Which of the following drugs is included in the MRS DICE mnemonic for optic neuritis?

The drug included in the MRS DICE mnemonic for optic neuritis is Isoniazid. This mnemonic is used to remember potential causes of optic neuritis, with each letter representing a specific risk factor or contributing drug.

Isoniazid, an antibiotic commonly used to treat tuberculosis, can lead to optic neuropathy as a side effect, which is why it is part of the mnemonic. Optic neuritis itself refers to inflammation of the optic nerve, and certain medications, infections, or toxins can contribute to its development. Other drugs listed in the mnemonic may include those that have similar effects or are associated with the condition, helping users recall critical information related to optic nerve health and the potential drugs that warrant caution in patients.

The remaining options are not included in the mnemonic as they either do not directly relate to optic neuritis or lack a clear association with the inflammation of the optic nerve as seen with Isoniazid.
