Introduction About FLEXURA D TABLET

Flexura D Tablet contains diclofenac and metaxalone. It is prescribed for the management of pain associated with muscle spasms. Diclofenac helps reduce pain and inflammation, while metaxalone acts on the central nervous system to relax muscles. This combination may help ease muscle discomfort and support improved movement. Use Flexura D Tablet only for the condition and duration prescribed by your doctor.

Take Flexura D Tablet exactly as prescribed by your doctor. Follow the recommended dose and timing and take it with food if advised to help reduce stomach discomfort. Avoid driving or operating machinery if you experience drowsiness or dizziness and avoid alcohol because it may increase these effects. Do not change the dose or stop taking the medicine without medical advice.

Do not take Flexura D Tablet if you are allergic to diclofenac, metaxalone, or any of its ingredients. Before starting the medicine, inform your doctor if you have a history of stomach ulcers or bleeding, kidney or liver problems, heart disease, high blood pressure, asthma, or an allergy to painkillers such as aspirin or other NSAIDs. Tell your doctor about all medicines you are taking, particularly other painkillers, sedatives, or medicines that may cause drowsiness, as these may increase the risk of side effects or interactions.

Common side effects of Flexura D Tablet may include nausea, vomiting, stomach discomfort, heartburn, diarrhoea, dizziness, or drowsiness. Seek medical advice if you experience severe or persistent symptoms. Stop taking the medicine and seek urgent medical help if you develop signs of a serious allergic reaction, difficulty breathing, chest pain, black stools, vomiting blood, or severe stomach pain.

Benefits of FLEXURA D TABLET

Warning & Precautions

Pregnancy

Consult your doctor

Flexura D Tablet should be used during pregnancy only when specifically advised by a healthcare professional. Diclofenac can pose risks during pregnancy, particularly from around 20 weeks onward, and should generally be avoided in late pregnancy. Consult your doctor before taking this medicine if you are pregnant or planning a pregnancy.

Breastfeeding

Consult your doctor

Inform your doctor if you are breastfeeding before taking Flexura D Tablet. Your healthcare professional can assess whether this combination is appropriate and recommend an alternative if necessary. 

Driving and Using Machines

Use with Caution

Flexura D Tablet may cause dizziness, sleepiness, or reduced alertness. Avoid driving, cycling, or operating machinery if you experience these effects. 

Alcohol

Contraindicated

Avoid alcohol while taking Flexura D Tablet. Alcohol may increase drowsiness and may also increase the risk of stomach irritation or bleeding associated with diclofenac.

Kidney

Use with Caution

Inform your doctor if you have kidney disease, reduced kidney function, or a history of kidney problems. Diclofenac may affect kidney function, and metaxalone requires caution in renal impairment. Your doctor will determine whether this medicine is suitable for you.

Liver

Consult your doctor

Tell your doctor if you have liver disease or abnormal liver function. Diclofenac can cause liver-related adverse effects, and metaxalone should be used cautiously in mild to moderate hepatic impairment. Severe hepatic impairment is a contraindication to metaxalone use.

Allergy

Contraindicated

Do not take Flexura D Tablet if you are allergic to diclofenac, metaxalone, or any of its ingredients. Tell your doctor if aspirin or another NSAID has previously caused you wheezing, asthma symptoms, swelling, or an allergic reaction.

Heart Disease

Consult your doctor

Inform your doctor if you have high blood pressure, heart disease, heart failure, a previous heart attack or stroke, or fluid retention. Diclofenac may increase cardiovascular risks and can worsen fluid retention in some patients. Your doctor should assess whether it is appropriate for you. 

Use In Pediatrics

Consult your doctor

Flexura D Tablet should be given to children only if specifically prescribed by a qualified healthcare professional. The safety and suitability of the fixed-dose combination should be assessed for the child's age and condition. 

Use In Geriatrics
