Avonac SR 100mg Tablet

Avonac SR 100mg Tablet contains Diclofenac Sodium 100mg in a sustained-release (SR) formulation, a non-steroidal anti-inflammatory drug (NSAID) designed to release the active ingredient gradually over an extended period, allowing for convenient once-daily dosing while maintaining consistent pain and inflammation control throughout the day.

This medicine is used to relieve pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute musculoskeletal injuries, and other painful inflammatory conditions. Because oral NSAIDs at this strength carry risks that require medical assessment and monitoring, Avonac SR 100mg Tablet is classified as a prescription (Rx) medicine in Malaysia, and it should only be used following an online consultation through DoctorOnCall so a doctor can confirm suitability, check for contraindications, and issue a prescription before dispensing.

Diclofenac works by inhibiting cyclo-oxygenase (COX) enzymes, which are responsible for producing prostaglandins, chemical mediators involved in pain, inflammation, and fever. By reducing prostaglandin production, diclofenac helps to relieve pain and swelling associated with inflammatory joint and musculoskeletal conditions. The sustained-release formulation allows the medicine to be released steadily, providing round-the-clock symptom control with a single daily dose.

Take Avonac SR 100mg Tablet as prescribed by your doctor, swallowing the tablet whole with a full glass of water, preferably with food or after meals to reduce the risk of stomach upset. Do not crush, break, or chew the tablet, as this can affect the sustained-release mechanism and increase the risk of side effects. Take at the same time each day for consistent symptom relief.

The typical adult dose prescribed is one tablet (100mg) taken once daily, although your doctor may adjust the dose based on your condition, response to treatment, and risk factors for NSAID-related side effects. The lowest effective dose for the shortest duration necessary is generally recommended, and long-term use should be reviewed periodically by your prescribing doctor.

Avonac SR 100mg Tablet should be used within the shelf-life period printed on the packaging when stored under the recommended conditions. Do not use the tablets after the expiry date shown on the box or blister strip.

Store below 30°C in a cool, dry place away from direct sunlight and moisture. Keep the tablets in their original blister packaging until ready for use, and keep out of reach of children.
