Refractory
Not responding to the usual treatments — a description of the condition, not of you.
What it means
A condition that has not improved despite standard treatment being tried properly.
It is a statement about the illness, not about you. It does not imply you failed to take the medication, and it is worth saying that because the word reads like an accusation.
It usually opens doors rather than closing them — refractory is often the label that qualifies someone for specialist referral or second-line treatment.
In practice
In letters about epilepsy, asthma, depression, hypertension and inflammatory conditions, among others.
"Treatment-resistant" means the same thing, and is more commonly used in mental health.
Why it matters
Ask what comes next, since the label usually exists to justify escalating.
Ask whether the diagnosis itself should be revisited. Occasionally a condition is refractory because it is something else.
Mention anything about how you actually took the treatment, honestly — side effects, missed doses, stopping early. That changes the interpretation entirely and nobody will judge it.
