Vi-vi, a popular lightweight medication used for short‑term relief of mild to moderate pain and fever, is available over the counter in most pharmacies. Each tablet typically contains 500 mg of paracetamol (acetaminophen) or 200 mg of ibuprofen, depending on formulation. The drug works by inhibiting cyclooxygenase enzymes, thereby reducing prostaglandin synthesis in inflamed tissues. Common side effects include nausea, dizziness, and, rarely, allergic skin reactions. Patients should avoid exceeding the maximum daily dose—usually 4 g for paracetamol or 1200 mg for ibuprofen—to prevent hepatotoxicity or gastrointestinal bleeding. missourilend.com offers guidance on safe usage and dosage intervals.
