First off I would leave your son on his current dose. The side effects aren't really avoidable. With my experience on Accutane most of the initial side effects vansihed after being on Accutane for a few weeks.
As for petroleum jelly in the nose ... don't do it. Putting petroleum products in the sinus passages where the product can be breathed in can cause pneumonia. I recommend using saline gel nasal spray.
I had to use the following products while on Accutane.
Vaseline for lips
Saline Gel for nose
Synthetic tears for my eyes (They were dry and would sting)
I used several different types of moisturizers for my skin (Use only water based creams) moisturizers that are alcohol based will only dry the skin even more.
Get a good conditioner. I used Pantene hair mask and Herbal Essence Hello Hydration. The hair and scalp will get very dry and the hair will be super course and fluffy unless a good balance of moisture is maintained.
Make sure he takes the Accutane with the largest most fatty meal of the day or the Accutane will NOT work.
I never experienced an initial breakout at all. It will be hard for him to do but the second he takes the first pill tell him not to wash his face with ANYTHING except water. If he uses other products he will burn his skin and dry it out severely.
Try to avoid long, hot baths. It's best to take a cool shower and pat dry the skin afterwards. You can also get Vaseline Coco butter baby oil gel. I would rub that on my body after a shower.
I neglected my skin when I first started taking Accutane and developed Accutane induced dermatitis rashes all over my arms. I was given a steroid and started using the baby oil and it cleared up in a couple weeks.
I got mild nose bleeds and headaches initially but they too went away with time.
You will hear the side effects are harsh and a lot of people quit taking it because of the initial side effects. STICK WITH IT! The side effects will fade except for the dry skin.
I had acne form the time I was around 13 and I am finally acne free as of last year and I am almost 30. Accutane was the best decision I have ever made in my life and I am so thankful for the drug!
