Wellfast Tablet is a combination analgesic and anti-inflammatory medication containing Aceclofenac 100 mg and Paracetamol 325 mg. Aceclofenac, a non-steroidal anti-inflammatory drug (NSAID), exerts its therapeutic effect by inhibiting cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain, inflammation, and fever. Paracetamol, an analgesic and antipyretic agent, provides additional pain relief and fever reduction through central inhibition of prostaglandin synthesis. This synergistic combination is indicated for the management of mild to moderate pain associated with musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and soft tissue injuries. Wellfast Tablet offers effective relief from joint pain, inflammation, and stiffness, improving patient mobility and quality of life. It is generally well tolerated; however, caution is advised in patients with a history of gastrointestinal ulcers, hepatic or renal impairment, and hypersensitivity to NSAIDs or paracetamol. Common adverse effects may include gastrointestinal discomfort, nausea, or allergic reactions. Wellfast should be administered as directed by a healthcare professional, with the lowest effective dose used for the shortest duration necessary to minimize potential side effects. Regular monitoring is recommended during prolonged therapy to ensure safety and efficacy.
