Adalimumab also may worsen the symptoms of diseases of the nervous system. In studies some patients who used adalimumab or other TNF blocking drugs developedcancer.Since patients withrheumatoid arthritishave a higher rate ofcancersthan the general population, the connection betweencancerand use of adalimumab is unclear.
