Diclofenac 50 mg is a common NSAID used to relieve pain and inflammation from conditions like arthritis and joint disorders. It works by blocking the enzyme that causes pain and swelling. Take it exactly as prescribed, ideally at the same time each day. While food doesn’t affect it, avoid alcohol, and don’t stop the medicine without your doctor’s advice. Store it in a cool, dry place out of children’s reach. 

Side effects can range from mild (like indigestion or dizziness) to serious (such as stomach bleeding, liver issues, or heart problems). It’s not recommended for people with ulcers, heart disease, or liver conditions. In case of a missed dose, take it as soon as you remember unless it’s almost time for the next one. If you suspect an overdose – look out for severe dizziness, stomach pain, or confusion- seek medical help right away.
