Concurrent use of other NSAIDs, salicylate drugs like aspirin, or pemetrexed.
Fertility issues or ongoing fertility evaluation, as this medication may affect fertility.
* Pregnancy, planned pregnancy, or suspected pregnancy. This medication can harm an unborn baby if taken after 20 weeks of gestation. If you are between 20 and 30 weeks pregnant, only take this medication under your doctor's guidance. Do not take this medication if you are more than 30 weeks pregnant.
This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. Verify that it is safe to take this medication with your existing treatments and health status. Never start, stop, or adjust the dosage of any medication without consulting your doctor.
Precautions & Cautions
There is a risk of developing high blood pressure with this type of medication. Your doctor will advise you on how often to have your blood pressure checked. Additionally, consult your doctor before consuming alcohol, as it may interact with this medication.
If you smoke, discuss this with your doctor, as it may affect your treatment. Individuals with asthma should also consult their doctor, as they may be more sensitive to this medication.
To minimize the risk of severe side effects, do not exceed the prescribed dosage, and do not take this medication for longer than recommended by your doctor. Be cautious and avoid injuries, as this medication may increase your risk of bleeding. Use a soft toothbrush and an electric razor to reduce the risk of bleeding.
The use of this medication may increase the risk of heart failure, particularly in individuals who already have heart failure. This may lead to a higher risk of heart attack, hospitalization for heart failure, and death. Discuss this with your doctor to understand the potential risks.
In people who have recently experienced a heart attack, the use of this medication may increase the risk of another heart attack and heart-related death. Additionally, individuals taking this medication after a first heart attack may have a higher risk of death within the following year compared to those not taking this medication. Consult your doctor to discuss these potential risks.
This medication may also increase the risk of a severe brain problem called aseptic meningitis. Seek medical attention immediately if you experience symptoms such as headache, fever, chills, severe nausea or vomiting, stiff neck, rash, sensitivity to light, drowsiness, or confusion.
In rare cases, this medication may cause liver problems, which can be life-threatening. Monitor for signs of liver problems, including dark urine, fatigue, decreased appetite, nausea or stomach pain, pale stools, vomiting, or yellowing of the skin or eyes. If you experience any of these symptoms, contact your doctor promptly.
If you are 60 years or older, use this medication with caution, as you may be more susceptible to side effects. Women of childbearing age should be aware that this medication may affect ovulation, which can impact fertility. However, this effect is reversible, and ovulation typically returns to normal after stopping the medication. Discuss this with your doctor if you are planning to become pregnant.
If you are breastfeeding, consult your doctor to discuss the potential risks to your baby.

Monitoring
Baseline Monitoring
Rationale: To establish baseline kidney function, especially important for patients with pre-existing renal impairment or those at risk (elderly, dehydrated, concomitant nephrotoxic drugs).
Timing: Before initiating long-term therapy or in at-risk patients.
Rationale: To establish baseline liver function, especially for patients with pre-existing hepatic impairment or those on long-term therapy.
Timing: Before initiating long-term therapy or in at-risk patients.
Rationale: NSAIDs can cause new onset hypertension or worsen pre-existing hypertension.
Timing: Before initiating therapy.
Routine Monitoring
Frequency: Periodically (e.g., every 6-12 months for chronic use, more frequently in high-risk patients or with dose changes)
Target: Within normal limits or stable from baseline
Action Threshold: Significant increase in creatinine (>20% from baseline), signs of acute kidney injury.
Frequency: Periodically (e.g., every 6-12 months for chronic use, if symptoms of liver injury develop)
Target: Within normal limits or stable from baseline
Action Threshold: Significant elevation (e.g., >3x ULN), signs of liver injury.
Frequency: Regularly (e.g., at each visit for chronic use)
Target: Individualized, within target range for patient
Action Threshold: Sustained elevation, new onset hypertension.
Frequency: Periodically (e.g., annually for chronic use, if signs of anemia or bleeding)
Target: Within normal limits
Action Threshold: Significant drop in hemoglobin/hematocrit, signs of GI bleeding.
Frequency: Annually for chronic use, or if GI symptoms present
Target: Negative
Action Threshold: Positive test, signs of GI bleeding.
Symptom Monitoring
- Signs of gastrointestinal bleeding (black, tarry stools; coffee-ground vomit; severe abdominal pain)
- Signs of renal dysfunction (decreased urine output, swelling in ankles/feet, unusual fatigue)
- Signs of cardiovascular events (chest pain, shortness of breath, weakness on one side of body, slurred speech)
- Signs of liver injury (yellowing of skin/eyes, dark urine, persistent nausea/vomiting, unusual fatigue)
- Signs of allergic reaction (rash, itching, hives, swelling of face/lips/tongue/throat, difficulty breathing)
- Unusual bruising or bleeding
Special Patient Groups
Pregnancy
Avoid use in the third trimester due to risk of premature closure of the fetal ductus arteriosus and persistent pulmonary hypertension of the newborn. Use in the first and second trimesters should be avoided unless the potential benefit outweighs the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Considered compatible with breastfeeding when used at usual analgesic doses for short periods. Low levels are excreted into breast milk.
Pediatric Use
Ibuprofen 400mg tablets are generally not recommended for children under 12 years of age due to dosing considerations (weight-based dosing is preferred for younger children) and potential for overdose. Pediatric formulations (suspensions, chewable tablets) are available for appropriate dosing in younger children.
Geriatric Use
Elderly patients are at increased risk for serious adverse reactions to NSAIDs, including gastrointestinal bleeding, ulceration, perforation, renal impairment, and cardiovascular events. Use the lowest effective dose for the shortest duration possible. Monitor renal function and for signs of GI bleeding closely.
Clinical Information
Clinical Pearls
- Always advise patients to take ibuprofen with food, milk, or a full glass of water to minimize GI upset.
- Educate patients on the signs of GI bleeding (black, tarry stools; coffee-ground vomit) and to seek immediate medical attention if they occur.
- Remind patients that ibuprofen can interact with many common medications, including blood thinners, blood pressure medications, and other pain relievers. Advise them to inform their healthcare provider of all medications they are taking.
- For chronic use, emphasize the importance of regular monitoring of blood pressure, renal function, and liver function.
- Counsel patients on the maximum daily dose for OTC use (1200 mg/day) and prescription use (3200 mg/day) to prevent overdose.
- NSAIDs like ibuprofen should be avoided in patients with severe heart failure or advanced kidney disease.
Alternative Therapies
- Acetaminophen (Tylenol) - for pain and fever, no anti-inflammatory effect, different side effect profile.
- Naproxen (Aleve) - another NSAID with longer half-life, allowing less frequent dosing.
- Aspirin - another NSAID, but with distinct antiplatelet effects at low doses.
- Celecoxib (Celebrex) - COX-2 selective NSAID, potentially lower GI risk but similar cardiovascular risk.
- Opioid analgesics (for severe pain, with higher risk of dependence and side effects).
- Topical analgesics (e.g., diclofenac gel, capsaicin cream) - for localized pain.
