Fenak Plus Tablet is a combination analgesic and anti-inflammatory medication containing Diclofenac 50mg and Paracetamol 325mg, designed to provide effective relief from pain and inflammation. Diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), works by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins responsible for pain, swelling, and fever. Paracetamol, also known as acetaminophen, acts centrally to alleviate pain and reduce fever by inhibiting prostaglandin synthesis in the brain. Together, these active ingredients offer synergistic effects, making Fenak Plus suitable for managing various conditions such as musculoskeletal pain, arthritis, dental pain, postoperative pain, and headaches. The combination ensures rapid onset of pain relief while minimizing the dose-related side effects associated with higher doses of either component alone. Fenak Plus is typically administered orally and should be used as directed by a healthcare professional to avoid potential adverse effects such as gastrointestinal irritation, liver toxicity, or allergic reactions. It is contraindicated in patients with known hypersensitivity to NSAIDs or paracetamol, active peptic ulcers, severe liver or kidney impairment, and should be used cautiously in individuals with cardiovascular risks. Overall, Fenak Plus Tablet is an effective option for short-term management of acute pain and inflammation.
