Voltaren (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID) available in multiple formulations, including oral tablets, topical gels, and ophthalmic solutions. It is widely prescribed and recognized for its potent anti-inflammatory, analgesic, and antipyretic properties. This product card provides a comprehensive, expert-level overview of its appropriate use, mechanisms, and safety profile for healthcare professionals and informed patients. Proper application and adherence to dosing guidelines are critical for maximizing therapeutic benefits while minimizing risks.
Features
- Active ingredient: Diclofenac sodium or diclofenac epolamine
- Available formulations: Oral tablets (including delayed-release and extended-release), topical gel (1% or 3%), solution for ophthalmic use, suppositories, and injectable forms
- Mechanism: Potent cyclooxygenase (COX) inhibitor, reducing prostaglandin synthesis
- Onset of action: Varies by formulation; topical gel may provide localized relief within hours, oral forms typically within 30–60 minutes
- Duration: Dependent on formulation; oral tablets generally provide 8–12 hours of relief per dose
- Prescription status: Available both by prescription and over-the-counter (OTC) in some regions and formulations
Benefits
- Effectively reduces inflammation at the site of pain, addressing the root cause rather than merely masking symptoms
- Provides significant relief from acute and chronic pain associated with osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis
- Topical formulations minimize systemic absorption, reducing the risk of gastrointestinal and cardiovascular side effects compared to oral NSAIDs
- Flexible dosing and formulation options allow for personalized treatment plans tailored to specific conditions and patient needs
- Rapid onset of action helps patients resume daily activities with improved mobility and comfort
- Non-opioid mechanism offers a valuable option for pain management without the risks of dependence or respiratory depression
Common use
Voltaren is commonly used for the management of mild to moderate pain and inflammation. Its oral forms are frequently prescribed for conditions such as osteoarthritis, rheumatoid arthritis, and acute gout flares. The topical gel is indicated for the treatment of actinic keratoses and pain associated with osteoarthritis in joints close to the skin surface, such as knees, hands, and elbows. The ophthalmic solution is used post-cataract surgery to reduce inflammation and pain. Off-label uses may include musculoskeletal pain, postoperative pain, and dysmenorrhea, though these should be guided by clinical evaluation.
Dosage and direction
Dosage varies significantly by formulation, indication, and patient factors. For oral tablets in adults, typical doses for osteoarthritis are 100–150 mg daily in divided doses. For rheumatoid arthritis, 150–200 mg daily in divided doses is common. Topical gel (1%) is applied 4 times daily to affected joints, with a total dose not exceeding 32 grams per day for all affected joints. For the 3% gel used in actinic keratoses, apply twice daily for 60–90 days. Ophthalmic solution is typically 1 drop 4 times daily beginning 24 hours post-surgery and continuing for 2 weeks. Always use the lowest effective dose for the shortest duration possible. Do not apply topical gel to open wounds, damaged skin, or under occlusive dressings unless directed. Wash hands after application unless treating hands.
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. Monitor renal function in patients with pre-existing kidney disease, heart failure, or liver cirrhosis, and in the elderly. Topical formulations still carry systemic absorption risk; avoid concurrent use with other oral NSAIDs. Do not apply to eyes, mucous membranes, or sunburned skin. Discontinue at first sign of rash or allergic reaction. Use sunscreen and protective clothing when using topical gel on sun-exposed areas due to photosensitivity risk. Pregnancy category C; avoid use in third trimester due to risk of premature closure of ductus arteriosus.
Contraindications
Hypersensitivity to diclofenac, aspirin, or other NSAIDs. History of asthma, urticaria, or allergic-type reactions after taking aspirin or other 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. Concomitant use with other NSAIDs, including COX-2 inhibitors.
Possible side effect
Common side effects include gastrointestinal discomfort, nausea, dyspepsia, diarrhea, and headache. Topical application may cause dryness, itching, rash, or irritation at the site. Serious side effects, though less common, include gastrointestinal bleeding or perforation, cardiovascular thrombotic events (myocardial infarction, stroke), hypertension, heart failure, renal injury, hepatotoxicity (elevated liver enzymes, jaundice), severe skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis), and anaphylactic reactions. Ophthalmic use may cause burning, stinging, itching, or blurred vision. Report any signs of bleeding, shortness of breath, chest pain, slurred speech, weakness, or yellowing of skin/eyes immediately.
Drug interaction
Concomitant use with other NSAIDs or aspirin increases risk of GI toxicity. May reduce effectiveness of ACE inhibitors, angiotensin II receptor blockers, and diuretics, and worsen heart failure or hypertension. Concurrent use with corticosteroids, anticoagulants (e.g., warfarin), antiplatelets (e.g., clopidogrel), or SSRIs increases bleeding risk. May increase levels of lithium, digoxin, and methotrexate. Cyclosporine and tacrolimus may enhance nephrotoxicity. Topical diclofenac may interact with other topically applied products. Consult a healthcare provider before starting any new medication.
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 catch up. For topical gel, apply the missed dose if remembered within a reasonable time, then resume the regular schedule. Do not apply more than the recommended amount in a 24-hour period. Consistency in application is important for maintaining therapeutic effect, particularly for chronic conditions.
Overdose
Symptoms of overdose may include nausea, vomiting, epigastric pain, gastrointestinal bleeding, drowsiness, dizziness, tinnitus, apnea, seizures, or coma. Hypertension, acute renal failure, and hepatotoxicity are possible. There is no specific antidote. Management is supportive and includes gastric lavage or activated charcoal if presented early, monitoring of vital signs, and symptomatic treatment. Hemodialysis is not effective due to high protein binding. For topical overdose, wash the area thoroughly and monitor for systemic symptoms. 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. Do not freeze. Keep oral tablets in their original container, tightly closed. Topical gel should be stored with the cap tightly closed. Keep all medications out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of unused medication properly according to local guidelines; do not flush down the toilet or pour into drainage.

Reviews
Voltaren is consistently rated highly by clinicians for its efficacy in managing inflammatory pain, with particular praise for its topical formulation’s favorable safety profile in appropriate patients. Many patients report significant improvement in joint mobility and pain reduction, especially with consistent use. Some note mild skin irritation with the gel, which often resolves with continued use. It remains a first-line recommendation in clinical guidelines for osteoarthritis and other inflammatory conditions due to its balanced efficacy and tolerability when used as directed.
