Since antihistamines and steroids only provide temporary relief for your 9-year chronic itching, we must target the underlying cause, which may be neuropathic or systemic. For long-term relief, alternative prescription options include neuromodulators like Gabapentin or Pregabalin, which quiet overactive itch-sensing nerves. Other effective alternatives include tricyclic agents like Doxepin or opioid antagonists like Naltrexone. I highly recommend consulting a dermatologist or allergist to run comprehensive blood tests (checking kidney, liver, and thyroid function). They can help identify the root cause and safely prescribe these targeted, non-steroidal therapies for lasting relief.
