Welcome you to healthcaremagic community forum. Takayasu's disease is one of the inflammatory conditions affecting large arteries. Since this is a chronic condition, the treatment will be a chronic one. Apart from the steroids
, cytotoxic drugs, immunomodulators are other class of medications that are used for treatments. Steroids form the first line of treatment as they are more effective treatment and its side effects compared to other class is less significant. Other drugs are used if steroids are ineffective. I would recommend you to continue with the steroid therapy as suggested by your doctors. Surgical options are the only remaining other option if you do not wish to use these medications, however, the feasibility has to be discussed with your doctor.. I understand what is going through both physically and emotionally, but do not lose hope. Things are not doomed. You will be able to lead life as normally as possible with regular treatment. Wishing you a bright future..
