Which appetite medication should be used with caution in patients with anxiety?

• A. Metformin
• B. Orlistat
• C. Phentermine/topiramate with caution
• D. Liraglutide

Answer: (C)

Appetite suppressants that stimulate the central nervous system can worsen anxiety symptoms. Phentermine acts as a stimulant, increasing norepinephrine and dopamine in the brain, which helps reduce appetite but can also raise anxiety, cause jitteriness, and disturb sleep. When you add topiramate, the combination remains effective for weight loss but still carries that stimulant-related potential to heighten anxiety, so it should be used with caution in patients who have anxiety. The other options work differently. Metformin is a diabetes medication with little direct effect on appetite or CNS activity, so anxiety isn’t a primary concern. Orlistat works in the gut to block fat absorption and doesn’t affect the central nervous system. Liraglutide, a GLP-1 receptor agonist, influences appetite through hormonal signals and can cause gastrointestinal side effects, but it isn’t known for exacerbating anxiety in the same way a stimulant-containing therapy does. So the choice that should be used with caution in anxious patients is the stimulant-based combination, due to its potential to worsen anxiety.
