About Voltaren
Voltaren (Generic Voltaren (Diclofenac)) is a widely used oral non-steroidal anti-inflammatory drug (NSAID) that belongs to the arylacetic acid class. It contains the active ingredient diclofenac potassium, which reduces pain and inflammation by blocking cyclo-oxygenase enzymes that generate prostaglandins. In Singapore, the 50 mg and 100 mg tablets are prescription-only medicines indicated for conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, mild-to-moderate musculoskeletal pain, postoperative discomfort, and dysmenorrhea. The medication is often chosen when patients need rapid relief-clinical studies show appreciable pain reduction within 30 minutes of the first dose.
What is Generic Voltaren (Diclofenac)?
Generic Voltaren (Diclofenac) is the brand-named formulation of the generic NSAID diclofenac potassium. It is marketed by Novartis, a globally recognized pharmaceutical company, and is approved by Singapore’s Health Sciences Authority (HSA) for oral use in tablet form. The drug falls under the category of pain-relief and anti-inflammatory agents and is classified as a prescription-only medication in the country. Its therapeutic profile is supported by extensive clinical trials that demonstrate efficacy comparable to other NSAIDs while offering a slightly faster onset of action.
How Voltaren Works
Voltaren exerts its effect primarily by inhibiting cyclo-oxygenase-2 (COX-2) and, to a lesser extent, COX-1 enzymes. By curbing the synthesis of prostaglandins, it diminishes peripheral sensitisation of nociceptors and reduces vascular permeability, which together lessen pain perception and swelling. After oral ingestion, diclofenac is rapidly absorbed; peak plasma concentrations are reached within 1 hour for the 50 mg tablet and 1.5 hours for the 100 mg tablet. The drug is extensively bound to plasma proteins (≈99 %) and undergoes hepatic metabolism via CYP2C9, with a terminal half-life of 1-2 hours. These pharmacokinetic features explain why a single dose can provide relief for up to 8 hours, making once- or twice-daily dosing practical for most patients.
Why Voltaren is Used for Pain Relief and Inflammation Conditions
- Osteoarthritis: Diclofenac reduces joint inflammation by limiting prostaglandin-mediated cartilage breakdown, aligning with the American College of Rheumatology recommendations for NSAID therapy as a first-line option.
- Rheumatoid arthritis: By dampening COX-2 activity, Voltaren alleviates synovial inflammation, contributing to decreased joint tenderness and stiffness-a benefit documented in long-term safety studies.
- Ankylosing spondylitis: The drug’s ability to suppress inflammatory cytokines helps control axial spine pain, supporting its place in the European League Against Rheumatism (EULAR) treatment algorithm.
- Post-operative pain: A single pre-operative dose can lower opioid requirements, as demonstrated in randomized trials where diclofenac reduced morphine consumption by up to 30 %.
- Dysmenorrhea: By targeting uterine prostaglandin production, Voltaren provides rapid menstrual cramp relief, often outperforming ibuprofen in head-to-head comparisons for pain intensity scores.
Off-Label and Investigational Uses of Voltaren
Studies have explored diclofenac for neuropathic pain and migraine prophylaxis, but these indications lack approval from Singapore’s HSA. Evidence remains limited to small-scale trials, and the drug’s safety profile in these contexts is not well established. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Voltaren Right for You?
Voltaren suits adults who need swift control of moderate pain or inflammation and can tolerate NSAIDs. It is generally appropriate for patients without a history of gastrointestinal ulceration, uncontrolled hypertension, or severe renal impairment. Pregnant or breastfeeding individuals should avoid diclofenac because of potential fetal cardiovascular effects. Elderly patients may require dose adjustment, as age-related decline in renal function can increase plasma concentrations. As always, the prescribing clinician will weigh these factors against the therapeutic benefits before recommending therapy.
Taking Voltaren Effectively
- Timing: Take the tablet with a full glass of water, preferably after a meal to minimise gastric irritation.
- Food interactions: High-fat meals do not markedly affect absorption, but co-administration with alcohol should be avoided because of additive gastrointestinal risk.
- Missed dose: If a dose is forgotten, take it as soon as you remember unless the next scheduled dose is within 6 hours; in that case, skip the missed tablet and resume the regular regimen.
- Travel tips: Carry the medication in its original packaging, and keep it in a temperature-controlled environment (15-30 °C).
Understanding Side Effects and How to Manage Them
- Gastrointestinal discomfort: The inhibition of COX-1 reduces protective mucosal prostaglandins, leading to dyspepsia or heartburn. Take Voltaren with food, use a proton-pump inhibitor if prescribed, and report persistent pain.
- Headache or dizziness: These central nervous system effects stem from prostaglandin alteration within the brain. Hydration and avoiding rapid position changes can help.
- Renal considerations: Reduced renal prostaglandin synthesis may impair kidney perfusion, especially in patients with dehydration or pre-existing renal disease. Ensure adequate fluid intake and monitor renal function if long-term therapy is required.
- Serious reactions: Although rare, signs such as severe abdominal pain, black stools, or sudden swelling of the face or limbs warrant immediate medical attention, as they may indicate ulceration or an allergic response.

Frequently Asked Questions
-
What differentiates Voltaren from other NSAIDs like ibuprofen? Voltaren has a slightly higher COX-2 selectivity, which can translate to more potent anti-inflammatory action and a faster onset of analgesia, especially at the 100 mg dose.
-
Can I take Voltaren with aspirin for cardiovascular protection? Concurrent use may increase the risk of gastrointestinal bleeding; discuss alternative strategies with your clinician.
-
Is it safe to use Voltaren for more than a week? Short-term use (up to 7 days) is well-tolerated for most adults. Prolonged therapy should be monitored for renal and hepatic function, and only continue under medical supervision.
-
Will Voltaren affect my blood pressure? NSAIDs can cause sodium retention and diminish the efficacy of antihypertensive drugs. If you have hypertension, your doctor may recommend regular blood pressure checks while on the medication.
-
How does Voltaren compare to topical diclofenac gels? Oral tablets provide systemic pain relief suitable for deep-seated joint inflammation, whereas topical gels are better for localized superficial pain with a lower systemic side-effect profile.
-
Can I purchase Voltaren without a prescription in Singapore? No. Oral Voltaren tablets are classified as prescription-only. Our online pharmacy facilitates authorized prescribing and delivery after verification.
-
What should I do if I experience skin rash after taking Voltaren? Discontinue the medication and seek medical advice promptly, as rashes may indicate an allergic reaction.
-
Is it okay to take Voltaren on an empty stomach? Taking the tablet without food increases the risk of gastric irritation. It is advisable to ingest it with or after a meal.
-
Does Voltaren interact with blood thinners? Both agents can impair platelet function, raising bleeding risk. Coordinate with your healthcare provider before combining them.
-
Can Voltaren be used for migraine relief? While some studies suggest modest benefit, diclofenac is not approved for migraine prophylaxis in Singapore, and other agents are preferred.
