Hello and welcome to healthcaremagic
For
severe acne OR for acne unresponsive to traditional anti-acne medications,
Isotretinoin is the drug of choice. It the only drug which offers any chance of long term cure and after a full course of isotretinoin significant number of people never have a recurrence of there acne. However it should be given in the right dose and for the right duration.
Total Cumulative dose of Isotretinoin that should be taken is 120-140mg/kg.
For a complete course in e.g a 60 kg man it comes out to be 12 months of 20mg, once daily or 6 months of 20mg, twice daily. The chances of relapse are more likely, if the course is incomplete.
I normally start Isotretinoin at 20mg and make it 40 mg after a month, which i continue till the total cumulative dose has been given (i.e 120-140mg/kg)
Moreover, while you are on oral isotretinoin, your
Lipid profile and Liver function tests need to be monitored at regular intervals, therefore it is all the more necessary to follow up with a
dermatologist while you are on Isotretinoin.
In addition to Isotretinoin, the oral antibiotic (Azilide) can be continued for 4-12 weeks depending on the response.
In addition to oral retinoids and
oral antibiotics you must also use topical antiacne remedies e.g
benzoyl peroxide gel OR Clindamycin+
nicotinamide gel.
