Voltaren (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID) available in multiple formulations, including oral tablets, topical gels, and solutions. It is widely prescribed and recognized for its efficacy in managing pain and inflammation associated with various musculoskeletal conditions. As a potent inhibitor of cyclooxygenase (COX) enzymes, it reduces prostaglandin synthesis, addressing both symptomatic discomfort and underlying inflammatory pathways. This product card provides a comprehensive, evidence-based overview for healthcare professionals and informed patients, detailing its appropriate use, mechanism, and safety profile.
Features
- Active ingredient: Diclofenac sodium or diclofenac epolamine (depending on formulation)
- Available forms: Oral tablets (including delayed-release and extended-release), topical gel (1% or 3%), topical solution, suppositories, and ophthalmic solutions
- Mechanism: Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor
- Prescription status: Available by prescription and over-the-counter (OTC) in some regions and strengths
- Onset of action: Topical formulations provide localized relief within hours; oral forms may take several days for full anti-inflammatory effect
Benefits
- Effectively reduces pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis
- Topical formulations minimize systemic absorption, reducing risk of gastrointestinal and cardiovascular side effects compared to oral NSAIDs
- Provides targeted relief for acute musculoskeletal pain, such as sprains, strains, and sports injuries
- Multiple administration routes allow for personalized treatment plans based on patient needs and contraindications
- Well-established efficacy and safety profile supported by decades of clinical use and research
Common use
Voltaren is commonly used for the management of mild to moderate pain and inflammation. Oral forms are indicated for osteoarthritis, rheumatoid arthritis, and acute pain conditions such as primary dysmenorrhea. Topical gel is approved for the relief of pain associated with osteoarthritis in joints amenable to topical treatment, such as the knees and hands. It is also used off-label for other inflammatory conditions, acute musculoskeletal injuries, and tendinitis, under professional guidance.
Dosage and direction
Dosage varies by formulation and indication. For oral tablets in adults: osteoarthritis—50 mg two to three times daily or 75 mg twice daily; rheumatoid arthritis—50 mg three to four times daily or 75 mg twice daily. Maximum daily dose should not exceed 150 mg. For topical gel (1%): apply 4 g to affected area four times daily; for osteoarthritis of the knees, apply 4 g four times daily to each knee. Hands: apply 2 g four times daily to each hand. Use the lowest effective dose for the shortest duration possible. Administer with food or milk to reduce gastrointestinal upset. Do not apply topical gel to damaged skin, open wounds, or under occlusive dressings.
Precautions
Use with caution in patients with a history of gastrointestinal ulceration or bleeding, cardiovascular disease, hypertension, renal impairment, hepatic dysfunction, or asthma. Avoid use in dehydration; ensure adequate fluid intake. Monitor renal function and blood pressure periodically during long-term therapy. Topical use: avoid contact with eyes, mucous membranes, and non-intact skin. Do not combine with other topical products unless directed. Sun exposure should be minimized on treated areas due to potential photosensitivity. Use in elderly patients may require dose adjustment due to increased risk of adverse effects.
Contraindications
Hypersensitivity to diclofenac, aspirin, or other NSAIDs. History of asthma, urticaria, or allergic-type reactions after taking NSAIDs. Peri-operative pain in setting of coronary artery bypass graft (CABG) surgery. Severe heart failure. Active peptic ulcer disease or gastrointestinal bleeding. Severe renal impairment or advanced kidney disease. Third trimester of pregnancy.
Possible side effect
Common side effects include gastrointestinal symptoms (dyspepsia, nausea, abdominal pain, diarrhea), headache, dizziness, and localized reactions with topical use (rash, dryness, itching). Serious side effects may include gastrointestinal bleeding or perforation, cardiovascular thrombotic events (myocardial infarction, stroke), hypertension, heart failure, renal injury, hepatotoxicity, severe skin reactions, and hematologic abnormalities. Discontinue use and seek medical attention if signs of allergic reaction (swelling, difficulty breathing) or serious adverse events occur.
Drug interaction
May interact with other NSAIDs or aspirin, increasing risk of gastrointestinal toxicity. Concurrent use with anticoagulants (e.g., warfarin) may increase bleeding risk. ACE inhibitors, angiotensin receptor blockers, and diuretics may have reduced antihypertensive effects and increased risk of renal impairment. Cyclosporine and tacrolimus may increase nephrotoxicity. Lithium levels may increase. Methotrexate toxicity may be enhanced. Topical diclofenac has minimal systemic interactions but should not be used with other topical NSAIDs or products without consulting a healthcare provider.
Missed dose
If a dose is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to make up for a missed one. For topical formulations, apply the next dose at the regular time; do not apply extra gel. Maintain regular dosing schedule to ensure consistent therapeutic levels.
Overdose
Symptoms of overdose may include nausea, vomiting, epigastric pain, gastrointestinal bleeding, drowsiness, dizziness, tinnitus, apnea, coma, seizures, hypertension, acute renal failure, and hepatotoxicity. Management is supportive and symptomatic; there is no specific antidote. Gastric lavage or activated charcoal may be considered if presented early. Hemodialysis is not effective due to high protein binding. Seek immediate medical attention or contact a poison control center.
Storage
Store at room temperature (20–25°C or 68–77°F), away from light, moisture, and heat. Keep out of reach of children and pets. Do not freeze. For topical gel, ensure the tube is tightly closed when not in use. Do not store in bathroom cabinets where humidity levels vary. Discard any unused medication after the expiration date.

Reviews
Voltaren has been extensively studied and is generally well-regarded in clinical practice for its efficacy in pain and inflammation management. Many patients report significant improvement in mobility and pain scores, particularly with topical formulations which offer favorable local effect with minimal systemic exposure. Some criticisms include gastrointestinal side effects with oral forms and skin reactions with topical use. Overall, it remains a first-line option in many guidelines for musculoskeletal conditions.
