What statement indicates a likely contraindication for administering tricyclic antidepressants?

The statement that indicates a likely contraindication for administering tricyclic antidepressants is "I had a myelogram yesterday." This is pertinent because tricyclic antidepressants can interact adversely with certain diagnostic procedures and may increase the risk of complications. Following a myelogram, a procedure that involves injecting a contrast dye into the spinal canal, there may be concerns regarding the potential for an increased risk of adverse effects if tricyclic medications are used shortly after the procedure.

Myelograms can involve changes in fluid dynamics and increased sensitivity in the central nervous system, which can be further complicated by the sedative and anticholinergic properties of tricyclic antidepressants. These properties can lead to excessive sedation or other neurologic symptoms if administered too soon after the procedure, making it prudent to wait a certain period before prescribing them.

Other statements, while related to health conditions that warrant caution, do not constitute direct contraindications in the same way. An enlarged prostate and glaucoma can potentially pose risks with tricyclics but are typically managed with caution rather than outright contraindications. Similarly, concerns about kidney function might require dosage adjustments rather than completely barring the medication.
