While primarily known for treating tuberculosis, isoniazid is associated with potential ocular toxicity, leading to the crucial question: Can isoniazid cause vision problems? Studies have linked this antituberculosis drug to optic neuritis, a rare but serious side effect affecting the optic nerve.

Medically, several liquid agents can make parts of your body numb, including local anesthetics such as lidocaine and benzocaine. Historically, the first anesthetic properties were noted in the 1880s with cocaine, but today's modern pharmaceutical products offer safer, targeted pain relief for a wide range of medical and dental procedures.

According to case reports and pharmacological data, isoniazid, a primary medication for tuberculosis, can indeed cause optic neuritis, though it is a rare side effect. This visual toxicity is a serious but often reversible neurological complication linked to the drug's impact on essential vitamin metabolism.
