Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
As per your explanation, it looks like you had a severe side effect of medicine leading to ulceration in the mouth with pain, inflammation, and ulcers on the skin with hair loss. So my suggestion is that as you have stopped taking the medicine, the symptoms will gradually subside.
Also to reduce pain and inflammation inside the mouth, you can gargle with the specialized mouthwash like Magic mouthwash, suck ice pops or do cool water rinses, suck Cepacol lozenges and take vitamin B complex daily.
For sores on skin apply antiseptic ointment over them and if there is itching apply
Caladryl lotion and do cool compresses. For hairs
massage the
scalp with olive oil and take Indian Gooseberry powder with water daily.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
