Arnica 30 Overdose?
Posted: Mon Aug 13, 2012 8:03 pm
I was searching the net for most recent information about optic nerve atrophy and came across this. Seems very improbable. Had it happened in my country Pakistan and a large bottle of liquid Arnica 30 was consumed, it would have been easy to explain everything. I do not know about Indian liquor regulations so can't say much.

We report a case of acute, bilateral and severe vision loss after inadvertent consumption of a large quantity of the homoeopathic medication Arnica-30. Severe vomiting which required hospitalization preceded visual symptoms. In the acute stage, pupillary responses to light were absent and fundus examination was normal. Vision loss followed a fluctuating course, with profound loss noted after 6 weeks along with bilateral optic disc pallor. Neuro-ophthalmic examination and detailed investigations were performed, including magnetic resonance imaging, electroretinography (ERG) and visual evoked potentials (VEP). Ocular coherence tomography (OCT) showed gross thinning of the retinal nerve fiber layer. While a differential diagnosis of posterior ischemic optic neuropathy was kept in mind, these findings supported a diagnosis of bilateral toxic optic neuropathy. Arnica-30 is popularly used to accelerate wound healing, including after oculoplastic surgery. While homeopathic medicines are generally considered safe due to the very low concentrations involved, Arnica-30 may be neurotoxic if consumed internally in large quantities.
