Product Overview

Reactin SR is a sustained-release medication containing the active ingredient Diclofenac. It belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs) and is formulated to provide extended pain relief and inflammation control. Unlike immediate-release formulations, It is designed to release the medication gradually over time, allowing for less frequent dosing and consistent symptom management. It is available in tablet form and is commonly prescribed for the treatment of chronic inflammatory conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and other musculoskeletal disorders.


Reactin SR is indicated for the management of chronic pain and inflammation associated with various conditions, including arthritis, gout, sprains, strains, and menstrual cramps. It is particularly useful for individuals who require long-term symptom control and prefer the convenience of once-daily dosing. Reactin SR helps to improve joint function, reduce stiffness, and enhance mobility, allowing patients to maintain an active lifestyle with greater comfort and ease.

How to Use

Reactin SR tablets should be swallowed whole with a full glass of water, preferably with food to minimize the risk of gastrointestinal side effects. Do not crush, chew, or break the tablets, as this may interfere with the sustained-release mechanism. Take it exactly as prescribed by your healthcare provider, and do not exceed the recommended dosage or duration of treatment without consulting your doctor.

How it Works

Reactin SR works by inhibiting the activity of cyclooxygenase enzymes (COX-1 and COX-2), which are involved in the synthesis of prostaglandins, hormone-like substances that promote inflammation, pain, and fever. By blocking the production of prostaglandins, it helps to reduce inflammation, alleviate pain, and improve joint function. The sustained-release formulation ensures a steady and prolonged release of the medication, providing extended symptom relief over time.

Dosage and Administration

The recommended dosage of Reactin SR varies depending on the severity of the condition being treated and the individual patient’s response to therapy. Typically, the initial dose is one tablet taken once daily, with a maximum daily dose of 150 mg for most adults. Your doctor may adjust the dosage based on your specific needs and medical history. It is important to take it at the same time each day to maintain consistent blood levels of the medication.


Reactin SR offers several benefits for individuals with chronic inflammatory conditions. Its sustained-release formulation provides long-lasting pain relief and inflammation control, allowing for once-daily dosing and improved medication adherence. By reducing inflammation and alleviating pain, Reactin SR helps to enhance joint function, mobility, and overall quality of life for patients with arthritis and related disorders.

Common Side Effects

Common side effects of Reactin SR may include gastrointestinal disturbances such as nausea, indigestion, diarrhea, and abdominal pain. Other potential side effects include headache, dizziness, drowsiness, rash, and fluid retention. Long-term use of it may increase the risk of gastrointestinal ulcers, bleeding, and kidney damage. If you experience severe or persistent side effects, contact your healthcare provider promptly.


Before using it, inform your healthcare provider if you have a history of gastrointestinal ulcers, bleeding disorders, kidney or liver disease, heart failure, or high blood pressure. Avoid using it if you are allergic to diclofenac or other NSAIDs, or if you have a history of asthma attacks, urticaria, or other allergic reactions after taking aspirin or other NSAIDs. Use Reactin SR with caution in elderly patients, as they may be more susceptible to side effects.
