Taking Nucort M8 (methylprednisolone) daily for 2-3 years is unsafe. Long-term steroid use can cause severe complications like bone thinning, diabetes, high blood pressure, and adrenal gland suppression. Your rapid symptom return indicates steroid dependence; do not stop taking it abruptly, as this can trigger a dangerous adrenal crisis. You must consult a dermatologist immediately to safely and gradually taper off this medication. Safer, long-term alternative treatments include non-steroidal topical creams (like tacrolimus), antihistamines, targeted biologics, or steroid-sparing immunosuppressants, depending on your specific skin diagnosis.
