Paracetamol is the active ingredient in Adol, which is used as a pain reliever and fever reducer. It comes in several forms including caplets, tablets, suppositories, and liquid suspensions and syrup. The drug works by reducing pain and fever through effects in both the central and peripheral nervous systems. It is generally well-tolerated but overdose can cause liver damage and should be avoided. Proper dosage depends on age, and the drug should be used as directed by a medical professional.
