Diclofenac Sodium Voltaren Medications

Diclofenac Sodium Info

What is Diclofenac Sodium?

Diclofenac Sodium is a non-steroidal anti-inflammatory drug (NSAID) that reduces inflammation and eases pain. It works by blocking substances in the body that cause swelling and discomfort. In Hong Kong, Diclofenac Sodium is available in several medicines, including oral tablets and topical gels.

Medicines that contain Diclofenac Sodium

A number of products on the Hong Kong market use Diclofenac Sodium as the active ingredient.

• Voltaren - sold as tablets, capsules and a gel for external use.
• Diclofenac - the generic name appears on many store-brand tablets and capsules.
• Voveran Gel - a clear, skin-applied gel formulated for local pain relief.

These medicines come in different strengths, such as 25 mg, 50 mg or 75 mg tablets, and the gels typically contain 1 % or 2 % Diclofenac Sodium. All are registered with the Hong Kong Department of Health and listed in the local Medicines Registry.

Conditions Diclofenac Sodium helps with

Diclofenac Sodium is commonly used for several painful or inflammatory conditions:

• Osteoarthritis - a long-term joint condition that causes stiffness and aching, especially in the knees, hips and hands.
• Rheumatoid arthritis - an autoimmune disease that produces swelling and joint pain.
• Ankylosing spondylitis - a form of arthritis that mainly affects the spine.
• Acute musculoskeletal injuries - such as sprains, strains or bruises that occur after sports or everyday activities.
• Post-operative pain - discomfort that follows minor surgical procedures.
• Dysmenorrhoea - painful menstrual cramps that affect many women.

These uses are approved by Hong Kong health authorities and reflect the medicine’s ability to lessen swelling and improve comfort.

How Diclofenac Sodium works

When you take a Diclofenac Sodium product, the drug interferes with chemicals called prostaglandins that trigger inflammation. By reducing prostaglandin production, the medication eases swelling and dulls the sensation of pain. Topical gels deliver the same effect directly to the skin over the painful area, so the relief can be felt more quickly.

Safety and side effects

Common side effects

Most people experience only mild, short-lasting reactions, such as:

• Stomach upset or mild heartburn.
• Headache or slight dizziness.
• Minor skin irritation where a gel is applied.

These symptoms usually disappear on their own or with simple measures like taking the medicine with food.

Serious reactions

Rarely, Diclofenac Sodium can cause more severe problems. Seek immediate medical help if you notice:

• Difficulty breathing or swelling of the face, lips or throat.
• Sudden, severe stomach pain or black-tarry stools, which may signal bleeding.
• Unexplained bruising, bleeding gums or pink-coloured urine.

Who should be cautious

People with certain health conditions should discuss the use of Diclofenac Sodium with a health professional before starting any product that contains it:

• A history of stomach ulcers or gastrointestinal bleeding.
• Heart failure, uncontrolled high blood pressure or a recent heart attack.
• Severe kidney or liver disease.
• Pregnancy, especially in the third trimester, and breastfeeding.
• Known allergy to Diclofenac or other NSAIDs.

Interaction awareness

Diclofenac Sodium can interact with other medicines and lifestyle choices. Keep these points in mind:

• Avoid taking two NSAIDs at the same time (e.g., ibuprofen) unless directed.
• Anticoagulants such as warfarin may increase bleeding risk.
• Certain blood-pressure medicines (like ACE inhibitors) can be affected.
• Alcohol can heighten stomach irritation.
• Sun exposure may be a concern when using topical gels; protect the treated skin.

For a full list of possible interactions, refer to the information sheet that comes with each specific product.

Things to keep in mind

Store Diclofenac Sodium tablets in a dry place at room temperature, away from direct sunlight. Gels should be kept in the original tube and sealed tightly after each use. Most oral forms are intended for short-term relief of acute pain, while chronic conditions may be managed under professional supervision. Remember that each brand-Voltaren, generic Diclofenac, Voveran Gel-has its own instructions for use; always follow the label that accompanies your chosen product.
