<s>[INST] I am suffering from ankylosing spondylitis. I have been on enbrel (50 mg) a week for the past 3 months. My doctor is recommending i carry on taking the shots as it has helped me a great deal. How long should i continue and what are the possible side effects apart from the higher risks of infection? I am 36 years, married from India. [/INST] Hi, It will take from 6 months to one year you realize the complete recovery, no serious side effects are noted except for gastric disturbance. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Salah Saad Shoman, Internal Medicine Specialist </s>
