Generic Voltaren Information

Introduction

Voltaren is a non‑steroidal anti‑inflammatory drug (NSAID) marketed in Hong Kong for the relief of mild to moderate pain and inflammation. Its active compound, diclofenac, belongs to the phenylacetic acid class of NSAIDs and is widely used worldwide. The medication is manufactured by several pharmaceutical companies; in Hong Korea the most common commercial version is produced by GlaxoSmithKline (GSK). In addition to its primary indication for musculoskeletal pain, diclofenac is approved for the treatment of osteoarthritis, rheumatoid arthritis, dysmenorrhoea, and certain postoperative pain states.

What is Voltaren?

Voltaren is a brand‑name formulation that contains the single active ingredient diclofenac sodium (or diclofenac potassium in some oral tablets). It is classified as an oral NSAID, available as conventional tablets, modified‑release tablets, and topical gels. The product was first introduced in the United Kingdom in the 197s and has since been marketed in more than 100 countries. In Hong Kong the drug is regulated by the Department of Health under the Pharmacy and Poisons Ordinance and is sold both by local pharmacies and licensed online distributors.

How Voltaren Works

Diclofenac exerts its therapeutic effect by reversibly inhibiting cyclooxygenase‑1 (COX‑1) and cyclo‑oxygenase‑2 (COX‑2) enzymes. These enzymes catalyse the conversion of arachidonic acid to prostaglandins, which are mediators of inflammation, pain, and fever. By reducing prostaglandin synthesis, diclofenac lowers the sensitivity of nociceptors (pain‑sensing nerves) and diminishes inflammatory swelling. Oral diclofenac is rapidly absorbed, with peak plasma concentrations typically reached within 1–2 hours. The drug’s elimination half‑life ranges from 1 to 2 hours, but its anti‑inflammatory activity persists longer due to tissue binding. The onset of analgesia is usually felt within 30 minutes, and therapeutic effect can last up to 6 hours, depending on the dose and formulation.

Conditions Treated with Voltaren

• Osteoarthritis (OA) – OA prevalence in Hong Kong adults over 60 is estimated at 12–15 %. Diclofenac reduces joint pain and improves functional capacity, often as part of a step‑wise analgesic regimen.
• Rheumatoid arthritis (RA) – Approximately .4 % of the Hong Kong population has RA. Diclofenac provides rapid symptom relief while disease‑modifying agents take effect.
• Acute musculoskeletal sprains and strains – Sports‑related injuries are common among Hong Kong’s active adult population; diclofenac limits inflammation and enables earlier mobilisation.
• Dysmenorrhoea – Primary menstrual pain affects up to 80 % of women of reproductive age. A short course of diclofenac offers effective analgesia with fewer gastrointestinal side effects than older NSAIDs.
• Post‑operative pain (minor surgery) – For procedures such as dental extractions or arthroscopic debridement, diclofenac is recommended as part of multimodal analgesia to minimise opioid use.

Who is Voltaren For?

• Adults with intermittent or chronic nociceptive pain where inflammation contributes to symptom severity (e.g., knee OA, low‑back strain).
• Patients requiring short‑term analgesia after minor surgery or during menstrual periods.
• Individuals who can tolerate NSAIDs without a history of peptic ulcer disease, severe renal impairment, or uncontrolled hypertension.
• Patients not currently using anticoagulants such as warfarin, unless closely monitored, because diclofenac can increase bleeding risk.

Contra‑indications include known hypersensitivity to diclofenac or any other NSAID, active gastrointestinal ulceration, severe heart failure (NYHA class III–IV), and the third trimester of pregnancy. Caution is advised for older adults (>65 years), those with mild‑to‑moderate kidney or liver disease, and patients with a history of cardiovascular events.

Risks, Side Effects, and Interactions

Common

• Gastro‑intestinal discomfort (dyspepsia, nausea)
• Headache
• Dizziness
• Elevated blood pressure

Rare

• Peptic ulceration or gastrointestinal bleeding
• Hepatic enzyme elevation (ALT, AST)
• Dermatologic reactions such as photosensitivity or mild rash

Serious

• Myocardial infarction or stroke, particularly with high‑dose or long‑term use
• Severe renal impairment or acute kidney injury
• Severe hypersensitivity reactions (e.g., Stevens‑Johnson syndrome, anaphylaxis)
• Gastro‑intestinal perforation

Clinically Relevant Drug–Drug Interactions

• Anticoagulants/Antiplatelet agents (e.g., warfarin, clopidogrel) – increased bleeding risk.
• Selective serotonin‑reuptake inhibitors (SSRIs) – additive risk of upper gastrointestinal bleeding.
• Angiotensin‑converting enzyme (ACE) inhibitors, ARBs, diuretics – potential reduction in renal perfusion, especially in dehydrated patients.
• Lithium – NSAIDs may raise serum lithium concentrations; monitor levels.
• Methotrexate – diclofenac can reduce renal clearance of methotrexate, raising toxicity risk.

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dosing for most indications: 50 mg diclofenac sodium taken twice daily (total 100 mg/day). For acute pain, a single dose of 75 mg may be prescribed, not exceeding 150 mg per day.
• Modified‑release tablets are usually taken once daily with the same total daily amount.
• Topical gel (1 % or 2 % w/w) is applied to the affected area 3–4 times daily; systemic absorption is minimal.

Missed dose: If a scheduled dose is forgotten and the next dose is more than 6 hours away, take the missed dose. If the next dose is imminent, skip the missed dose and resume the regular schedule; do not double‑dose.

Overdose: Symptoms may include nausea, vomiting, abdominal pain, dizziness, or severe bleeding. If overdose is suspected, seek immediate medical attention; activated charcoal may be administered in the emergency department.

Precautions:

• Take tablets with food or a full glass of water to minimise gastric irritation.
• Avoid alcohol, which can exacerbate gastrointestinal and hepatic toxicity.
• Patients with hypertension should monitor blood pressure regularly.
• Renal function should be assessed before initiating therapy in elderly or comorbid patients.

FAQ

• Is Voltaren available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Voltaren, while multiple generic manufacturers produce diclofenac tablets that contain the same active ingredient. Generic versions are typically less expensive and are approved by the Hong Kong Department of Health.

• What does the packaging of Voltaren tablets look like?
  In Hong Kong, Voltaren tablets are commonly supplied in blister packs of 10 or 30 tablets, each tablet being white, round, and scored for easy splitting. The packaging displays the diclofenac dosage, batch number, expiry date, and regulatory warnings in both English and Chinese.

• Can Voltaren be stored outside the refrigerator?
  Yes. Diclofenac tablets should be kept at controlled room temperature (15 °C–30 °C), away from direct sunlight, moisture, and heat sources. The topical gel also requires room‑temperature storage but must be sealed tightly to prevent evaporation.

• Are there any special travel considerations for Voltaren?
  When travelling, keep the medication in its original packaging with a copy of the prescription or a pharmacist’s note if required by customs. Ensure the container is not exposed to extreme temperatures, such as the cabin of an aircraft during long flights.

• How does diclofenac differ from older NSAIDs like ibuprofen?
  Diclofenac is more potent on a milligram‑to‑milligram basis and has a longer plasma half‑life, allowing twice‑daily dosing for many indications. However, it carries a slightly higher cardiovascular risk profile compared with ibuprofen, which should be considered in patients with existing heart disease.

• What clinical trial established the efficacy of diclofenac for osteoarthritis?
  A pivotal double‑blind, placebo‑controlled study published in The Lancet (1995) demonstrated that diclofenac 50 mg twice daily significantly reduced pain scores and improved joint function over a 12‑week period in patients with knee osteoarthritis.

• Is there a known interaction between diclofenac and traditional Chinese herbs?
  Certain herbs, such as Ginkgo biloba and Angelica sinensis, possess antiplatelet properties and may increase bleeding risk when combined with diclofenac. Patients should disclose all herbal supplements to their healthcare provider before starting therapy.

• Do any drug‑testing programs flag diclofenac as a prohibited substance?
  Diclofenac is not listed on the World Anti‑Doping Agency (WADA) prohibited list. However, athletes competing under strict federation rules should verify status with their governing body, as some competitions may have specific restrictions on NSAID use.

• What is the shelf‑life of Voltaren tablets after opening the blister pack?
  Once a blister pack is opened, tablets remain stable for up to 12 months if kept in a dry, cool environment. The expiration date printed on the pack should be observed, and any tablets that appear discoloured or crumbly should be discarded.

• How does the topical Voltaren gel compare to oral diclofenac in terms of systemic exposure?
  Topical application results in roughly 5–10 % of the systemic exposure seen with oral dosing, reducing the risk of gastrointestinal and cardiovascular side effects while still providing localized pain relief for conditions such as osteoarthritis of the knee or hand.

• Are there any pediatric formulations of diclofenac approved in Hong Kong?
  Pediatric oral suspensions of diclofenac are approved for children over 6 years of age for short‑term pain relief, but the adult Voltaren tablets are not indicated for children. Dosage for children is weight‑based and must be prescribed by a pediatrician.
