A convoluted trail led me back to ADHD and the treatment drugs that raise the dopamine levels by blocking the receptors. Like Ritlin and a dozen others.

Which was a link at this site when investigating thyroid function, or rather possible disfunction.

These medications can complicate your clinical picture and make determining how to proceed with thyroid dosing difficult.

Medications which are known to lower your TSH include:

Glucocorticoids (5) (which includes steroids such as prednisone) - Frequently used to treat inflammatory conditions and autoimmune diseases.
Dopamine agonists - Often used to treat Parkinson's disease.
Somatostatin analogs (6)- Used in rare forms of cancer to block hormone production.
Metformin (7)- Used to treat insulin resistance and type II diabetes mellitus.


This is a distressing list of side effects-- it includes all the 4 types above, and not separated out by drug. I recognize some of these problems as connected to the ADD drugs.


Side effects
Some of the common side effects of dopamine agonists include:[8][9]

Euphoria
Pericardial effusion
Fibrous thickening of lining that covers some of the internal organs including the heart or the lungs (fibrotic reaction)
Hallucinations
Causing or worsening psychosis
Orthostatic hypotension
Increased orgasmic intensity
Weight loss
Anorexia (symptom)
Nausea and possible vomiting
Insomnia
Unusual tiredness or weakness
Dizziness
Drowsiness
Possible Narcolepsy manifestations (Sleep attacks)[10]
Lightheadedness
Raynaud's phenomenon (common side effect of ergot derivatives)
Syncope
Twitching, twisting, or other unusual body movements
Pathological addiction (gambling, shopping, internet pornography, hyper-sexuality) – specifically D3-preferring agonists
After long-term use of dopamine agonists, a withdrawal syndrome may occur, during dose reduction or discontinuation, with the following possible side effects: anxiety, panic attacks, dysphoria, depression, agitation, irritability, suicidal ideation, fatigue, orthostatic hypotension, nausea, vomiting, diaphoresis, generalized pain, and drug cravings. For some individuals, these withdrawal symptoms are short-lived and make a full recovery, for others a protracted withdrawal syndrome may occur with withdrawal symptoms persisting for months or years.[11]



Some medical drugs act as dopamine agonists and can treat hypodopaminergic (low dopamine) conditions; they are typically used for treating Parkinson's disease (PD), Attention deficit hyperactivity disorder (in the form of stimulants) and certain pituitary tumors (prolactinoma), and may be useful for restless legs syndrome (RLS). Both ropinirole and pramipexole are FDA-approved for the treatment of RLS. There is also an ongoing clinical trial to test the effectiveness of the dopamine agonist ropinirole in reversing the symptoms of SSRI-induced sexual dysfunction.[6]
