Product introduction
Flexon MR Tablet is a three-in-one medicine that brings together two pain relievers and a muscle relaxant to tackle pain caused by muscle spasm. It is commonly prescribed for stiff, cramping or overworked muscles, easing both the pain and the tightness so that movement becomes more comfortable. It can be used on its own or with other treatments, and is best taken with food to protect the stomach. Because it is a prescription combination, the dose and length of the course should follow your doctor's instructions exactly and not be stretched beyond what is advised.
Storage: Store below 25°C. Keep in the original container, tightly closed and out of the reach of children.
Uses of Flexon MR Tablet

Benefits of Flexon MR Tablet
Flexon MR is designed to relieve pain, swelling and inflammation in conditions that affect the muscles. The ibuprofen and paracetamol work together to block the chemical signals that produce pain and fever, while chlorzoxazone relaxes tense muscles by acting on the nerves in the brain and spinal cord. The overall effect is less muscle stiffness and spasm, reduced pain, and easier, freer movement, helping you return to normal daily activity more quickly.
Side effects of Flexon MR Tablet
Most side effects do not require medical attention and go away as your body adjusts. Consult your doctor if they persist.

- Indigestion
- Stomach pain

How to use Flexon MR Tablet
Swallow the tablet whole with water; do not chew, crush or break it. Take it with or after food to lower the chance of stomach upset. Stick to the dose and schedule your doctor has set.
How Flexon MR Tablet works
The tablet combines three actions. Ibuprofen and paracetamol reduce pain and inflammation by blocking the chemical messengers (prostaglandins) responsible for pain, swelling and fever. Chlorzoxazone is a muscle relaxant that works on the central nervous system to calm muscle spasm and stiffness, which further eases discomfort.
