Can you have fat freezing if you're on immunosuppressant treatment? It’s aziothiaprine for rheumatoid arthritis

Yes, you should be able to have Coolsculpting while taking an immunosuppressant. CoolSculpting is a great option, because it is non-invasive with little to no down-time. Most patients opt to get re-treatments in the same area for maximum results of up to 40-50% fat cell reduction.  I suggest scheduling an in-person consultation with a physician so you can be evaluated and given recommendations.
