I'm in a similar situation - I take immunosuppressants for an autoimmune condition and I struggled with recurring warts for quite a while. Like you experienced, the standard treatments just weren't effective for me. My dermatologist explained that because my immune system couldn't mount a strong response against the virus, we needed a treatment approach that would physically eliminate the wart tissue more completely. After trying several approaches without success, I was referred to a specialist who recommended removal of wart using laser technology. The specialist explained that this method could destroy the wart tissue and the blood vessels feeding it without relying as much on my immune response. I've now been wart-free for several months, which is the longest I've gone without new warts appearing since I started my immunosuppressant medication. If standard treatments aren't working for you, it's definitely worth exploring more advanced options that are specifically suitable for immunocompromised patients.
