Allergic reaction to Accutane? Red and small bumps on and around the lips (Photo)

I've been accutane for one month. I weigh 50 Kg and taking 50 mg. However, my lips are suffering to the point where I am worried that I may be allergic. I had to stop taking it in week 3 for two days because I woke up with swollen red lips with small bumps everywhere on it. A week later, my lips became extremely red again, but this time the skin around them developed these small bumps and the skin was very dry, itchy, red and tight. My lips are constantly burning and tingling everyday.
