Nimulid is the brand name. The name of the medicine is nimesulide. Its major side effects include: Dizziness, peptic ulcers, perforation or gastro-intestinal bleeding, urticaria, pruritus, erythema, angioedema (accumulation of fluid in the body), liver injury that may lead to fatal outcome, acute hepatitis, fulminant liver failure, oliguria (reduced production of urine), haematuria (blood in urine), etc.
Even though the drug was discovered in US, its use is not permitted in America and most other advanced countries like Britain, Japan, Canada, Australia etc.
It is dangerous to use the drug since some patients in Finland have died due to liver failure induced by nimesulide.
Brufen (ibuprofen) is far more safe.
