I can answer only your first question. Diclofenac tablets are an anti inflamatory and pain killing tablet, I take them for an arthritic condition. As for their use for Asthma, I hope someone else will answer. I note this is a different Diclofenac.

Other than that, you should ask your own doctor about it, we don't know your medical history.

Diclofenac is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Diclofenac works by reducing hormones that cause inflammation and pain in the body.

Diclofenac is used to treat pain or inflammation caused by arthritis or ankylosing spondylitis.

Diclofenac may also be used for other purposes not listed in this medication guide.
