Hi, hope you are doing great.

The dose of isotretinoin varies depending on the body weight and one full course is for 20 weeks. The dose can be continued till all the existing acne have gone and formation of new ones has been stopped. Therefore, it may take upto an year. Despite all this, if there is a relapse, the cycle needs to be started again
