20 Astonishing Reasons Why Your Muscle Relaxers Might Not Be Your Friend

17. Liver Toxicity (Hepatotoxicity): The Silent Organ Strain

Certain muscle relaxers, like Tizanidine or Baclofen (especially at higher doses or with prolonged use), can surprisingly cause liver toxicity. This insidious damage is often silent in its early stages, with symptoms only appearing once significant liver compromise has occurred. Regular liver function tests are crucial for patients on long-term therapy to monitor for elevated liver enzymes, which signal stress or damage to the organ. Understanding this potential for hepatotoxicity underscores the need for careful medical oversight and periodic blood work.

18. Exacerbation of Glaucoma: The Ocular Pressure Threat

For individuals with certain types of glaucoma (specifically narrow-angle glaucoma), muscle relaxers with anticholinergic properties can pose a serious, hidden threat. These medications can cause dilation of the pupils, which can narrow the drainage angle in the eye, potentially leading to a sudden, dangerous increase in intraocular pressure. This acute glaucoma attack can cause severe eye pain, blurred vision, and permanent vision loss if not immediately treated. Always disclose a history of glaucoma to your doctor before starting a muscle relaxer.
