Isoniazid therapy may need to be continued for up to 9 months. Your doctor will decide that.
It is extremely important to take dose as directed. Take all of the isoniazid that has been prescribed for you even if you begin to feel better. Your symptoms may begin to improve before the infection is completely treated. It is important to take isoniazid regularly to get the most benefit.
