Diclofenac, sold under the trade names Voltaren among others, is a nonsteroidal anti-inflammatory drug used to treat pain and inflammatory diseases such as gout. It is taken by mouth or applied to the skin. Improvements in pain typically occur within half an hour and last for as much as eight hours.
Paracetamol, also known as acetaminophen and APAP, is a medication used to treat pain and fever. It is typically used for mild to moderate pain relief. There is mixed evidence for its use to relieve fever in children. It is often sold in combination with other medications, such as in many cold medications.
