Ans: Diclofenac is a non-steroidal anti-inflammatory drug. It works on the body by reducing triggers that cause pain. It is often used to treat pain or inflammation for patients with arthritis or ankylosing spondylitis. Paracip and Diclofenac can be taken together. However long-term use of both pain killers can cause severe heartburn, long-term acid reflux, stomach bleeding, and ulcers.
