Reactin 100 SR Tablet

Reactin 100 SR Tablet is a prescription pain-relief medicine that contains diclofenac 100 mg in each sustained-release tablet. Diclofenac belongs to the nonsteroidal anti-inflammatory drug (NSAID) class, which helps reduce pain, swelling, and stiffness. Reactin 100 SR Tablet is used for conditions such as arthritis and other painful inflammatory conditions when a longer-acting diclofenac tablet is appropriate.

How it works: Diclofenac works by blocking substances in the body called prostaglandins that cause pain, swelling, and inflammation. In Reactin 100 SR Tablet, the sustained-release tablet slowly releases diclofenac over time to help maintain longer-lasting relief.

Reactin 100 SR Tablet is a higher-strength, sustained-release diclofenac tablet, so it is generally used when a doctor wants longer-lasting pain relief rather than a quick-acting dose. Because it releases diclofenac slowly, it may feel different from immediate-release tablets and is not meant to be split, crushed, or used as a starter dose without medical guidance.

• Arthritis pain and swelling
• Muscle and joint pain
• Back pain

• Swallow Reactin 100 SR Tablet whole with a glass of water.
• Do not crush, chew, or split the sustained-release tablet.
• Take it exactly as prescribed, usually at the same time each day if your doctor directs once-daily use.
• Taking it with food or milk may help reduce stomach upset.
• Use the lowest effective dose for the shortest time your doctor recommends.
• Do not take extra tablets for breakthrough pain unless your doctor tells you to.

Each Reactin 100 SR Tablet contains diclofenac 100 mg. Because this is a higher-strength sustained-release tablet, the dose and how often you take it must be decided by your doctor; it is commonly prescribed once daily, and you should not exceed the maximum daily dose set by your prescriber. Do not use more than directed, since higher NSAID doses can increase the risk of stomach bleeding, kidney problems, and heart-related side effects.

Do not change your dose or stop the medicine without speaking to your doctor.
