medication schedule without considering:
- Total medication exposure
- Liver health
- Kidney health
- Alcohol use
- Other medications
- Reason for treatment
Ask a pharmacist or prescriber for an individualized plan.
Can You Drink Alcohol While Taking BI 8?
Alcohol can increase gastrointestinal concerns associated with NSAIDs.
MedlinePlus identifies significant alcohol consumption as one factor associated with increased gastrointestinal bleeding risk during ibuprofen use.
Ask the prescribing clinician whether alcohol is appropriate based on your specific risk factors.
BI 8 White Pill and Pregnancy
Pregnancy requires special caution with NSAIDs.
The FDA recommends avoiding NSAIDs at approximately 20 weeks of pregnancy or later unless specifically advised by a healthcare professional because they can cause fetal kidney problems that may reduce amniotic fluid.
- Limiting NSAID use between approximately 20 and 30 weeks when medically necessary
- Using the lowest effective dose for the shortest duration
- Considering ultrasound monitoring of amniotic fluid if treatment continues beyond 48 hours
- Avoiding NSAIDs at approximately 30 weeks and later because of the additional risk of premature closure of the fetal ductus arteriosus
Anyone who is pregnant or may be pregnant should discuss prescription ibuprofen with a healthcare professional.
BI 8 White Pill and Breastfeeding
Ibuprofen is generally considered one of the better-studied NSAIDs during breastfeeding because transfer into breast milk is low.
However, an 800 mg prescription tablet should still be taken only according to a healthcare professional’s instructions.
Breastfeeding status should be disclosed when medications are prescribed.
Can Older Adults Take Ibuprofen 800 mg?
Older adults can be more vulnerable to NSAID complications.
Important risks include:
- Gastrointestinal bleeding
- Kidney dysfunction
- Medication interactions
- Fluid retention
- Blood-pressure changes
- Cardiovascular events
MedlinePlus advises older adults, particularly those 75 and older, to discuss the risks and benefits of ibuprofen therapy with their clinician.
Age alone does not determine whether ibuprofen is appropriate, but it can change the risk-benefit calculation.
Can Children Take the BI 8 White Pill?
Do not give a child an 800 mg prescription tablet simply because pediatric ibuprofen products exist.
Children’s ibuprofen is commonly dosed using age, weight, product concentration, and medical indication.
Current prescription-tablet labeling states that controlled clinical trials establishing the safety and effectiveness of these ibuprofen tablets in children have not been conducted.
A child should receive prescription-strength ibuprofen only when specifically directed by an appropriate healthcare professional.
BI 8 White Pill Before Surgery or Dental Procedures
Tell the healthcare professional performing a procedure that you are taking ibuprofen.
MedlinePlus specifically advises patients to inform their doctor or dentist before surgery, including dental surgery.
This matters because NSAIDs can influence:
- Platelet function
- Bleeding
- Kidney function
- Other medications used during procedures
Do not independently decide how many days before surgery to stop prescription ibuprofen.
The correct stop time depends on:
- Type of procedure
- Bleeding risk
- Reason ibuprofen is being used
- Other medications
- Individual medical history
Follow the instructions of the surgeon, dentist, anesthesiologist, pharmacist, or prescribing clinician.
Can You Cut or Split a BI 8 Pill?
Current DailyMed product information describes the BI 8 ibuprofen 800 mg tablet as unscored.
Because it is not scored, do not assume that splitting the pill will reliably provide two exact 400 mg doses.
If your prescribed amount has changed, ask a pharmacist or healthcare professional whether:
- Your specific tablet can be split
- A 400 mg tablet would be preferable
- A different strength should be prescribed
Do not alter a prescription tablet solely to create your own dose.
Is the BI 8 White Pill Addictive?
Ibuprofen is not an opioid and is not considered addictive in the same way as narcotic pain medicines.
Nevertheless, inappropriate use can produce serious medical harm.
Excessive or prolonged use can increase the risk of:
- Kidney injury
- GI bleeding
- Ulceration
- Cardiovascular complications
- Medication interactions
- Liver abnormalities
“Not addictive” does not mean “safe in unlimited amounts.”
What Happens If You Take Too Much Ibuprofen?
Ibuprofen overdose can be dangerous.
Symptoms may include:
- Nausea
- Vomiting
- Abdominal pain
- Drowsiness
- Lethargy
- Dizziness
Severe poisoning may cause more serious neurological, cardiovascular, renal, or metabolic complications.
If an overdose is suspected, seek urgent medical or poison-control assistance rather than waiting for symptoms to appear.
Do not induce vomiting or attempt an internet-based overdose treatment unless directed by qualified medical professionals.
What If You Miss a Dose?
Instructions depend on whether prescription ibuprofen is being taken:
- Regularly
- On an as-needed basis
Do not automatically take a double dose to compensate for a forgotten tablet.
Check the prescription instructions or ask the dispensing pharmacist if you are uncertain.
What If You Find a BI 8 White Pill Without a Bottle?
Finding a tablet that appears to say BI 8 does not guarantee that it is safe to take.
Use this process:
- Do not swallow the tablet
- Check the imprint on both sides
- Note its shape and color
- Compare it with your original prescription if applicable
- Keep it away from children and pets
- Ask a pharmacist to verify the medication
Online pill-identification information can narrow down possibilities, but it cannot confirm the source or authenticity of an unknown tablet.
How to Store the BI 8 White Pill
Current labeling recommends controlled room-temperature storage at approximately:
20°C to 25°C (68°F to 77°F)
and protection from excessive heat.
For safer medication storage:
- Use the original labeled container
- Keep the container tightly closed
- Protect it from excessive heat and moisture
- Keep it away from children
- Avoid storing mixed tablets in unlabeled containers
- Do not share the prescription
BI 8 White Pill vs Other Pain Relievers
| Medication | Type | Common Role | Major Concern |
|---|---|---|---|
| Ibuprofen | NSAID | Pain/inflammation | GI, kidney and cardiovascular risks |
| Naproxen | NSAID | Pain/inflammation | Similar NSAID risks |
| Aspirin | NSAID/antiplatelet | Pain or cardiovascular use depending on dose | Bleeding |
| Acetaminophen | Analgesic/antipyretic | Pain and fever | Liver toxicity when excessive |
| Opioids | Opioid analgesics | Selected moderate-to-severe pain | Sedation, respiratory depression, dependence |
There is no single “best” pain medicine for every person.
The appropriate option depends on the condition, health history, other medications, and treatment goals.
Emergency vs Non-Emergency Symptoms
| Symptom | Appropriate Action |
|---|---|
| Mild temporary stomach upset | Discuss with a healthcare professional if persistent or troublesome |
| Persistent nausea or abdominal discomfort | Contact a healthcare professional |
| Black/tarry stool | Seek urgent medical care |
| Vomiting blood | Seek urgent medical care |
| Chest pain | Emergency medical care |
| Sudden weakness or speech difficulty | Emergency medical care |
| Facial or throat swelling | Emergency medical care |
| Difficulty breathing | Emergency medical care |
| New severe rash or blistering | Stop the medication and seek prompt medical evaluation |
| Yellow skin or eyes | Prompt medical evaluation |
| Markedly reduced urination | Prompt medical evaluation |
| Severe unexplained swelling | Prompt medical evaluation |
| Suspected overdose | Seek urgent medical/poison-control assistance |
Serious GI, cardiovascular, kidney, hepatic, allergic, and skin complications are documented in current ibuprofen labeling.
Common Mistakes With the BI 8 White Pill
- Assuming BI 4, BI 6, and BI 8 are the same strength
- Thinking 800 mg always works better for pain
- Taking ibuprofen with another NSAID such as naproxen
- Forgetting that some cold, flu, or headache medicines contain NSAIDs
- Believing food completely prevents stomach bleeding
- Taking someone else’s prescription ibuprofen
- Doubling the dose after missing one
- Splitting an unscored BI 8 tablet without asking a pharmacist
- Taking more than prescribed because pain continues
- Ignoring possible drug interactions or medical conditions
