Precautions & Cautions
If you are taking this drug for an extended period, your doctor may recommend regular blood tests to monitor your condition. Be sure to discuss this with your doctor.
There is a risk of developing high blood pressure with medications like this one. Follow your doctor's instructions for checking your blood pressure regularly.
Before consuming alcohol, consult with your doctor to discuss any potential risks or interactions.
If you smoke, talk to your doctor about the potential effects on your health while taking this medication.
If you have asthma, consult with your doctor, as you may be more sensitive to this drug.
Adhere to the prescribed dosage and do not exceed the recommended amount, as taking more than directed may increase the risk of severe side effects. Additionally, do not take this medication for longer than your doctor has prescribed.
Be cautious, as this medication may increase your risk of bleeding easily. To minimize this risk, use a soft toothbrush and an electric razor, and avoid injuries.
The use of medications like this one may increase the risk of heart failure. If you already have heart failure, your risk of heart attack, hospitalization for heart failure, and death may be higher. Discuss this with your doctor.
In people who have recently experienced a heart attack, the risk of another heart attack and heart-related death may be increased when taking medications like this one. Furthermore, individuals taking this type of medication after a first heart attack may have a higher likelihood of death within the following year compared to those not taking this medication. Consult with your doctor to discuss these risks.
If you are taking aspirin to prevent a heart attack, inform your doctor, as this may affect your treatment plan.
If you have phenylketonuria (PKU), consult with your doctor, as some products contain phenylalanine.
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects.
Medications like this one, which are classified as NSAIDs, may affect ovulation, potentially impacting fertility. However, this effect is reversible when the medication is stopped. Discuss this with your doctor if you have concerns.
If you are breastfeeding, inform your doctor, as you will need to discuss any potential risks to your baby.

Monitoring
Baseline Monitoring
Rationale: To establish baseline and monitor for anemia or other hematologic abnormalities, especially with long-term use.
Timing: Prior to initiation
Rationale: To assess baseline kidney function, as NSAIDs can cause renal impairment.
Timing: Prior to initiation
Rationale: To assess baseline liver function, as NSAIDs can cause liver injury.
Timing: Prior to initiation
Rationale: To establish baseline, as NSAIDs can cause new onset hypertension or worsen pre-existing hypertension.
Timing: Prior to initiation
Routine Monitoring
Frequency: Periodically, especially in patients at risk for renal impairment (e.g., elderly, heart failure, diuretic use)
Target: Within normal limits or stable from baseline
Action Threshold: Significant increase in creatinine or decrease in eGFR; consider dose adjustment or discontinuation.
Frequency: Periodically, especially with long-term use or if symptoms of liver dysfunction develop
Target: Within normal limits or stable from baseline
Action Threshold: Significant elevation (e.g., >3x ULN); consider discontinuation.
Frequency: Regularly, especially in hypertensive patients
Target: Individualized target BP
Action Threshold: Sustained increase in BP; consider antihypertensive adjustment or NSAID discontinuation.
Frequency: Periodically with long-term use
Target: Within normal limits
Action Threshold: Significant decrease in hemoglobin/hematocrit or other abnormalities; investigate for GI bleeding or other causes.
Symptom Monitoring
- Signs of gastrointestinal bleeding (e.g., black, tarry stools; coffee-ground vomit; severe abdominal pain)
- Symptoms of cardiovascular events (e.g., chest pain, shortness of breath, weakness on one side of the body, slurred speech)
- Signs of renal impairment (e.g., decreased urine output, swelling in ankles/feet, unusual fatigue)
- Symptoms of liver injury (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, flu-like symptoms)
- Signs of allergic reaction (e.g., rash, hives, itching, difficulty breathing, swelling of face/lips/tongue/throat)
- Symptoms of fluid retention/edema
- Changes in vision or hearing (rare, but reported with NSAIDs)
Special Patient Groups
Pregnancy
Avoid use in the third trimester of pregnancy due to the risk of premature closure of the fetal ductus arteriosus. Use in the first and second trimesters should only be if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Diclofenac is excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established for the treatment of acute migraine. Not recommended for use in children.
Geriatric Use
Elderly patients are at greater risk for serious cardiovascular, gastrointestinal, and renal adverse events. Use the lowest effective dose for the shortest duration possible. Monitor closely for adverse effects, especially GI bleeding and renal impairment.
Clinical Information
Clinical Pearls
- Cambia is specifically formulated for rapid absorption to treat acute migraine, with a Tmax of 0.5 hours.
- It must be taken on an empty stomach (1 hour before or 2 hours after food) for optimal efficacy.
- Unlike some other NSAIDs, Cambia is not indicated for chronic pain or prophylactic migraine treatment.
- Patients should be advised about the black box warnings for cardiovascular and gastrointestinal risks, even with short-term use for acute conditions.
- Ensure patients understand that this is a single-dose treatment for an acute attack and not for daily use.
Alternative Therapies
- Other NSAIDs (e.g., ibuprofen, naproxen, celecoxib)
- Triptans (e.g., sumatriptan, zolmitriptan, rizatriptan)
- CGRP receptor antagonists (e.g., ubrogepant, rimegepant)
- Ergot alkaloids (e.g., ergotamine, dihydroergotamine)
- Acetaminophen
- Opioid analgesics (generally not recommended for migraine due to abuse potential and risk of medication overuse headache)
