Paracetamol 650 mg is a widely used pain reliever and fever reducer that belongs to the class of analgesics and antipyretics. It works by inhibiting cyclooxygenase (COX), a protein responsible for pain and fever. Commonly used to treat mild to moderate pain and fever, paracetamol is taken every 6 hours as needed, up to four times a day. However, it should be used with caution in individuals with liver disease or those who consume alcohol regularly, as excessive intake can lead to toxicity. 

While generally well-tolerated, some may experience side effects like nausea, vomiting, or stomach pain. It’s important to avoid interactions with medications like warfarin, phenytoin, and zidovudine, as well as certain foods like cabbage, which may interfere with its effectiveness. Always store the medicine at room temperature, away from sunlight and moisture, and keep it out of reach of children. If you miss a dose, take it as soon as you remember, unless it’s almost time for the next one. Overdosing (more than 4 grams per day) can lead to severe health complications, so always follow the prescribed dosage.
