White Shark- In the article they did not give the medication a significant amount of time. Also keeping in mind that while he was on the medication he still kept physically manipulating his lips. When taking something like Imuran my doctor suggests I stay on it for a reasonable amount of time until I get completely better (around 4 months for me) longer than the time alotted in the article. And no it is not a forever medication. Just until you get better.
