Once, back in the early days, just after the first lock down. DH had what was probably an asthma flare up and coughed himself silly until increased inhalers sorted it (2 to 3 days).
Since there was no testing unless you were hospitalised, I can't guarantee I'm right and once we'd committed we couldn't really back out.
DS and I were already at home and we were well stocked, the only inconvenience was getting hold of a couple of prescriptions.
