What disorder would indicate a need to contact the health care provider before administering cyclobenzaprine?

Cyclobenzaprine is a muscle relaxant that is primarily used to relieve muscle spasms and discomfort. One of the important considerations when administering cyclobenzaprine is its potential to increase intraocular pressure, which can pose a risk for individuals with glaucoma. Glaucoma is characterized by elevated pressure within the eye that can lead to damage of the optic nerve and vision loss.

In patients with glaucoma, especially narrow-angle glaucoma, the use of cyclobenzaprine may exacerbate their condition by causing further increases in intraocular pressure, which can lead to acute glaucoma attacks. Therefore, it is crucial to contact the health care provider before administering cyclobenzaprine to anyone with a history of glaucoma to evaluate the risks and consider alternative treatment options.

While the other conditions listed—emphysema, hyperthyroidism, and diabetes mellitus—have their own considerations, they do not directly interact with cyclobenzaprine in the same way that glaucoma does concerning intraocular pressure. Hence, the urgency of contacting a healthcare provider is most pertinent in the case of a patient with glaucoma.
