Amnesteem 40 mg vs. 80 mg. Just realized after 14 weeks my son has been taking wrong dosage

Question

My 17 year old son (weight 175) was prescribed Amnesteem, December 22, 2015, I just REALIZED he should be taking two pills daily (40mg x 2), instead of the 40mg. I will call our doctor tomorrow but realized this after the office had closed for the day. After reading some reviews, is it correct that he should remain on the 40 mg daily for 30 weeks instead of increasing to 80 mg (14 weeks complete)? he was supposed to take 80 mg daily for 20 weeks.

The correct dose for 175 lbs is 80 mg per day. He should take a total of 150 mg per kilo for course. In his case 12,000 mg total .

Accutane (isotretinoin) dosing is based on an individual's weight, which is 1 mg per kilogram for a minimum of 4 months. Therefore, since your son weighs 80 kg, his minimum recommend total dose will be isotretinoin 80 mg per day for four months. But if he can only tolerate 40 mg daily due to side effects or lab abnormalities, then his therapy will be for 8 months. Some providers prefer to start patients on lower doses to help patients acclimate to any side effects and to monitor for any changes in lab work.  I highly recommend you speak with his prescribing physician regarding your concerns about Accutane dosing and treatment. Take care and good luck.
