The Thyroid is contra-indicated in tuberculous persons, as they are apt to lose quickly in weight, over two pounds in twenty-four hours.
Rheumatic and anæmic symptoms are more frequently aggravated than improved.
As the Thyroid is a powerful remedy, the following should be always remembered:
There is a decided difference with regard to individual toleration, some are very susceptible.
The pulse should be watched regarding frequency and quality. The least effort or exertion will increase it even to 160, hence some cases should be kept in bed or at least very quiet and tranquil even for a time after the remedy has been discontinued. Deaths have taken place after a few days' treatment.
If Thyroid is not taken for myxœdema the patient should be weighed at least every two weeks, and if pathogenetic symptoms, called thyroidism, appear the remedy should be discontinued or reduced.
If softening of the bones has been caused it may be necessary to restrict the use of the legs or to use splints.
Thyroid seems to have a cumulative effect.
In many cases a liberal diet should be prescribed to avoid injurious consequences.
