Hi, You may be having telogen effluvium. There may be some cause like anaemia, vitamin deficiencies, minerals deficiencies, thyroid dysfunction, stress, sleeplessness, worries, etc. Investigations may be done to find out any cause responsible for the disease. Consult the dermatologist for the perfect diagnosis and proper treatment. Your doctor has given proper drugs which benefited you. You should continue the same medicines even after you get satisfactory result. In any case of hair fall. The good result takes few months to few years. So, do not stop the treatment. I do not think that acne,headache and sleepiness are due to the treatment. You should also inquire about them from your doctor and that should be treated. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ilyas Patel, Dermatologist
