Diclofenac is a widely used nonsteroidal anti-inflammatory drug (NSAID) that helps manage pain and inflammation in various conditions such as arthritis, sprains, and other musculoskeletal disorders. As frontline caregivers, nurses play a vital role in ensuring its safe and effective use. This article explores the essential nursing considerations and management strategies for diclofenac, empowering nurses to optimize patient care while minimizing risks.

What is Diclofenac?
Diclofenac, commonly known by brand names such as Voltaren, Cataflam, and Zorvolex, is an NSAID that reduces the production of prostaglandins—chemicals responsible for inflammation, pain, and fever. It is available in multiple forms, including oral tablets, topical gels, patches, and injectable solutions, making it adaptable to diverse patient needs.
Common Uses of Diclofenac
- Osteoarthritis
- Rheumatoid arthritis
- Ankylosing spondylitis
- Acute musculoskeletal pain (e.g., sprains, strains)
- Migraine headaches (in some formulations)
- Postoperative pain
Nursing Considerations for Diclofenac
Nurses must exercise diligence when administering diclofenac due to its potential side effects and drug interactions. The following sections outline key nursing responsibilities: assessment, administration, monitoring, and special considerations.
Assessment
Prior to administration, nurses should:
- Evaluate pain levels using a standardized scale (e.g., 0-10 numeric rating scale).
- Review medical history for contraindications, including:
- Allergies to NSAIDs or aspirin
- History of gastrointestinal (GI) bleeding or ulcers
- Kidney or liver disease
- Cardiovascular conditions (e.g., heart failure, hypertension)
- Asthma (due to risk of bronchospasm)
- Check current medications for potential interactions with:
- Anticoagulants (e.g., warfarin)
- Other NSAIDs or aspirin
- ACE inhibitors or diuretics
- Lithium or methotrexate
Administration
Diclofenac’s various forms require specific administration techniques:
- Oral tablets/capsules: Take with food or milk to minimize GI upset. Swallow whole; do not crush or chew.
- Topical gel or patch: Apply to clean, intact skin, avoiding eyes or mucous membranes.
- Injectable: Administer intramuscularly or intravenously as prescribed, using aseptic technique.
Verify the dosage and route to ensure accuracy and prevent errors.
Monitoring
Post-administration, nurses should:
- Assess pain relief to confirm the medication’s effectiveness.
- Monitor for side effects, such as:
- GI issues (e.g., nausea, dyspepsia, abdominal pain)
- Signs of GI bleeding (e.g., black stools, hematemesis)
- Renal impairment (e.g., decreased urine output, edema)
- Allergic reactions (e.g., rash, itching, bronchospasm)
- Cardiovascular events (e.g., chest pain, shortness of breath)
- Track vital signs, particularly blood pressure, as diclofenac may elevate it.
Special Considerations
Certain populations require heightened caution:
- Elderly patients: Increased risk of GI bleeding, renal issues, and cardiovascular events; use the lowest effective dose.
- Patients with heart disease: Higher risk of heart attack or stroke, especially with prolonged use.
- Pregnant women: Avoid in the third trimester due to potential fetal harm (e.g., premature closure of the ductus arteriosus).
- Patients with asthma: Watch for bronchospasm, as NSAIDs can exacerbate symptoms.
Patient Education for Diclofenac
Effective patient education enhances safety and compliance. Nurses should teach patients:
- Follow the prescription: Do not exceed the recommended dose or duration.
- Report side effects: Contact a healthcare provider for signs of GI bleeding (e.g., black stools, severe abdominal pain), allergic reactions, or other unusual symptoms.
- Avoid alcohol: It heightens the risk of GI bleeding when combined with NSAIDs.
- Drug interactions: Inform providers about all medications, including over-the-counter drugs and supplements.
- Topical use: Apply gels or patches only to intact skin, wash hands after use, and avoid bandaging unless instructed.
- Missed doses: Take as soon as remembered unless nearing the next dose; do not double up.
Conclusion
Diclofenac is a valuable tool for pain and inflammation management, but its use demands careful nursing oversight. Through comprehensive assessments, proper administration, diligent monitoring, and thorough patient education, nurses can mitigate risks and enhance outcomes. Staying attuned to diclofenac’s effects, particularly in high-risk groups, ensures safe and effective care delivery.
