Fenclofenac Explained
Fenclofenac is a nonsteroidal anti-inflammatory drug (NSAID) previously used in rheumatism. It has mild immunosuppressive effects[1] and may displace thyroid hormone from its binding protein.[2] [3] It can also cause lichen planus.[4]
Due to its side effects it was withdrawn from the UK and US in the 1980s.
