Q: What is Cortigen? My doctor prescribed this drug due to my knee (patella tissue) problem. What are its side effects? My husband has been prescribed Hosit and Dolonex as his knee band is weak. What are its side effects?

A:Cortigen is the brand name of a herbal, non-prescription product, which is not designated or approved by the drug regulator. We are unable to comment on its safety or efficacy. Dolonex contains a non-steroidal anti-inflammatory drug (NSAID) called piroxicam, which is indicated to symptomatically relieve pain in osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, etc.
