The organic compound isoniazid can be found in a drug that was formulated way back in the 1930s when the disease tuberculosis was running through the lands of the world and killing people indiscriminately. However because of the research done by science and the after effects of technological advancement from the First World War isoniazid was a discovery that altered the face of the always changing planet. The use of the drug other than to fight tuberculosis can cause problems such as liver damage that is not repairable. It should be known however that the use of the drug on its own to fight this terrible disease will only cause more damage.
The drug isoniazid is what medical staff call an active drug that actively goes around the body on what might be best called a search and destroy mission. Without bacterial influence the drug will not take any effect however once in the body there is no way that the bacteria could not reach the drug to set off the reaction. Like many drugs the use of this particular drug does come with side effects such as the above mentioned liver problems. Hepatitis is also a common symptom of using isoniazid and the central nervous system can be affected as well.
