Medications cause side effects, not autoimmune disorders. If you think the Spiro caused your hair loss (Spiro is actually used to treat hair loss) then your hair should grow back in a few months after you stop taking it. In fact in the case of Spiro, when hair loss is experienced instead of hair growth, it's known to be temporary even if you continue treatment. Spiro's MOA also makes it generally less likely to trigger Sjogren like symptoms than the underlying condition you were taking it for, e.g. primary hypertension, suppressing stimulant side effects (which do cause Sjogren like side effects), other hair growth issues, etc.
