How Medications Can Mask Thyroid Issues

The reaction of antidepressants is mixed depending on the patient. Neuroleptic drugs (Seroquel and Zyprexa) are the most severe of such drugs.

Initially, health practitioners administered these drugs to treat schizophrenia but in recent times, they treat depression too. Their secondary effects include:

  • Gain weight
  • Develop diabetes
  • Socially withdrawn
  • Muscle jerks
  • Pain when contracting muscles
  • Severely drowsy

Neuroleptic drugs should be given in limited amounts or none at all, especially in adults.


The negative impacts of lithium on the thyroid are as listed below:

  • Increase the prevalence of thyroid autoimmune occurrences
  • May cause an underactive thyroid
  • Increased frequency of thyroid diseases and malfunctions
  • Malfunctioning of the thyroid especially during pregnancy which can turn out to be harmful to the unborn child

It is recommended, especially in the kitchen, for one to carry out reverse osmosis to exclude lithium from water.


Central hypothyroidism may develop after dopamine infusions. Dopamine restricts the release of TSH during low T3 and T4 levels, hence no thyroid hormone is produced. Adderall, Wellbutrin and Ritalin are drugs which mask a thyroid disorder. When tests are conducted, TSH levels appear to be normal but are dangerously low.

Thyroid medication functioning as antidepressants

In the results of the STAR*D survey, some of the people responded to T3 medication and not antidepressants, concluding that thyroid medication can act as antidepressants.


People on synthroid still experience depression and some doctors start antidepressant medication. Medication that has both T3 and T4 is more helpful in getting healthier.

Dosage recommendations

A patient should start from a low dose increasing it progressively until they find the most effective one. They should always go for frequent lab tests to gauge their recovery.

Side effects

  • Ill-temper and trembling
  • Hair loss
  • Irregular heart-beat
  • Sweating profusely

Medication with gluten

Some people react to gluten, especially with Celiac disease. Taking antibiotics will ease symptoms.

Medication with dye and lactose

Lactose free medicine such as tirosint is recommended. Some people are sensitive to both dyes and lactose impairing absorption of medication.
