Generic Voltaren Sr Information

Introduction

Voltaren Sr is a non‑steroidal anti‑inflammatory drug (NSAID) formulated for oral administration. Its active ingredient is diclofenac, a potent inhibitor of prostaglandin synthesis. The medication belongs to the pain‑relief group and is used to alleviate inflammation‑driven discomfort in adult patients. In Hong Kong, diclofenac‑based products are listed on the Pharmacy and Poisons Ordinance and are widely prescribed for musculoskeletal conditions, postoperative pain, and certain inflammatory disorders.

What is Voltaren Sr?

Voltaren Sr is a tablet preparation that delivers a fixed dose of diclofenac sodium. The product is manufactured by Novartis International AG (the same company that markets the original Voltaren brand) and is registered with the Hong Kong Department of Health. It is positioned as a generic alternative to well‑known diclofenac brand names such as Voltaren, Cataflam, Zorvolex and Feldene. The formulation contains the same active compound, identical strength, and comparable bioavailability to the reference products, but is offered at a lower price point.

How Voltaren Sr Works

Diclofenac belongs to the arylacetic acid class of NSAIDs. It selectively inhibits cyclo‑oxygenase‑2 (COX‑2) and, to a lesser extent, COX‑1 enzymes. By blocking COX activity, diclofenac reduces the conversion of arachidonic acid to prostaglandins, which are mediators of inflammation, pain, and fever.

• Therapeutic effect: Lower prostaglandin levels diminish sensitisation of nociceptors, resulting in measurable pain relief within 30–60 minutes after oral intake.
• Onset and duration: Peak plasma concentrations occur around 1–2 hours; the anti‑inflammatory effect generally persists for 6–8 hours, allowing twice‑daily dosing for most indications.
• Clearance: Diclofenac is metabolised primarily by hepatic CYP2C9 and CYP3A4 pathways, with renal excretion of metabolites. The average elimination half‑life is 1–2 hours in healthy adults.

Conditions Treated with Voltaren Sr

• Osteoarthritis and rheumatoid arthritis – Diclofenac reduces joint swelling and pain, improving mobility in patients whose disease prevalence in Hong Kong is estimated at 5 % for OA and .5 % for RA.
• Ankylosing spondylitis – The drug controls axial inflammation and stiffness, a condition affecting roughly .1 % of the local adult population.
• Acute musculoskeletal injuries (sprains, strains, tendonitis) – Rapid analgesia enables earlier physiotherapy and functional recovery.
• Post‑operative pain – Short‑term use after orthopedic or dental surgery limits opioid requirements and enhances comfort.
• Dysmenorrhoea – Diclofenac’s antipyretic and analgesic actions relieve menstrual cramps, a common complaint among women of reproductive age in Hong Kong.

The drug is effective because it directly targets the inflammatory cascade that underlies these conditions, offering both analgesic and anti‑edematous benefits.

Who is Voltaren Sr For?

• Adults (≥18 years) with mild‑to‑moderate inflammatory pain who require oral NSAID therapy.
• Patients with osteoarthritis or rheumatoid arthritis who have not achieved adequate control with acetaminophen or topical agents.
• Individuals recovering from minor surgery or dental procedures where short‑term systemic anti‑inflammation is indicated.
• Active adults with sports‑related injuries who need rapid pain reduction to resume rehabilitation.

Contra‑indications / cautionary scenarios

• History of gastro‑intestinal ulceration, bleeding, or perforation.
• Severe hepatic or renal impairment (eGFR < 30 mL/min/1.73 m²).
• Uncontrolled hypertension or congestive heart failure, where NSAIDs may worsen fluid retention.
• Known hypersensitivity to diclofenac, other NSAIDs, or excipients in the tablet.
• Pregnant women in the third trimester (risk of premature closure of the fetal ductus arteriosus).

Patients meeting the above criteria should discuss dosage, duration, and monitoring requirements with a qualified health professional before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Gastro‑intestinal discomfort (dyspepsia, heartburn)
• Headache or dizziness
• Mild elevation of liver enzymes
• Fluid retention or peripheral oedema

Rare

• Peptic ulcer disease or gastrointestinal bleeding
• Skin reactions such as rash, photosensitivity, or Stevens‑Johnson syndrome (very rare)
• Hepatotoxicity manifested by jaundice or marked transaminase rise

Serious

• Myocardial infarction or stroke, especially with long‑term high‑dose use
• Severe renal impairment or acute kidney injury
• Anaphylactic reaction (airway obstruction, hypotension)

Clinically relevant drug‑drug interactions

• Anticoagulants (warfarin, direct oral anticoagulants) – increased bleeding risk.
• Other NSAIDs or aspirin – additive gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs) – heightened hemorrhagic potential.
• Lithium – diclofenac may raise serum lithium concentrations; monitor levels.
• Methotrexate – reduced renal clearance may lead to toxicity; dose adjustment may be required.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements, to avoid adverse interactions.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for adults: 50 mg of diclofenac sodium taken twice daily (every 12 hours) with food or a glass of milk to minimise gastric irritation.
• Maximum daily dose: 150 mg; exceeding this limit increases cardiovascular and gastrointestinal risks.

Missed dose

• If a dose is missed and the scheduled time is less than 6 hours away, take the missed tablet as soon as remembered.
• If the next dose is imminent, skip the missed tablet and resume the regular schedule. Do not double‑dose.

Overdose

• Symptoms may include nausea, vomiting, abdominal pain, drowsiness, or renal dysfunction.
• Seek immediate medical attention; supportive care (activated charcoal, gastric lavage) may be administered in a hospital setting.

Precautions

• Avoid concomitant alcohol intake, which can amplify gastrointestinal bleeding.
• Use the lowest effective dose for the shortest duration necessary.
• Patients with chronic kidney disease, heart failure, or uncontrolled hypertension require baseline and periodic monitoring of renal function, electrolytes, and blood pressure.

FAQ

• Is Voltaren Sr available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Voltaren, while Voltaren Sr is the generic formulation containing the same amount of diclofenac sodium. Both are registered with the Hong Kong Department of Health.

• What should I do if I travel abroad with Voltaren Sr?
  Carry the medication in its original packaging with a copy of the prescription or a doctor’s note if possible. Keep it in your hand luggage to avoid temperature extremes in the cargo hold, and ensure the container is sealed to prevent tampering.

• Does the tablet have a specific colour or imprint that helps identification?
  Voltaren Sr tablets are typically round, white to off‑white, and bear the imprint “50 MG” along with the manufacturer’s logo. The exact appearance may vary slightly between batches sourced from different licensed suppliers.

• Can Voltaren Sr be stored in a humid climate like Hong Kong’s summer?
  The tablets should be stored at a controlled room temperature of 20‑25 °C, protected from excess moisture. Use a tightly sealed container and avoid bathroom cabinets where humidity is high.

• Are there any special warnings for elderly patients using diclofenac?
  Older adults have an increased risk of gastrointestinal bleeding, renal impairment, and cardiovascular events with NSAIDs. Dose reduction, concurrent gastro‑protective agents, and regular monitoring are often recommended for this population.

• Is diclofenac detectable in standard drug‑testing panels?
  Diclofenac is not a controlled substance and is not screened for in typical employment or sports drug tests. However, specialized toxicology panels can identify its presence if specifically requested.

• How does Voltaren Sr differ from topical diclofenac gels?
  Oral diclofenac (Voltaren Sr) provides systemic anti‑inflammatory effects, suitable for deeper joint pain, whereas topical gels act locally on superficial tissues and have lower systemic absorption, reducing the risk of systemic adverse events.

• What clinical trials supported the approval of diclofenac for rheumatoid arthritis?
  Large‑scale, double‑blind, placebo‑controlled studies conducted in the 199s demonstrated that 50 mg twice daily of diclofenac reduced tender joint counts and improved patient‑reported pain scores significantly compared with placebo. These data underlie current guideline recommendations.

• Can I take Voltaren Sr with a low‑dose aspirin regimen for heart protection?
  Co‑administration increases the risk of gastrointestinal bleeding. If low‑dose aspirin is medically required, discuss gastro‑protective strategies (e.g., proton‑pump inhibitor) with your healthcare provider before adding diclofenac.

• Does the formulation contain any allergens such as lactose or gluten?
  In the standard tablet, inactive ingredients include microcrystalline cellulose, starch, magnesium stearate, and silicon dioxide. No lactose or gluten is listed, but patients with severe sensitivities should review the full excipient list provided by the supplier.

• What are the legal limits for personal import of diclofenac into Hong Kong?
  Hong Kong customs permits a 30‑day supply for personal use without a prescription, provided the medication is for the importer's own consumption and is accompanied by a copy of a valid prescription or a physician’s statement.
