Hello, I'm only taking Low dose naltrexone 3mg at the moment, no tacrolimus. I also take magnesium chloride. It has to be chloride not sulfate. Also, vitamin D3 3000iu daily. I've only been on it for 2 weeks now and seeing improvements. My dermatologist also gave me mupirocin ointment to apply to the areas.
You need to avoid sugar and go on a low carb diet. Tomatoes also increase inflammation which is not good for hailey-hailey. I have had flares for the past year and doing these and taking my meds are really helping. First time in a yr that I'm not in severe pain and healing.
Good luck and I hope this helps. This is a terrible disease.
