Isotretinoin is a drug that needs care on the part of the doctor when prescribing.
Firstly, it is teratogenic (causes malformed fetuses) thus a female patient CANNOT and MUST NOT get pregnant while on the pill (and 3-6 months thereafter to be safe).
Secondly, it has possible side effects. Disturbances of your lipid levels, renal and liver function may be possible and blood monitoring must be observed for safety’s sake.
Thirdly, it can cause really dry skin and mucous membranes (lips) etc.
All the above occur much more often in patients on a higher dose. Therefore, I can understand why your doctor is very cautious on the dosage. I would suggest for you to be patient and follow the doctor’s advice, if not, go for a second opinion.
