Springer 19 Bergin PS, Bronstein AM, Murray NMF, Sancovic S, Zeppenfeld K. Body sway and vibration perception thresholds in normal aging and in patients with polyneuropathy. As a rule of thumb, neurotoxicity has become rarer as lower amiodarone maintenance doses are in use (≤5%).
Cough, new chest infiltrates in imaging studies and reduced lung diffusing capacity in the appropriate clinical setting of amiodarone use, after the meticulous exclusion of infection, malignancy and pulmonary oedema, are the cardinal clinical and laboratory elements for diagnosis. Because amiodarone-induced polyneuropathy has a characteristic “demyelinating” pattern with reduced nerve conduction velocities, a neurology consultation might be able to pinpoint the most likely aetiology [9].
The frequency of neurotoxicity is reported to be in the range of 35% to over 50% in older publications and ≤5% in more recent ones [4–6]. When I left the hospital I was given the Amiodarone (prescription 200 mg). As always when treating geriatric patients, there might be more than one cause for the dizziness.
Muscle weakness (which can be caused directly by myopathy and/or indirectly via polyneuropathy).
JAMA. Three different and intertwined mechanisms of lung toxicity have been suggested: (i) a direct toxic effect; (ii) an immune-mediated mechanism; and (iii) the angiotensin enzyme system activation. For authors

I would like to offer my special thanks to Dr Yvonne Brun-Odermatt, consultant cardiologist at the Kantonsspital Uri, for her review of the manuscript. Take my advise and stay away! 1 Epstein AE, Olshansky B, Naccarelli GV, Kennedy JI, Murphy EJ, Goldschlager N. Practical management guide for clinicians who treat patients with amiodarone. Readers who want to go into more detail about clinical polyneuropathy assessment can consult current diabetes guidelines [20]. Praxis.

Reviews that appear to be created by parties with a vested interest in the medication will not be published. 9 Anderson NE, Lynch NM, O’Brian KP.
The author declares that there are no conflicts of interest, in particular none with a manufacturer of pharmaceutical products or a competitor. The pharmacology and toxicities are also reviewed. The following information is NOT intended to endorse any particular medication. After 2 years he complained of weakness in his legs and loss of dexterity in his hands. When taking a history, even patients with frank weakness might use the word “dizziness” to describe their symptoms! Pulmonary involvement falls into two categories of different grades of clinical significance: (i) the ubiquitous 'lipoid pneumonia', the so-called 'amiodarone effect', which is usually asymptomatic; and (ii) the more appropriately named 'amiodarone toxicity', which includes several distinct clinical entities related to the differing patterns of lung inflammatory reaction, such as eosinophilic pneumonia, chronic organizing pneumonia, acute fibrinous organizing pneumonia, nodules or mass-like lesions, nonspecific interstitial pneumonia-like and idiopathic pulmonary fibrosis-like interstitial pneumonia, desquamative interstitial pneumonia, acute lung injury/acute respiratory distress syndrome (ARDS) and diffuse alveolar haemorrhage.
2009;9:106–7. Whereas most physicians will be familiar with the risk of thyroid dysfunction during anti-arrhythmic therapy with amiodarone, potential neurotoxicity is less well known among its numerous other side effects [1].
And in the long run, polyneuropathy increases the risk of amputations. 13 Abarbanel JM, Osiman A, Frisher S, Herishanu Y.
Should only be taken if you tried other drugs and they didn't work.

Neither Everyday Health nor its licensor assume any responsibility for any aspect of healthcare administered with the aid of the information provided. The patient is asked to stand with feet together and then to close his/her eyes. eCollection 2020.Aust Prescr. Treatment with amiodarone is usually long-term unless you experience an adverse effect.
If the test is already positive with eyes open, then the patient will probably refuse testing with eyes closed and you might dispense with this step altogether. Two important publications from 1974 illustrate many of the typical aspects of amiodarone neurotoxicity. It was highly effective but after 12 months the side effects were severe.
J Am Coll Cardiol. I developed a very bad cough within a week. Therefore, our aim was to do a systematic review of the effect of amiodarone in patients with Chagas disease, to provide a more accurate estimate of the effect of amiodarone in this population and to identify the potential benefits and harms of this drug. Typically, amiodarone-induced neurotoxicity has an insidious onset. – Amiodarone can cause “dizziness” at various levels of the nervous system: (1) optic neuropathy, (2) distal-symmetric polyneuropathy, (3) cerebellar toxicity, (4) peripheral vestibulopathy, and (5) myopathy.
