###Human: Is there a permanent remedy to get rid of psoriasis? ###Assistant: Hello. Isotretinoin is a potentially dangerous drug and in many countries there are very strict guidelines over its use. It basically contains retinoids which in simple language is a derivative of vitamin A. It is primarily used to treat severe cystic acne and I fail to understand why your doctor has prescribed it to you for psoriasis. Its side effects include: Well, I need some more information: 1) For how long have you been suffering from scalp psoriasis? 2) Exact name and exact dose of the medicines which you are taking? 3) For how long have you been taking each medicine (in detail)? 4) Any medicine which you had taken in the past but not taking now? 5) Do you feel any side effects which I have mentioned above? 6) How much relief have you got in your scalp psoriasis from these medicines or no effect at all yet? 7) Do you have psoriatic lesions anywhere else on the body or just on scalp? Kindly provide these information, so that we can evaluate your case in detail and prescribe you with the best possible treatment. Revert back to a dermatologist online for further follow up -->
