Severe knee pain in both legs can be caused by conditions like osteoarthritis, which involves joint cartilage breakdown leading to pain and stiffness. A medication called Orcerin Capsule, containing Diacerein, is used to reduce inflammation, pain, and swelling in such cases by helping repair cartilage.

• Orcerin Capsule should be taken exactly as prescribed by a doctor.
• Possible side effects include diarrhea, stomach pain, gas, or skin rash, which usually improve over time.
• Avoid alcohol while taking this medication to reduce the risk of liver damage.
• It is not recommended for children under 15, pregnant or breastfeeding individuals, and should be used cautiously in older adults.
• If side effects worsen or persist, or if you have allergies or other health concerns, consult a specialist such as a rheumatologist or orthopedic doctor.
