Alonac P Tablet is a commonly prescribed medicine used to relieve pain and inflammation. It typically contains aceclofenac (a non-steroidal anti-inflammatory drug) and paracetamol, which work together to reduce swelling, pain, and fever. It is often used for conditions like arthritis, muscle pain, back pain, and dental pain. The tablet should be taken as directed by a doctor, preferably after food to avoid stomach irritation. Possible side effects include nausea, indigestion, or dizziness. Long-term or excessive use may affect the liver or kidneys, so medical supervision is important.
