Hilin capsule (Diacerein) is a medicine used for the long-term management of knee pain caused by osteoarthritis, a condition in which the knee joint wears out over time. It works slowly to reduce pain and improve joint function. There is no exact direct substitute with the same action, but several other options may be used depending on your symptoms and overall health. For pain relief, paracetamol is often used as a first choice. Non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen, may also help reduce pain and swelling, but they should only be taken after medical advice, especially in people with acidity, kidney problems or heart conditions. A diclofenac gel applied to the knee can provide local relief with fewer side effects compared to tablets. Some people may also consider glucosamine supplements, although the benefit can vary from person to person. In some cases, doctors may also suggest physiotherapy, weight control, and knee-strengthening exercises, all of which are very important for long-term improvement. It is best to consult your doctor before changing or stopping any medications.
