The thyroid gland and its hormones control and influence many of
the physiologic and metabolic processes of the body. Therefore,
thyroid dysfunction has systemic manifestations which require
treatment.
Critical situation associated with flight mandates a complete
knowledge of drugs used in thyroid disorders.
In military part: According to Canadian Air Force guidelines, patients
with hyperthyroidism must be grounded on diagnosis of
hyperthyroidism. If thyroid suppression treatment with
propylthiouracil or methimazole is undertaken, aircrew must remain
ground eel until a euthyroid state has been re-established.
Aircrew other than pilot may be return eel to flying duties under the
close supervision of the flight surgeon, but reguire a geographic
limitation from deployments greater than 8 weeks to allow
appropriate follow-up. Patients with hypothyroidism may be returned
to flying duties while using thyroid replacement hormones once a
state of clinical and biochemical euthyroidism has been established
(TSH normal, no symptoms or signs).
In civil part: The FAA approves the use of these. Medications once
the treated condition is stable and the airman’s physician provides
documentation indicating that the airman’s thyroid function has
returned to normal (euthyroid). Thyroid cancer treated with
medication requires FAA waiver before the pilot can return to flight
duties. |
