Diclofenac serves as a non-steroidal anti-inflammatory drug for pain relief. Decreasing prostaglandin synthesis within the body lowers physiological signaling and local focal area swelling.
Diclofenac belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs). It works by reducing the production of prostaglandins, chemicals that cause pain and swelling. In Singapore, this active compound is included in several preparations such as tablets, topical gels and patches. The molecule is identified by the International Nonproprietary Name (INN) Diclofenac and is recognised for its role in managing musculoskeletal discomfort.
Diclofenac appears in a range of products, notably the gels Voveran Gel and Voltaren Gel. These topical options are applied directly to the skin over the affected area, delivering the drug locally while limiting systemic exposure. Oral tablets and capsules are also available, providing a convenient route for deeper joint or muscle complaints. Whether supplied as a brand name or a generic version, the ingredient remains the same, though strength and excipients may differ.
The compound is commonly employed to address:
Its anti-inflammatory effect helps lessen swelling, which can improve mobility for adults and older adults who experience joint degeneration. Patients with sports-related injuries also often turn to Diclofenac-based products for short-term relief.
When taken, Diclofenac blocks an enzyme needed for prostaglandin synthesis. With fewer prostaglandins circulating, the body’s pain signals are dampened and inflammation subsides. In the gel form, the drug penetrates the skin and reaches underlying tissues, providing a focused effect without the higher blood levels seen with oral administration.
Mild skin irritation, such as itching or redness, may appear where a gel is applied. Some users report a transient feeling of warmth at the application site. Oral use can occasionally cause minor stomach upset or nausea, which usually resolves without intervention.
Although rare, severe skin reactions like blistering or swelling of the face should be treated as emergencies. Signs of gastrointestinal bleeding-dark stools or vomiting of blood-also require prompt medical attention. Any sudden shortness of breath or swelling of the limbs warrants immediate evaluation.
People with known hypersensitivity to Diclofenac or other NSAIDs should avoid products containing this substance. Caution is advised for those with a history of ulcer disease, heart failure, or severe kidney impairment. Pregnant individuals, particularly in the third trimester, are generally advised against using NSAIDs.
Alcohol consumption can increase the risk of stomach irritation when combined with Diclofenac. Concomitant use of blood-thinning agents, certain antihypertensives, or other NSAIDs may heighten the chance of adverse effects. Detailed interaction lists are available on the information leaflets of each specific medication.
Storage of gels should be in a cool, dry place away from direct sunlight; tablets should remain in their original container to protect against moisture. Treatment length varies: topical gels are often used for several days to a few weeks, while oral forms may be prescribed for a limited period during flare-ups. For precise dosing instructions, strength details, and duration guidance, refer to the labeling of the individual product.
