Fensupp 100 Suppository contains Diclofenac 100mg, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. It is commonly prescribed for conditions such as arthritis, musculoskeletal injuries, postoperative pain, and other inflammatory disorders. Diclofenac works by inhibiting cyclooxygenase (COX) enzymes, which play a key role in the synthesis of prostaglandins responsible for pain and inflammation. The suppository form allows for rapid absorption through the rectal mucosa, making it suitable for patients who cannot take oral medications due to nausea, vomiting, or difficulty swallowing. Fensupp 100 is typically administered once or twice daily, depending on the severity of symptoms and physician recommendations. It should be used with caution in patients with gastrointestinal disorders, cardiovascular disease, or renal impairment, as NSAIDs can increase the risk of adverse effects such as ulcers, bleeding, hypertension, and kidney problems. Patients are advised to follow the prescribed dosage and duration to minimize side effects. Common adverse reactions may include mild rectal irritation, nausea, or dizziness. Fensupp 100 Suppository should be stored in a cool, dry place, away from direct sunlight and out of reach of children. Always consult a healthcare professional before starting treatment.
