Which condition is a contraindication for the use of anti-sialogues?

• A. HIV
• B. Addison's disease
• C. Glaucoma
• D. Hypothyroidism

Answer: (C)

The condition that is a contraindication for the use of anti-sialogues is glaucoma. This is due to the fact that many anti-sialogues, such as atropine, can cause dilation of the pupil (mydriasis) and may lead to increased intraocular pressure, which can aggravate glaucoma—a condition characterized by increased pressure within the eye that can lead to vision loss if not managed properly. Thus, prescribing anti-sialogues in patients with glaucoma poses a significant risk to their eye health.

In contrast, the other conditions listed (HIV, Addison's disease, and hypothyroidism) do not present the same direct risks concerning the effects of anti-sialogues on intraocular pressure or eye health. While these conditions may require careful management in the context of other medications and health factors, they do not inherently contraindicate the use of anti-sialogues as glaucoma does.
